CAUTION
Connect the sleeve to ground (Gnd). Connecting
the sleeve to a negative (-) terminal will damage the
audio output circuits.
The length of exposed (stripped) copper wires is critical.
The ideal length is 3/16” (5 mm).
• If the stripped section of wire is longer than 3/16”, the
exposed wires may touch, causing a short circuit
between them.
• If the stripped section of wire is shorter than 3/16”,
wires can be easily pulled out even if tightly fastened
by the captive screws.
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.
Remote control connections
6
Remote connector — Connect a computer or RS-232 control
module to this female 9-pin D connector to allow remote control
using the Extron Simple Instruction Set
™
(SIS
™
) or the Extron
Universal Switcher Control Program. Alternatively, connect a
contact closure device such as an Extron remote control
Architectural Adapter Plate (AAP or MAAP). See chapter 3,
“Remote Control”, for more information.
7
Tally Power connector — This 2-pole captive screw connector
provides power to light the LEDs on Extron MMX 32 AAP
(part #70-277-01, -11, or -21) or MMX 32 MAAP (part #70-277-12,
or -22) contact closure remote control panels. Connect the 5V
and Gnd (-) 2-pole captive screw connector on the AAP or
MAAP to this connector. See chapter 3, “Remote Control”, for
more information.
Power connection

Power connector — An external 12V power 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. Use the
supplied tie-wrap to strap the power cable to the extended tail
of the connector.

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).
The length of exposed (stripped) copper wires is critical.
The ideal length is 5/16" (7 mm).
• If the stripped section of wire is longer than 5/16”, the
exposed wires may touch, causing a short circuit
between them.
• If the stripped section of wire is shorter than 5/16”,
wires can be easily pulled out even if tightly fastened
by the captive screws.
