Connecting a light controller and the analog
intensity control signal
Matrox Iris GTX includes an auxiliary I/O engine, with an analog intensity
control signal (AUX_AREF_OUT7), which provides a slow changing analog
intensity (dimming) control signal from 0-10 VDC. This control signal can be
used to set the intensity for a light controller (for example, with an Advanced
Illumination inline control system or Smart Vision Lights brick light); however,
it should not be used to draw any current or drive power.
To set the intensity of the light controller using Matrox Design Assistant, chose
Physical Camera under the Cameras item of the Platform configuration dialog,
and enter a value for Intensity . See the Grab and auxiliary I/O overview section of
the Matrox Iris GTX appendix in the Matrox Design Assistant help file for more
information.
Connect the lighting controller’s intensity pin directly to the analog intensity
control pin (AUX_AREF_OUT7). The following examples show how to connect
Matrox Iris GTX to the trigger and intensity pins of your lighting controller.
