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.
Your Matrox Iris GT auxiliary input and trigger signals can have a 5 V, 12 V, or
24 V power source. For information regarding the electric specifications regarding
the ON and OFF voltage levels, see the Electrical specifications subsection of the
Matrox Iris GT specifications section, in Appendix B: Technical Reference.
