108 Appendix F: The Matrox Iris GTR breakout board
Routing an output signal from a third-party device to an
auxiliary input signal of your Matrox Iris GTR
To route an output signal from a third-party device to a Matrox Iris GTR auxiliary
input signal, connect the device to the input connector of the Matrox Iris GTR
breakout board. The Matrox Iris GTR breakout board can generate either a
common return path or voltage source for the auxiliary input signals.
To route a sinking or sourcing output signal from a third-party device to a Matrox
Iris GTR auxiliary input signal through your Matrox Iris GTR breakout board,
perform the following:
1. Connect the power and the digital I/O signals of your Matrox Iris GTR to your
Matrox Iris GTR breakout board by following the steps in the Powering and
connecting section, earlier in this appendix.
❖
Note that your Matrox Iris GTR breakout board expects the output signal from
any third-party device to have a nominal voltage of 24 V. For more specific
requirements, refer to Electrical specifications subsection in
Appendix B: Technical reference.
2. Perform the instructions in one of the following subsections, depending on the
type of connection to be made:
• Connecting a sourcing output device to a Matrox Iris GTR auxiliary input signal.
• Connecting a sinking output device to a Matrox Iris GTR auxiliary input signal.
If, however, you are connecting to a device in a way not mentioned in these
subsections, refer to the Connecting devices to the auxiliary input signals section, in
Chapter 2: Powering and connecting to your Matrox Iris GTR.
