Connect Devices to the SCCI Port

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 cinema projector Health
Output. The output is an open-collector circuit which only draws power when the cinema projector is deemed
to be "un-healthy". The primary use of the cinema projector Health Output is to ensure that patrons are not left
in a dark theatre due to cinema 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 cinema projector is always
considered to be "healthy" in Standby Mode since there is no fear of cinema projector fault causing an impact
to patrons, and there should be no patrons in the theatre at that time.
