Auxiliary Input Signal - Matrox Iris GT with MIL Manual

112 Appendix F: The Matrox breakout board
3. Press a push button to generate an auxiliary input or trigger signal. Your Matrox
breakout board has 5 push buttons (TRIG+ through INPUT 3), one for each of
the four auxiliary input signals of your Matrox Iris GT and one for the trigger
signal. See the Push buttons section, later in this appendix, for the correspondence
between the push button and the Matrox Iris GT input signals. For example, to
generate a signal that will be received by Matrox Iris GT auxiliary input signal 0
(AUX(USER)_OPTO_IN0+), press the INPUT 0 push button.
Each input signal should have only one input source. For example, when using a
push button, it should always be the only source of input for that signal, and not
have to compete with the signal from a third-party device or the re-routing of an
output signal.
4. Repeat for each Matrox Iris GT auxiliary input or trigger signal that you want to
generate.
Routing a Matrox Iris GT auxiliary output signal to a Matrox
Iris GT auxiliary input signal
You can route Matrox Iris GT auxiliary output signals 4 to 7 to Matrox Iris GT
auxiliary input signal 0 to 3, respectively. This is primarily used for testing,
allowing you to receive what was sent on the Matrox Iris GT auxiliary output
signals. To route a Matrox Iris GT auxiliary output signal to a Matrox Iris GT
auxiliary signal, perform the following:
1. Connect the power and the digital 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.
