Figure 1-1 — Typical MVX 88 VGA A application
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 # 70-336-01).
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.
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.
Upgradeablefirmware — 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.
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” 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.
For tabletop use, affix one of the supplied self-adhesive rubber feet to each corner
of the bottom of the switcher.
Rack mounting the switcher
All of the MVX Series VGA switcher models are housed in rack-mountable, 1U
high, full rack wide metal enclosures. The appropriate rack mounting kit is
included with each switcher. Rack mount the switcher as follows:
1.If feet were previously installed on the bottom of the switcher, remove them.
2.Attach the rack mount brackets to the switcher with the eight #8 machine
screws provided (figure 2-1).
Keep the switcher out of bright light to prevent interference with the IR
signals from the IR 501 remote control.

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
User’s Guide.

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.

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.
Infrared remote sensor — This sensor receives infrared (IR) signals from the
1
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’s Guide.
Keep the switcher out of bright light to prevent interference with the IR signals
from the IR 501 remote control.
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 selected input’s
audio level has been adjusted to the –10 dBV internal reference level.
(In Audio Setup mode, the selected input’s audio is automatically tied to
output 1.) See Adjusting input audio gain and attenuation on page 3-18 and

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
•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.

Using presets
The current configuration (configuration 0) can be saved as a preset in any one of
16 preset memory addresses. Each switch 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). Preset numbers above
those available from the front panel are available under RS-232 or IR control only.
See chapter 4, Remote Operation.
•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 Extron’s
Windows-based control program. See Chapter 4, Remote Operation, for
more details.
•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.

Adjusting input audio gain and attenuation
Audio/video switchers have input audio gain and attenuation adjustments. In
Audio Setup mode the audio gain or attenuation 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 (figure 3-30).
In Audio Setup mode, whichever input is selected for adjustment is automatically
tied to output 1. You can 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 chapter 4, Remote Operation).
The input audio gain or attenuation can be adjusted from the front panel or by
using Extron’s Windows-based 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
°
•The +dB LED on indicates a positive (gain) level. The –dB LED on
indicates a negative (attenuation) level. Both LEDs on indicate 0 dB.
By noting these LEDs’ displays and counting the number of 1 dB steps
you increase or decrease the audio level (step 4 and example 8, step 2a),

Setting the output audio level
The audio level for each output can be set only via the RS-232 port, using either SIS
commands or the Windows-based control program (see chapter 4, Remote Operation).
The default settings are professional level (+4 dBu) and consumer level (–10 dBV).
The default is professional level.
The MVX Series switchers have a front panel security lockout feature (Executive
mode) that limits the operation of the switcher from the front panel and optional IR
remote control. When the switcher is locked, the Enter button, I/O button
(video, audio, or video and audio selection), and all of the front panel audio gain
and attenuation functions are disabled. The front panel input and output buttons
continue to allow ties to be viewed, but ties cannot be created.
The front panel security lockout also disables the IR remote sensor to lock out
remote control functions.
Toggle the front panel lockout on and off by pressing and holding the Enter and

Figure 3-42 — System reset to factory defaults
The current configuration, all presets, and all input audio levels are saved in nonvolatile memory within 5 seconds of a change or exiting Audio Setup mode. When
power is applied, the last current configuration is retrieved. The previous presets
remain intact.
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.
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 Audio input and output connections(audio/video models only), in chapter 2, Installation. 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 3-18) 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)
•Measure the output 1 audio level (in Audio Setup mode, the selected input
level (see the Audio output level SIS commands in chapter 4, RemoteOperation).
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.
Rather than trying to remember the configuration for each preset, use worksheets
to record this information. Make copies of the blank worksheet on page 3-31 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 3-34 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.

Figure 4-2 — Small matrix IR remote control
The RS-232 protocol is 9600 baud, 8-bit, 1 stop bit, no parity, and no flow control.
RS-232 remote control devices can be either a host device, such as a computer or a
control system.
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.
Two remote control methods are available: Extron’s Simple Instruction Set and
Extron’s Windows-based Matrix Switchers Control Program.
Operation of the IR 501 remote control is described in the IR 501 Small Matrix IRRemote Control User’s Guide.
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.
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.
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 switcherinitiated 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 2004, 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).
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.
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)

Loading firmware using an SIS command
Firmware can be uploaded two ways:
1.Using the Matrix Switchers Control Program.
2.Using the
such as HyperTerminal.
Extron recommends that you upload firmware using the Matrix
Switchers Control Program (see Update firmware on page 4-14) 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:
Esc
upload SIS command entered via a communications utility
1.Visit the Extron web site, www.extron.com, select the MVX switcher product
category, select the latest firmware file for download, and copy it to your
computer. Note the folder to which you save the firmware file.
2.Start a communications utility such as HyperTerminal. Select the Comm port
that is connected to the switcher’s RS-232 port. Use 9600 bits per second, 8
data bits, “none” parity, 1 stop bit, and “none” flow control.
If you are performing this procedure to recover from corrupted firmware, the
switcher will respond only to the “n”, “q”, and “
Esc
upload” SIS commands.
The firmware upload can
take several minutes. If
HyperTerminal’s echo
function is turned off, you
will have no indication
that the upload is
progressing. If desired,
turn on the echo function
as follows (figure 4-3):
Click File > Properties >
Settings > ASCII Setup...
and then click Ok twice.
3.Depress the keyboard’s Esc
key and then type upload.
The computer responds with
the “Go” prompt.
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 (figure 4-4).
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 4-4— Select the firmware upgrade file
7.Click Open. The firmware upload begins. If you have HyperTerminal’s echo
function turned on, HyperTerminal will display a scroll of the text of the
firmware file as it uploads to the switcher (figure 4-5).
Figure 4-5— Upload progress display
8.After several minutes, the switcher reports the startup copyright message:
(C) Copyright 2004, Extron Electronics “MVX nn VGA/A Series”, Vx.xx
This message indicates that the firmware upload is complete.
The Extron Matrix Switchers Control Program accompanies the MVX Series VGA
switchers. The program, which communicates with the switcher via the RS-232
port, provides an easy way for you to set up ties and sets of ties.
The program is compatible with Windows 95/98, Windows NT, Windows ME,
Windows 2000, and Windows XP. Updates to this program can be downloaded
from the Extron Web site (http://www.extron.com).
Installing the software
The program is contained on a set of 3.5-inch diskettes. Install the program and run
it from the hard drive.
To install the program from the floppy disk to the hard drive, run Setup.exe from
the floppy disk and follow the instructions that appear on the screen. The program
occupies approximately 3 MB (megabytes) of hard-drive space.
By default, the Windows installation creates a C:\MTRX50 directory and places two
icons (Matrix Switcher+ Control Program and Matrix Switcher+ Help) into a group
or folder named “Extron Electronics.”
The program was designed to control most Extron matrix switchers, but its
operation is limited to the features and configuration of your MVX Series
VGA switcher.
Using the software
Overview
1.To run the Matrix Switchers Control Program, double-click on the
Matrix Switcher+ Control Program icon (shown at left) in
the Extron Electronics group or folder.
The Comm Port Selection window (figure 4-6) appears.
Figure 4-6 — Comm port selection window
2.Choose either the comm port that is connected to the MVX switcher’s RS-232
port, or Emulate.
Although IP [LAN] is available for selection, the switcher does not have an
Ethernet port. Do not select IP [LAN].
4.To set up audio to follow video (audio and video have the same tie
configuration), select the Follow checkbox at the bottom of the window. To
set up audio to breakaway (audio and video have different tie configurations),
deselect the Follow checkbox.
5.To make the control program easier to use, assign a device icon to each input
and output. Click on a box that represents an input or output, and drag the
desired icon onto the box from the icon palette that appears.
6.To create a tie, drag an input box to one or more output boxes. If the Take
button is not grayed out, click the Take button.
7.To remove a single tie, drag the output box to its tied input box or to the trash
can. To remove a set of ties, drag the input box to the trash can.
The firmware upgrade utility provides a way to replace the firmware that is coded
on the switcher’s control board without taking the switcher out of service, opening
the switcher enclosure, and replacing the firmware chip.
Upgrading the firmware does not overwrite the current configuration, presets,
or the audio settings.
Update the switcher firmware as follows:
1.Visit the Extron web site, www.extron.com, select the MVX switcher product
category, select the latest firmware file for download, and copy it to your
computer. Note the folder to which you save the firmware file.
2.Start the Matrix Switchers Control Program and connect to the MVX switcher.
See Using the software in this chapter, steps 1 through 3, starting on page 4-11.
Valid firmware files must have the file extension “.S19”. Any other file
extension is not a firmware upgrade.
5.Click the Open button. A status bar, which shows the progress of the upload,
appears in the Firmware Loader window (figure 4-10). The firmware upload
to the switcher may take several minutes.
Figure 4-10 — Firmware Loader status indicator bar, switcher reset, and
firmware update
Once the status bar has progressed fully from left to right across the indicator
window, the firmware loader utility automatically resets the switcher
(figure 4-10).
If the firmward loader utility exits before the status bar has progressed
completely across the indicator window, try using a control cable with only
pins 2, 3, and 5 connected. If necessary, modify the cable by removing pins or
cutting wires.
If the firmware loader utility exits before the status bar has progressed
completely across the indicator window, the firmware may be corrupted and
may no longer respond to the Matrix Switchers Control Program. In this
condition, the firmware upload can be accomplished only by using the SIS
commands. See Loading firmware using an SIS command on page 4-9.
6.When prompted, confirm that the firmware version displayed in the firmware
loader is correct. Click Ok in the Firmware Update prompt window to exit the
firmware loader utility.
