About the Switchers
The Extron MAV Series AV matrix switchers (figure 1-1) are a family of broadcast
quality matrix switchers that distribute any composite video or S-video input with
audio to any combination of outputs. The MAV Series switchers can route multiple
input/output ties simultaneously. The MAV Series switchers have a wide array of
input and output configurations, video formats, and audio connections.
Depending on the model, the switchers route a combination of S-video or
composite video with audio on captive screw or RCA connectors.
The MAV 88 matrix size has models without audio.

Features
Video features
S-video (SV) models — These switchers input and output NTSC 3.58, NTSC 4.43,
PAL, or SECAM S-video (luminance [Y] and chrominance [C]) signals on
4-pin female mini DIN connectors.
Composite video (V) models — These switchers input and output NTSC 3.58,
NTSC 4.43, PAL, and SECAM composite video signals on female BNC
connectors.
Bandwidth (SV and V models) — Bandwidth is 150 MHz (-3 dB). This high
bandwidth allows the switchers to switch all of the quad-standard video
formats with no loss of signal quality.
Vertical interval switching — The switcher can use a black burst (genlock) signal to
synchronize switching during the vertical interval. This ensures glitch-free
switching among multiple timed sources.

MAV 44 / 48 / 84 / 88 Matrix Switchers • Introduction

Introduction, cont’d
Audio features
Captive screw audio connector (A) models — These switchers input and output
balanced or unbalanced stereo audio signals, on 3.5 mm, 5-pole captive screw
terminals.
RCA audio connector (A RCA) models — These switchers input and output
unbalanced stereo audio signals on left and right RCA connectors.
Audio input gain/attenuation — You can set the level of audio gain or attenuation
(+10 dB to –18 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 — In audio/video switchers, 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 — In audio/video switchers, 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.

Common features
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 MAV 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 (SIS™) or the included
Windows®-based control program.

•

Optional IR remote control — The MAV switchers are remote controllable,
using the optional small matrix IR remote control.
The switcher’s IR receiver is disabled by default and must be enabled to use
the IR remote control. See the IR receiver enable SIS command in chapter 4,
“Remote Operation” to enable the IR receiver.

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. 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.

1-4

MAV 44 / 48 / 84 / 88 Matrix Switchers • Introduction

Global memory presets — 16 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:
•

MAV 44s have 8 presets available on the front panel.

•

MAV 48s and MAV 84s have 12 presets available on the front panel.

•

MAV 88s have 16 presets available on the front panel.

On smaller MAVs, 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 MAV 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,
15 watts, auto-switchable power supply provides worldwide power
compatibility.

Installation
Mounting the Switcher
Keep the switcher out of bright light to prevent interference with the IR
signals from the IR 501 remote control.

Tabletop use
For tabletop use, affix a self-adhesive rubber foot to each corner of the bottom of
the switcher.

Rack mounting the switcher
UL requirements
The following Underwriters Laboratories (UL) requirements pertain to the
installation of the matrix switcher into a rack (figure 2-1).
1.

Elevated operating ambient temperature — If installed in a closed or multiunit 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) specified by the manufacturer.

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.

Mechanical loading — Mounting of the equipment in the rack should be such
that a hazardous condition is not achieved due to uneven mechanical loading.

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.

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 (e.g.
use of power strips).

Mounting instructions
All of the MAV Series AV 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:

2-2

If feet were previously installed on the bottom of the switcher, remove them.

Attach the rack mount brackets to the switcher with the eight #8 machine
screws provided (figure 2-1).

Insert the switcher into the rack, aligning the holes in the mounting bracket
with those of the rack.

Secure the switcher to the rack using the supplied machine screws.

Furniture mounting the switcher
The MAV Series switcher models can be mounted under a table or other horizontal
surface with an optional Extron under-desk mounting kit (part #70-222-01).
1.

Secure the two table/wall mounting brackets to the switcher with the eight
machine screws provided in the kit (figure 2-1).

Hold the switcher with attached brackets against the underside of the desk or
other furniture. Mark the location of holes for screws on the underside of the
desk.

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.

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.

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.

Slide the switcher slightly forward or back, then tighten all four screws to
secure it in place.

Installation, cont’d
Cabling and Rear Panel Views
All connectors are on the rear panel. The switcher can be connected to up to eight
S-video, composite video, and/or stereo audio sources, depending on the model.
The switcher can output to up to eight S-video, composite video, and/or audio
devices.
Figure 2-2 shows a MAV 44 AV composite video and audio switcher. Figure 2-3
shows a MAV 88 SVA RCA S-video and audio switcher. All of the switchers are
housed in the same 1U enclosures, but have more or fewer input connectors to
accommodate the different configurations they provide. The two switchers shown
have all of the connector types that are available in the MAV AV product family
covered in this manual.
Some devices, such as VCRs, can be connected to both video and audio input and
output connectors of the switcher. Others, such as tape players or CD players, can
be connected only to the audio input connectors. An audio device and a separate
video device can share an input, because the switcher is capable of switching video
and audio separately (audio breakaway).

MAV 44 / 48 / 84 / 88 Matrix Switchers • Installation

Audio input and output connections (audio/video models)
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, under RS-232 control via the SIS or Windowsbased control program, or 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 Small Matrix IR Remote
Control User’s Guide.
5

Balanced or unbalanced audio input connections (captive screw audio
connector [A] models only) — Each input has a 3.5 mm, 5-pole captive screw
connector for balanced or unbalanced stereo audio input. Connectors are
included with each MAV AV captive screw connector switcher, but you must
supply the audio cable. See figure 2-4 to wire a connector for the appropriate
input type and impedance level. High impedance is generally over 5 k ohms.
Figure 2-4 shows two methods of wiring the captive screw audio connectors for
input and figure 2-6 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.

Figure 2-7 — 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, 8, and 9 may need to be disconnected. Either cut the wire to
pins 1, 4, and 6 through 9 in a hard-shelled connector or remove pins 1, 4, and
6 through 9 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.

2-6

MAV 44 / 48 / 84 / 88 Matrix Switchers • Installation

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 MAV via
pin 9.

External sync connection
The MAV switcher switches between inputs during the vertical interval period,
resulting in glitch-free video switching. The MAV switcher can use an external
signal to synchronize switching during the vertical interval. Without the external
sync locking feature, switching between inputs can result in a brief rolling (sync
loss) or a brief change in the picture size.

Sync In connector — Connect an external genlock signal to this BNC
connector for genlocking the video signal in broadcast or other sync-critical
applications.

Sync Out connector — Connect any downstream equipment that requires
genlocking to this BNC connector to route the external sync signal throughout
the system in broadcast or other sync-critical applications.

Front Panel Controls and Indicators
The number of input and output buttons and LEDs and other controls and LEDs
that are present on each MAV Series AV matrix switcher vary with the number of
inputs and outputs and whether the switcher has video only or both video and
audio. Not every switcher has every control or indicator described in this chapter.
In the following descriptions, you will find the following terms:
•

Video-only switcher — Switches S-video or composite video only and has no
audio capabilities.

•

Audio/video switcher — Switches either S-video or composite video and
audio.
Figure 3-1 shows the front panel of an 8-input, 8-output video-only switcher.
Figure 3-2 shows the front panel of a 4-input, 8-output video and audio switcher.
These examples show all of the control and indicator combinations that you may
encounter with your particular switcher.

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 — 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. Up to 16 global
memory presets can be stored in memory. The input and output buttons are
used to select the desired preset memory location to load or retrieve a preset.
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:
•

MAV 44 models have 8 presets available on the front panel.

•

MAV 48 and MAV 84 models have 12 presets available on the front
panel.

•

MAV 88 models have 16 presets available on the front panel.

On smaller MAV models, presets that are not available from the front panel
are still available under RS-232 or optional IR 501 control.

Power/audio/data LED and infrared sensor
1

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’s Guide.
The switcher’s IR receiver is disabled by default and must be enabled to use
the IR remote control. See the IR receiver enable SIS command in chapter 4,
“Remote Operation” to enable the IR receiver.
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

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 blinks 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
(audio/video models only), 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.
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 &
Technical Support Hotline.

3-6

MAV 44 / 48 / 84 / 88 Matrix Switchers • Operation

Plug in all system components and turn on the input devices (such as DVD
players, laserdisc players, VCRs, and DSS receivers) and the output devices.

Set the input devices to output video using each device’s own operating
instructions.

Create a tie (see below). The selected input image should appear at the
selected output. If no image appears, see “Troubleshooting”, on page 3-27.

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.

On audio/video switchers, select to configure video, audio, or both by
pressing the I/O button as necessary.

Select the desired input and output(s) by pressing the input and output
buttons.

Press and release the Enter button.

Repeat steps 1 through 3 to create additional ties until the desired
configuration is complete.
•

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, MAV 44 has 8 presets
(4 input buttons and 4 output buttons) available from the front panel and the
MAV 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 recalled as the
current configuration. Presets can be viewed using Extron’s Windowsbased 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 3-31).

Figure 3-31 — Audio gain and attenuation
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.
1.

Apply audio signals to all inputs to be adjusted.

Press and hold the Audio Setup (I/O) button until the Audio Setup LED
lights. Release the Audio Setup button.

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
that 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.

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).

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.
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.

3-20

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.
•

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.

Optimizing the Audio (Audio/Video Switchers)
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)”, in chapter 2, “Installation”. For best
results, wire all of the inputs and the outputs balanced when possible.

Power on the audio sources, the switcher, and the audio players.

Apply audio signals to all inputs to be optimized.

In Audio Setup mode (see “Adjusting input audio gain and attenuation”, on
page 3-19) 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.

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 chapter 4, “Remote
Operation”).

•

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 MAV Series switcher.
1.

Ensure that all devices are plugged in and powered on. The switcher is
receiving power if the power LED is lit.

Ensure an active input is selected for output on the switcher.

Ensure that the proper signal format is supplied.

Check the cabling and make corrections as necessary.

Call the Extron S3 Sales & Technical Support Hotline if necessary.

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 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 3-44 shows a worksheet for a MAV 88 AV 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 (scan converted to composite video by an Extron USP 405 signal
processor), 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
MAV 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 control program.
Operation of the IR 501 remote control is described in the IR 501 Small Matrix IR
Remote Control User’s Guide.
The switcher’s IR receiver is disabled by default and must be enabled to use
the IR remote control. See the IR receiver enable SIS command on page 4-7 to
enable the IR receiver.
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 MAV 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.

MAV 44 / 48 / 84 / 88 Matrix Switchers • Remote Operation

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 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 “MAV nn 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.

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
Firmware can be uploaded two ways:
Using the Matrix Switchers Control Program.
Using the Esc upload 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 4-15)
and reserve this SIS procedure for correcting firmware that has been
corrupted and unable to respond to the Matrix Switchers Control
Program.

1.
2.

Firmware can be loaded using SIS commands as follows:
1.

Visit the Extron web site, www.extron.com, select the MAV switcher product
category, and determine the latest firmware that is in the proper firmware set.
•

Firmware in the version 1.xx set can be replaced only by other version
1.xx firmware, with the file extension “.HEX”.

•

Firmware in the version 2.xx set can be replaced only by other version
2.xx firmware, with the file extension “.s19”.

•

The higher the version number within a firmware set, the more recent the
firmware. Choose the latest version.

Select the appropriate firmware file to 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... , click in the Echo typed
characters locally checkbox, and then click Ok twice.

Updating the firmware
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.
The MAV switcher product line has two different hardware configurations.
The two configurations operate and function identically, but their firmware is
mutually incompatible. Ensure that you identify and download the correct
firmware set (version 1.xx or 2.xx) for your switcher or the switcher will not
operate after the firmware update. Version 1.xx firmware files have the file
extension “.HEX”. Version 2.xx firmware files have the file extension “.s19”.
See steps 1 and 2, below, to identify which firmware to retrieve from the
Extron web site: www.extron.com.
Upgrading the firmware does not overwrite the current configuration, presets,
or the audio settings.
Update the switcher firmware as follows:
1.

Start the Matrix Switchers Control Program and connect to the MAV switcher.
See “Using the software”, steps 1 through 3, starting on page 4-13.

Click Help and read the firmware version. Figure 4-11 shows a sample read of
the firmware version. The most significant digit of the firmware version
listed (such as “1” in figure 4-11) identifies the firmware set.

Figure 4-11 — Determining the firmware version

Version 2.xx firmware upload — A status bar, which shows the progress of
the upload, appears in the Firmware Loader window (figure 4-14). The
firmware upload to the switcher may take several minutes.

Figure 4-14 — 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 4-14).
If the firmware 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 4-10.

Version 1.xx firmware upload — A status
window appears that shows the progress of the
download to the switcher. The firmware
download may take a few minutes. The status
window advances to 100% and then clears when the download is complete.
The switcher performs an initialization that blinks the front panel LEDs on
and off from left to right. A successful initialization leaves the power LED on,
(audio/video models only) the on and/or off selection of the Video and
Audio LEDs the same as before the download, and all other LEDs off.
Do not interrupt the download before the download status window shows the
download is 100% complete. Interrupting the download corrupts the firmware
and the switcher will not operate properly afterwards. In this condition, the
firmware upload can be accomplished only by using the SIS commands. See
