Installation, cont’d
Power input
1. Connect the captive screw connector from the supplied 12 VDC power supply into the power receptacle.
Twisted pair cable 2, pin 5 carries a 12 VDC power signal. This remote powering feature allows a single power supply, connected to the transmitter, to power both the transmitter and receiver.
CPower supply voltage polarity is critical. Incorrect voltage polarity can damage the power supply, the transmitter, and/or the receiver. Identify the ground (
) lead by the ridges on the side of the cord (see the figure below).

CThe ideal length of exposed wire in the stripping process is 3/16" (5 mm). If longer than 3/16", the exposed wires may touch, causing a short circuit. If shorter than 3/16", the wires can be easily pulled out even if tightly fastened.
Do not tin the wires. Tinned wire does not hold its shape and comes loose over time.
2. Connect the AC power cord of the power supply unit to a 110 or 220 VAC electrical source.
3. When the transmitter or receiver is getting power, either directly from the power supply or indirectly through the remote powering feature (receiver), the front panel LED lights amber.
