Sinking Digital Output
The GPIC has 24 sinking digital outputs. Each sinking DO is connected to the breakout
connector. The sbRIO-9687 interface board uses some of the DO lines, which can be
disconnected from sbRIO-9687 circuitry by depopulating 0 Ω resistors.
The sinking DO lines have the same electrical specifications as the DO lines of the GPIC. For
more information, refer to the
NI 9683 User Manual and Specifications
or the
NI 9684 User
Manual and Specifications
. The GPIC has current sinking digital outputs, which means that
the output pin is driven to ground (GND) when the channel is ON.
The following figure is a block diagram of the sinking digital output.
