Shortcut RT Format [Addr#]RT [X=report_time] [Y=pulse_length in ms] [Z=delay_time in ms] [F=num_aves] [T=finish_error_time in ms] Type Card-Addressed Remembered Using [Addr#]SS Z
- 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.) Note that this delay is prematurely ended (and TTL state set LOW) if any move is initiated. For automatic array scanning with TTL outputs, also use the Z argument below, to make sure the array does not move on before the TTL timer is finished.
The Z argument sets the post-move delay time in ms for sequenced arrays, and/or the delay between ring buffer moves when
RM Xis 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). For automatically sequenced arrays, if
TTL y=2 or 11then this Z argument should be set the same as RT Y, so that the stage stands still long enough for the TTL timer to complete. Note that this is distinct from the time set using the
WAITsetting which introduces a user-set delay after landing at a position before the move is considered complete (affects both busy status and any TTL output pulse).
The F argument sets num_aves, the power-of-two exponent for the number of samples to be averaged. Used with the
The T argument sets finish_error_time, which is the total amount of time that a motorized stage has to spend within the finish error of the target position at the end of a commanded move (
PCsetting) before the busy flag is cleared and the move is considered complete. Added to Tiger firmware as of v3.34 (Oct 2020). Defaults to 3ms (previous to v3.34 firmware the setting didn't exist but its effective value was 0.5ms).
- On Tiger with Micro-mirror for SPIM
Shortcut RT Format RT [Z=delay_time] [F=scan_duration] [R=laser_duration] [T=camera_duration] Units Milliseconds Type Card-Addressed Remembered Using SS Z Firmware Required MM_SPIM
Sets up timings used in the high-level operation of SPIM state machine coordinated by Micro-mirror card. They are specified in ms with 0.25ms resolution. These commands augment, not replace, the other RTIME parameters applicable to all TG-1000 cards. For SPIM state machine triggered by TTL after arming, these values are usually “locked in” during the arming step (i.e. upon
delay_time is the delay between ring buffer moves just as normal, however it serves an added function: it is also the delay between the receipt of the trigger and the start of the SPIM state machine operation, allowing a systematic delay to be added. Note that resolution is 1 ms for this setting.
scan_duration: sets the duration of each beam scan during SPIM operation. Total beam scan time will be multiplied by the number of scans (NR X). Introduced in v3.14; in v3.13 and earlier the value for SAF <axis> was used instead. Cannot be less than 1 ms.
laser_duration: sets the duration that the laser control output stays high. Cannot be less than 0.25 ms.
camera_duration: sets the duration that the camera trigger output stays high. Cannot be less than 0.25 ms.
All units in milliseconds and are currently rounded to the nearest 0.25ms
- 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_durationsets 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_timeis the delay between ring buffer moves just as normal. However if
delay_timeis less than (
laser_duration + settle_delay) then the ring buffer behavior is unspecified. Its value should be between 1 and 16000.
- On Tiger with TGLED
Shortcut RT Format [Addr#]RT Y=[LED ON time on TTL trigger in ms] Units Time in millisec between 1 to 65000 Type Card-Addressed Remembered Using [Addr#]SS Z
The RT command's Y argument is “recycled” for a different purpose for the TGLED cards. Here it is used to set the duration the LEDs stay on after a TTL trigger.
Other Behavior and function of RT command have been left unchanged. Refer to the TG-1000 programming manual for more info.
- On Tiger with TGPMT
Shortcut RT Format [Addr#]RT Y=[PMT overload reset pulse duration] Units Time in millisec between 1 to 65000 Type Card-Addressed Remembered Using [Addr#]SS Z
The RT command's Y argument is “recycled” for a different purpose for the TGPMT cards. Here it is used to set the duration the Reset pulse to clear the PMT from Overload state. Overload reset pulse is generated when LOCK command is issued.
Assuming TGPMT card address is 7
7rt y=100 :A
7rt y? :A Y=100.000000
- 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
RMcommand 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.
