About this Manual
This manual contains installation, configuration, and operating information for
the Extron MVX Plus 128 VGA A 12-input by 8-output wideband computer video
(VGA) and audio (A) matrix switcher.
About the MVX Plus 128 VGA A Matrix Switcher
The MVX matrix switcher distributes any of 12 inputs to any combination of
8 outputs. The matrix switcher can route multiple input/output configurations
simultaneously.
The matrix switcher is a single box solution to complex wideband video and/or
audio routing applications (figure 1-1). Each input and output is individually
isolated and buffered, and any input(s) can be switched to any one or all outputs
with virtually no crosstalk or signal noise between channels.
PRELIMINARY
1-2
MVX Plus 128 VGA A Matrix Switcher • Introduction
Figure 1-1 — Typical MVX Plus 128 VGA A matrix switcher application
The MVX Plus 128 VGA A switcher inputs and outputs VGA video on 15-pin HD
connectors and audio on 3.5 mm, 5-pole captive screw terminals.
The audio switching can either be linked with the video (audio follow) or be
independent of the video (audio breakaway). Adjustable input audio gain and
attenuation compensates for level differences between audio inputs.
The matrix switcher can be remotely controlled via its LAN port, its rear panel
RS-232/RS-422 Remote port, and its front panel Configuration (RS-232) port using
either Extron’s Windows®-based Matrix Switchers Control Program or the Simple
Instruction Set (SIS™). The SIS is a set of basic ASCII code commands that provide
simple control through a control system or PC without programming long, obscure
strings of code. SIS commands can be entered via either the Ethernet link or the
RS-232/RS-422 link.
The LAN port can be connected through a local area network (LAN) or wide area
network (WAN).
The MVX Plus 128 VGA A features e-mail notification of maintenance or other
details concerning the status of the power supplies and the loss or resumption of
sync on individual inputs to concerned personnel.
The LAN port and both serial ports can be connected to and operated from:
• A control system
• A PC
• An Extron MKP 2000 remote control panel
• An Extron MKP 3000 remote control panel
• An Extron MCP 1000 remote control panel and/or MKP 1000 remote keypad
The matrix switcher is housed in a rack-mountable, 2U high metal enclosure with
mounting flanges for a standard 19" rack. The appropriate rack mounting kit is
included with the switcher.
The switchers have an internal 100 VAC to 240 VAC, 50/60 Hz, 30 watts
autoswitchable power supply that provides worldwide power compatibility.
The MVX Plus 128 VGA A switcher has a minimum bandwidth of 300 MHz (-3 dB).
It can also switch RGBS, RGsB, RsGsBs, HDTV, component video, S-video, and
composite video.

panel for either saving or retrieving. Preset numbers larger than 20 are
accessible via serial port or Ethernet control.
Video — The switcher inputs and outputs RGBHV or RGBS (VGA) video on
15-pin HD connectors. It can also switch RGsB, RsGsBs, component/HDTV,
S-video, or composite video.
Bandwidth — The MVX Plus 128 VGA A switcher provides a minimum of
300 MHz (-3 dB) video bandwidth, fully loaded.
Audio inputs — Input and output stereo audio, balanced or unbalanced, is
provided on 3.5 mm, 5-pole captive screw terminals.
Audio input gain/attenuation — Individual input audio levels can be adjusted so
there are no noticeable volume differences between sources. You can set the
input level of audio gain or attenuation (-18 dB to +24 dB) via the Ethernet
link, either serial port, or the front panel.
Audio output volume — The audio volume of each output can be displayed and
adjusted through a range of full output to completely silent, from the front
panel or via serial port or Ethernet control.
Digital Sync Validation Processing (DSVP™) — In critical environments or
unmanned, remote locations, it may be vital to know that sources are active
and switching. Extron’s DSVP confirms that input sources are active by
scanning all sync inputs for active signals. DSVP provides instantaneous
frequency feedback for composite sync or separate horizontal and vertical
sync signals via the switchers’ serial port or LAN port. The frequency
information can be displayed on any control system or in a Windows®-based
control program on a local-area network (LAN) or Internet (IP) connection
(figure 1-2).

MVX Plus 128 VGA A Matrix Switcher • Introduction
Rooming — The switcher can be programmed to group multiple outputs to specific
switched outputs with audio follow and audio breakaway for audio models.
•Tie 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.
• Audio follow — Audio can be switched with its corresponding video input
via front panel control or under Ethernet or serial port remote control.
• Audio breakaway — Audio can be broken away from its corresponding
video signal. This feature allows any audio signal to be selected with any
video signal simultaneously to one or all outputs in any combination. Audio
breakaway switching can be done via front panel control or under Ethernet or
serial port remote control.
Operational flexibility — Operations such as input/output selection, setting of
presets, and adjustment of audio levels can be performed on the front panel
or via the Ethernet or either serial port link. The serial ports allow remote
control via a PC or a control system. The Ethernet link allows multiple
remote links with two levels of password protection.
• Front Panel Controller — The front panel controller supports input and
output selection, I/O grouping, preset creation and selection, RGB delay,
and audio gain and attenuation, and volume control (audio models). The
front panel features illuminated pushbuttons that can be labeled with text or
graphics.
• Windows-based control program — For Ethernet or serial port remote
control from a PC, the Extron Windows-based control software provides
a graphical interface and drag-and-drop/point-and-click operation. The
Windows-based control program also has an emulation mode that lets you
create a switcher configuration file at the home office and then download it
for use by the switcher on site.
• Simple Instruction Set (SIS™) — The remote control protocol uses Extron’s
SIS for easy programming and operation.
• Remote control panels and keypads — The matrix switchers are remote
controllable, using the optional MKP 2000 and MKP 3000 remote control
keypads. The remote control devices are easy to use and provide tactile
buttons for quick selection. Each MKP can be used for input-to-output
switching, one-touch switching for a particular output. The MKP 3000 also
can be used for selection of global presets.
Upgradeablefirmware — The firmware that controls all switcher operation can
be upgraded in the field via RS-232/RS-422 or Ethernet, without taking the
switcher out of service. Firmware upgrades are available for download
on the Extron Web site, www.extron.com, and can be installed using the
Windows-based control program or the built-in HTML pages.
Labeling — Extron’s included button label software lets you create labels to place
in the front panel I/O buttons, with names, alphanumeric characters, or color
bitmaps for easy and intuitive input and output selection. Alternatively,
labels can be made with any Brother™ P-Touch™ or comparable labeler.

Introduction, cont’d
Global memory presets — Input/output configurations can be stored in any
of 32 global memory presets. You can then recall those configurations,
when needed, with a few simple steps using the front panel. For the
MVX Plus 128 VGA A, 20 global memory presets are available from the front
panel; the remaining presets are available via serial port control.
Rack mounting — Rack mountable in any conventional 19" wide rack
Three front panel security lockout modes (Executive modes) — If a matrix
switcher is installed in an open area, where operation by unauthorized
personnel may be a problem, either of two security lockout modes can be
implemented (the third mode is unlocked). When a front panel locked mode
is enabled, a special button combination or SIS command is required to
unlock the front panel controller and make the front panel fully operational.
I/O grouping — This feature allows the matrix to be virtually divided into smaller
sub-switchers, making installation and control easier. I/O grouping allows
specific inputs and outputs, such as those designated for a specific purpose,
to be grouped together. I/O grouping limits the selection of inputs and
outputs to members of the same group.
Power — The matrix switcher’s 100 VAC to 240 VAC, autoswitchable, internal
power supply provides worldwide power compatibility.

Audio connections
By default, the audio ties follow the video ties. Audio breakaway, which can be
activated via the front panel or under Ethernet or serial port control, allows you
to select from any one of the audio input sources and route it separately from its
corresponding video source. See chapter 3, “Operation”, chapter 4, “Programmer’s
Guide”, chapter 5, “Matrix Software”, and chapter 6, “HTML Operation” for
details.
Connections for balanced and unbalanced audio inputs — Each input has
c
a 3.5 mm, 5-pole captive screw connector for balanced or unbalanced stereo
audio input. Connectors are included with each switcher, but you must
supply the audio cable. See figure 2-2 to wire a connector for the appropriate
input type and impedance level. Use the supplied tie-wrap to strap the audio
cable to the extended tail of the connector. High impedance is generally over
800 ohms.

PRELIMINARY
C
The length of the exposed (stripped) portion of the copper wires is
important. The ideal length is 3/16” (5 mm). Longer bare wires can
short together. Shorter bare wires are not as secure in the direct insertion
connectors and could be pulled out.
C
The captive screw audio connector can easily be inadvertently plugged
partially into one receptacle and partially into an adjacent receptacle. This
misconnection could damage the audio output circuits. Ensure that the
connector is plugged fully and only into the desired input or output.
N
See figure 2-3 to identify the tip, ring, and sleeve parts of the connector when
you are making connections for the switcher from existing audio cables. A mono
audio connector consists of a tip and sleeve. A stereo audio connector consists
of a tip, ring and sleeve. The ring, tip, and sleeve wires are also shown on the
captive screw audio connector diagrams, figure 2-2 and figure 2-4.
Figure 2-3 — Typical audio connectors
The audio level for each input can be individually set via the front panel
or Ethernet or RS-232/RS-422 control to ensure that the level on the output
does not vary from input to input. See chapter 3, “Operation”, chapter 4,
“Programmer’s Guide”, chapter 5, “Matrix Software”, and chapter 6, “HTML

the switcher from a PC that is running Extron’s Windows-based
control program or has downloaded HTML pages from the
switcher.
Ethernet connection indicators — The Link and Act LEDs
indicate the status of the Ethernet connection. The Link LED
indicates that the switcher is properly connected to an Ethernet
LAN. This LED should light steadily. The Act LED indicates
transmission of data packets on the RJ-45 connector. This LED
should flicker as the switcher communicates.

This port is independent of the rear panel Remote port and is not affected by
changes to the rear panel port’s protocol. This front panel port’s protocol can be
changed, under SIS command control only. See the Command/Response table
for IP SIS commands, in chapter 4, “Programmer’s Guide”, to configure all
ports under SIS control.
N
A front panel Configuration port connection and a rear panel Remote port
connection can both be active at the same time.
The Configuration port is RS-232 only, with its default protocols as follows:
• 9600 baud • no parity • 8 data bits
• 1 stop bit • no flow control
N
The maximum distances from the matrix switcher to the controlling device
can vary up to 200 feet (61 m). Factors such as cable gauge, baud rates,
environment, and output levels (from the switcher and the controlling device)
all affect transmission distance. Distances of about 50 feet (15 m) are typically
not a problem. In some cases the matrix switcher may be capable of serial
communications via RS-232 up to 250 feet (76 m) away.

Definitions
The following terms, which apply to Extron matrix switchers, 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 — 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. Up to 32 global
memory presets can be stored in memory. Preset locations are assigned to the
input buttons and output buttons. When a preset is retrieved from memory,
it becomes the current configuration.
The switchers have 32 presets. Up to 20 presets can be selected from the
front panel for either saving or retrieving. Preset numbers larger than 20 are
accessible via serial port or LAN port control.
Room — A subset of outputs that are logically related to each other, as
determined by the operator. The switchers support up to 10 rooms, each of
which can consist of from 1 to 16 outputs.
Room memory preset — A configuration consisting of outputs in a single room
that has been stored. When a room preset is retrieved from memory, it
becomes the current configuration.
