120V Wiring DiagraM With optional Built-in ViDeo proJeCtor interFaCe
Caution:
The projector must be turned off before connecting
the trigger wires to the projector. Failure to do so may damage
the controller.
Use 2-conductor 20–24 gauge wire to extend the low voltage
connection from the projector’s 5 or 12-volt screen trigger
output to the length required to reach the VPI. When extending
the low voltage connection from the projector’s screen trigger
output polarity does not matter. The red and black wires from
the VPI are interchangeable.
iMportant note:
The wall switch is ReQUIReD to make
any limit switch adjustments, eVeN if a third party control
system is used. Therefore, it is advised to wire the switch or
provide a 3-conductor connection that is accessible.
3-conductor 20-24 gauge wire can be used in place of the
supplied RJ-14 cable to connect the wall switch. Connect the
BUS terminals on the wall switch to the corresponding BUS
terminals on the splitter board.
