You can route each of the Matrox Iris GT auxiliary output signals to a Matrox
Iris GT auxiliary input signal. This is primarily used for testing, allowing you to
receive what was sent to 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
breakout board by following the steps in the Powering Matrox Iris GT and
connecting its I/O signals to the breakout board section.
2. For each auxiliary output signal to route to an auxiliary input, switch on an
output-to-input bypass switch. The output-to-input bypass switch box (SW8) has
4 switches, each one representing one of the four auxiliary input signals of your
Matrox Iris GT. To route Matrox Iris GT auxiliary output signal 4
(AUX(USER)_IND_OUT4) to auxiliary input signal 0
(AUX(USER)_OPTO_IN0+), turn on output-to-input bypass switch 1
(SW8[1]). Repeat for each auxiliary output signal to be re-routed to a auxiliary
input signal.
For more information on the output-to-input bypass switch box (SW8), see the
Output-to-input bypass switch box subsection of the Switch boxes section.
❖ Note that if you route auxiliary output signal 4 (AUX(USER)_IND_OUT4) to
the first Matrox Iris GT auxiliary input signal (AUX(USER)_OPTO_IN0+), you
cannot also route it to the trigger signal (TRIG_OPTO_IN+).
3. For each auxiliary output signal routed to an auxiliary input, switch on an output
pull-up resistor. The output pull-up resistor switch box (SW7) has 4 switches,
each one representing one of the four auxiliary output signals of your Matrox
Iris GT. If routing Matrox Iris GT auxiliary output signal 4
(AUX(USER)_IND_OUT4) to auxiliary input signal 0
(AUX(USER)_OPTO_IN0+), 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.
