Command:AALIGN (AA)

MS2000 or RM2000 syntax
Shortcut AA
Format AALIGN [axis] = ### …
Units 0-99, hardware potentiometer value
Tiger syntax
Shortcut AA
Format AALIGN [axis] = ### …
Units 0-99, hardware potentiometer value
Type Axis-Specific

Adjusts the drive strength by writing to a non-volatile on-board potentiometer. Normally done once at the factory and never adjusted again. After changing the value the AZERO command should be run.

WARNING – The stage may move when the AALIGN command is sent.

Example
AA X? Y? Z?			
:A X=83 Y=78 Z=59

Queries the current AA parameters. 

AA X=85				
:A

Sets the X axis potentiometer to 85.

Shortcut AC
Format ACCEL [axis] = [time in msec]…
Units millisecond
Remembered Using SS Z
Tiger syntax
Shortcut AC
Format ACCEL [axis] = [time in msec]…
Units millisecond
Type Axis-Specific
Remembered Using [addr#]SS Z

This command sets the amount of time in milliseconds that it takes an axis motor speed to go from the start velocity to the maximum velocity and then back down again at the end of the move. At a minimum, this acceleration / deceleration time must be greater than t_step (the amount of time it takes for the controller to go through one loop of its main execution code; the INFO command shows t_step).

Example
AC X=50 Y=50 Z=50
:A
AC X? Y? Z?
:X=50 Y=50 Z=50 A

The command in this example will make the controller take 50 milliseconds to accelerate the motors on each axis during a move command. When the controller gets within 50 milliseconds of finishing the move, it will begin to decelerate the motors back down to the start velocity where the pulses take over to bring the axes within the pulse crossover position error.

Command:AFADJ

MS2000 and RM2000 Syntax
Shortcut AFADJ
Format AFADJ [X= zero pot value] [Y= video amplitude value] [Z= value]
Units integer
Remembered Using SS Z
Tiger Syntax
Shortcut AFADJ
Format [Addr#]AFADJ [X= zero pot value] [Y= video amplitude value] [Z= value]
Units integer
Type Card-Addressed
Remembered Using [Addr#]SS Z

X & Y values range between 0 and 100. Y determines amplitude of the video signal entering the system. Setting a 0 value attenuates a video signal completely, while a setting of 100 lets the full signal go through. Attenuating a video signal also reduces the noise in the signal. If the focus value on the LCD reads 2047, then the system is saturated with too much signal, try reducing the Y value.

X is the zeroing potentiometer; the value of X should be set such that, when Y is 0, the focus value is also 0000 (or as close as possible).

Z sets the gain of the final Analog to Digital Converter (ADC) in the auto-focus system. Range: 0 to 3. By adjusting this setting, a focus value for a sparse sample can be magnified to get better focus. If an incorrect value of gain is used, the ADC saturates and the focus value reaches 2047. Upon system restart, the setting returns to its default value of 0. Perform an SS Z command to save the current gain setting in non-volatile memory.

Command:AFCALIB (AFC)

MS2000 and RM2000 Syntax
Shortcut AFC
Format AFCALIB [X= contrast] [Y= frame offset] [F= switch axis]
Units integer
Remembered Using SS Z
Tiger Syntax
Shortcut AFC
Format [Addr#]AFCALIB [X= contrast] [Y= frame offset] [F= switch axis]
Units integer
Type Card-Addressed
Remembered Using [Addr#]SS Z

The command without arguments will initiate series of auto-focus scans and selects various internal parameters for best focus value. Parameters changed by AFCALIB are the Highlighted Area (AFLIM), Zero Adjust (AFADJ), and ADC Gain (AFADJ). On some focus controllers, the AFCALIB routine can also be activated by holding down the HOME button for longer than 3 seconds. The AFCALIB’s auto-calibration scans use the same speed and travel distance value that were set by the AFOCUS command. NOTE: Please use the HALT command or the \ to cancel an auto calibration – any other method may stop the move but may corrupt your settings.

X= Sets the minimum contrast value. During an auto-focus run, if the controller finds the difference between the maximum and minimum focus value to be less than the contrast value, it declares the run a failure and returns to the starting position. Default value is 10.

Y= Frame Offset, a floating-point constant that maps to a time interval. Changing this number alters the sharpness of focus. The default values are 3.5 for motor driven focus drives, and 3.75 for piezo driven focus drives. This setting compensates for time lags inherent to the video processing.

F= Switch Axis; if your focus controller can control two focus axes, e.g., a motorized drive and a piezo drive, then you may have the option to choose which axis to use for auto-focusing. Every axis that the focus controller controls is assigned a number starting from zero. Check with ASI to determine if this option is available for your system and to get the number for each axis.

Executing AFC alone will begin the Auto Calibration routine. Using AFC with arguments will only set or read back those parameters.

Response

:A or Error Reply

If the X, Y and F arguments are omitted, then an A is returned after the calibration is complete.

Example
AFC
:A<CR><LF>

AFC X=8 Y=3.75
:A

AFC X?
:X=8 A

AFC
Returns an :A after operation is complete, an :N-5 if the operation failed, or an :N-50 if the focus drive’s clutch is disengaged (if applicable).

Type Card-Addressed
Remembered Using [Addr#]SS Z
MS2000 and RM2000 Syntax
Shortcut AL
Format AL [X=Log_amp_AGC] [Y=LED_intesity_pot] [Z=in_focus_mm]
Remembered Using SS Z

X and Y arguments of this command to directly read and write values (0 to 255) to the CRISP electronics digital potentiometers. (Not recommended for use with host software.)

The Z-argument specifies the focus precision (in millimeters) when the lock state changes from K or k to F. Useful for automatic checking of desired focus stability. Also useful to enforce a tighter or looser focus state before indicating a lock condition. Note that this value is overwritten whenever the NA of the objective is specified via the LR Y command as of November 2015.

For Video Autofocus
Tiger Syntax

Format [Addr#]AL [X= x-axis highlight] [Y= y-axis highlight] [Z= safety limit enable]
Type Card-Addressed
Remembered Using [Addr#]SS Z
MS2000 and RM2000 Syntax
Shortcut AL
Format AL [X= x-axis highlight] [Y= y-axis highlight] [Z= safety limit enable]
Remembered Using SS Z

The X and Y values set the length and breadth of the Sampled/Highlighted Video area. Range is 0 to 100, with the value of 0 covering 0% of the video frame and 100 covering 90% of video frame.

The Z value enables or disables the 200 µm safety limit described in the AUTOFOCUS OPERATION section on page 4. Setting safety limit enable = 1 enables the safety limit; safety limit enable = 0 disables the safety feature. The default value is 1.

Caution: Disabling the safety limit could result in damage to your optics, your sample, or your focus drive.

Tiger Syntax
Shortcut AF
Format [Addr#] AFOCUS X= [% of speed] Y= [travel distance in mm] Z= [Hill Detect enable] F= [Hill Offset]
Type Card-Addressed
Remembered Using [Addr#]SS Z

The AFOCUS command will invoke an auto-focus routine using the speed and travel range specified by the previously set X and Y parameter settings. This routine can also be activated by pressing “@” button on most controllers. Entering AF without arguments will initiate the auto-focus routine itself, whereas issuing an AF with arguments will only set the parameters. An auto-focus scan can be canceled with HALT command or by issuing the \ shortcut. When an AF command is issued, the controller only replies after the operation is complete. It returns a :A[###] if the operation was successful, or N-5 if there was an error.

X= Speed. Range is 0 to 100 denoting the percentage of the focus drive’s maximum possible speed to travel during an auto-focus scan. This speed is also used by the AFCALIB (or AFC) command.

Y= Total scan range in millimeters. The focus controller moves down one-half this travel distance, and then scans up the full travel distance. This range is also used by AFCALIB (or AFC) command.

Z= Search type; either 0 or 1. A value of 0 enables Normal mode, while a 1 enables Hill Detect mode. (Z values 2 and 3 are reserved for future use.)

F= Hill Offset. Range is 0 to 100 denoting a percentage of a hill. If the Search Type is Hill Detect, then this setting determines when the scan will end. Once a hill peak is detected, the scan will terminate when past the peak by the Hill Offset percentage value.

Response

:A or Error Reply.

Example
AF

AF X=5 Y=0.1 Z=0
:A

AF X=10 Y=0.3 Z=1 F=10
:A

AF X=200 Z=2
:N-4

(Error indicates arguments out of range) 

AF X?
:X=10 A

AF
Returns :A [quality#] after operation is complete, an :N-5 if the operation failed, or an :N-50 if the focus drive’s clutch is disengaged (if applicable).

When all of the arguments are omitted, the A is transmitted after the focusing scan has completed. The number in brackets is the difference between focus value when in-focus compared to when out-of-focus. It indicates the quality of focus obtained.

Caution: To protect the optical assembly and sample, ensure that the sample is at least 200 µm away from the optics and that the current position is zeroed, that is, the LCD display shows Z: 0.00000> 0.00000 before sending the AF command to the controller (where Z is the focus axis).

Tiger MicroMirror Phototargeting
Shortcut IJ
Format [addr#]AIJ [X=horiz_position] [Y=vert_position]
Units axis units
Type Card-Addressed
Required Firmware Module MM_TARGET
Remembered Using [addr#]SS Z

Moves to the specified location (horiz_position, vert_position) subsequently pulses the laser TTL signal. Positions are specified in axis units (the same as used by the WHERE or MOVE command). If the X and/or Y argument is omitted, the corresponding position from the last AIJ command will be used. Note that the position is changed as a side effect of this command. The WHERE or MOVE command will change the beam position without pulsing the laser TTL signal.

The settling delay before turning on the laser and the laser pulse high time are specified using the WAIT and RTIME commands respectively.

The assignments of horizontal and vertical axes are done using the SCAN command (most users will never need to change the defaults: the horizontal or X axis is the card’s first axis and the vertical or Y axis is the card’s second axis).

Command:ARM

Shortcut ARM
Format ARM [X] [Y=log] [Z]
Remembered Using SS Z

Without arguments, this command establishes the ARM_COMMAND_RCVD event. Typically it is used to start the SEQUENCER via a single serial command.

ARM X re-initializes the SEQUENCER. This command is useful if the RESET conditions are changed or if the sequencer is hung in a non-IDLE state.

ARM Y=1 turns on or ARM Y=0 turns off the serial log file creation.

ARM Z forces a “sequence stop” condition. The sequencer is re-initialized; all blocks with ALWAYS start conditions are placed in the IDLE state, and all stage motion is halted.

Remembered Using SS Z
Tiger syntax
Shortcut AR
Format [addr#]AR [X=Nx] [Y=Ny] [Z=Δx] [F=Δy] [T=θ]
Units X and Y in integer, Z and F in mm, θ tilt degrees from X axis
Type Card-Addressed
Required Firmware Module ARRAY
Remembered Using [addr#]SS Z

The ARRAY command sets up a grid of points that can be traversed automatically with simple TTL control or with the RBMODE or AIJ commands. The size of the array is Nx by Ny points, with points spaced apart distance Δx and Δy (expressed in millimeters). The location of the first point in the array is set with the AHOME command. Small tilt corrections can be included using the T=tilt angle in degrees from the X-axis. The actual Δx and Δy for each move will be modified to account for the tilt angle.

Without arguments, the AR command starts self-scanning of the array. When the stage arrives on target, it will delay for a period of time set by the command RT Z=time_delay before continuing on to the next position. It is possible to repeat the array using the RM F byte.

Units millimeter
Remembered Using SS Z
Tiger syntax
Shortcut B
Format BACKLASH [axis] = [distance]…
Units millimeter
Type Axis-Specific
Remembered Using [addr#]SS Z

This command sets (or displays) the amount of distance in millimeters to travel to absorb the backlash in the axis' gearing. This backlash value works with an anti-backlash routine which ensures that the controller always approaches the final target from the same direction. A value of zero (0) disables the anti-backlash algorithm for that axis. Default depends on motor build but is 0.04 for most common 4 TPI leadscrew pitch, 0.01 for most common 16 TPI leadscrew pitch, and 0.02 for the x-axis of scan-optimized stages.

Example: 

B X=.05 Y=.05 Z=0 
:A
B x?
:X=0.040000 A

The command in this example will make the controller move the X and Y axes to a location 50 microns away from the final target before moving to the final target, while the anti-backlash algorithm for the Z axis is disabled.

MicroMirror and Tunable Lens Card
Shortcut B
Format B [axis]=[0.1 or 650] …
Units Frequency in kHZ
Type Axis-Specific
Remembered Using [addr#]SS Z

This command is “recycled” for a different use in MicroMirror axes than for motor axes. In the context of a MicroMirror axis this command is used to set the cut off frequency of the 5th order Bessel filter. Units are in KHz. The lowest acceptable value is 0.1 (100Hz) and highest is 650 (650kHz). For a typical micro-mirror to avoid mechanical resonance this should be set no higher than 0.8 kHz.
Example: 

B R=0.1 S=0.1 
:A

Sets 100Hz filter cut off freq for R and S axes 

B P? Q?		 
:P=0.4 B=0.4 A

Queries the filter cut off freq for P and Q axes

Type Card-Addressed
Firmware Version Required 3+
Remembered Using [addr#]SS Z

In Tiger version 3.0+ and MS2000 version 9.2g+ the Button Function assignment has been rewritten to be more flexible. Every possible button function is now assigned a number. This function can be assigned to any button (@,Home and Joystick Button) and any press duration (Normal, Long and Extra Long press) thru the BCA commands X,Y,Z,F,T,R and M arguments.

The settings of BCUSTOM are automatically saved in non-volatile memory when changed, they will be available even on controller restart.

As of Tiger version 3.18 and MS2000 version 9.2l a button function can be initiated over serial using the BE F command (BENABLE). The function doesn't need to be assigned to a particular button for this to work.

Note: Behavior of this command is very different pre Tiger version 3.0 and MS2000 version 9.2g

Press Dur:
* When button is held down for an instant to 1 sec, it's a Normal Press	
* When button is held down for 1sec to 3sec, it's a Long Press
* When button is held down for 3sec and more, it's an Extra Long Press

Example:

Take a firmware build like STD_XY . This firmware is packed with modules like,

  • Ring Buffer module
  • JS_FASTSLOW, joystick button press toggles joystick speed between fast slow.

In a built like this there are a lot of modules fighting for control of the buttons. There is a priority list that sets up the defaults button function . Lets Query the controller on what the default assignments ended up being.

Tiger Example
1BCA X? Y? Z? F? T? R? M?
X=0 Y=0 Z=0 F=0 T=0 R=28 M=18 
X: @ Normal 
Y: @ Long 
Z: @ Ext Long 
F: Home Long 
T: Home Ext Long 
R: Js btn Normal 
M: Js btn Long 
<LF>
MS2000 Example
BCA X? Y? Z? F? T? R? M?
X=0 Y=0 Z=0 F=0 T=0 R=28 M=18 
X: @ Normal 
Y: @ Long 
Z: @ Ext Long 
F: Home Long 
T: Home Ext Long 
R: Js btn Normal 
M: Js btn Long 
<LF>

So @ normal press, does nothing @ long press, does nothing @ extra long press, does nothing Home long press, does nothing Home extra long press, does nothing Joystick button normal press, toggles joystick speed Joystick button long press, loads current position into ring buffer.

If user wants the Ring Buffer to be more prominent, then following command can be issued.

Tiger Example
1BCA X=6 F=24 R=18 M=28
:A
<LF>
MS2000 Example
BCA X=6 F=24 R=18 M=28
:A
<LF>

Now, @ normal press, moves to next ring buffer position Home long press, clear the ring buffer Joystick button normal press, loads current stage position into ring buffer Joystick button long press, toggles joystick speed

A user with a Tiger system in the above configuration has two clocked position devices. A filter slider on card #2 and turret on card#3. They would like to move these devices with button presses. Lets set it up so that on short '@' button press (less than 1-sec press) Filter slider moves, then on long'@' button press (1 to 3-sec press) the turret moves. The button function that does this is '# 4' (see the table above). '@' short press assigned with 'X' variable, and '@' long press is assigned with 'Y' variable.

2BCA X=4 Y=0 , this tells card#2 which drives the filter slider to respond to short @ press with slider move, and ignore any long @ button presses.

3BCA X=0 Y=4 , this tells card#3 which drives the turret to respond to long @press with turret move and ignore any short @ button presses.

1BCA X=0 Y=0 , this tells card#1 which drives XY stage to ignore any short or long @ button presses.

Try it out. If you like the behavior, commit it to systems onboard memory with serial commands

Type Card-Addressed
Remembered Using [addr#]SS Z

Enables or disables button functions for the specified card and specified buttons, either all/none (X, or Toggle) or with finer granularity (Z, or Enable_byte). Toggle=0 disables all buttons and pulses; i.e. BE X=0 is equivalent to BE Z=0. Toggle=1 enables all buttons and pulses (default settings); i.e. BE X=1 is equivalent to BE Z=15. Querying X returns the same as querying Z. Specific buttons can be enabled/disabled by explicitly setting the Enable_Byte. The bits are set to one 1 when enabled or zero 0 when disabled, and are defined as follows:

Z parameter Enable_Byte is bit-mapped number that determines which buttons are enabled or disabled as tabulated below. Bit5 is a special case; it changes the behavior of the physical button to zero the Z axis only and has been removed from Tiger code after v3.20.

Bit# Button
0 “Zero” Button
1 “Home” Button
2 “@” Button
3 Joystick Button
4 Reserved
5 Zero Z Only (removed from Tiger after v3.20)
6 Reserved
7 Reserved

F parameter Button_Function is a positive integer code for the button function that will be executed. See documentation of BCUSTOM for a list of available button functions. This allows a button press to be simulated using a serial command. This is available from Tiger v3.19 onward and in middle of Whizkid v9.2l.

Tiger Example

Additional Feature in Tiger Version 3.14+
Addressing the COMM card specifically (or omitting the address on the command) results in a different behavior. Disabling a button on the COMM card will result in disabling that functionality for all cards in the rack. This disabling happens at the COMM card so the other cards in the rack never receive notification of a change in the button's state. In this way, individual cards may be set to the desired functionality and a layer of control over all cards may be applied without affecting the settings on individual cards.

The 0BE Y? query command provides a report of past button states. Every time one of the inputs is activated, the COMM card notes the activation by setting a bit in a status byte. That bit will remain set until the status byte is queried again on the COMM card with 0BE Y?. The result of the query will return the current status byte to the host, then clear the status byte (set all bits representing input sources to 0), thereby preparing the status byte for further button press detection. The format of the bits in the returned status byte is the same as the table above. A one 1 on the specified bit represents the input has been activated since the last query.

Starting with v3.21, a button that is held down during a serial query of button state will be reported as activated every query up through the one immediately following release. This can be used by high-level software to time button presses, e.g. if querying happens every second and the button is held down for 1.001 seconds then it will be reported as being held down twice. If the button is held down for 0.1 seconds then most of the time it will only be reported once, unless the query happens to occur during that 0.1 seconds in which case it will be reported twice.

As no address was given, Tiger Comm replies. It replies with its build name, all axis names present in the system (axes will always be A-Z, filterwheels 0-9). For each axis the type is given (see table in section “Identifying Controller Configuration”) and the card address in both character and hex formats. Finally, an integer is given to indicate the presence of special properties or capabilities of the axis, such as CRISP auto-focus or RING BUFFER module for TTL positioning; these can be interpreted using the information below. This command is useful to quickly identify all the axes names and types present in the system.

Units Unitless float between 0 and 1
Type Axis-Specific
Remembered Using [addr#]SS Z

This command is “recycled” for a different use in MicroMirror axes than for motor axes. For MicroMirror axes it sets up a calibration constant or scale factor that is used to attenuate the scanner motion when used in internal input mode (as the implementation is in software it does not apply in external input mode). In tests we found that the two axis of the MEMS MicroMirror does not tilt by the same amount when similar inputs are applied. This may be critical for some applications. This parameter sets an attenuation, so both axes can be made to tilt the same amount. For example, if the S axis was found to be doing 85% travel of R axis then we could attenuate R to compensate by setting D R=0.85 S=1. Note that behavior is undefined if changed in the middle of a single-axis move or SPIM move on the same axis. N.B: This command was retired in v3.14 of the firmware because it wasn't being used and the internal implementation was complex.

Example: 

D R=0.85 S=1
:A

Attenuates the travels of R axis by 15%.

Dump internal buffers to terminal screen.

The Tiger and MS-2000 controller has several built-in diagnostic capabilities that are useful for troubleshooting difficulties and for tuning the servo motion parameters. It is often useful to see how well the servo motion is tracking the theoretical trajectory. The controller has a built-in buffer that can hold 200 to 500 move steps. For best results, restrict testing to a single axis at a time; otherwise information from multiple axes will be interleaved in the dump buffer. Any motion from any axis will write information into the dump buffer until it is full.

DU, without arguments, dumps the Trajectory Buffer.

DU X clears Trajectory Buffer.

DU Y dumps Error Buffer. See Error Codes for MS2000,RM2000 and TG-1000 Diagnostics

DU F Prints controller log, it has information like total time controller was ON, Total distance XY stage travelled and others. The log first has to be initialized with command DU F=999 . This is done in the factory, and we suggest users not reset the log as it may wipe data that is useful for ASIs long term reliability study.

DU R=mode sets the trajectory buffer mode (introduced in Tiger v3.19). Mode 0 (default) means the trajectory buffer, once full, will not be changed further. Mode 1 continuously overwrites the trajectory buffer information so that the most recent move information is always present.

DU T=interval sets the sampling interval for the trajectory buffer (introduced in Tiger v3.19). Default is 1 which adds to the trajectory buffer on every axis loop. Setting to e.g. 10 will add to the buffer once and then skip the next 9 axis loops. Handy for looking at longer-term trends.

Tiger Example
1DU X Clears the dump buffers on card#1
Then make a short move, e.g.: M X=12345 [Moves about 1.23 mm] After the move is complete, you can dump the buffer to the screen: 1DU Dumps Trajectory Buffer on card #1

This command lets the user set a position, in millimeters - absolute, which will toggle a TTL output when the stage crosses that position. When ENSYNC is issued, the TTL output is reset low. Whenever the stage crosses the ENSYNC position, the output will toggle low to high and if crossed again, from high to low. ENSYNC will only work with one axis at a time, either X or Y and depends on how JP1 is jumped.

On MS2000

(JP1-1&2 = X axis, JP1 – 2&3 = Y axis) The TTL output is available on pin SV1-7. Contact ASI for additional details on these modifications

On Tiger

Need Dual Axis card Rev F3 and above. Pin is routed to the backplane. Additional hardware is needed to expose the signal. Contact ASI for additional details on these modifications

Format ERROR [axis]=[position in mm]…

Type Axis-Specific
Remembered Using [addr#]SS Z

This command sets the Drift Error setting. This setting controls the crossover position error (in millimeters) between the target and position at which the MS 2000 and TG-1000 controller considers an axis to be too far out of position. When this limit is reached, the controller will re-attempt to move the axis back within the Finish Error (PC) limit. The current value for this setting can be viewed using the INFO command or by placing a ? after the axis name. Entries of zero value, e.g., ERROR X=0 are ignored.

Example 

E X=.0004
:A
e x?
:X=0.000400 A

Input values equal to or less than zero are acknowledged by :A , but ignored.

The command in this example would cause the controller to consider a difference between the target and the current position greater than 400nm to be too large. If this large of an error were detected, the controller would re-engage the move algorithm to place the position error back inside of the Finish Error (PC) limit.

Format ERROR [axis]=[correction in %]…
Units integer code
Type Axis-Specific
Remembered Using [addr#]SS Z

On a Micromirror card ERROR command has a different purpose and function. It sets the amount of bow correction applied to the axis. It is specified in units of percent deflection of the paired axis when the specified axis is at full deflection. The sign indicates whether a positive or negative deflection will be applied to the paired axis. It was introduced in Tiger firmware v3.18 along with the bow correction described below.

Bow is an optical effect where the motion of a scanned beam takes on a slightly curved shape whenever the axis of the moving mirror's rotation is not orthogonal to the plane formed by input and output beams. Because the MEMS mirror inside the ASI scanner tilts in two dimensions, at least one axis will be subject to this effect. In a typical ASI light sheet scanner, the motion of the “fast axis” (e.g. the axis that is scanned to make a light sheet) will deflect slightly in the slow axis during scanning, whereas the motion of the slow axis is unaffected by the bow phenomenon. To counteract this optical effect, starting in firmware v3.18 the firmware applies a small opposite correction to the slow axis as the fast axis moves, and the magnitude of this correction is specified by the ERROR command. The correction is quadratic relative to the displacement from the center of the mirror range (generally position 0), so maximum correction is applied at the edge of the mirror range.

The default is -2% for the “fast axis” and 0.0 for the “slow axis” in each axis pair because this seems to be about right for a typical ASI scanner. This means that the slow axis position will be adjusted as the fast axis moves but not vice versa. The bow correction is applied during regular commanded moves, during single axis commands, and during the SPIM state machine. In the SPIM state machine it is assumed that only the fast axis has a non-zero bow correction coefficient.

The allowable range of correction is between -6.22% to +6.22%.

This command will stop all active motors and other actuators too. If there are no errors, a positive reply of :A will be returned. If the HALT command is given while a commanded move is in motion, the controller will reply with the :N-21 error.

Additional Notes regarding usage on Tiger
It’s usually a Broadcast command but can be used as a Card-Addressed Command as well. When addressed to a specific card, it stops motion on that card only. Note that to use as a Card-Addressed Command the full command HALT must be used instead of the shortcut \, because \ is handled quickly in the command parser.

Assign the specified number to the axis’s current position buffer. If no position is specified, 0 is assumed. The unit of measurement is in tenths of microns. This defines the current position to be a specific distance from the origin (0), i.e., the origin may change.

On clocked devices (filter slider, turret etc) use the + (plus) operator to sets the spacing of the nth position. Example, On a 2 position objective slider, if the user wants to adjust the spacing of the 2nd objective so that it's better aligned to the optical path, they can adjust 2nd objectives position with a manual input device, then save it by issuing serial command H [Axis char]+ . Only available on MS2000 version 9.2m and above, TG1000 version 3.28 and above.

If there are no errors, the positive reply :A will be sent back from the controller

DOES NOT WORK FOR PIEZOS AND MICROMIRRORS. DOES NOT WORK FOR “CLOCKED DEVICES” SUCH AS FILTER SLIDERS AND TURRETS.

Example

This command sets the relative motor speed for maximum deflection of the joystick to the values specified. Values between 0.1 and 100 (%) are acceptable, or -100 to -0.1 (negative setting reverses the direction). Pressing the Joystick button toggles between the high and low settings.

Knob_speed is a signed value that sets the relative speed and direction of the encoder knob (not commonly used on TG-1000).

xy_knobs_high and xy_knobs_low are used to set the fast and slow speeds for XY_KNOBS and ZF_KNOB, which respond to input from the two knobs on the side of the TG-1000 joystick. Note this is different from MS-2000 where the F parameter set the low speed and the high speed was given by the low speed multiplied by the T parameter raised to the third power. Note that prior to stage firmware version 2.87 the implementation for F and T was like MS-2000.

If there are no errors, the positive reply :A will be sent back from the controller.

Enable out from the LED illuminator should be connected to TTL out on controller. This setting can be saved in non-volatile memory using the SAVESET command. The PWM frequency is 1.3KHz. It’s a Card-Addressed command.

Type Percentage between 0 and 100
Remembered Using [Addr#]SS Z

This command is “recycled” for a slightly different use in TGLED than for other cards . In the context of a TGLED card this command is used to set the individual brightness percentage of the LEDs connected to the card. Setting the brightness to 0% results in LED to be off. Setting the brightness to 50% results the in the LED being driven with PWM with 50% duty cycle. Setting the percentage to be 100% results in the LEDs to turn on fully.

X sets the brightness for LED connected to channel 1, Y sets the brightness for LED connected to channel 2, Z sets the brightness for LED connected to channel 3, and F sets the brightness for LED connected to channel 4.

Default is 50.

Example 

1LED X=10 Y=50 F=0

Remembered Using [Addr#]SS Z
Firmware Required MM_LASER_TTL

The LED commands are used to control the laser outputs of the card (Micro-mirror card backplane connectors, usually output by the Programmable Logic Card or TTL card in early versions). The origin of these commands was for MM_SPIM firmware, but a separate define MM_LASER_TTL was created so that it could be used in other situations as well. This documentation for v2.88+, though the Y parameter was added ~v2.86. In general these only apply when the auxiliary TTL output mode is set to 1 (TTL T) and when the SPIM state machine is not running.

output (X) selects which logical laser is on when the SPIM state machine is not running. The exact hardware output depends on bits 0-2 of the LED Z setting. X=0 means neither laser is on, X=1 means the Side0 laser is on, X=2 means the Side1 laser is on, and X=3 means both lasers are on (LED Y setting applies in this case). Requires TTL T (aux_IO_mode) setting to be 1. Setting is overridden during SPIM state machine operation.

switch_time (Y) sets the switching time in ms between the laser outputs when the SPIM state machine is not running and when both lasers are active per the LED X command. Used to simulate the effect of a passive 50/50 beam splitter, which is particularly useful during alignment. Default is 10ms, cannot be set less than 1ms.

laser_mode (Z) determines the behavior of the laser TTL outputs, both when using the LED settings and also during the SPIM state machine.

  • Bits 0-2 form a code 0-7 selecting how the logical laser outputs are converted to physical TTL outputs. Setting should correspond to the physical hardware connected to the laser TTL outputs. Specifically
    • code 0 for individual laser shutters for the two sides (default until v3.01)
    • code 1 for single laser with side switch (Side0 is laser shutter for both sides and Side1 is high when the second side is active) (default v3.01+)
    • code 2 for Side0 high when the first side of SPIM is active, Side1 high when the second side of SPIM is active
    • code 3 for single laser (Side0) automatically turned on during a FAST_CIRCLES move
    • codes 4-7 are reserved for future use
  • Bits 3-7 are reserved for future use and currently cannot be set

Side0_state (R) can be set to 1 or 0 as shorthand for turning on/off the Side0 laser without affecting the state of the Side1 laser. It is equivalent to querying the logical laser output state (X), changing the LSB, and then setting the output state (X). Introduced in v3.11.

Side1_state (T) can be set to 1 or 0 as shorthand for turning on/off the Side1 laser without affecting the state of the Side0 laser. It is equivalent to querying the logical laser output state (X), changing the 2nd bit, and then setting the output state (X). Introduced in v3.11.

Firmware Required DUAL_LED

Dual LED is a new two LED driver for MS2000. Instead of using PWM to dim the LED, DUAL LED varies the current applied to dim the LEDs resulting in very little flicker even at high shutter speeds. The brightness of the two LEDs can be independently set using the X and Y arguments of the LED command. At 100% brightness about 900ma is applied. Dual LED have a current limiting feature, user can set the maximum allowed brightness of the two LEDs with R and T arguments. This setting is saved in a non volatile memory on the PCB , so this setting is preserved even after firmware upgrade. Say a LED with maximum rated current is 100ma attached to channel 1. Then setting LED R=10 will limit the maximum applied current to 90ma.

X sets the brightness for LED connected to channel 1,
Y sets the brightness for LED connected to channel 2,
R sets the maximum brightness for LED connected to channel 1, and
T sets the maximum brightness for LED connected to channel 2.

Example 

LED X=10 Y=50
:A

Sets the Brightness of LED connected to Channel #1 to be 10% , Channel #2 to be 50% . 

LED X? Y?

Firmware Module Required RING BUFFER

The LOAD function places a set of position coordinates in the next available internal ring-buffer memory location. The position values are expressed as floating point numbers representing tenths of a micron, the same as the MOVE command. If a + is specified instead of =###, then the current position of the axis is stored in the ring buffer (as of Tiger firmware v2.81 and MS2000 firmware v9.2g). For example, the command LOAD X+ Y+ Z=0.1 would store the current position of the X and Y axes and the Z position of 10nm to the ring buffer. The ring buffer contains 50 positions by default; contact ASI for the option of having 250 positions in the ring buffer (but this entails certain tradeoffs).

The coordinates for the next move may be queried by using the command LD X? Y? Z?. Setting the current buffer position and initiating moves to locations stored in the buffer can be done using the RBMODE command (see below), or by using a front panel button. The LOAD operation increments the number-of-positions counter accessed using RM X? (see the RBMODE command). In TG-1000 the ring-buffer is stored and executed on a per-card basis. If positions for one or more axes on one card are specified but others are not, the position of the unspecified axes during the ring buffer execution will not be well-defined. To clear the buffer, type RM X=0.

The current stage position (for all axes with RING_BUFFER firmware) may be loaded into the ring-buffer by pressing the Joystick button for 3 seconds and releasing.

CAUTION: If you are using TTL mode 12 (see the TTL command), the values entered into the ring buffer using the LOAD command represent RELATIVE coordinates, not ABSOLUTE coordinates. You must drive the stage to the appropriate starting position before triggering any ring buffer sequence.

Shortcut LK
Format LK [X] [Y] [Z=lock_offset] [F=code]
Remembered Using SS Z

The LOCK command without any arguments X, Y, or Z advances to the next system state just as would a short-press of the @ button.

LK X? returns the single character indicating the current CRISP system state as described in the table CRISP System States. For historical reasons, do not use LK X to set the current state, instead use LK F.

LK Y? returns the present value of the focus error which is also shown on the LCD display.

LK Z? returns the present value of the focus error lock_offset. The offset is automatically determined during calibration and is modified when the command wheel on the controller is used to focus a locked system. The offset is also reset with a >10 sec. press of the @ button. A particular value of lock_offset may be set using LK Z= lock_offset.

LK F=code will unconditionally set the focus state. Code is the ASCII decimal equivalent for the ‘state’ character that is displayed on the LCD. For example, to unconditionally enter the ‘B’ state the command would be LK F=66. Not all states are best entered directly. See the CRISP system state table for the appropriate ASCII code to enter a particular state gracefully.

Type Card-Addressed
Remembered Using [Addr#]SS Z

The LOCK command without any arguments toggles the SERVOLOCK_TTL function from active to inactive. As short-press of the @ button will also do unless the firmware build also has CRISP, in which case CRISP takes priority. See full documentation of SERVOLOCK_TTL firmware module.

LK X? returns the single character indicating the current state, which for SERVOLOCK_TTL is the letter T for enabled and Z for disabled. If CRISP is also present in the firmware module then those states will also appear. LK F=code will unconditionally set the focus state. Use LK F=84 (ASCII letter T) to enable SERVOLOCK_TTL control and LK F=90 (ASCII letter Z) to disable it when done

TGPMT usage

Type Card-Addressed
Remembered Using [Addr#]SS Z

This command has a different function on a TGPMT card. Here its used to check the status of PMT (overloaded or not). Then if it is overloaded, issue a reset pulse to clear the overload. Duration of the reset pulse is set with the RT Y command

[addr#] LK X? , Query PMT0's status. Controller return a 0 if Overloaded , and 1 if not overloaded.

[addr#] LK Y? , Query PMT1's status. Controller return a 0 if Overloaded , and 1 if not overloaded.

[addr#] LK X , Issue a reset pulse to PMT0.

[addr#] LK Y , Issue a reset pulse to PMT1.

Alternately , the status of the PMTs is also indicated by the LEDs on the TGPMT card (Green is ok , Red is overloaded). And the reset button can be pressed to clear the overload state.

Example 

7lock x?
:A 0

Query the status of PMT0 on TGPMT card at address 7 for status. 0 is returned, indication PMT0 is overloaded 

7lock x
:A

Issue reset pulse to PMT0 on TGPMT card at address 7. 

7lock x?
:A 1

Overloaded was cleared, Query the status of PMT0 on TGPMT card at address 7 for status again. 1 is returned, indication PMT0 is NOT overloaded

LK with no argument performs same action as “@” short press.

LK X performs same action as “@” long press.

LK Y performs same action as “HOME” very long press.

Use sum_min to set the minimum sum-signal level required for tracking the sample. If the sum signal is less than sum_min, tracking will PAUSE.

The quad_order is the relative orientation of the PMT assembly and is normally set during calibration.

Shortcut LR
Format LR [X=cal_gain] [Y= objective lens NA] [Z=lock_range] [F=cal_range] [T=loop_gain]
Remembered Using SS Z

The LOCKRG command allows the user to control of several system variables. The X parameter, cal_gain, is the gain variable normally obtained from running the calibration sequence. Although not recommended, it can be changed with this command, but it will be reset upon running the calibration sequence.

The Y parameter sets both the cal_range focus depth (LR F) and also the in_focus_mm range (AFLIM Z) appropriately for the specified numerical aperture of the objective. The computed values can be read and/or overridden using the LR F and AFLIM Z commands respectively.

The Z parameter controls the maximum excursion of the stage before the system generates an error condition and unlocks. The value lock_range is in units of millimeters. The default value is 1.0 mm.

The F parameter controls the excursion of the stage when going through the calibration sequence. The default value for cal_range is 0.005 mm. Overridden when the objective’s NA is set using LR Y.

The T parameter controls the gain multiplier or loop gain also set by KADC command. This is for convenience only, both have the identical effect. In this case the axis character does not need to be specified.

With SERVOLOCK_TTL
Tiger Syntax
Shortcut LR
Format [Addr#]LR [Z=lock_range]
Type Card-Addressed
Remembered Using [Addr#]SS Z

The SERVOLOCK_TTL module uses the LOCKRG Z command to set the maximum excursion. If CRISP is also present then the same setting is shared by both modules.

The Z parameter controls the maximum excursion of the stage from the position where it was initially locked before the system generates an error condition and unlocks. The value lock_range is in units of millimeters. The default value is 1.0 mm.

On Phototrack system
Shortcut LR
Format LR [X=cal_value] [Y=xy_lock_range] [Z=z_ lock_range] [F=cal_range]
Remembered Using SS Z

This command sets range limits for tracking and autofocus systems. For XY tracking systems, the excursion from the point of lock for both the X and Y axes in millimeters is set with the lock_range value using the Y parameter. If the system encounters a lock_range or focus_range limit, servo tracking is terminated.

Cal_range is the distance in millimeters of the stage movement for automatic calibration of the Tracking or Focus system, set using the F parameter. The result of such a calibration is the cal_value, which can be set explicitly with the X parameter or queried using LR X?. The tracking parameters can be displayed on the serial terminal using LR Z.

Query: LR X? Y? F? returns the current value of the parameters.

Function for Motorised Actuator (xy stage, z drive etc)
The maintain command specifies the behavior of the controller after move completion. Move commands complete when the stage moves to within the finish error tolerance of the target position (PCROS command). The actions for various code values are:
code = 0 [default] Post-move, when the controller detects drift from target specified by the drift error value, it will return the stage axis to the target several times (18) within a timeout period (~0.5 sec.) before declaring a move error code 60 and giving up further attempts.
code = 1 Post-move, the controller will indefinitely continue to try to reach target when drifts greater than the drift error are detected. With codes 0 and 1, the motor drivers are turned off when the stage reaches the finish error tolerance.
code = 2 The motor drivers remain on and the servo loop remains active. NB: making a manual move (e.g. joystick) may turn the motors off.
code = 3 Drivers remain on and servos active for the post-move time set by the WAIT command. The system BUSY is released when the finish error tolerance is first achieved. Setting the WAIT time sufficiently long can stabilize post-move drifts during data recording, but then allow for less power consumption of the driver amplifiers when waiting between moves.
code = 4 Reserved
code = 5 Servos Disengage. For example with motorized turrets this will allow the user to manually move the turret.

If there are no errors, the positive reply :A will be sent back from the controller.

Function for Piezo actuator

This feature is only available on Tiger system

This command is “recycled” for a different use in piezo axes than for motor axes. For ADEPT piezo cards sets the maintain code. Currently 2 modes are implemented with the following codes:

MA [axis] = Mode
0 default
1 Overshoot algorithm

Mode 0 is the default where the piezo DAC is set and the piezo drive electronics apply a voltage to the piezo to move the piezo to the correct position as measured by the strain gauge.

Mode 1 is the overshoot algorithm which may reduce the setting time in many circumstances where speed is critical and the user is willing to do some tuning. The piezo DAC is set as if the move were traveling past the actual target according to an overshoot percentage set by the PZ T setting. The idea is to slew more quickly initially. When an exit condition is reached the piezo DAC is set to the desired final position. There are two exit conditions, meeting either one or the other is sufficient:
(1) the strain gauge indicates that the piezo is at least halfway to the final position or
(2) the maximum time for the overshoot to be applied set by the PZ R is reached.

Note: At one point this behavior was controlled using the PM command. It was shifted over to MA starting in v3.06 but not in its current form until v3.11. Using this anything besides the default setting with firmware between v3.06 and v3.10 is not recommended.

This command enables + or disables - the controller’s ability to control the motor of a certain axis. The motor control voltage is set to zero and the position feedback control is not monitored when the motor is in disable - mode. The electronics of the controller will attempt to keep the motor from moving while disabled, however, it should be noted that this is an open-loop brake control only, and any movement or drift is not corrected. When queried, the controller returns values of 1 or 0 representing enabled and disabled respectively.

If there are no errors, the positive reply :A will be sent back from the controller.

Shortcut M
Format MOVE [Axis]=[units 1/10 microns]…
Units 1/10 microns
Type Axis-Specific

Move one or more axis motors to an absolute position. The unit of measurement is in tenths of microns. If no position is specified, 0 (the origin) is assumed.

For devices with CLOCKED POSITIONS (turrets and filter wheels), the position is an integer value between one and the number-of-positions.

A positive reply of :A is sent back when the command is received correctly. Reception of the reply does not mean the end of execution, and the command STATUS can be used to determine if the move has been completed.

Example
M X=1234 Y=4321 Z
:A

The controller will move the X-axis to position 123.4 microns from the origin using the maximum set speed (see SPEED). Simultaneously, it will move the Y-axis to position 432.1 microns, and the Z-axis to the zero (0) position.

During this movement, the Joystick and Encoder inputs will be locked-out and cannot alter the target positions entered. The motors will stop when they have reached their target or when their limit switch is encountered. To stop the motors during a serial MOVE command, use the HALT ( \ ) command.

Move one or more axis motor a distance relative from its current position. This command is very similar to the MOVE command. The unit of measurement is also in tenths of microns.

A positive reply of :A is sent back when the command is received correctly. Reception of the reply does not mean the end of execution, and the command STATUS can be used to determine if the move has been completed.

Example
R X=1234 Y=-321 Z

The controller will move the X-axis an additional 123.4 microns in the positive direction at the maximum set speed (see SPEED). Simultaneously, the Y-axis will move 32.1 microns in the negative direction, while the Z-axis will not move at all.

During this movement, the Joystick and Encoder input will be locked-out and cannot alter the target positions entered. The motors will stop when they have reached their target, or if their limit switch is encountered. To stop the motors during a serial MOVREL command, use the HALT ( \ ) command.

Format [addr#]MM [X=radius] [Y= speed] [Z= width] [F=mode_byte] [R?]
Type Axis-Specific
Remembered Using [addr#]SS Z
Firmware Module Required MULTIAXIS_FUNCTION

The MULTIMV command allows several common multi-axis move patterns to be executed. Presently the patterns supported include circles and spirals. If users have other special requirements, they should contact ASI for assistance.

The command, without any arguments, initiates the multi-axis pattern move. Commanded and manual (joystick) moves are not allowed while a multi-axis move is occuring.

The patterns are initiated from the current stage position. The movement is parameterized in terms of the speed (feed rate) in mm/sec and pattern parameters. For circles, the radius in millimeters is the only required parameter. For spirals the width per spiral turn in millimeters is required as well as the maximum radius.

The mode is a bit-mapped character that determines the characteristics of the motion. The mode bits are used according to the following table.

Bit Set Clear
0 Lead-in Move Used No Lead-in Move
1 Controlled acceleration along path, set by ACCEL command, to programmed speed. No controlled acceleration
2 Move pattern repeated indefinitely Only single cycle of move pattern executed
3 Reserved
4 Reserved
5 Reserved
6 Motion pattern selector bits 6 & 7:
00 FAST_CIRCLES
01 Circle
10 Helix
11 Spiral
7

This above settings can be saved into non-volatile memory by issuing the SAVESET command.

Specifying an argument for the pseudoaxis R in decimal sets the state directly (see table below; the value is simply the decimal representation of the corresponding state character). Note that the firmware expects only certain states to be set by the user (marked as “OK to set” in the table); setting to a different state may yield unpredictable results. Querying the pseudoaxis R value returns the decimal associated with the current state (currently expressed as a float; discard anything after the decimal).

Multi-axis move states (MULTIAXIS_FUNCTION firmware)
Char Dec OK to set? State
I 73 No Idle/disabled
S 83 Yes Starts state machine
P 80 Yes Stop (goes to idle state after cleanup)
L 76 No Lead-in move
A 65 No Accelerating
M 77 No Main move
m 109 No Back move (unused?)
F 70 No Fast circle move
R 82 Yes Restart move (fast circles only)
FAST_CIRCLES

In FAST_CIRCLES mode, a lookup table is generated internally so the circles can occur very fast assuming the hardware allows fast motion. Using this mode changes the behavior of some parameters. There is no way for the user to enable or disable the FAST_CIRCLES modifications; the firmware build either includes FAST_CIRCLES or not (tell by using the BUILD X command).

X parameter (radius) remains the same. Note that the units are millimeters (or degrees for micro-mirror).

Y parameter (speed) is now specified in circles per second. Valid values range from 2 to 1000 with a default of 100 (equivalently a 10 ms period). Most hardware cannot support speeds faster than a few hundred cycles per second.

Z parameter is now the asymmetry ratio. If set to 1.0 (the default) a perfect circle will be generated, if set to 2.0 then the Y axis will move twice as far as the X axis to form an ellipse with major axis twice that of the minor axis. At present there is no way to tilt the ellipse (e.g. phase) but this can be added if needed.

In FAST_CIRCLES mode the circle is repeated indefinitely regardless of Bit2 of the mode_byte.

In FAST_CIRCLES mode the circle is centered at the position whenever it was initiated. To change the offset of the circle, stop the multi-axis move if needed, move to the desired center, and initiate the move (again). (Commanded and manual (joystick) moves are not allowed during any multi-axis moves.)

Changes to settings during a fast circles move will not take effect until the fast circles move is re-initiated.

During a fast circles move the position reported by the WHERE command is the center of the circle, not the instantaneous position.

Circles

Lead-in move assumes start location is center of circle and moves out to \begin{equation}X → X + r\end{equation} before the circular motion is started.

Spirals

Spirals start at current location. Presently, no lead-in move is programmed. The spiral equation is \begin{equation}r = width × \frac{θ}{2π}\end{equation}. Motion continues to the maximum radius. If mode BIT2 is set, the motion then continues spiraling inward, and continues inward and outward until halted.

Example
3MM x=0.02 y=5 z=0.02 f=68
:A

This command sets up the parameters to do a circle pattern for axes on card with address 3 (for MS-2000 omit the initial character 3)

:A

This command sets up the parameters to do a spiral pattern for axes on card with address 3 (for MS-2000 omit the initial character 3)

This command sets (or displays) the amount of distance in millimeters to travel to absorb the backlash in the axis' gearing. Analogous to backlash, but will always overshoot the desired position by the set amount and then come back towards the move's origination, whereas backlash always approaches from the same direction. Backlash move, if any, occurs before the overshoot move. Default is 0, which turns the overshoot routines off. When queried will return the actual value instead of the user-set target value

Example: 

OS X=.05 Y=0
:A
OS x?
:X=0.049981 A

This command sets/displays the Finish Error setting, which controls when the motor algorithm routines will turn off. The setting controls the crossover position error (in millimeters) between the target and position at which the MFC 2000 and TG-1000 AND MS 2000 controller will stop attempting to move the stage closer to achieving the position=target. This is value also determines the maximum error allowable before a move is considered complete. This value is usually set to the value of the smallest move step size according to the encoder resolution. The current value for this setting can be viewed using the INFO command.

Example
PC X=.00005 Y=.00002 Z=.00005 
:A

Values equal to or less than zero are acknowledged by :A , but ignored.

The command in this example will make the controller consider a MOVE command complete when the difference between the target and the current position is 50 nm for X, 20 nm for Y, and 50 nm for Z.

This command is “recycled” for a different use in MicroMirror axes than for piezo. In the context of a MicroMirror axis this command is used to put the axis in internal or external mode.

1 is external input mode. Mirror is positioned based on analog input voltage. Default mode until v3.10, except for SPIM-enabled systems.

0 is internal input mode. Mirror can be positioned thru serial command or onboard routines. Default mode for SPIM-enabled systems and v3.10+.

Queries the mode of axes

Piezo
Shortcut PM
Format PM [axis]=[0 to 3,+,-]
Units Integer code, 0 to 3 and + and - sign
Type Axis-Specific
Remembered Using [addr#]SS Z

PM command sets the ADEPT card in various modes, Open Loop, Closed loop, MS2000 input and External input.

PM [axis] = Mode of Operation
0 TG-1000 input, Closed loop (default)
1 External input, Closed Loop
2 TG-1000 input, Open loop
3 External input, open loop
PM [axis]+ Fast Mode
PM [axis]- Slow Mode

In Open Loop mode, a set voltage is applied to the piezo and the feedback from strain gauge is ignored. Useful during system calibration.

In Closed Loop mode, the voltage applied to the piezo is adjusted according to the feedback coming from the strain gauges. This is the default mode of operation.

TG-1000 input, in this mode the TG-1000 controller generates the positioning input for the piezo top-plate. This is the default mode of operation.

In External input mode, the piezo top-plate is positioned according to 0 to 10V analog signal provided by the user. Every one volt change moves the piezo 1/10 the range. We recommend that frequency of the signal be kept less than 10Hz for long moves, to give the piezo top-plate sufficient time to settle and come to a complete stop.

PM [axis]+ : Requires v3.10+ firmware and Rev M5 or later ADEPT card. Switches in a faster more responsive piezo position controller. However it is less stable and prone to oscillation. Suitable for 150um piezos.

PM [axis]- : Requires v3.10+ firmware and Rev M5 or later ADEPT card. Switches in a slower but more stable piezo position controller. Ideal for 300um or 500um piezos and when using heavier payload or samples.

The modes will revert back to default state, i.e. TG-1000 input with Closed Loop when system is powered off. Use the [#Addr]ss z command to save your preference.

The settings set with this command can also be done with PZ commands. One does not have an advantage over another; usage is left to user preference.

The X argument sets the zero adjust potentiometer of the ADEPT card.The setting is stored in a non volatile memory on the ADEPT board. This is one of the settings that are automatically picked during both long and short auto calibration. Please refer the calibration section for its usage. On Tiger controller PSG command is equivalent. One does not have an advantage over another; usage is left to user preference.

The Y argument sets the gain of the feedback stage. The setting is stored in a non volatile memory on the ADEPT board. This is one of the settings that is automatically picked during long auto calibration. Please refer the calibration section for its usage. Pre MS2000 v9.2f and Tiger v2.83 a formula was used to convert 25-5101 to 8 bit 255. We had rounding off issues and such. We removed the formula so now user can enter the setting directly and thus have more control.On Tiger PG command is equivalent. One does not have an advantage over another; usage is left to user preference.

The Z argument sets the board in various modes. On Tiger controller PM command is equivalent. One does not have an advantage over another; usage is left to user preference.

PZ Z = Mode of Operation
0 Controller controlled, Closed loop (default)
1 External input, Closed Loop
2 Controller controlled, Open loop
3 External input, open loop
PZ Z+ Fast Mode
PZ Z- Slow Mode

The F argument (requires Tiger v3.11+ and MS2000 v9.2f) sets the value of the timer for Auto Sleep feature. Units of are in minutes. To maximize piezo actuators’ lifetime they should to be turned off when not in use. Every time the piezo is moved (e.g. commanded move, TTL-triggered move, or with a manual input device like the wheel) the auto sleep timer is reset to 0. When the timer reaches the value set by the F argument the sleep state is entered. In the sleep state piezos are moved to the sleep position and the code returned by the RS+ command (equivalent to the right status character on MS-2000 LCD screens) changes to E. However, the position returned by the WHERE command is not changed during sleep. Further, any move will proceed from the pre-sleep position. To disable the auto sleep feature, set the F argument to 0. On most firmware builds the default value is 0, i.e. disabled. However on SPIM builds the default value is 5 minutes. To exit sleep without affecting anything else, send the R <axis> command to execute a relative move of distance 0. Setting the F argument clears the timer but does not exit the sleep state.

Additional Tiger Only function
The R argument only applies when the piezo maintain code is set to 1. (In firmware between v2.83 and v3.10 it was the F argument instead.) It sets the maximum time to move towards the overshoot position, expressed in milliseconds. Refer to the documentation under MA.

The T argument only applies when the piezo maintain code is set to 1. It sets the overshoot amount, expressed as a percentage. For example, when set to 100 the piezo will begin the move as if the target position is twice as far away as it really is. Refer to the documentation under MA.

PZC when entered alone runs the auto calibration routine that sets various internal parameters for optimal operation of the piezo top-plate. :A is returned on completion, :N-5 is returned if the routine failed.

X argument sets the auto calibration type to perform. 0 is for short calibration (default) i.e. only strain gauges offset is adjusted. While 1 is long calibration routine, with adjusts both strain gauge offset and the feedback gain. You will need a length gauge to run the full calibration routine. Ss z command is not applicable, settings will revert back to default when controller restarts. Note: Long calibration is not implemented for ADEPT card with TG-1000. Usage will end in an error.

Y argument sets the axis index to which the length gauge is assigned. Default is 0 i.e. X index in a 4 axis build. Ss z command not applicable, settings will revert back to default on controller restart.

Z argument sets the delay between routine runs, default is 35 i.e. 35ms. Units are in milliseconds. Ss z command not applicable, settings will revert back to default on controller restart.

F argument sets the position where controller moves the piezo top-plate before adjusting the strain gauge offset. Accepts values between 1 to 100, units are %, default is 50 i.e. middle of the piezo range. Ss z command is applicable, settings will be saved between controller restarts.

Please use HALT command to stop a running calibration routine; else the routine will leave incorrect settings on the ADEPT card.

Shortcut RM
Format [addr#]RBMODE [X=control] [Y=axis_byte] [Z=buffer_pointer] [F=mode_byte]
Type Card-Addressed
Remembered Using [addr#]SS Z
Firmware Module Required RING BUFFER

Provides control of movement and save operations involving the controller’s internal 50-position ring-buffer (optionally to 250 positions, contact ASI). The LOAD command is used to fill the ring buffer.

The command, without any arguments, sets the TTL input interrupt flag and performs the same operation that a TTL IN0 input pulse would control as determined by the current IN0_mode. See TTL command.

A move to the Next Position may be initiated by:

  • a TTL pulse when the appropriate IN0_mode is selected (See TTL command, IN0_INT Firmware Module Required).
  • a short press and release of the @ button (as long as other special functions are not utilizing the @ button).
  • by the RM command without arguments.

RM X? returns the number of positions defined in the ring buffer (Tiger firmware v2.89+ or MS2000 firmware v9.2g+).

The argument variables are defined as follows
control

0 – Clears the ring buffer (RING_BUFFER firmware required)
1 – Starts array scan (ARRAY_MODULE firmware required)

axis_byte

1-7: Binary value determines which axes are commanded to move; the same axes’ positions are reported using IN0_mode=5. The ordering of axes is generally the order on the card/controller, with the first axis getting the LSB. The axis ordering can also be ascertained using the Z2B command; axis number 0 gets the LSB, axis 1 gets the 2s position in the binary value, and so on. The axis_byte setting also applies to the SERVOLOCK_TTL module and TTL-triggered moves.

buffer_pointer

sets or reads the pointer to the buffer position for the next move. The buffer pointer is zero-indexed, so its maximum value is the one less than the number of positions in the ring buffer.

mode_byte

On Tiger v2.81-2.88 these were on X pseudoaxis instead of F

Lowest two bits are used to specify the mode:

0 – reserved.
1 – TTL triggered mode (default). A TTL pulse or RM command without arguments moves to the next position.
2 – One-shot autoplay mode. A TTL pulse or RM command without arguments plays the ring buffer from the current position to end with a delay between points set by RT Z (make sure delay is set appropriately; e.g. setting 1ms won’t work with motorized stage).
3 – Repeat autoplay mode. Upon a TTL pulse or RM command without arguments, plays from current position continuously in a loop with delay set by RT Z (make sure delay is set appropriately; e.g. setting 1ms won’t work with motorized stage). While running, another trigger causes autoplay to stop. Also enables repeat mode for ARRAY module. Starting v3.24, this mode works on TGLED card too. When TTL X=21, TGLED cycles thru all LED channels without waiting for a TTL trigger.
Bits 3-7 are reserved.
MSB – read-only, set to 1 if ring buffer is auto playing and 0 otherwise

CAUTION: If you are using TTL mode 12 (see the TTL command), the values entered into the ring buffer using the LOAD command represent RELATIVE coordinates, not ABSOLUTE coordinates. You must drive the stage to the appropriate starting position before triggering a ring buffer sequence.

Command:RDADC (RA)

MS2000 Syntax and Function
Shortcut RA
Format RA [X] [Y] [Z] [F]

Returns the present values on the MS2000's 4-channel ADC. The X and Y channels are used for the joystick. The Z and F channels may be used for special applications, e.g. Autofocus or ADC_LOCK and ADC_FOLLOW modes of controlling the stage. Special firmware is required for these applications.

If the system has Video Autofocus user can query the focus score with the Z parameter ie RDADC Z?

If the system has Temperature Sensor user can query the temperature in 1/100 celcius with the T parameter ie RDADC T?

Example

Shortcut RB
Format RDSBYTE axis [axis] [axis]…
Type Axis-Specific

Requests the TG-1000 and MS-2000 to respond with the Status Byte.

The number is one byte, which can be broken down into 8 bits that represent the following internal flags:

Bit 00 = No commanded move is in progress.
1 = A commanded move is in progress.
This bit is synonymous with the STATUS command. If the bit is set, then STATUS returns B, otherwise STATUS returns N.
Bit 10 = The axis is disabled. It can be renabled by one of the following:
High Level command MC <axis>+, cycling the clutch switch for the Z-axis, Low Level StartMotor command (hex 47), or a system reset.
1 = The axis is enabled.
Bit 20 = Motor is inactive (off),
1 = Motor is active (on).
Bit 30 = Joystick/Knob disabled,
1 = Joystick/Knob enabled
Bit 40 = Motor not ramping,
1 = Motor ramping
Bit 50 = Ramping down,
1= Ramping up
Bit 6Upper limit switch:
0 = open,
1 = closed
Bit 7Lower limit switch:
0 = open,
1 = closed
Reply

: <byte as hexadecimal>

Example
RB X
:<0x8A>
RB X Y
:<0x8A><0x02>


The X-axis example value of 0x8A means the following:
B7: 1 -X Axis is at its lower limit
B6: 0 -X Axis upper limit switch open
B5: 0 -Ramping down, if ramping
B4: 0 -Motor not ramping
B3: 1 -Joystick/Knob is enabled
B2: 0 -Motor power is off.
B1: 1 -X Axis is enabled
B0: 0 -No commanded move is in progress

Note: Motor power can be on while a commanded move is not in progress and the stage appears not to be moving. This happens when the motor is either making a final adjustment to a commanded move or when it is applying a force to maintain the stage position.

On MS2000 and RM2000
Shortcut RT
Format RT [X=report_time] [Y=pulse_length in ms] [Z=delay_time] [F=num_aves]
Remembered Using SS Z

The X argument sets the time interval between report events when using IN0_mode = 5, TTL triggered serial interface asynchronous reporting. The report_time value has an acceptable range from 20 to 32700 milliseconds. The default value is 200ms.

The Y argument sets the length of the TTL output pulse in ms when using any OUT0_mode that triggers a TTL pulse. (The Y arguments command has a slightly different usage on a TGLED card. Refer to TGLED card user guide for more details.)

The Z argument sets the post-move delay time in ms for sequenced arrays, and/or the delay between ring buffer moves when RB X is set to autoplay (mode 2 or 3). Note that for ring buffer moves the delay time specifies the interval between attempted moves, whereas for sequenced arrays the delay specifies the time between arriving at the desired position and initiating movement to the next position. For ring buffer if the delay time is set to be 0 then the actual time between moves will be the axis loop time (generally 0.25ms times the number of axes, e.g. 1ms for a four axis card).

The F argument sets num_aves, the power-of-two exponent for the number of samples to be averaged. Used with the CRISP system.

On Tiger with Micro-mirror for SPIM
Shortcut RT
Format RT [F=scan duration] [R=laser duration] [T=camera duration]
Remembered Using SS Z

Sets the duration of output pulses from the Micro-mirror card while the SPIM state machine is running. All units in milliseconds and are currently rounded to the nearest 0.25ms. Scan duration specified is one-way time (in v3.13 and earlier the value from SAF was used instead).

On Tiger with MicroMirror and Phototargeting
Shortcut RT
Format [Addr#]RTIME [Y=laser_duration] [Z=delay_time]
Units Milliseconds
Type Card-Addressed
Remembered Using [Addr#]SS Z

The Y parameter laser_duration sets the time that the laser is turned on in milliseconds, essentially the same as TTL pulse length as described in the main TG-1000 programming manual. The setting applies to both moves initiated by AIJ as well as to ring buffer moves. Normal moves using MOVE or MOVREL commands will not turn on the laser. Its value should be between 1 and 65000. The Z parameter delay_time remains exactly as described in the main TG-1000 programming manual: the delay between ring buffer moves. If delay_time is less than (laser_duration + settle_delay) then the ring buffer behavior is unspecified. Its value should be between 1 and 16000

On Phototrack systems
Shortcut RT
Format RT [X=report_time]
Remembered Using SS Z

Sets the time interval between report events when using TTL X=5 TTL triggered serial interface asynchronous reporting. The report_time value has an acceptable range from 20 to 32700 milliseconds. The default value is 200ms.

To turn ON/OFF serial position logging first set the ttl_function to serial logging using TTL X=5. Then either RM command without any arguments, or a TTL pulse on the INPUT BNC will toggle the serial reporting function ON or OFF. To change the reporting time interval use RT X=report_time. Save any changes you wish to keep using SS Z.

With SERVOLOCK_TTL Function
Shortcut RT
Format RT [R= duration threshould]
Remembered Using SS Z

Sets the trigger duration threshould for the SERVOLOCK_TTL functionality (pulses longer that the threshold are considered “long” = negative move and shorter are considered “short” = positive move. Restricted to units of 0.25 milliseconds. Defaults to 0.75 ms.

Shortcut RU
Format RU [axis] = [distance]…
Units millimeter
Type Axis-Specific
Remembered Using [addr#]SS Z

This command sets the servo loop error limit before the motors will be disabled. The value n, is the distance in millimeters that the internal servo target and the actual position can differ before the motor is disabled. Default is 1 to 2 mm. If spurious disable conditions are encountered, increase this number. For more sensitive crash protection, decrease this number. Prior to MS-2000 version 9.2f and TG-1000 version 3.20 a single value applied to all axes (Tiger card-addressed) but afterwards it is axis-specific. Prior to MS-2000 version 9.2m and TG-1000 version 3.20 only integer values were allowed, but afterwards floating point numbers are allowed and reported.

Reply

A positive reply of :A is sent back when the command is received correctly.

MS2000 Example
RU X=5	
:A

Sets runaway sensitivity to 5mm on the X axis for 9.2m and later, sets the sensitivity on all axis for 9.2l and earlier.

Tiger Example
1RU X=5	
:A

Sets runaway sensitivity to 5mm on all axes in card #1 in v3.19 and earlier, would only set the X axis (assuming it's on card #1) on v3.20 and later.

Type Axis-Specific
Remembered Using [addr#]SS Z

This command sets the period of the pattern, in units of milliseconds in case of internal clock (default, see SAP) or in number of clock edges for external clock. Note that the triangle pattern and square wave pattern will automatically force themselves to have a period of an even number of milliseconds, even if the user specifies a period of an odd number of milliseconds. When period is set to be 1msec, the resulting behavior is undefined.

Note: On MicroMirror the actual waveform output is modified by the filter (tunable with BACKLASH), especially when the period is set to be less than 10msec.

Example
SAF A=10  
:A

Sets up the period of the pattern at 10msec or 100Hz.

Sets the single-axis mode according to the integer code.

Code Meaning
0 Puts single-axis mode in idle state (i.e. stops it if running)
1 Puts the single-axis mode in active state (i.e. starts generating the pattern)
2 Arms the trigger; on receipt of a TTL trigger pulse the single-axis mode becomes active. Pre Tiger version 3.31 after the TTL routine the pattern was free running. Post 3.31, the routine only cycles once, then waits again for another TTL trigger.
3 Makes the single-axis mode active and restarts the pattern of any other axis on the same card so they will be synchronized
Example
SAM A=0  
:A

Disables the routine for the A axis 

SAM A=1  
:A

Enables the routine for the A axis 

SAM B=2  
:A

Arms the routine for the B axis. The routine for B will start running on receipt of a TTL pulse. Pre Tiger version 3.31 after the TTL trigger the routine was free running. Post 3.31, the routine only cycles once, then waits again for another TTL trigger.

Works with TTL X=30 mode. 

SAM B=3  
:A

Enables the routine for the B axis. Also the routine for A axis is reset, so they will both run in sync

This command sets the position of the center position of the single-axis pattern. For example, if the offset is 1000 and the peak-to-peak amplitude is set to 1000, the pattern will go between positions 500 and 1500.

Note that manual moves (e.g. with joystick or wheels) while a single-axis pattern is being generated automatically adjust the single-axis offset value, such that this command may not be needed.

As of Tiger firmware v2.82, using the “+” operator instead of specifying a position will store the current position to the offset for the specified axis. For example, SAO A+ set the position of axis A to the center position of the single-axis pattern

Example
SAO A=1000  
:A

Sets offset of the offset of the pattern to be 1 degree for (MicroMirror) axis A.

Sets which axes are to be used for 2-D raster scan. The same axis settings also apply to the ARRAY module. The fast-scanned raster axis (horizontal) is defined by scan_axis = 1; the slow-scanned axis (vertical) is defined by scan_axis = 2. Single axis scans (1-D) requires setting the unused axes scan_axis = 0, and the driven axis as scan_axis = 1.

The scan pattern may be set to 0 for RASTER scans or 1 for SERPENTINE scans.

Without arguments, the command SCAN initiates (or stops) a scan using parameters set with the SCANR and SCANV commands.

Note multiple small changes in usage from MS-2000 command set.

Specifying an argument for the pseudoaxis X in decimal sets the state directly (see table below; the value is simply the decimal representation of the corresponding state character). Note that the firmware expects only certain states to be set by the user (marked as “OK to set” in the table); setting to a different state may yield unpredictable results. Querying the pseudoaxis X value returns the character associated with the current state.

Specify the cards axis ID as the fast_axis_id or slow_axis_id (axis IDs are obtainable using Z2B query; they are 0 and 1 for X and Y axes respectively on a two-axis motor card). If slow_axis_id is set to 9 then a true single-axis scan will be executed (not even anti-backlash moves on the slow axis); if slow_axis_id is specified but the slow axis start and stop positions (NV X and NV Y) are equal then a single-axis scan will execute but the slow axis position will be checked at the scan turnaround points.

The scan pattern may be set to 0 for RASTER scans or 1 for SERPENTINE scans.

Without arguments, the command SCAN initiates (or stops) a scan using parameters set with the SCANR and SCANV commands.

Firmware Required SCAN

Sets up raster scan start and stop positions, with the position values expressed in millimeters. During scanning, the stage will move past both of these positions slightly, so that when scanning within the range specified, the scan proceeds with uniform speed (set by the SPEED command). On units equipped with hardware position Sync, the output pulse goes high as the stage crosses the start position. On systems with the ENC_INT firmware module, an output pulse will occur every enc_divide number of encoder counts.

If the user specifies the #_pixels, the stop position will be calculated based upon the enc_divide and start position.

On TG-1000 v3.30 and later use retrace_speed to specify the speed of the retrace move as a percentage of the max speed (decimal value between 0 and 100). The default value of 67 was the hardcoded value previously. This feature can be added to MS-2000 on customer request.

Firmware Required SCAN

X, Y, and Z parameters set up the slow-scan (vertical) start and stop positions, with the position values expressed in millimeters, and the number of lines. The stage will move to the start position before beginning the scan. The scan range will be divided into number_of_lines lines. Following a completed horizontal scan, the stage will move vertically to the next scan line. The processes will conclude when the stage has moved to the vertical stop position and completed the last horizontal scan. If the start and stop values are identical then a 1-D scan will occur, repeated number_of_lines times.

The F and T parameters pertain to the fast-scan (horizontal scan) motion, and there is a difference between the behavior of the F parameter on TG-1000 vs. MS-2000.

On MS-2000, overshoot_factor (F) sets the amount of extra motion to account for the acceleration ramp at the start and stop of the trace. An overshoot_factor=1.0 (default) sets the pre and post move distances equal to the ramp up and down distances. Using a larger number will allow for more time to reach constant speed before the active sweep region.

On TG-1000, overshoot_time (F) sets an additional settling time in ms for the stage velocity to settle before reaching the start position (beyond the always-required ramp time set by the AC command). Thus the time required between scan line initiation and reaching the start position is given by summing the AC time and the NV F time. The same delay occurs after the stop position except for raster scans in firmware v3.20 and higher in which case the after-stop overshoot time is capped at 10ms. The default value is 50ms.

The T parameter was partially implemented for TG-1000 firmware versions 3.17 and 3.18, absent in 3.19, and then present in 3.20 and greater. It is intended mostly for scan-optimized stages that have a significant amount of physical backlash. The default value is 0.02 when the SCAN_OPTIMIZED define is enabled and 0 otherwise. If the value is non-zero there are several changes to the scan operation: (1) There is an extra overshoot move performed (with amplitude specified by the parameter) before any scan move in either direction, which ensures that the physical backlash is removed correctly before beginning each scan pass. (2) Before the scan moves begin, an initialization move to the center of the range is made to ensure that the overshoot move happens correctly. (3) When the scan moves are complete, the stage moves to the center position (otherwise behavior is to move to the start position).

With inserts equipped with Solenoid lock mechanism, this command is used to lock or unlock samples on the stage.

X argument accepts either “0” or “1”. “0” is the locking command , and “1” is the unlocking command. The Solenoid use no power when in “0” or lock position , so this is the default and the controller's initial state.

Y arguments is a percentage of power briefly applied to the solenoid to pull the lever back and unlock the wellplate. Set by factory, we recommend that this setting not be adjusted unless suggested by ASI support.

Z arguments is a percentage of power applied to the solenoid to keep it unlock. After unlocking, the solenoid needs very little power to keep the lever pulled back and keep the well plate unlocked. Set by factory, we recommend that this setting not be adjusted unless suggested by ASI support.

F argument sets the auto lock time, units are in minutes. When in unlock position , the solenoid is consuming power, over time solenoid will heat up and may damage it. There is a auto locking timer , Y sets the maximum time the solenoid stays unlocked , after which the controller auto locks. Default is 5 min . This feature can be disabled by setting Y as “0”, this is not recommended.

T argument, units are in millisec. This arguments sets the amount of time higher power (Y arguments) needs to be applied to unlock the wellplate. After that lower power (Z arguments) is applied to keep the wellplate unlocked. Set by factory, we recommend that this setting not be adjusted unless suggested by ASI support.

Note 1: Solenoid only consumes and dissipates power when in unlock state. Over time the heat generated by this power dissipation may damage the solenoid. So only unlock when needed.

Note 2: TTL Out mode must be set to 9 ie TTl Y=9 . This give control of the TTL out connector to Secure command .

This command sets/displays a fixed hardware HOME location for an axis in units of millimeters. The HOME position is considered a fixed hardware location and is adjusted properly when the controller’s coordinate system is altered with the HERE or ZERO function. The HOME position is automatically remembered and recalled through a power cycle and does not need to be saved using the SAVESET command. The home position defaults to a large positive number far exceeding the mechanical limits of the system, or else with the upper limit for DAC devices including piezos, micro-mirror, and tunable lenses.

If 1, then the stage seeks the upper limit. If -1, then the stage seeks the lower limit.

The stage moves to the hardware limit, backs away 3 mm, then approaches the limit slowly enough to maximize repeatability of the result. The recommended procedure is as follows, with SI and HERE commands using one or more axis arguments:

  • Send SI command.
  • Poll with STATUS command until ‘N’ is received.
  • Send HERE command with desired real world position.

Reply
If there are no errors, a positive reply of “:A” is sent back after issuing the command. If an error occurs during execution it will be reported then.

Auto Homing For Clocked Devices like Sliders
As of firmware 9.2l (for MS2000) and 3.18 (for Tiger) Seek Limit routine performs an additional step for clocked devices. After finding the Limit it moves a set distance (distance is specified as Home Position Command:SETHOME) and zeros itself there. By default, the distance between Upper limit and Slot 1 is saved in Home position , so when Seek Limit is run , the controller is able to move the slider to position 1 by finding the limit and moving a set distance from it.

MOVE X=12345
:A
STATUS
B
/
N

In this example, the command MOVE started the X-axis moving towards the position 1.2345 millimeters from the origin. The first STATUS command returned a B showing that the motor is still busy moving towards the target. The second time, the STATUS command returned an N signifying that the MOVE command is finished and there is no longer any motor movement.

Command:TTL

TTL Has different syntax and slightly different function if you have a Tiger(TG-1000) or MS2000 and RM2000 controller.

On Tiger
Format [Addr#]TTL [X=IN0_mode] [Y=OUT0_mode] [Z=aux_IO_state] [F=OUT0_polarity] [R=aux_IO_mask] [T=aux_IO_mode]
[Addr#]TTL (firmware v3.16+)
Type Card-Addressed
Remembered Using [Addr#]SS Z

Only partly implemented in TG-1000

The MS2000 controller has a buffered TTL input (IN0) and output (OUT0) port as well as several unbuffered I/O ports. The signals IN0 and OUT0 are found on the board connector SV1 pin1 and 2 respectively. On many controllers, these signals are connected to the IN and OUT BNC connectors on the back of the controller. The IN0_mode and OUT0_mode parameters set with this command determine the character of the I/O pins. It’s a Card-Addressed command.

IN0_mode

0 - turns off TTL IN0 controlled functions; TTL interrupt DISABLED.

1 – TTL IN0 initiates a Move-to-Next-Position of the stored positions in the Ring Buffer pointed to by the buffer_pointer. When the buffer_pointer reaches a value equal to the number of saved positions, it resets to the first position, allowing cyclic repetitions to the saved locations. See RBMODE and LOAD command.

2 - TTL IN0 repeats most recent relative move (See MOVREL) For example, begin a session by issuing the command MOVREL X=0 Y=0 Z=0.5, and each subsequent move to Next Position will cause the Z axis to move 0.05 micron. This function can be used for repetitive relative moves of any axis or combination of axes. You may directly set the dZ value with the ZS command’s X parameter for the specified focus axis but not for others.

3 – TTL IN0 initiates an autofocus operation on systems with autofocus installed.

4 – enables TTL IN0 controlled Z-stacks. (See ZS command).

5 – enables TTL IN0-started position reporting via the serial interface. Information is asynchronously sent out the serial interface every report_time interval, where report_time is set with the RT command. Data returned in the serial stream are the elapsed time in milliseconds since the TTL trigger, followed by the position of each axis enable by the axis_byte. On TRACKING systems, the PMT sum signal is also reported. Reporting is toggled on and off by the TTL input pulse.

6 – TTL interrupt ENABLED; use with TTL triggered position reporting.

7 – TTL commanded ARRAY move to next position.

9 – Used with CRISP focus lock. TTL IN0 HIGH engages lock if the system is in the READY state. TTL IN0 LOW will cause the system to UNLOCK is locked already.

10 - Toggle TTL OUT0. If TTL OUT0 is set either LOW or HIGH, an input pulse on the TTL IN0 will cause the output to toggle to the other state.

11 - SERVOLOCK_TTL mode (must have firmware support; prints SRVLK_TTL in the BU X output). To engage the SERVOLOCK_TTL mode use the LK command which will then automatically change the TTL IN0 mode and normally will restore it afterwards. When the SERVOLOCK_TTL mode is engaged do not change the TTL X setting. For further documentation see the SERVOLOCK_TTL documentation.

12 – Behavior is exactly the same as mode 1 above except the moves are relative rather than absolute.

CAUTION: If you are using TTL mode 12, the values entered into the ring buffer using the LOAD command represent RELATIVE coordinates, not ABSOLUTE coordinates. You must drive the stage to the appropriate starting position before triggering a ring buffer sequence.

20 – Used with TGLED card, All LED channels remain off until a TTL pulse is received on the TTL IN connector. On the Rising edge of the TTL pulse, the LED channels turn ON and remain ON for a fixed duration set by the RT Y command. Intensity will be as set by the LED command.

21 - Used with TGLED card, TTL Pulses cycle thru channels of the TGLED card one at a time turning them ON for a set time. On the Rising edge of the TTL pulse, only ONE LED channel turns ON for a fixed time. Then on next TTL pulse, the next LED channel turns ON for a fixed time and so on. Starting v3.24, when RB F=3 TGLED card cycles thru all channels without waiting for TTL pulses. If an intensity is set to 0 using the LED command then that channel is automatically skipped.

22 – Used with TGLED card, Same as Mode#20 except waits for TTL pulse to go low before turning off the LED. Setting RT Y isn't required. Available in firmware 3.30 and above.

23 - Used with TGLED card, Same as Mode#21 except waits for TTL pulse to go low before turning off the LED. Setting RT Y isn't required. Available in firmware 3.30 and above.

30 - Used with Single Axis function SAM [Axis]=2. On rise edge of TTL pulse, the routine is performed once.Available in firmware 3.30 and above.

OUT0_mode

0 – TTL OUT0 unconditionally set LOW.

1 – TTL OUT0 unconditionally set HIGH.

2 – generates TTL pulse at end of a commanded move (MOVE, MOVREL, move via ring buffer, or via array module). The pulse duration is set with command RT Y=???.

3 – output TTL OUT0 gated HIGH during axis index 0 (X) constant speed move.

4 – output TTL OUT0 gated HIGH during axis index 1 (Y) constant speed move.

5 – output TTL OUT0 gated HIGH during axis index 2 (Z) constant speed move.

8 – TTL OUT0 timed arrival pre-pulse output. See RT command. Requires PREPULSE firmware module.

9 – TTL OUT0 PWM and MicroServo Output. See the LED or the SECURE command. Requires LED_DIMMER or USERVO firmware module

10 – output TTL OUT0 gated HIGH upon completion of video AUTOFOCUS function. AUTOFOCUS hardware and firmware required.

11 – generates TTL OUT0 pulse at end of commanded move providing CRISP is in ‘F’ state. Waits for CRISP ‘F’ state after move completion to send a pulse. Also enables CRISP status busy poling that will not return 'N' until CRISP is in the In-Focus 'F' state.

12 – TTL OUT0 high when CRISP is ‘F’ state, low otherwise.

20 – TTL OUT0 set during SPIM state machine operation. Requires MM_SPIM firmware module. Until v3.12 was code 10 (changed to avoid MS2000 conflict)

21 – TTL OUT0 set at the end of a ring buffer move or AIJ-initiated move (for laser trigger). Requires MM_TARGET firmware module. Until v3.12 was code 11 (changed to avoid MS2000 conflict).

22 - In this mode, TTL OUT0 is controlled by Single-axis function module. With the SAP command the user can generate a TTL pulse that is synchronized with Single-axis function actuator motion. Available only in firmware version 3.17 and above.

OUT0_polarity

1 – default polarity, -1 inverts the polarity of TTL OUT0.

aux_IO_state

Requires TTL_AUXILIARY firmware module; behavior depends on the firmware build and hardware present. Sets the state of the auxiliary TTL output according to the aux_IO_mask. Input and output as a decimal number representing the binary pattern desired. The following uses have been defined so far:

For MM_SPIM firmware with SPIM TTL card: Bit0 = Side0/Laser0 output, Bit1 = Side1/Laser1 output

aux_IO_mask

Requires TTL_AUXILIARY firmware module; behavior depends on the firmware build and hardware present. Controls how the aux_IO_state bits are used, or how the backplane is used when aux_IO_mode is set to 2. Input and output as a decimal number representing a binary mask. If the corresponding mask bit is set to 1 then the state bit will be reflected at the output, but if the mask bit is 0 then the state bit has no effect. The following uses have been defined so far:

For MM_SPIM firmware: Defaults to 3 = 0b00000011.

aux_IO_mode

Requires TTL_AUXILIARY firmware module; behavior depends on the firmware build and hardware present. The SPIM state machine overrides these setting during its operation.

0 – TTL outputs determined by aux_IO_state/mask.

1 – TTL outputs determined by the LED command (requires MM_LASER_TTL module). The default setting for MM_SPIM firmware.

2 – Simulates a TTL input from the backplane. The backplane value is masked by aux_IO_mask and the binary value is considered. If a 0-1 transition occurs then a TTL input pulse is simulated and action will be taken depending on the setting of IN0_mode. The default setting for TTL_AUXILIARY on piezo firmware.

Without any Argument

In firmware version 3.16 and above , When TTL command is issued without any arguments , like [Card Addr#]TTL , the controller report the state of TTL IN. The controller replies with :A 0 when signal is low. and :A 1 when TTL IN sees a high signal.

For Clocked Position devices

UM command has no effect if the axis is a Clocked Device like Filter Slider , Objective slider or Objective Turret.

As of Firmware version 9.2l (for MS2000) and 3.18 (for Tiger) , when UM for a Clocked Device is set to “1” , Where command prints the Axis position in MilliMeters instead of Slot Position. Move command continues to work, while Relative move doesn't. This feature is mean for troubleshoot and diagnostic usage only and not meant for regular operation.

Without arguments, this command unlocks the servo from the focus system and returns control to encoder feedback from the Z-axis drive. The focus error offset is not changed.

The LED_Intensity may be set from 0 to 100 (%) of full power using the X argument. Default is 99.

Update_Skip is used to reduce the update rate of the CRISP system to the motor drive system. Default is zero. Increase Update_Skip to improve stability when using piezo Z-axis drive systems and higher loop gain settings.

Rel_LK_knob_spd (default 2) controls the sensitivity of the control focus knob when the system is locked. This will vary depending on the calibration factor that the system finds, so don’t be alarmed if you find large sensitivity differences with conditions.

To select active Z-focus axis: If the controller can handle more than one Z-axis focus device, you can specify the focus_index to select which one is active for the CRISP, TRACKING or ZS functions. Specify as a 0-indexed number; find the axis index from the letter using Z2B command or else parse the output of the BU X command and figure out what number in order the axis letter is).

Sets the length of time msec, in milliseconds, the controller will pause at the end of a move. The busy status is not cleared during this pause state, unless the MAINTAIN behavior for the axis is set to code=3. Additionally, a P is displayed on the LCD display when in the Pause state. During the Pause state, the servo loop remains actively attempting to position the axis on target.

For a piezo stage axis, the controller enters the Pause state as soon as the command is received and the voltage applied to the piezo. The controller remains BUSY until the Pause state times out. Typically used to allow for piezo stage settling time.

For Phototargeting or MM_TARGET firmware , this can be used to specify the amount of time between the move initiation (either a ring buffer move or from the AIJ command) and when the laser pulse turns on. Thus it would normally be non-zero for at least one of the micro-mirror axes involved in phototargeting. Default for all axes in MM_TARGET firmware is 5 ms (usual default is 0 ms).

The Maximum amount of current a TGLED Rev A card can output on each LED channel is 1.2Amps. When the X argument is set to 75, then maximum current each channel will output is reduced to 75% of 1.2Amps i.e. 0.9Amps.

This command can be used as a quick way to adjust the brightness of all LED channels. Default is 75%, ASI recommends not exceeding this limit.

Example 

1WRDAC X=50
:A

Limits the maximum current output on each channel to 50% or 0.6Amps 

1WRDAC X? 
X=50 :A

Queries the card for maximum current percentage.

On MS2000 and RM2000
Format WRDAC X=[0 to 10]

Remembered Using [Addr#]SS Z

This command is “recycled” for a slightly different use on TGPMT card than for other cards . In the context of a TGPMT card this command is used to set the PMT's control voltage or gain. When set to 0 , PMT output signal drops to 0Volts , turning it off. When set to 1000 , 100% of control signal (1 Volts incase of H10722) is applied to the PMT.

X sets the gain for PMT0

Y sets the gain for PMT1

This function does the same function as the Dials on TGPMT cards faceplate.

Example 

7 wrdac x? y?
X=500.000000 Y=0.000000 :A

Queries the TGPMT card at Address 7 for PMT gain settings. PMT0 is at 50% gain , PMT1 is at 0% gain and so is off. 

7wrdac x=505 
:A

Sets the gain of PMT0 at 50.5% on TGPMT card at address 7

Type Axis-Specific
Remembered Using [addr#]SS Z

Allows the user to change the axis name for a motor axis. The current_axis_letter must be one of the motor axes names listed with the BU X command. The new_axis_letter_ascii_code must be the decimal ASCII code for the desired axis name for letters between upper case A(65) and Z(90). For the change to take effect, the new setting must be saved to flash memory using SS Z, followed by a hardware reset. The new axis name will remain in effect unless default settings are restored to the controller.

If the Z2B value of an axis is queried (e.g. Z2B Y?), the axis’ index on the card is returned (e.g. :A Y=1 for the 2nd axis on the card).

Type Card-Addressed
Remembered Using [addr#]SS Z

Sets parameters for use with TTL triggered Z movement. User must set TTL X=4 for this trigger mode to be active. When a positive TTL edge is detected, the Z-axis is moved by an amount dZ (expressed in 10th microns units). This move distance is repeated for n TTL triggered moves. If mode=1, the stage will step in the opposite direction for n moves, then turn around again, repeating a triangular waveform cycle. If mode=0 the stage will return to the original position after n moves and repeat a saw-tooth waveform cycle.

The stage will move to the starting position upon receiving the first TTL pulse after waiting more than stack_timeout milliseconds (default 500ms) from the previous pulse.

Th axis moved by the TTL is the designated “focus index” (also the axis used for CRISP among other things). Use UNLOCK F to read or set the axis letter corresponding to “focus index”. Note the setting has to be changed, settings saved, and the controller reset or power cycled for the new setting to take effect. If the controller has a piezo but no motorized focus drive then the piezo axis should be set as the “focus index”. If both are present the “focus index” normally default to the piezo.

Backlash : ZS routine also performs the backlash compensation move for each step. For step size smaller than 10 microns, this might result in issues like irregular step sizes. Consider disabling Command:BACKLASH for smaller step sizes.

Stack Timeout : If the TTL frequency is less than 2Hz , then the controller might consider it a stack time out condition. Consider increasing the Stack timeout to accommodate the slower TTL frequency, to avoid any issue.

If there are no errors, a positive reply of :A will be returned. Example

TG-1000 and MS-2000’s instruction set differences

This section is intended to quickly bring the users up to speed on the major differences in the serial commands between TG-1000 and MS-2000 controller.

Where possible the TG-1000 commands were kept close to the MS-2000 controller commands.

The Tiger reply syntax, described above, was added to Tiger starting in COMM card firmware v1.92.

Commands where the axis letter is specified work just like MS-2000, e.g. MOVE, MOVREL, and WHERE. For example, X and Y axis reside on card with address 1, and Z resides on card with address 2. When M X=## Y=### Z=### is issued the COMM card in TG-1000 controller parses the command, and redirects the command to the appropriate card automatically. These commands are called Axis-Specific Commands. A card address should not be specified with an Axis-Specific command, otherwise undefined behavior may result from any mismatch between the address specified and the card with the axis as determined by the COMM card.

The TG-1000 is able to support multiple add-ons like CRISP and Piezo stages whereas MS-2000 was only able to support one, so we were forced to alter the command set to handle commands which are intended for a certain card but do not contain the axis name. In those cases, the user must specify which card the command is intended for, and the COMM card will relay the command appropriately. For example, the SS Z command saves the settings into non-volatile memory, but the user may not want all the settings on all the cards to be saved. For the TG-1000 the user has to add the card address in front of the command to make it work. For example, if the card that drives XY axis has the address 1, to only save setting on this card user should issue 1SS Z. These commands are called Card-Addressed Commands.

Importantly, for Card-Addressed Commands the setting applies to all axes on the card. For example, the ring buffer delay can be set independently for the XY stage on one card and a piezo stage on a different card. However, if a card contains more than one independent axis (e.g. a ZF card for two linear stages, or a Micro mirror card for 2 scanners) then the same setting applies to all axes. Continuing our example, the ring buffer on the ZF card would control both Z and F axes (though one of these axes could be disconnected from the ring buffer) so Z and F could not have separate ring buffer delay times.

Various methods of determining the address of a specific card are given below.

A third category is Broadcast commands, like STATUS, HALT, RESET, and ZERO. They are routed to all cards in a TG-1000 system by default, just like the MS-2000. However, in most cases they can also be directed at a single card by simply adding the card address, so they could be considered as special type of Card-Addressed Commands sent to all cards if an address is not specified.

A final category includes commands that default to a particular card, though they can be addressed to specific cards as well. There are sub-categories of commands sent to the COMM card unless otherwise specified (e.g. BUILD and WHO), commands sent to whatever card has the X axis or else all the stage cards if the X axis doesn’t exist (e.g. JSSPD and LED), and commands sent to whatever card has the Z axis or all the stage cards if the Z axis doesn’t exist (e.g. most CRISP and autofocus commands). These sub-categories may be referred to as Comm-Default, Stage-Default, and Focus-Default commands respectively.

Beginning with COMM card firmware version 3.10 a special axis letter * was added. When this character is specified in an Axis-specific command then it applies to all the axes in the controller. For instance, all axes can be moved to zero position using M *=0. The * axis letter can also be combined with card addressing to apply the command to all the axes on the same card, e.g. 3M *=0 will move all axes on card address 3 to their zero position, and 3! * will home all axes on card 3.

How does the user find out a card address?

When the TG-1000 is turned on or when WHO serial command is issued, the controller prints out card address, axis names, firmware version and firmware build date of all the cards installed in the system (see section Tiger Banner below for more details). Also, more complete information about the cards and corresponding axes can be accessed using the BUILD X command which is described in the section Build Command below.

As an illustrative example, the controller may have the following configuration as reported on startup: 

................................................................
At 30: Comm v1.5 TIGER_COMM May 07 2013:15:42:05
At 31: X:XYMotor,Y:XYMotor v2.4 STD_XY Jun 11 2013:17:00:12
At 32: Z:Piezo v2.4 ADEPT_PIEZO Jun 11 2013:17:05:00
Joystick ready.
System ready.

The card addresses are shown in ASCII code. At 31 indicates a card with X and Y axes has the address 1 (ASCII code of 1 is 31).

To save settings in non volatile memory: 1SS Z Card-Addressed
To print its error dump buffer: 1DU Y Card-Addressed
To move X and Y axis: M X=### Y=### Axis-Specific

Similarly the card with Z axis has address 2 (ASCII code of 2 is 32).

To move Z axis: M Z=### Axis-Specific
To issue pzinfo command on this card: 2PZINFO Card-Addressed
To put in closed loop external input mode: 2PZ Z=1 Card-Addressed
To save settings into non-volatile memory: 2SS Z Card-Addressed
To run short calibration on the piezo: 2PZC Card-Addressed

Table 1 TG-1000 addresses

Addressee Usage Value
TG-1000 Comm Hard coded, re-assignable 0x30 (‘0’)

Identifying Controller Configuration

Build Command

In Controller with Tiger Comm version v1.8 and above, the BUILD X command directed at the COMM card (or without any address) can be used to query axis names, axis types and axis address. (When the build command is addressed to a specific card the build information for that card is returned.)

Example:
build x
TIGER_COMM
Motor Axes: X Y P Q R S 0 1
Axis Types: x x u u u u w w
Axis Addr: 1 1 2 2 2 2 3 3
Hex Addr: 31 31 32 32 32 32 33 33
Axis Props: 0 0 0 0 0 0 0 0

The above system has card address 1 with an XY stage with axes named X and Y. Card number 2 has micro mirror with axes P,Q,R,S. Then card address 3 with filter wheel IDs 0 and 1.

The next line contains the axis type short code. For example, x means xy stage, u means micro mirror and w means filter wheel. A complete listing of axis types with designations is as follows:

The next two lines contain the addresses in two forms, first the form that is used to prefix Card-Addressed commands and second in hex format.

Finally, any special axis properties are printed (e.g. CRISP or SCAN capabilities) starting with firmware version 2.8. The decimal equivalent of a byte (0-255) is printed with the bits of the byte representing the following

Axis Type List
Axis Type Short Axis Type Long Description
x XYMotor XY stage
z ZMotor Z focus motor drive. LS50s, Z scopes etc
p Piezo Piezo Focus. ASIs ADEPT, Piezo DAC etc
o Tur Objective Turret
f Slider Filter Changer
t Theta Theta Stage
l Motor Generic linear motorized stage, TIRF, SISKIYOU etc
a PiezoL Generic linear piezo stage
m Zoom Zoom magnification motor axis
u MMirror Micro Mirror, Scanner 75 etc
w FW Filter Wheel
s Shutter Shutter
g Logic Programmable logic card
i LED card Multi LED Driver card
b Lens Tunable Lens
d DAC Digital to Analog converter(DAC)
u Unknown Unknown axis type
Axis Properties
Bit 0: CRISP auto-focus firmware
Bit 1: RING BUFFER firmware
Bit 2: SCAN firmware
Bit 3: ARRAY firmware or MM_TARGET firmware
Bit 4: SPIM firmware (v2.81+)
Bit 5: SINGLEAXIS and/or MULTIAXIS firmware (v2.81+)
Bit 6: LED illumination (v2.87+)
Bit 7: Reserved
Tiger Banner

A banner is printed by the controller on Startup and by the WHO command. It tells the user (and also to any scripts and programs) all the available cards in the system, with their axis characters, axis types etc. 

At 30: Comm v1.5 TIGER_COMM May 07 2013:15:42:05
At 31: X:XYMotor,Y:XYMotor v2.4 STD_XY Jun 11 2013:17:00:12
At 32: Z:Piezo v2.4 ADEPT_PIEZO Jun 11 2013:17:05:00

It is a multiline reply, each line is terminated by a <Carriage Return> and final line by a <Carriage Return> +<Line Feed> to designate end of Transmission.

Each line can be sub divided into strings using a white space as delimiter. Then the 2nd string is the card address in Hex. 0x30 is 0 in ascii, 0x31 is 1 and 0x32 is 2.All possible address are 0x30 to 0x39 and then 0x81 to 0xF5. 0x81 is ü, 0xF5 is ⌡.

The second string can be further subdivided with comma as delimiter. Then the first character of the string is the axis character, colon and what kind of an axis it is. A to Z are all possible axis names, system is case insensitive. Except in case of filter wheels, IDs are integers 0 to 9

Example:

X:XYMotor,Y:XYMotor . X and Y are axis names of a XY stage. Z:Piezo . Z is the axis names of a Piezo focus.

Then the 4th string is the firmware version number. 5th String is our build name, which is an internal designation. The last set of strings are the firmware compile date and time.

A Note Regarding Units

The most common commands including MOVE, MOVEREL, HERE, and WHERE use axis units, which can be changed using the UM command. However, some commands such as SETUP, SETLOW, and PCROS always use units of mm. By default, axis units where position is given in distance (e.g. for motorized stages and piezo stages) are represented in 0.1um increments, or 10,000 units per millimeter of travel. For mirror scanner axes, default axis units are 0.001 degrees (uncalibrated), or 1000 units per degree of travel. When a time is required, the unit is generally milliseconds. Some commands use integer codes or other input units as described below.
