Section 3: Connecting Devices to the Projector

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.

3.4 Connecting Devices to the GPIO Port

The GPIO port is a 37-pin D-sub connector (female) located on the PIB input panel and provides 8 input and 7

output signals for connecting external devices to the cinema projector. To configure the pins on the connector,

tap Menu > Administrator Setup > GPIO Setup.
