CPower supply voltage polarity is critical. Incorrect voltage polarity can damage the power supply and the unit. The ridges on the side of the cord (figure 2-8) identify the power cord negative lead.

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

WThe two power cord wires must be kept separate while the power supply is plugged in. Remove power before wiring.

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 connectors and could be pulled out.

NDo not tin the power supply leads before installing them in the direct insertion connector. Tinned wires are not as secure in the connectors and could be pulled out.

Use the supplied tie-wrap to strap the power cord to the extended tail of the connector.

Alternatively, an optional Extron PS 123 Universal 12 VDC Power Supply, part #60-814-01, can power multiple Extron 12 VDC devices using only one AC power connector.

TP cable termination

NRJ-45 termination with CAT 5, CAT 5e, or CAT 6 cable must comply with the TIA/EIA T568A or TIA/EIA T568B wiring standards for all connections.

RJ-45 termination with Skew-Free A/V UTP cable must comply with TIA/EIA T568A only.

Figure 2-9, on the next page, details the recommended termination of TP cables with RJ-45 connectors in accordance with the TIA/EIA T568A or TIA/EIA T568B wiring standards. You can use either standard with CAT 5/5e/6 cable, but ensure that you use the same standard on both ends of the cable.

The audio data that is carried on wire pair 3 and 6 is incompatible with the Extron TPX 88A, which cannot switch the audio, output it locally, or break it away.

Enhanced Skew- Free A/V cable is not recommended for Ethernet/LAN applications. This cable is specially designed for compatibility with Extron’s Twisted Pair products that are wired using the TIA/EIA T568A standard.

The green, brown, and blue wire pairs of this cable have virtually identical lengths and should be used to transmit the RGB signals.

The orange wire pair of this cable has a different length and should not be used to transmit the RGB signals.
