With A Push Button - Matrox Iris GT with MIL Manual

In addition, connect TRIG- to the ground of the third-party device. Alternatively,
turn on output-to-trigger bypass switch 2 (SW6[2]). This grounds the trigger
signal (TRIG-).
3. If routing auxiliary input signals that are not trigger signals, connect the ground
of the input connector (J32 or J33) to the ground of the third-party device
providing the signal.
Generating a Matrox Iris GT auxiliary input or trigger signal with
a push button
You can generate a Matrox Iris GT auxiliary input signal or a Matrox Iris GT
trigger signal using the push buttons on the Matrox breakout board. To do so,
perform the following:
1. Connect the power and the digitial I/O signals of your Matrox Iris GT to the
Matrox breakout board by following the steps in the Powering and connecting to
your Matrox Iris GT section, earlier in this appendix.
2. If generating a trigger signal, turn on output-to-trigger bypass switch 2 (SW6[2]).
This grounds the trigger signal (TRIG-).
