Installation
Step 1 — Mounting
Turn off or disconnect all equipment power sources and mount the MMX 32 VGA MTP as
required (rack, furniture, or tabletop mounted).
Step 2 — Connect inputs
Connect up to three video sources (RGBHV, RGBS, RGsB, RsGsBs,
component video, S-video or composite video) to the female 15-HD
connectors, inputs 1-3.
Connect audio sources to the 3.5 mm stereo jacks and wire the audio
connectors as shown at right.
Step 3 — Connect outputs
Attach the applicable output cables (video, audio, and video and audio) as below:
a. Video output 1 — Connect a display device to this female 15-pin HD connector.
b. Audio output 1 — Connect speakers to this 3.5 mm stereo jack.

Step 4 — Remote connections
a. Contact closure connectors — Connect an Extron
MMX 32 AAP or MMX 32 MAAP contact closure
remote control panel to these two 5-pole captive
screw connectors to provide control for outputs
1 and 2. Connect the 5 V and Gnd (-) 2-pole captive
screw connector on the AAP or MAAP to either of
these connectors.
b. RS-232 connector — Connect an RS-232 control module to this 3-pole captive screw
connector (see image above) to allow remote control using the Extron Simple Instruction
Set™(SIS™) or the Extron Universal Switcher Control Program.
N For full SIS commands and details of the Universal Switcher Control Program, refer to the
MMX 32 VGA MTP Users’s Guide.
Step 5 — Power
Plug the included external 12 VDC power supply into the 2-pole
captive screw connector. Wire the connector as shown at right.
Step 6 — Pre-Peaking and sync selection
Pre-Peaking — To compensate for signal loss over long cable runs, set the DIP
switch position (up = on, down = off) as shown in the table below:

Sync selection — To select either bi-level sync or tri-level sync on output 2, set the sync DIP
switch to the desired setting (up = tri-level sync, down = bi-level sync).

Front Panel Operation
Outputs 1 and 2 — For each output press the button for the desired input (1, 2 or 3). The
LED for that input lights.
N When power is applied, the LEDs light sequentially from left to right. For first time power
up, the unit’s default configuration is input 1 tied to both outputs 1 and 2, the front panel is
not locked, and all states are unmuted. Input 1 LEDs for output 1 and for output 2 are both
lit. If this is not a first time power up, then the LEDs for the last valid input selections light.
Front panel security lock out (executive mode)
Locking the front panel protects the switcher from unwanted tampering. While the switcher is
locked, the user can select inputs only through a remote device.
To lock or unlock the front panel, press the following buttons simultaneously and hold them
for at least 3 seconds:
• For output 1 press and hold input 1 button. • For output 2 press and hold input 3 button.
The front panel LEDs flash to indicate that the
front panel is locked.
System reset
To reset the switcher to its factory settings, press and hold output 1’s input 3 button while
powering up the switcher.
Audio switching
When you selecting an input, the audio and video signals from that input are routed together
to the appropriate output.
Audio breakaway is possible through the Extron Simple Instruction Set (SIS) or the Extron
Universal Switcher Control Program. When audio breakaway is active, the front panel input
LED for the audio source flashes, while the LED of the video source lights steadily.
Device Control
Output control
Momentarily short the rear panel Remote contact pin 1, 2, or 3 for the desired output to ground
to switch to that input.
Use the +5 V port when controlling the output with an MMX 32 AAP/MAAP panel.
RS-232 Control
Software control via the RS-232 connection is possible using the Extron Simple Instruction Set
(SIS) or the Extron Windows®-based control program.
The RS-232 connector on the MMX 32 VGA MTP is a 3-pole captive screw connector.
The protocol for this connector is:
• 9600 baud • 8-bit • 1 stop bit • no parity • no flow control
N For RS-232 connect transmit, receive, and ground connectors to the control system or PC.
Software control
Installation — Insert the supplied Extron DVD into DVD drive on a PC that is connected to
the MMX. The installation window opens automatically.
Select the Software tab, scroll to the Universal Switcher control program, and click on Install.
Follow the on-screen instructions to complete installation.
Startup and use — To start up the installed software, click on the desktop icon.
To use the software, refer to the MMX 32 VGA MTP Users’s Guide, available online at
www.extron.com, for details.
