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.

c. Audio/Video (RGB) output 2 — Connect an MTP U R series or other MTP receiver

to this RJ-45 UTP connector.

Wire the connector as shown at right.

Connect a projector or other RGB video

output device to the receiver, and

connect speakers for summed (L and R)

mono audio output.

d. Audio output 2 — Connect speakers

to this 5-pole, 3.5 mm captive screw

connector for balanced/unbalanced

audio and wire connector for dual mono

output as shown below.

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:

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.
