ATTENTION: Power supply voltage polarity is critical. Incorrect voltage polarity can
damage the power supply and the unit. The ridges on the side of the cord
(see
figure 5 ) 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.
CAUTION: May cause electric shock. The two power cord wires must be kept
separate while the power supply is plugged in. Remove power before
wiring.
NOTES: • The length of the exposed (stripped) copper wires is important. The ideal
length is 3/16 inch (5 mm). Longer bare wires can short together. Shorter
wires are not as secure in the connectors and could be pulled out.
• 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 number
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 T 568A or TIA/EIA T 568B wiring standards for all connections. RJ-45
termination with Skew-Free AV UTP cable must comply with TIA/EIA T 568 A
only.
Figure 6 on the next page details the termination of TP cables with RJ-45 connectors in
accordance with the TIA/EIA T 568A or TIA/EIA T 568B wiring standards. Use either standard
with CAT 5/5e/6 cable, but use the same standard on both ends of the cable.
Note the separate columns for input from a low resolution (composite video or S-video)
and high resolution (RGB video) MTP. Note also the power table that identifies the
unconventional signal assignment when a low resolution MTP unit is jumpered for stereo
audio.
NOTES: • Enhanced Skew-free AV 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 RGB, composite video, or S-video signals.
• The orange pair of this cable has a different length and should not be used
to transmit RGB, composite video, or S-video signals.
• If you are using the DA as part of an MTP 15HD RS (serial data) transmission
system, be aware that the DA routes the serial link one way only, from the
transmitter to the receivers.
Also, the transmitter and receiver must be jumper configured to pass the
serial link one way only (see the MTP 15HD RS Series User Guide).
