120 Appendix F: The Matrox Iris GTR breakout board
Routing Matrox Iris GTR auxiliary output signal 0
and the analog intensity control signal to a lighting controller
The Matrox Iris GTR breakout board has a dedicated connector to route auxiliary
output signal 0 and the analog intensity (dimming) control signal to a lighting
controller (such as, an Advanced Illumination inline control system (ICS3), a
Smart Vision Lights Brick light, or a similar device).
To route Matrox Iris GTR auxiliary output signal 0 and the analog intensity
(dimming) control signal to a lighting controller, perform the following:
1. Connect the power and the digital I/O signals of your Matrox Iris GTR to the
Matrox Iris GTR breakout board by following the steps in the Powering and
connecting section, earlier in this appendix.
Important If your lighting controller has both an NPN and PNP pin, follow the instructions
below to connect only one of these two pins to your Matrox Iris GTR
breakout board’s ICS3 connector.
2. Perform the instructions in one of the following subsections, depending on the
type of connection to be made:
• Connecting Matrox Iris GTR auxiliary output signal 0 to a sinking lighting
controller (PNP pin).
• Connecting Matrox Iris GTR auxiliary output signal 0 to a sourcing lighting
controller (NPN pin).
If, however, you are connecting to a device in a way not mentioned in these
subsections, refer to the Connecting devices to the auxiliary output signals section,
in Chapter 2: Powering and connecting to your Matrox Iris GTR. You can still
connect the ANALOG wire-terminal to the intensity control (dimming control)
of your lighting controller.
