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.

  Power 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

  The 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.
