Power connector
— An external 12 V DCpower supply is
included with the unit. Plug it into this 2-pole 3.5 mm captive
screw connector. Wire the connector as shown in figure 2-7.

CAUTION
Power supply voltage polarity is critical. Incorrect
voltage polarity can damage the power supply and
the MMX. Identify the power cord negative lead by
the ridges on the side of the cord (figure 2-7).
CAUTION
The length of the exposed (stripped) copper wires is
important. The ideal length is 0.2" (5 mm).
Longer bare wires can short together. Shorter wires
are not as secure in the captive screw connectors
and could be pulled out.
Do not tin the stripped power supply leads before
installing the captive screw connector. Tinned wires are
not as secure in the captive screw connectors and could
be pulled out.
To verify the polarity before connection, plug in the power
supply with no load and check the output with a voltmeter.
The two power cord wires must be kept separate
while the power supply is plugged in. Remove
power before wiring.
As an alternative, an Extron P/S 100 Universal 12 V DC Power
Supply, part #60-357-01, can power multiple MMXs or other
Extron 12 V DC devices, using only one AC power connector.
CAUTION
Do not daisy chain power to this unit.

TP Cable Termination
RJ-45 termination must comply with the
TIA/EIA T 568A or TIA/EIA T 568B wiring
standards for all connections. If you are using
Skew-Free™ A/V UTP cable, then you should use
the TIA/EIA T 568A standard only.
Figure 2-8 details the recommended termination of TP cables
with RJ-45 connectors in accordance with the TIA/EIA T 568A
or TIA/EIA T 568B wiring standards. You can use either
standard with CAT 5 cable, but ensure that you use the same
standard on both ends of the cable.

Figure 2-8— TP cable termination
Skew-Free A/V cable is not recommended for
Ethernet/LAN applications.
This cable is specially designed for compatibility with
Extron Twisted Pair products, wired using the
TIA/EIA 568 A standard.
The green, brown, and blue pairs of this cable have
virtually identical lengths and should be used to
transmit the RGB signals.
The orange pair of this cable has a different length and
should not
be used to transmit the RGB signals.
