Connecting to the auxiliary I/O interface 41
Connecting an auxiliary output signal to a sourcing input
Connect a Matrox Iris GTR auxiliary output signal to a sourcing input, as shown
below.
❖ Note that, when connecting a resistive load sourcing device instead of an input
sensing sourcing device, the same connection would be used as displayed above.
Equivalent circuit only
Optional because the auxiliary output signals are optically isolated.
Up to 24V
