Output-To-Input Bypass Switch Box - Matrox Iris GT with MIL Manual

136 Appendix F: The Matrox breakout board

Output-to-input bypass switch box

The output-to-input bypass switch box (SW8) allows you to route a Matrox
Iris GT auxiliary output signal to a Matrox Iris GT auxiliary input signal.
For the Matrox Iris GT output signals to be used as input signals, the respective
switch on the output pull-up resistor switch box (SW7) must be enabled. For
example, for user-defined output signal 4 (AUX(STB)_OPENC_OUT4) to be
re-routed to user-defined input signal 0 (AUX(USER)_OPTO_IN0+ signal),
switch 1 (SW7[1]) must be set to ON.
Each input signal should have only one input source. For example, when an output
signal is re-routed to an input 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 AUX(STB)_OPENC_OUT4 signal to the AUX(USER)_OPTO_IN0 signal.
2 Routes the AUX(STB)_OPENC_OUT5 signal to the AUX(USER)_OPTO_IN1 signal.
3 Routes the AUX(USER)_OPENC_OUT6 signal to the AUX(USER)_OPTO_IN2 signal.
4 Routes the AUX(USER)_OPENC_OUT7 signal to the AUX(USER)_OPTO_IN3 signal.
