====== Command:RDADC (RA) ======

-->MS2000 Syntax and Function ^

^Shortcut  |RA | 
^Format  |RDADC [X?] [Y?] [Z?] [F?] [T?] [M?] |
^Units    |Integer|
^Remembered |Not Applicable|

Returns the present values on the MS-2000'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, for example Autofocus or ''ADC_LOCK'' and ''ADC_FOLLOW'' modes of controlling the stage.  Special firmware is required for these applications.

**X?:** Returns the ''ADC'' reading of the joystick X axis.

**Y?:** Returns the ''ADC'' reading of the joystick Y axis.

**Z?:** If the system has [[:video_autofocus|Video Autofocus]], the user can query the focus score with the Z parameter, for example ''RDADC Z?''.

**T? / M?:** If the system has a temperature sensor, the user can query the temperature in 1/100 degrees Celsius with the T parameter ie ''RDADC T?''
If there are two temperature sensors present, one connected to channel-1 and the other connected to channel-2 of an ''ADEPT'' Hub (I2C breakout board), then the M parameter also becomes active, for example ''RDADC T? M?'' would answer with '':A 2565 2389'' meaning sensor-1 has read 25.65C and sensor-2 has read 23.89C.


**Example**
	
<asi> $ RA X Y
:A 128 128</asi>

Shows typical ADC values for a centered joystick.

--> Tiger and TGPMT Syntax and Function ^

^Shortcut  |RA| 
^Format  |[addr#]RDADC  [X?] [Y?] [Z?] [F?] [T?] |
^Units    |Integer|
^Type    |Card-Addressed  |
^Remembered |Not Applicable|

On a ''TGPMT'' card in a Tiger Controller, this is a __Read Only__ command. It reports ''PMT'' signal read through an ''ADC'' onboard the ''TGPMT'' card. 

**X?:** Returns the ''ADC'' reading of ''PMT0''

**Y?:** Returns the ''ADC'' reading of ''PMT1''

**Z?:** Autofocus related, requires ''AUTOFOCUS'' firmware module.

**T?:** Temp sensor related, requires ''TEMP_SENSOR'' firmware module.

[[:tgpmt#adc_specification|ADC Specification can be found here.]] 

**Example**

If the ''TGPMT'' card address was **7**, 

<asi> $ 7RDADC X? Y?
:A 2 1</asi> 

"2" is the ''ADC'' reading from ''PMT0'', and "1" is the ''ADC'' reading from ''PMT1''

<asi> $ 7RA X? Y?
:A 2 1</asi>
