Set this switch up if either of the
following is true:
• The receiver being configured is the only receiver
connected to the transmitter.
• The receiver being configured is the last receiver in a
daisy-chained system.
Set the End Unit switch down on the receiver being configured

Power supply voltage polarity is critical. Incorrect
voltage polarity can damage the power supply and
the MTP. Identify the power cord negative lead by
the ridges on the side of the cord (see figure 10).
To verify the polarity before connection, plug in the power
supply with no load and check the output with a voltmeter.
W
The two power cord wires must be kept separate
while the power supply is plugged in. Remove
power before wiring.
C
The length of the exposed (stripped) copper wires
is important.
The ideal length is 3/16
inches
(5 mm)
. Longer bare wires can short together.
Shorter wires are not as secure in the direct
insertion connectors and could be pulled out.
