Connecting External Devices To Input Signals - Matrox Iris GT with MIL Manual

Connecting external devices to input signals

The following information relates to the version of Matrox Iris GT that supports
5 V auxiliary input signals. For the information pertaining to the version of
Matrox Iris GT that supports 24 V auxiliary input signals, refer to the Connecting
external devices to input signals section, in Appendix D: Using the I/O signals and
controlled-current output of Matrox Iris GT.
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 Matrox Iris GT electrical specifications
section, earlier in this appendix.
