Infrared (IR) Remote Control (part # 70-336-01).
MVX 44 / 48 / 84 / 88 VGA Matrix Switchers • Introduction1-2
Features
Video — These switchers input and output VGA – UXGA RGBHV, RGBS, RGsB,
RsGsBs video, or component/HDTV signals on 15-pin HD female connectors.
Bandwidth — Bandwidth is 300 MHz (–3 dB). This high bandwidth allows the
switchers to switch high resolution video with no loss of signal quality.
Audio input — These switchers input unbalanced stereo audio signals on 3.5 mm
mini jacks.
Audio output — These switchers output balanced or unbalanced stereo audio
signals on 3.5 mm, 5-pole captive screw terminals.
Audio input gain/attenuation — You can set the input audio gain or attenuation
(–18 dB to +10 dB) via the RS-232 port or from the front panel. Individual
input audio levels can be adjusted so there are no noticeable volume
differences between sources and for the best headroom and signal-to-noise
ratio. This function also eliminates the need for separate preamps or
attenuators when used with professional (higher line level) and consumer
(lower line level) audio equipment.
Audio output level switch — The audio level of each output can be set to either
–10 dBV (consumer level) or +4 dBu (pro level) via RS-232 control only.
Audio follow — Audio can be switched with the corresponding video input.
Audio follow switching can be done via front panel control, optional IR 501
control, or the RS-232 port.
Audio breakaway — Audio can be broken away from its corresponding video
input signal. Audio breakaway switching can be done via front panel control,
optional IR 501 control, or the RS-232 port.
Switching flexibility — Provides individually buffered, independent matrix
switched outputs with audio follow and audio breakaway for audio versions.
• Any input to any or all outputs
• Quick multiple tie — Multiple inputs can be switched to multiple outputs
simultaneously. This allows all displays (outputs) to change from source to
source at the same time.
Operational flexibility — Operations such as input/output selection and setting of
presets can be performed on the front panel, via the RS-232 port, or using the
optional IR 501 small matrix universal remote control. The RS-232 port
allows remote control via a PC or control system.
• Front panel controller — The MVX series front panel controller feature
supports touch-of-a-button input and output selection, preset creation and
selection, and audio gain and attenuation control.
• RS-232 control — The switcher’s RS-232 port allows remote control via a PC
or control system using Extron’s Simple Instruction Set
included Windows®-based control program.
• Optional IR remote control — The MVX switchers are remote controllable,
using the optional IR 501 Small Matrix IR Remote Control.
Upgradeable firmware — The firmware that controls the switcher’s operation can
be upgraded in the field via the RS-232 port, without taking the switcher out
of service, opening the switcher enclosure, and replacing the firmware chip.
Firmware upgrades are available for download on the Extron Web site,
www.extron.com, and they can be installed using the Windows-based control
program.

can then recall those configurations, when needed, with a few simple steps.
On each model, there are as many presets available from the front panel as
there are input and output buttons:
• MVX 44s have 8 presets available on the front panel
• MVX 48s and MVX 84s have 12 presets available on the front panel
• MVX 88s have 16 presets available on the front panel
On smaller MVXs, presets that are not available from the front panel are still
available under RS-232 or optional IR 501 control.
Rack mountable — With the included rack mounting kit, the switchers can be
mounted in any conventional 19” wide rack.
Under-desk mountable — With an optional desk mounting kit, the switchers can
be mounted under a desk, podium, or other furniture.
Front panel security lockout (executive mode) — If a MVX Series switcher is
installed in an open area where operation by unauthorized personnel may be
a problem, a security lock-out feature can be implemented. When the front
panel is locked, a special button combination is required to unlock the front
panel controller before it can be operated. Ties can still be viewed.
When the front panel is locked out, the switcher can still be operated via the
RS-232 link.
Power supply — The matrix switchers’ internal 100 VAC to 240 VAC, 50/60 Hz,
30 watts, auto-switchable power supply provides worldwide power
compatibility.

other furniture. Mark the location of holes for screws on the underside of the
desk.
MVX 44 / 48 / 84 / 88 VGA Matrix Switchers • Installation2-2
3. Drill 1/4" (6.4 mm) deep, 3/32" (2 mm) diameter pilot holes in the table or
desk at the marked screw locations from the underside/inside (concealed
side) of the furniture, where the switcher will be located.
4. Insert the four wood screws into the pilot holes. Fasten each screw into the
installation surface until just less than 1/4" of the screw head protrudes.
5. Align the installed screws with the slots in the mounting brackets, and place
the switcher against the surface, with the screws through the bracket slots.
6. Slide the switcher slightly forward or back, then tighten all four screws to
fasten it in place.
Cabling and Rear Panel Views
All connectors are on the rear panel. Depending on the model, the switcher can
have up to eight high resolution video and stereo audio inputs and eight video and
audio outputs.
Figure 2-2 shows a MVX 88 VGA A video and audio switcher. Other switcher
models are housed in the same 1U enclosures, but have fewer input connectors
and/or output connectors to accommodate the different matrix sizes that they
provide.

CAUTION
Connect the sleeve to ground (Gnd). Connecting the sleeve to a negative
(–) terminal will damage the audio output circuits.
Figure 2-4 shows two methods of wiring the connectors for output. A mono
audio connector consists of the tip and sleeve. A stereo audio connector
consists of the tip, ring, and sleeve. If you are wiring a captive screw
connector from an existing unbalanced audio cable, the white insulated wire is
typically the left channel (tip) and the red insulated wire is typically the right
channel (sleeve). There is no reliable standard for existing balanced audio
cables.
The audio level for each input can be individually set, via the front panel or
RS-232, to ensure that the level on the output does not vary from input to
input. See chapter 3, Operation, and chapter 4, Remote Operation, for details.
By default, the audio follows the video switch. Audio breakaway, which is
commanded via the front panel, via RS-232 control using SIS commands or
the Windows-based control program, or via optional IR 501 control, allows
you to select from any one of the audio input sources. For details, see
chapter 3, Operation, and chapter 4, Remote Operation, and refer to the IR 501

Figure 2-5 — RS-232 port pin assignment
The cable used to connect the RS-232 port to a computer or control system
may need to be modified by removing pins or cutting wires. If you encounter
problems while operating under RS-232 control (the switcher may hang up),
pins 1, 4, 6, 7, and 8 may need to be disconnected. Either cut the wire to
pins 1, 4, and 6 through 8 in a hard-shelled connector or remove pins 1, 4, and
6 through 8 from a molded plug.
See chapter 4, Remote Operation, for definitions of the SIS commands and details on
how to install and use the control software.
Using the hardwired IR input on pin 9, you can use a control system with
IR-learning capabilities to operate the switcher just as if you were using an IR 501
remote control. The control system must first “learn” the IR command from an
IR 501, after which it sends the same commands to the MVX via pin 9.

Operations
The following paragraphs detail the power-up process and then provide sample
procedures for creating ties, sets of ties, and configurations; changing a
configuration; viewing ties, sets of ties, and configurations; saving a preset;
recalling a preset; viewing and adjusting the audio level; and selecting the front
panel security lockout.
Powering up the switcher
1. Plug in the switcher. On all switcher models, power is automatically applied
when the power cord is connected to an AC source. When AC power is
applied, the switcher performs a self-test and initialization that sequences the
front panel LEDs on and off from left to right. A successful power up self-test
and initialization leaves the power LED on, the Video and Audio LEDs on,
and all other LEDs off.
The current configuration, all presets, and all input audio levels are saved in
non-volatile memory within 5 seconds of a change or exiting Audio Setup
mode. When power is applied, the most recent configuration is retrieved.
The previous presets remain intact.
If an error occurs during the self-test, the switcher locks up and does not
operate. If your switcher locks up on power-up, call the Extron S
Technical Support Hotline.
2. Plug in all system components and turn on the input devices (such as
computers or HDTV set-top boxes) and the output devices.
3. Set the input devices to output video using each device’s own operating
instructions.
4. Create a tie (see below). The selected input image should appear at the
selected output. If no image appears, see Troubleshooting on page 3-26.
Wait at least 5 seconds after changing any configuration, saving a preset, or
exiting Audio Setup mode. Before 5 seconds have elapsed, changes that you
have made may not have been saved.

Creating a set of ties
You can create a set of ties, changing the current configuration, by using the front
panel buttons. Change the current configuration as follows:
1. Select to configure video, audio, or both by pressing the I/O button as
necessary.
2. Select the desired input and output(s) by pressing the input and output
buttons.
3. Press and release the Enter button.
4. Repeat steps 1 through 3 to create additional ties until the desired
configuration is complete.
MVX 44 / 48 / 84 / 88 VGA Matrix Switchers • Operation3-6
• Only one video input and one audio input can be tied to an output.
• If a tie is made between an input and an output, and the selected output
was previously tied to another input, the older tie is broken in favor of the
newer tie.
• Output LEDs light when an input is selected to indicate current ties.
Press and release the associated output buttons to clear unwanted outputs.
• If, when you are configuring video and audio ties, the Audio LED blinks
and the Video LED is on after you have selected an input or output, the
LEDs indicate audio breakaway, meaning that the audio ties are not the
same as the video ties for that input.
• If an input with no tie is selected, only that input’s LED lights.
• As each output is selected, the associated output LED blinks to indicate a
tentative tie until you press the Enter button or the 5-second timeout
expires. LEDs for output(s) that were already tied to the input light
steadily. Outputs that are already tied can be left on, along with new
blinking selections, or toggled off by pressing the associated output
button.
• If you inadvertently press the wrong input or output button, wait
approximately 5 seconds. The input and output button selections time out
and are abandoned.
Example 1: Create a set of video and audio ties
The following steps show an example in which input 5 is tied to outputs 3, 4, and 8.
