CThe 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.

NDo 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.

NYour 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.

NThe RS-232 connector can also transmit one-way modulated infrared (IR) signals. See "Modulated IR pass through" on page 2-33.
