You can route an auxiliary output signal from your Matrox Iris GT to a third-party
device. To do so, perform the following:
breakout board by following the steps in the Powering Matrox Iris GT and
connecting its I/O signals to the breakout board section.
device, connect an open-wire cable from the third-party device to the breakout
board's output connector.
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 associated +VDC terminal block connector. This connection will
power your external pull-up.
For more information about connecting PNP-compatible PLC devices, refer
to 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 of Matrox Iris GT.
