130 Appendix F: The breakout board
Routing a signal from a third party device to your Matrox Iris GT
You can route a signal from a third-party device to your Matrox Iris GT. To do
so, perform the following:
1. Connect the power 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. Connect an open-wire cable from the third-party device to the breakout board's
input connector.
To adjust for the various current requirements of trigger and auxiliary input
signals, a serial resistor must be added between the third-party device and the
breakout board's input connector. For more information, refer to Connecting
external devices to input signals section, in Appendix D: Using the I/O signals and
controlled- current output of Matrox Iris GT.
