134 Appendix F: The breakout board
Routing one Matrox Iris GT auxiliary output signal to the Matrox
Iris GT trigger signal
You can route Matrox Iris GT auxiliary output signal 4
(AUX(STB)_OPENC_OUT4) to the Matrox Iris GT trigger signal
(TRIG_O), using the output-to-trigger bypass switch box (SW6). 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. Turn on output-to-trigger bypass switch 1 (SW6[1]).
❖
Note that if you route auxiliary output signal 4 (AUX(STB)_OPENC_OUT4)
to the trigger signal (TRIG_), you cannot also route it to the first
Matrox Iris GT auxiliary input signal (AUX(USER)_O).
In addition, if you route auxiliary output signal 4 (AUX(STB)_OPENC_OUT4)
to auxiliary input signal 0 (AUX(USER)_O), you cannot also
generate a trigger signal using the TRIG+ button on the breakout board.
3. Turn on output-to-trigger bypass switch 2 (SW6[2]). This grounds the Matrox
Iris GT TRIG_OPTO_IN- signal.
For more information on the output-to-trigger bypass switch box (SW6), see
Output-to-trigger bypass switch box subsection of the Switch boxes section.
4. Turn on output pull-up resistor switch 1 (SW7[1]).
For more information on the output pull-up resistor switch box (SW7), see the
Output pull-up resistor switch box subsection of the Switch boxes section.
