Connect devices to the SCCI port
The Simple Contact Closure Port (SCCI) port is a DB-9 (male) connector located on the PIB input
panel. The SCCI port controls a limited set of projector functionality through contact closures. This
table lists the control functions available through the SCCI port:

All SCCI inputs require a pulse input of 50ms to several seconds to operate reliably. Inputs are 5V
resistor current limited LEDs inside of optocouplers.
The open-collector Health Output (PIN 8) circuit only draws power when a failure occurs or an
interlock is activated.
