Sinking Digital Output Configuration
The first seven digital output lines are used on the sbRIO-9687 interface board for inverter
signals. See Inverter Digital Signals on page 35 for more details. If sinking digital outputs
need to be used externally, they can be disconnected from onboard functionality by
depopulating the corresponding resistors. The following table provides information about the
onboard function and corresponding resistor for sinking DO signals.
