We are having the same issue. After some quick tests, we realized that if the pressure gauge is hooked up to the (+) and signal pins for one of the GPIO ports, the cRio always recognizes a "true" or "high" input. The GPIO pins seem to have pull-up resistors, so the only way to change the input value is to short (-) and signal. We are going to test this setup tomorrow (fingers crossed!).

Does anyone have any other ideas or confirmations for what we found?

EDIT: This worked.
