DI Port 1
The sourcing DI lines have the same specifications as the sourcing DI lines of the GPIC. Port 1
should be powered at the VI_P1 pin for proper operation. The digital input operates in the low
range or high range based on the VI_P1 voltage.
Note If no device is connected to the sourcing digital input, the channel registers as
OFF. If the input is connected to ground, the channel registers as ON.
Sourcing Digital Input Connector
Sourcing digital inputs are available at breakout connector J12. Refer to the following table for
pinout information.
