GPI Triggers
InfoCaster Rackmount supports serial or USB GPI triggers for controlling output. The GPI trigger type allows
you to trigger each event with an external button press. The GPI takes the voltage from a serial port pin to
close a switch and complete the circuit, triggering the selected event.

Serial port GPI triggers need to be added to the GPI list in the Configuration
Utility before they can be used in InfoCaster. See "External Triggers Tab" in
