Routing a Matrox Iris GT auxiliary output signal to a third-party
device
You can route an auxiliary output signal from your Matrox Iris GT to a third-party
device. To do so, perform the following:
1. Connect the power, current-controlled output, and the digital I/O signals of your
Matrox Iris GT to the breakout board by following the steps in the Powering
Matrox Iris GT and connecting its I/O signals to the breakout board section.
2. If sending an auxiliary output signal from your Matrox Iris GT to a third-party
device, connect an open-wire cable from the third-party device to the breakout
board’s output connector.
• When connecting to a PNP-compatible PLC device, you can either add an external
pull-up resistor between the third-party device and your breakout board, or use
the breakout board’s output pull-up resistor.
- To use an external pull-up resistor, connect the wire from your external pull-up
resistor to the assoVDC wire terminal. This connection will power your
external pull-up.
For more information about connecting PNP-compatible PLC devices, refer

Connecting to a PNP-compatible PLC device subsection of the Connecting
external devices to auxiliary output signals section, in Appendix D: Using the I/O
signals and controlled- current output of Matrox Iris GT .
