Connect Devices to the SCCI Port

is used to control a limited set of projector functionality through contact closures. This table lists the control

NOTE: All SCCI inputs require a pulse input of 50ms to several seconds to operate reliably. Inputs are 5V
resistor current limited LED's inside of optocouplers.
A "Health Output" on this connector is also provided for locations that require a projector Health Output. The
output is an open-collector circuit which only draws power when the projector is deemed to be "un-healthy".
The primary use of the Projector Health Output is to ensure that patrons are not left in a dark theatre due to
projector fault. Therefore, any fault that results in the movie playback stopping should cause this circuit to
draw power and indicate an un-healthy state. The projector is always considered to be "healthy" in Standby
Mode since there is no fear of projector fault causing an impact to patrons, and there should be no patrons in
the theatre at that time.
