Output-To-Trigger Bypass Switch Box; Output Pull-Up Resistor Switch Box - Matrox Iris GT with MIL Manual

Output-to-trigger bypass switch box

The output-to-trigger bypass switch box (SW6) allows you to route a Matrox
Iris GT auxiliary output signal to the Matrox Iris GT trigger signal, and allows
the trigger signal to be grounded when not from a third-party device.
Each trigger signal should have only one input source. For example, when an
output signal is re-routed to a trigger signal, 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 a push button.
Switch Description (ON)
1 Routes the Matrox Iris GT AUX(STB)_OPENC_OUT4 signal to the TRIG_OPTO_IN0+ signal.
2 Grounds the Matrox Iris GT TRIG_OPTO_IN0- signal. Note that this must be turned on when
using the trigger push button (Trig+), or when switch 1 of this switch box (SW6[1]) is on;
otherwise, by default, the negative opto-isolated trigger signal is floating (that is, it is not
connected to ground).
3 Reserved.
4 Diagnostic switch. Set this switch to OFF unless otherwise directed by technical support. If this
switch is ON, your Matrox Iris GT will not finish booting until it receives a CRLF through the
serial port.

Output pull-up resistor switch box

The output pull-up resistor switch box (SW7) is used when routing a Matrox
Iris GT auxiliary output signal to a Matrox Iris GT auxiliary or trigger input
signal. It also can be used when routing a signal to a third-party device.
Switch Description (ON)
1 Adds an on-board pull-up resistor to the AUX(STB)_OPENC_OUT4 signal.
2 Adds an on-board pull-up resistor to the AUX(STB)_OPENC_OUT5 signal.
3 Adds an on-board pull-up resistor to the AUX(USER)_OPENC_OUT6 signal.
4 Adds an on-board pull-up resistor to the AUX(USER)_OPENC_OUT7 signal.
