MVX 44 / 48 / 84 / 88 VGA Matrix Switchers • Introduction
1
NOTE:
The switchers can also distribute S-video and composite video with applicable
adapters.
The MVX switcher can be locally controlled from the front panel or remotely controlled
via its rear panel RS-232 serial port or an optional IR 501 Small Matrix Infrared (IR) Remote
Control (part number 70-336-01).
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 allows 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 RS-232 port of the switcher allows remote control via a PC or
control system using the Extron Simple Instruction Set (SIS™) or the included Matrix
Switchers Control Program.
•
Optional IR remote control — The MVX switchers are remote controllable, using the
optional IR 501 Small Matrix IR Remote Control.
MVX 44 / 48 / 84 / 88 VGA Matrix Switchers • Introduction
2
Upgradeable firmware — The firmware that controls the operation of the switcher can
be upgraded in the field via the RS-232 port, without taking the switcher out of service.
Firmware upgrades are available for download on the Extron website, www.extron.com,
and they can be installed using the Windows-based control program.
Global memory presets — Sixteen global memory presets are a time-saving feature that
lets you set up and store input/output configurations in advance. You 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-inch 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 an MVX Series switcher is installed
in an open area where operation by unauthorized personnel may be a problem, a security
lockout 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 internal 100 VAC to 240 VAC, 50/60 Hz 30 watts power supply
provides worldwide power compatibility.

Mounting the Switcher
CAUTION: Installation and service must be performed by authorized personnel only.
Detailed mounting instructions can be found in the “Reference Information“ section
at the end of this guide. The 1U high matrix switchers can be placed on a tabletop or
mounted on a rack shelf. Use the included hardware for rack mounting.
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 shows an MVX 88 VGA A video and audio switcher. Other switcher models are
housed in the same 1U enclosures, but have fewer input connectors, output connectors, or
both to accommodate the different matrix sizes that they provide.

Video and Audio Input Connections
a RGB video inputs — Connect the analog computer-video sources to
1
these 15-pin HD female connectors.
NOTE:
Most laptop or notebook computers have an external video port, but they
require special commands to output the video to that connector. Also,
a laptop screen shuts off once that port is activated. See the user guide
for the computer for details, or contact the Extron S3 Sales and Technical
Support Hotline for a list of common laptop keyboard commands (see
the contact numbers on the last page of this guide for the Extron office
nearest you).
Audio inputs — Connect the unbalanced stereo audio sources to these
3.5 mm mini stereo jacks for unbalanced audio input. Figure 3 shows how to
1
wire the audio plug.

NOTES: • The length of exposed wires is critical. The ideal length is 3/16 inch (5 mm).
•
If the stripped section of wire is longer than 3/16 inch, the exposed
wires may touch, causing a short circuit.
•
If the stripped section of wire is shorter than 3/16 inch, wires can be
easily pulled out even if tightly fastened by the captive screws.
• Figure 4 on the preceding page identifies the tip, ring, and sleeve. 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 the
“Operation” section and the “Remote Operation” section.
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. See the “Operation” section, the “Remote Operation” section,

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 the “Remote Operation” section 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.

Front Panel Controls and Indicators
The number of input and output buttons and LEDs that each MVX Series VGA matrix
switcher provides varies with the number of inputs and outputs.
Figure 6 shows the front panel of an 8-input, 8-output video and audio switcher. Other
switcher models have fewer input and/or output buttons to accommodate the different
matrix sizes that they provide.
Many of the buttons and LEDs on figure 6 have dual functions.

Infrared Sensor and Power/audio/data LED
a Infrared remote sensor — This sensor receives infrared (IR) signals from the optional
IR 501 small matrix universal remote control. The IR remote control must be pointed
within 30 degrees of this sensor for best results.
Operation of the IR 501 remote control is described in the IR 501 Small Matrix IR Remote
Control User Guide.
NOTE:
Keep the switcher out of bright light to prevent interference with the IR
signals from the IR 501 remote control.
b Power/data/audio LED —
•
When lit, the Power LED indicates that power is applied to the matrix switcher.
•
When blinking off and on, the Power LED indicates that an IR signal has been
received.
•
In Audio Setup mode, the Power LED also serves as an audio meter that is tied to
output 1. The LED blinks frequently when the audio level of the selected input has
been adjusted to the –10 dBV internal reference level. (In Audio Setup mode, the
audio of the selected input is automatically tied to output 1.) See “Adjusting Input
Audio Gain and Attenuation” on page 23 and “Optimizing the Audio” on
page 31.

Operations
The following paragraphs define matrix switcher terms and then 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.
Definitions
The following Extron matrix switcher terms are used throughout this manual:
Tie — An input-to-output connection
Set of ties — An input tied to two or more outputs. (An output can never be tied to more
than one input.)
Configuration — Consists of one or more ties or one or more sets of ties
Current configuration — The configuration that is currently active in the switcher (also
called configuration 0)
Global memory preset — A configuration that has been stored. Sixteen global memory
presets can be stored in memory. The input and output buttons select preset memory
locations to load or retrieve. When a preset is retrieved from memory, it becomes the current
configuration. On each model, there are as many presets available from the front panel as
there are input and output buttons:
•
The MVX 44 has 8 presets available on the front panel.
•
The MVX 48 and MVX 84 have 12 presets available on the front panel.
•
The MVX 88 has 16 presets available on the front panel.
On smaller MVX models, presets that are not available from the front panel are still
available under RS-232 or optional IR 501 control.
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.
NOTE:
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.
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 S3 Sales and Technical Support Hotline.
See the last page of this guide for the phone number in your region of the world.
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 the operating instructions for each device.
4. Create a tie (see below). The selected input image should appear at the selected output.
If no image appears, see “Troubleshooting” on page 31.
MVX 44 / 48 / 84 / 88 VGA Matrix Switchers • Operation

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 video, audio, or both to configure by pressing the I/O button as necessary.
2. Select the desired input and one or more outputs 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.
NOTES: • 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 the LED for that input 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 outputs 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
In the following example, input 5 is tied to outputs 3, 4, and 8. The example shows the front

memory addresses. Each switcher has as many presets available from the front panel as it
has input and output buttons. For example, the MVX 44 has 8 presets (4 input buttons and
4 output buttons) available from the front panel and the MVX 88 has 16 (8 input buttons
and 8 output buttons). Figure 11 on the next page identifies preset numbers available from
the front panel for each matrix size; preset numbers above those listed are available under
RS-232 or IR control only (see the “Remote Operation” section).
NOTES: • Only the audio and video ties are stored and recalled; audio gain settings are
not saved, and they do not change when a preset is recalled.
• Presets cannot be viewed from the front panel unless they are recalled as
the current configuration. Presets can be viewed using the Extron Matrix
Switchers Control Program (see the “Remote Operation” section).
• The current configuration and all presets are stored in non-volatile memory.
When power is removed and restored, the current configuration is still active
and all presets are retained.
• When a preset is recalled, it replaces the current configuration, which is lost
unless it is also stored as a preset. The recalled preset overwrites all of the
current configuration ties in favor of the preset configuration ties.
• All models have 16 presets; on models with fewer than 16 input and output
buttons, preset numbers that are too high to be available from the front
panel are still accessible under serial port or Ethernet control.

Adjusting Input Audio Gain and Attenuation
Switchers have input audio gain and attenuation adjustments. In Audio Setup mode,
the audio level of each input can be adjusted through a range of –18 dB to +10 dB. This
adjustment range ensures that there is no noticeable volume difference among sources. It
also eliminates the need for separate preamps or attenuators when used with professional
(higher line level) and consumer (lower line level) audio equipment (see figure 12).

Figure 12.Audio Gain and Attenuation
In Audio Setup mode, the input that is selected for adjustment is automatically tied to
output 1. Connect a VU meter or an audio system to output 1 to measure or monitor the
audio while you perform adjustments.
There are two ways to measure the audio level during audio setup:
•
Monitor the input audio level indicator (Power LED) on the front panel.
•
Connect a VU meter to output 1 and, if necessary, temporarily set the output 1 level
to the consumer (-10 dBV) level (see the Audio output level SIS commands in the
“Remote Operation” section).
The input audio gain or attenuation can be adjusted from the front panel or by using the
Extron Matrix Switchers Control Program or the SIS.
1. Apply audio signals to all inputs to be adjusted.
2. Press and hold the Audio Setup (I/O) button until the Audio Setup LED lights. Release
the Audio Setup button.
3. Press and release an input button to select an input. The selected input can be adjusted
and is tied to output 1 for measurement or monitoring.
a. The Output 1 through Output 3 LEDs display the approximate audio gain or
attenuation for the selected input. The +dB and –dB LEDs display the polarity
(+ [gain] or – [attenuation]).
•
•
Each Output 1 through Output 3 LED indicates a range of 6 dB when lit:
•
Output 1 LED off = 0 dB to 5 dB
•
Output 1 LED lit = 6 dB to 11 dB
•
Output 1 and 2 LED lit = 12 dB to 17 dB
•
Output 1 through Output 3 LEDs lit = 18 dB
0 – 5 db
6 – 11 db
12 – 17 db
18 db

The +dB LED on indicates a positive (gain) level. The –dB LED on indicates a
negative (attenuation) level. Both LEDs on indicate 0 dB.
MVX 44 / 48 / 84 / 88 VGA Matrix Switchers • Operation
23
By noting the status of these LEDs and counting the number of 1 dB steps you
increase or decrease the audio level (step 4 and example 8, step 2a), you can
determine the exact input gain or attenuation setting.
b. The Power LED blinks to indicate the adjusted audio level (compared to the internal
level, -10 dBV):
•
When the LED is lit most of the time, blinking off only occasionally, the level is
too high.
•
When the LED is off most of the time, blinking on (lit) only occasionally, the
level is too low.
•
When the LED blinks frequently, the level is in the proper range.
c. The < LED lights steadily when the adjustment is at the minimum level (maximum
attenuation, -18 dB). The > LED lights steadily when the adjustment is at the
maximum gain (+10 dB).
4. Press and release the < and > buttons to increase and decrease the audio level by 1 dB
or press and hold the buttons to increase or decrease the level by 3 dB per second.
The < or > LEDs flash to indicate each 1 dB level change.
NOTE:
Each time you press the < or > button, wait for the < or > LED to flash
before pushing the button again. Pressing the button too rapidly may not
increment or decrement the audio level.
5. Press and release the Audio Setup button to save the level value in memory and to exit
Audio Setup mode. The Audio Setup LED turns off.
NOTES: • After approximately 30 seconds of front panel inactivity, the switcher
saves the most recent input gain or attenuation levels and exits Audio
Setup mode.
• There is one audio gain or attenuation setting per input. The setting is
shared by the left and right audio inputs.
• The input audio gain or attenuation settings are stored in non-volatile
memory. When power is removed and restored, the audio level settings
are retained.
Example 8: Adjust the input audio gain
The following steps show an example in which an input audio level is viewed and adjusted.
The example shows the front panel indications that result from your actions.

In this example, the LEDs indicate gain in the +6 dB to +10 dB range.
If the +dB and –dB LED are both lit they indicate an input gain of 0 dB. Otherwise, you
can determine the exact gain or attenuation using the following procedure:
a. If one or more output LEDs are lit AND the +dB LED is lit, press and release the
< button repeatedly until the highest-numbered lit output LED goes out. Count the
button presses. In example 8, assume a value of +8 dB. It will take three presses of
the < button for the Output 1 LED to go out.
If one or more output LEDs are lit AND the –dB LED is lit, press and release the
> button repeatedly until the highest-numbered lit output LED goes out. Count the
button presses.
If the +dB LED is lit and NO output LEDs are lit, press and release the < button
repeatedly until the +dB and –dB LED are both lit, indicating 0 dB. Count the button
presses.
If the –dB LED is lit and NO output LEDs are lit, press and release the > button
repeatedly until the +dB and –dB LED are both lit, indicating 0 dB. Count the button
presses.
b. Return to the original audio gain setting by pressing and releasing the < or > button
(the opposite of the button you pressed in step a) the same number of steps you
pressed the opposite arrow button in step 1. In example 8, this means pressing the
> button three times.
c. Add the dB value indicated by the highest-numbered lit output LED (no output LEDs
lit and both dB LEDs lit = 0 dB) and either of the following:
•
The number of button presses from 0 dB, or
•
The number of button presses from when the highest-numbered output LED lit.
In example 8:
Output 1 LED: 6 dB
+ 2 presses:
+2 dB
8 dB
The lit +dB or –dB LED indicates the gain (+) or attenuation (–).

Press and release the < button several more times to continue to decrease the audio
level (see figure 13). Note the output LED, +dB LED, and –dB LED changes that occur
each time the < button is pressed and released.
Figure 13 shows the result of pressing the < button a total of 9 times to change the

Optimizing the Audio
Each individual input audio gain can be adjusted within a range of -18 dB to +10 dB to
eliminate noticeable volume differences between sources and to achieve the best headroom
and signal-to-noise ratio. Adjust the audio level as follows:
1. Connect audio sources to all desired inputs and connect the audio outputs to output
devices such as audio players. See “Video and Audio Input Connections” and
“Video and Audio Output Connections” in the “Installation” section. For best
results, wire all of the inputs and the outputs balanced when possible.
2. Power on the audio sources, the switcher, and the audio players.
3. Apply audio signals to all inputs to be optimized.
4. In Audio Setup mode (see “Adjusting Input Audio Gain and Attenuation,” on
page 23) select among the inputs while observing the front panel Power LED. The LED
blinks at a rate that corresponds to the highs and lows of the audio signal.
5. As necessary, adjust the audio gain of each input so that the Power LED blinks frequently
for all selected inputs. If the LED is lit most of the time, the level is probably too high; if
the LED rarely flashes, the level is too low.
As an alternative:
•
If necessary, temporarily set the output 1 level to the consumer (-10 dBV) level (see the
Audio output level SIS commands in the “Remote Operation” section).
•
Measure the output 1 audio level (in Audio Setup mode, the selected input is tied to
output 1) with test equipment, such as a VU meter, or listen to the output 1 audio with
a critical ear.
Troubleshooting
This section gives recommendations on what to do if you have problems operating the
MVX Series switcher.
1. Ensure that all devices are plugged in and powered on. The switcher is receiving power
if the power LED is lit.
2. Ensure an active input is selected for output on the switcher.
3. Ensure that the proper signal format is supplied.
4. Check the cabling and make corrections as necessary.
5. Call the Extron S3 Sales and Technical Support Hotline if necessary. See the last page of
this guide for the phone number in your region of the world.

Worksheets
Rather than trying to remember the configuration for each preset, use worksheets to record
this information. Make copies of the blank worksheet on page 35 and use one for each
preset configuration. Cross out all unused or inactive inputs and outputs. If applicable, use
different colors for video and audio.
Worksheet Example 1: System Equipment
Figure 18 shows a worksheet for an MVX 88 in a fictional organization with the system
hardware annotated. Input 6 has no connection in this organization, so it has been crossed
out on the worksheet.
Inputs include PCs, an audio CD player, cameras, and an Extron VTG 300. Output devices
include monitors, front and rear projectors, a stereo, and a VCR for recording presentations.
The VTG 300 video test generator connected to input 8 enables a video test pattern to be
sent to one, several, or all output devices for problem isolation or adjustment purposes. An
audio test tape or CD could be used in a similar manner to check out the audio components.

Remote Operation
This section describes the operation of the MVX VGA Matrix Switcher, including:
•
IR Remote Control
•
Simple Instruction Set Control
•
Matrix Switchers Control Program
SIS commands and the Matrix Switchers Control Program require a connection to the rear
panel RS-232 port by either a host device, such as a computer, or a control system (see
item d and “Remote Connection” on page 6). The serial port protocol is:
•
9600 baud
•
8-bit
•
1 stop bit
•
No parity
•
No flow control
NOTE:
When using communications software such as HyperTerminal to control the
MVX switcher, verify that the terminal emulation is set to Auto Detect or ANSI
and set flow control to None. Other settings may cause errors.
IR Remote Control
Besides the RS-232 port, the MVX VGA Series switchers can be remotely controlled using
an optional infrared Small Matrix Universal Remote Control (figure 21). Operation of the
IR 501 remote control is described in the IR 501 Small Matrix IR Remote Control User Guide.
Using the hardwired IR input on pin 9 of the RS-232 port, 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.

Simple Instruction Set Control
Host-to-Switcher Instructions
The switcher accepts SIS (Simple Instruction Set) commands through the RS-232 port. SIS
commands consist of one or more characters per command field. They do not require any
special characters to begin or end the command character sequence. Each switcher response
to an SIS command ends with a carriage return and a line feed (CR/LF = ]), which signals
the end of the response character string. A string is one or more characters.
Switcher-initiated Messages
When a local event such as a front panel operation or an IR 501 command string occurs, the
switcher responds by sending a message to the host. The switcher-initiated messages are
listed below (underlined).
The switcher does not expect a response from the host, but, for example, the host program
might request a new status.
(C) COPYRIGHT 20yy, EXTRON ELECTRONICS “MVX nn VGA/A Series”, Vx.xx]
The copyright message is initiated by the switcher when it is first powered on.
Vx.xx is the firmware version number. “nn” is the matrix size (such as 88, eight inputs by
eight outputs).
Qik]
The switcher initiates the Qik message when a front panel or IR 501 tie creation has
occurred.
Sprnn]
The switcher initiates the Spr message when a memory preset has been saved from the front
panel or under IR 501 control. “nn” is the preset number.
Rprnn]
The switcher initiates the Rpr message when a memory preset has been recalled from the
front panel or under IR 501 control. “nn” is the preset number.
Inn Audxx]
The switcher initiates the Aud message when a front panel input audio level change has
occurred. “n” is the input number and “xx” is the dB level.
Zpa]
The switcher initiates the Zpa message when a reset of all audio input levels to 0 dB has
been initiated from the front panel.
Exen]
The switcher initiates the Exe message when the front panel security lockout (executive
mode) is toggled on or off from the front panel. “n” is the executive mode status: 1 = on, 0
= off.
Vmtn 1]
The switcher initiates the Vmt message when an IR 501 remote control output video mute
command has occurred. “n” is the output number and “1” indicates the mute function is
turned on (the output is muted).
Amtn 1]
The switcher initiates the Amt message when an IR 501 remote control output audio mute
command has occurred. “n” is the output number and “1” indicates the mute function is
turned on (the output is muted).
MVX 44 / 48 / 84 / 88 VGA Matrix Switchers • Remote Operation
37
Mutn 1]
The switcher initiates the Mut message when an IR 501 remote control output video and
audio mute command has occurred. “n” is the output number and “1” indicates the mute
function is turned on (the output is muted).
Zpz]
The switcher initiates the Zpz message when an IR 501 remote control output unmute
command has occurred. All video and audio outputs are unmuted.
Switcher Error Responses
When the switcher receives an SIS command and determines that it is valid, it performs the
command and sends a response to the host device. If the switcher is unable to perform
the command because the command is invalid or contains invalid parameters, the switcher
returns an error response to the host. The error response codes are:
E01 — Invalid input channel number (out of range)
E10 — Invalid command
E11 — Invalid preset number (out of range)
E12 — Invalid output number (out of range)
E13 — Invalid value (out of range)
E14 — Invalid command for this configuration

Loading Firmware Using an SIS Command
NOTE:
Firmware can be uploaded two ways:
1. Using the Matrix Switchers Control Program.
2. Using the Eupload SIS command entered via a communications utility
such as HyperTerminal.
Extron recommends that you upload firmware using the Matrix Switchers
Control Program (see “Updating the firmware” on page 49) and reserve this
SIS procedure for correcting firmware that has been corrupted and unable to
respond to the Matrix Switchers Control Program.
Firmware can be loaded using SIS commands as follows:
1. Obtain the latest firmware file for the matrix switcher (see steps 1 through 6 of
“Updating the firmware” on page 49.
2. Start a communications utility such as HyperTerminal. Select the Comm port that is
connected to the RS-232 port of the switcher. Use 9600 bits per second, 8 data bits,
“none” parity, 1 stop bit, and “none” flow control.
NOTES: • If you are performing this procedure to recover from corrupted firmware,
the switcher will respond only to the “n”, “q”, and “Eupload” SIS
commands.
• The firmware upload can take several minutes. If the echo function of
HyperTerminal is turned off, you will have no indication that the upload
is progressing. If desired, turn on the echo function as follows (see
figure 22): Click File > Properties > Settings > ASCII Setup...,
check the Echo typed characters locally checkbox, and then
click Ok twice.
Figure 22.Turn on the Echo Function
3. Depress the <Esc> key on the keyboard and then type upload. The computer responds
with the Go prompt.
4. Click Transfer > Send text file... .
5. Click the Files of type: drop box and select All files (*.*).

6. Navigate to the folder where you saved the firmware upgrade file. Select the file (see
figure 23).
NOTE:
Ensure that the firmware upgrade is for the MVX Series AV switcher. Valid
firmware files must have the file extension “.s19”. Any other file extension
is not a firmware upgrade for your switcher.
Figure 23. Select the Firmware Upgrade File
7. Click Open. The firmware upload begins. If you have the echo function of HyperTerminal
turned on, HyperTerminal will display a scroll of the text of the firmware file as it uploads
to the switcher (see figure 24).
Figure 24. Upload Progress Display
8. After several minutes, the switcher reports the startup copyright message:
(C) Copyright 20yy, Extron Electronics “MVX nn VGA/A Series”, Vx.xx]
This message indicates that the firmware upload is complete.
9. Exit HyperTerminal.

Mounting the Switcher
The MVX switchers are housed in a rack-mountable, 1U high, metal enclosures. Included
mounting hardware lets you install the switcher in any standard 19-inch rack or into furniture.
Tabletop Use
For tabletop use, affix one of the supplied self-adhesive rubber feet to each corner of the
bottom of the switcher.
UL Rack-Mounting Guidelines
The following Underwriters Laboratories (UL) requirements pertain to the installation of the
matrix switcher into a wall or furniture.
1. Elevated operating ambient temperature — If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may be greater
than room ambient. Therefore, consider installing the equipment in an environment
compatible with the maximum ambient temperature (Tma = +122 °F, +50 °C) specified
by Extron.
2. Reduced air flow — Installation of the equipment in a rack should be such that the
amount of air flow required for safe operation of the equipment is not compromised.
3. Mechanical loading — Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
4. Circuit overloading — Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits might
have on overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
5. Reliable earthing (grounding) — Reliable earthing of rack-mounted equipment
should be maintained. Particular attention should be given to supply connections other
than direct connections to the branch circuit (such as use of power strips).
Mounting Instructions
If desired, mount the switcher in a rack or through furniture in accordance with the
directions included with the mounting kit.
