118 Appendix D: Using the I/O signals and controlled- current output of Matrox Iris GT
Connecting to an external triggering device
To connect your Matrox Iris GT to an external triggering device, connect the
ground of your Matrox Iris GT directly to the external triggering device’s ground.
Then, connect a resistor between your Matrox Iris GT and the external triggering
device. Your Matrox Iris GT takes the output signal of the external triggering
device as its input.
You can create a MIL program that will accept the trigger signal and grab an image
either on the signal’s rising or falling edge.
