3. Peel the backing off the self-adhesive shielded aluminum
tape and wrap it around the folded-over cable shielding,
slightly overlapping the beginning of the tape
(fi gure 2-17).
Aluminum Tape
Wrap tape around folded foil shielding.
Slightly overlap.
Cut and save the excess tape
for other connectors.
Figure 2-17 — Wrapping the shielded tape
4. Cut the unused portion of the shielded tape and retain for
shielding other RJ-45 connectors.
5. Crimp the RJ-45 cable in the normal manner, folding the
tangs at the end of the connector over the shielded tape
(fi gure 2-18).

Power supply wiring
N
A power supply connected to either unit in the pair
powers both units. Only one power supply is required.
Figure 2-19 shows how to wire the connector.
C
Power supply voltage polarity is critical. Incorrect
voltage polarity can damage the power supply and
the transmitter or receiver. Identify the power cord
negative lead by the ridges on the side of the cord
(fi gure 2-19).
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.
Use the supplied tie-wrap to strap the power cord to the
extended tail of the connector.

C
The length of the exposed (stripped) copper wires is
important. With the orange power connector,
the ideal length is 0.3" (7 mm). Longer bare
wires can short together. Shorter wires are not as
secure in the connector and could be pulled out.
N
Your transmitter/receiver pair may have shipped with a
blue captive screw connector. This blue connector can be
plugged into either a blue or an orange power receptacle.
The ideal length of exposed (stripped) copper wire
for the blue connector is 0.2” (5 mm).
The blue connector does not have the extended tail or the
included tie-wrap.
N
Do not tin the power supply leads before installing in
the direct insertion connector. Tinned wires are not as
secure in the connectors and could be pulled out of the
connector.
Snap the provided ferrite bead onto the DC power cable,
between the power supply and the DVI unit’s connector.
