Switch Boxes; Output-To-Trigger Bypass Switch Box; Output Pull-Up Resistor Switch Box - Matrox Iris GT Installation And Technical Reference

S w i t c h b o x e s
The switch boxes redirect the signals of your Matrox Iris GT. There are three
switch boxes, labeled SW6 through SW8, on the breakout board. Each switch box
has 4 switches.

The output-to-trigger bypass switch box (SW6) allows you to route a Matrox
Iris GT auxiliary output signal to the Matrox Iris GT trigger signal, and allows
the trigger signal to be grounded when not from a third-party device.
