C
The length of the exposed (stripped) copper wires
is important. The ideal length is 3/16" (5 mm).
Longer bare wires can short together. Shorter wires
are not as secure in the connector and could be
pulled out.
N
Do not tin the power supply leads before installing in
the connector. Tinned wires are not as secure in the
connector and could be pulled out of the connector.
Use the supplied tie-wrap to strap the power cord to the
extended tail of the connector.
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 blue connector does not have the extended tail or the
included tie-wrap.
Snap the provided ferrite bead onto the DC power cable,
between the power supply and the DVI unit's connector.
RS-232 connector wiring
Figure 2-25 shows how to wire the RS-232 connector for serial
communications.
The RS-232 connector can also transmit one-way

modulated infrared (IR) signals. See "Modulated IR
pass through" on page 2-33.
