Terminating shielded cable

NThe transmitter and receiver pair works with unshielded twisted pair (UTP) or shielded twisted pair (STP) cables; but, to ensure FCC Class A and CE compliance, STP cables are required.

The Tx/Rx includes four shielded RJ-45 connectors and a length of self-adhesive shielded tape that you can use to make the STP cables that connect the transmitter and receiver.

NExtron supplies the connectors and the shielded tape.

You must supply the CAT 5, 5e, 6, or 7 STP cable.

Terminate the STP cable as follows:

1. Peel back the cable shielding (figure 2-21) from the end of the cable the length of the RJ-45 connector body (approximately 7/8" [2.2 cm]) and fold it back.

Peel back shield and fold back.

Figure 2-21 — Peeling back the cable shielding

2. Cut away and discard the clear cellophane inner wrapper from the end of the cable back to the folded-over cable shielding.

Power supply wiring

N• Only one power supply is required. A single power supply connected to either unit in the pair powers both units.

•A single power supply is included with systems packaged as a pair.

•A power supply is also included with each individually-packaged transmitter.

Figure 2-24 shows how to wire the connector.

CPower 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

(figure 2-24).

To verify the polarity before connection, plug in the power supply with no load and check the output with a voltmeter.

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 (figure 2-22).

4. Cut the unused portion of the shielded tape and retain for shielding other RJ-45 connectors.

5. Feed each individual wire into the appropriate slot of the RJ-45 connector and crimp the cable in the normal manner, folding the tangs at the end of the connector over the shielded tape (figure 2-23).
