Command:WRDAC
- On Tiger with TGLED
-
Format [Addr#]WRDAC X=[1 to 100] Units Percentage between 0 and 100 Type Card-Addressed 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 maximum amount of current for all the LED channels.
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] Units Voltage, 0 to 10V Firmware Required 8.4f+ Lets the user set the voltage on header pin SV1-5 on WK2000 board. The voltage can be varied between 0 and 10 Volts, with an accuracy of 0.1V. Maximum Output drive current is 35mA. Input value in volts. Does not work with Piezo units. If using a a firmware build with “PZ” in the name, such as PZ_CRISP, commanded moves of the Z axis will be scaled using the CCA X command (minimum=0v, maximum=10.00v) and output on the analog 0-10V output BNC (SV1 Pin 5).
Example
WRDAC X=1.1 :A
Voltage on PIN SV1-5 is 1.1Volts
WRDAC X=20 :N-4 WRDAC X=-1 :N-4

Format [Addr#]WRDAC X=[0 to 1000] Y=[1 to 1000] Units integer, between 0 and 1000 Type Card-Addressed 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
