Routing Matrox Iris GTR auxiliary output signals 117
Connecting a sinking Matrox Iris GTR auxiliary output signal to a sourcing
input with a different voltage source
If connecting to a sourcing input of a third-party device which requires less than
24 V, then your Matrox Iris GTR breakout board and your third-party device
must each have their own voltage source. In addition, set the OUT_COM selector
switch (SW3) to OPEN. Then, connect the output connector (J6) to your
third-party device as follows:
