Connecting external devices to input signals

You can connect a wide variety of external devices to the input signals of your
Matrox Iris GT, such as external triggering devices. For information on the
electrical specifications of the ON and OFF voltage levels, see the Electrical
specifications subsection of the Matrox Iris GT specifications section, in
Appendix B: Technical Reference.
Connect TRIG_OPTO_IN0+ to the positive (+) trigger connector of your trigger
generator.
❖ Note that in all cases, your Matrox Iris GT auxiliary input and trigger signals
expect to have a nominal voltage of 15 to 24 V.
In addition, connect the TRIG_OPTO_IN0- to the ground of the third party
device. In this case, the trigger connection is reliant on the ground of the trigger
generator, rather than the ground of your Matrox Iris GT. This results in your
Matrox Iris GT and your trigger generator to each maintain its independent
ground, and allows the connection with the trigger generator to be fully isolated.
