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 location due to
projector fault. Therefore, any fault that results in the content 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 in this mode.
