Push Buttons - Matrox Iris GT MIL Installation And Technical Reference

148 Appendix F: The breakout board
Push Description
button
Trig+ Opto-isolated trigger signal, positive. Note that
output-to-trigger bypass switch 2 (SW6[2]) must be set to
on; this grounds the trigger signal.
Input 0 Opto-isolated auxiliary signal 0 (input).
Input 1 Opto-isolated auxiliary signal 1 (input).
Input 2 Opto-isolated auxiliary signal 2 (input).
Input 3 Opto-isolated auxiliary signal 3 (input).

Push buttons

Each push button generates an input signal that is sent to your Matrox Iris GT
through the breakout board's smart camera connector. When you press a push
button to create an input signal, content bounce (also called chatter) might occur.
To guarantee that the created input signal is not interpreted as multiple input
pulses, set the minimum duration (debounce time) of the input or trigger pulse.
For more information, refer to the MIL online help.
For information on using the breakout board's push buttons, refer to the
Generating a Matrox Iris GT auxiliary input or trigger signal with a push button
subsection of the Routing signals to Matrox Iris GT input signals section, earlier in
this appendix.
