INSTALLATION INSTRUCTIONS FOR
Video Projector Interface
Video Projector Interface Installation
The Video Projector Interface (VPI) housing is divided into three compartments. The compartment labeled “Low Voltage Connections”
is where you will connect the VPI to the projector’s output and wall switch wire connections. The compartment labeled “AC Power
Connections” is where the main power and motor wire connections are made. Access is not required to the center compartment.
WARNING: To prevent electrical shock or damage to the
Video Projector Interface (VPI), do not apply power to the
VPI until all connections are complete. Make sure power
is turned off on all circuits before making connections.
CAUTION: any item being connected to the VPI cannot
be energized.
Low Voltage Connection
CAUTION: The projector must be turned off before
connecting the trigger wires to the projector. Failure to
do so may damage the controller.
2. Connect the wires from the VPI that are labeled “Low Voltage
Connection” to the end of the extended screen trigger
wires above. See Figure 1.
1. 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, be sure to maintain the proper polarity.
the red wire from the VPI is the “signal” and the black wire
from the VPI is the “ground”.
120V
CAUTION: Never apply voltage to the projector’s screen
trigger wires or the VPI and/or projector will be damaged.
