Making Connections
Power Supply Wiring
The figure on the right shows how to wire the power connector.
ATTENTION:
Power supply voltage polarity is critical. Incorrect voltage
polarity can damage the power supply and the MTP.
Identify the power cord negative lead by the ridges on the side of the
cord.
To verify the polarity before connection, plug in the power supply with no load
and check the output with a voltmeter.
CAUTION:
The two power cord wires must be kept separate while the power
•
supply is plugged in. Remove power before wiring.
Les deux cordons d'alimentation doivent rester séparés tant que
•
l'alimentation est branchée. Coupez l'alimentation avant de faire les
raccordements.
The length of the exposed (stripped) copper wires is
ATTENTION:
important. The ideal length is 3/16 inches (5 mm). Longer bare
wires can short together. Shorter wires are not as secure in the direct
insertion connectors and could be pulled out.
NOTE: Do 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 124 Universal 12 VDC Power Supply (part #60-1022-01) can power multiple Extron
12 VDC devices using only one AC power connector.
TP Cable Termination
NOTE: RJ-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 3
on page 8 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.
NOTES:
The audio data that may be 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 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.
