About this Manual

This manual contains installation, conﬁ guration, and operating information for the Extron MVX 128 A 12-input by 8-output wideband computer video (VGA) and audio matrix switcher.

About the MVX 128 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 conﬁ gurations simultaneously.

The matrix switcher is a single box solution to complex wideband (ﬁ gure 1-1) video and/or audio routing applications. 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.

MVX 128 A VGA Matrix Switchers • Introduction

The MVX 128 A 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 be either 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 RS-232/RS-422 port. The matrix switcher is programmed with Extron’s Simple Instruction Set 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 the RS-232/RS-422 link.

The RS-232/RS-422 port 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 ﬂ anges for standard 19” racks. The appropriate rack mounting kit is included with the switcher.

The switcher has an internal 100 VAC to 240 VAC, 50/60 Hz, 15 watts autoswitchable power supply that provides worldwide power compatibility.

The MVX 128 A has a minimum bandwidth of 300 MHz (-3 dB). The switcher can also switch RGBS, RGsB, RsGsBs, HDTV, component video, S-video, and composite video.

• 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 RS-232/RS-422 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 RS-232/RS-422 remote control.

Operational ﬂ exibility — Operations such as input/output selection, setting of

presets, and adjustment of audio levels can be performed on the front panel or via the RS-232/RS-422 link. The RS-232/RS-422 links allow remote control via a PC or control system.

• Front Panel Controller — The front panel controller supports input and output selection, preset creation and selection, and audio gain and attenuation and volume control (audio models). The front panel features slots for labels that can identify each input and output with text or graphics.

• Windows-based control program — For RS-232/RS-422 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 conﬁ guration ﬁ le at the home ofﬁ ce 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.

Upgradeable ﬁ rmware — The ﬁ rmware that controls all switcher operation can be

upgraded in the ﬁ eld via RS-232/RS-422, 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.

Labeling — The Extron label software ships with every Extron matrix switcher.

You can create labels to place above the front panel input buttons and below the output buttons, with names, alphanumeric characters, or color bitmaps for easy and intuitive input and output selection. Alternatively, labels can be made with any Brother

Global memory presets — 32 global memory presets are a time-saving feature that

lets you set up and store input/output conﬁ gurations in advance. 20 global memory presets are available from the front panel. You can then recall those conﬁ gurations, when needed, with a few simple steps.

Rack mounting — Rack mountable in any conventional 19” wide rack.

Front panel security lockout (Executive mode) — If a matrix 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 or SIS command is required to unlock the front panel controller before it can be operated.

Power — The matrix switcher’s 100 VAC to 240 VAC, autoswitchable, internal

power supply provides worldwide power compatibility.

Video connections

The matrix switcher does not alter the video signal in any way. The signal

output by the switcher is in the same format as the input.

The MVX 128 A can also switch RGBS, RGsB, RsGsBs, component video, S-

video, or composite video by using the appropriate adapters.

RGB video inputs — Connect the analog computer-video sources to these

15-pin HD female connectors.

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’s screen shuts off once that port is activated. See the computer’s user’s guide for details, or contact Extron for a list of common laptop keyboard commands.

RGB video outputs — Connect RGBHV video displays to these 15-pin HD

female connectors for each output.

Audio connections

By default, the audio ties follow the video ties. Audio breakaway, which can be activated via the front panel or under RS-232/RS-422 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, and chapter 5, Matrix Software for details.

Connections for balanced and unbalanced audio inputs — Each input has

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 ﬁ gure 2-2 to wire a connector for the appropriate input type and impedance level. High impedance is generally over 800 ohms.

Power

Apply power by connecting the power cord to an AC source. When AC power is applied, the switcher performs a self-test that ﬂ ashes the front panel LEDs and then turns them off. An error-free power up self-test sequence leaves the RGBHV LED and the Audio LED on, and all other LEDs unlit.

The current conﬁ guration and all presets are saved in non-volatile memory. When power is applied, the most recent conﬁ guration 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 Hotline.

Creating a conﬁ guration

The current conﬁ guration can be changed using the front panel buttons. Change the current conﬁ guration as follows:

1. Press the Esc button to clear any input LEDs, output LEDs, or control LEDs that are lit.

2. Select to conﬁ gure video, audio, or both by pressing the RGBHV button and/or Audio button.

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

To indicate potential ties, output LEDs blink when an output is selected but

not tied to the input.

To indicate current ties, output LEDs light steadily when an input is tied to

the output.

To clear unwanted outputs, press and release the output buttons associated

with the lit LEDs. To indicate potential unties, output LEDs blink when an output is deselected but not untied from the input.

4. Press and release the Enter button to accept the new tie or to break an existing tie.

5. Repeat steps 1 through 4 to create additional ties until the desired conﬁ guration is complete.

N • 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.

• To indicate current ties, output LEDs light when an input is selected. To clear unwanted outputs, press and release the associated output buttons.

• If, when conﬁ guring video and audio ties, the Audio LED blinks and the RGBHV LED is on after selecting 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.

• When the RGBHV and Audio LEDs are on, if an input with an audio tie but no video tie is selected, the input’s LED lights and the Audio LED blinks.

• As each output is selected, the associated output LED blinks to indicate a tentative tie. 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.

Using global presets

The current conﬁ guration (conﬁ guration 0) can be saved as a preset in any one of 32 preset memory addresses. Preset locations are assigned to the input buttons and output buttons. Up to 20 presets can be selected from the front panel to be either saved or retrieved. When a preset is retrieved from memory, it becomes the current conﬁ guration.

N • 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 conﬁ guration. Presets can be viewed using Extron’s Windows-based control program. See Chapter 5, Matrix Software, for more details.

• The current conﬁ guration and all presets are stored in non-volatile memory. When power is removed and restored, the current conﬁ guration is still active and all presets are retained.

• When a preset is recalled, it replaces the current conﬁ guration, which is lost unless it is also stored as a preset. The recalled preset overwrites all of the current conﬁ guration ties in favor of the preset conﬁ guration ties.

• Preset numbers greater than 20 (that are too high to be available from the front panel) are still accessible under RS-232/RS-422 control.

Reading the displayed volume

This section is a detailed

look at reading the output volume display on the matrix switcher’s front panel. If you do not need to read the exact value of the volume setting, skip this section.

There are 65 steps of volume attenuation, with 1 dB per step (button push), except for 0-to-1, which is 35 dB. At maximum attenuation, no input LEDs are lit, 98 dB of attenuation is applied, and the audio output is effectively muted. At no attenuation, all input LEDs are lit and the output volume is equal to the input signal plus any gain or attenuation that is applied to that speciﬁ c input using the input audio level adjustment. See Viewing and adjusting the input audio level, on page 3-24 See the table at right to read the volume display.

The input LEDs blink or light sequentially to indicate the approximate volume of the selected output. Volume is deﬁ ned as a percentage of the input audio signal that is applied to the output. From 0% of volume, the ﬁ rst Esc (

Operation, cont’d

When all input LEDs are lit, the audio output is 100% of the audio input level.

Another way to view the volume level is to think in terms of the attenuation that is applied to the output. Attenuation reduction is indicated by the lit or blinking input LEDs: when fewer input LEDs are lit, attenuation is greater (and the volume is less).

• At minimum volume, all input LEDs are unlit and 98 dB of attenuation is applied to the output. The audio output is effectively muted.

• The ﬁ rst step of volume increase causes the Input 1 LED to blink slowly. Attenuation is reduced by 35 dB (63 dB of attenuation is applied to the output). There is no change in the volume indication.

• The second step of volume increase reduces the attenuation by an additional 1 dB (62 dB of attenuation is applied to the output). The front panel display is unchanged.

• Successive steps of volume increase cause consecutive input LEDs to ﬁ rst blink slowly, then quickly, and then light steadily.

For example: When lit steadily, the Input 3 LED indicates 47 dB of attenuation

when compared to the Input 3 LED blinking quickly (48 dB to 50 dB of attenuation). The blinking Input 4 LED (45 dB to 46 dB of attenuation) is at least 2 dB less than the fast blinking Input 3 LED (48 dB – 46 dB) and at most 5 dB less (50 dB – 45 dB).

See the table on page 3-29 to read the volume display.

A hard reset returns the switcher to the default (factory) ﬁ rmware conﬁ guration.

The switcher continues to operate using this ﬁ rmware until you either cycle power, in which case the switcher begins to use the most-recently installed ﬁ rmware update, or install a new ﬁ rmware update.

Optimizing the Audio

Each individual input audio level can be adjusted within a range of -18 dB to +24 dB, so there are no noticeable volume differences between sources and for the best headroom and signal-to-noise ratio. Adjust the audio gain and attenuation as follows:

1. Connect audio sources to all desired inputs and connect the audio outputs

to output devices such as audio players. See Audio connections, in chapter 2, Installation. For best results, wire all of the inputs and the outputs as balanced.

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

3. Switch among the inputs (see Creating a conﬁ guration, on page 3-8), listening

to the audio with a critical ear or measuring the output audio level with test equipment, such as a VU meter.

4. As necessary, adjust the input audio level of each input (see Viewing and adjusting the input audio level, on page 3-24) so that the approximate output

level is the same for all selected inputs.

5. As necessary, adjust the output audio level of each input (see Viewing and adjusting the output volume, on page 3-28).

Troubleshooting

This section gives recommendations on what to do if you have problems operating the switcher and describes an actual image problem that Extron has encountered.

1. Ensure that all devices are plugged in and powered on. The switcher is receiving power if one of the front panel I/O LEDs is lit.

2. Check to see if one or more outputs are muted.

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

4. Ensure that the proper signal format is supplied.

5. Check the cabling and make corrections as necessary.

6. Call the Extron S

The default protocol is as follows:

• 9600 baud • no parity • 8-bit

• 1 stop bit • no ﬂ ow control

The MVX 128 A switcher can support either RS-232 or RS-422 serial

communication protocol, and can operate at 9600, 19200, 38400, or 115200 baud rates. See Selecting the RS-232/RS-422 protocol and baud rate on page 3-33, Operation, to conﬁ gure the RS-232/RS-422 port from the front panel.

Host-to-Switcher Instructions

The switcher accepts SIS (Simple Instruction Set) commands through the RS-232/RS-422 port. SIS commands consist of one or more characters per command ﬁ eld. 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 occurs, the switcher responds by sending a message to the host. The switcher-initiated messages are listed below (underlined).

The switcher initiates the copyright message when it is ﬁ rst powered on. Vx.xx is the ﬁ rmware version number.

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 (too large) E10 — Invalid command E11 — Invalid preset number (too large) E12 — Invalid output number (too large) E13 — Invalid value (out of range) E14 — Illegal command for this conﬁ guration E17 — Timeout (caused only by direct write of global presets) E22 — Busy

• Commands can be entered back-to-back, with no spaces. For example: 1*1!02*02&003*003%4*8$.

The quick multiple tie and tie input to all output commands activate all I/O switches simultaneously.

•

The matrix switchers support 1-, 2-, and 3-digit numeric entries (1*1, 02*02, or 001*001).

Matrix Software

Matrix Switchers Control Program

Button Label Generator Program

PRELIMINARY

Matrix Software

Two software programs accompany the MVX 128 A switcher:

• The Extron Matrix Switcher Control Program, which communicates with the switcher via the RS-232/RS-422 port, provides an easy way to set up ties and sets of ties.

• The Extron Button-Label Generator, which allows you to design and print labels for the MVX 128 A front panel buttons.

Both programs are compatible with Windows 95/98, Windows NT, Windows ME, Windows 2000, and Windows XP. Updates to these programs can be downloaded from the Extron Web site (http://www.extron.com).

Matrix Switchers Control Program

Installing the software

The program is contained on a CD-ROM and available on the Extron Web site: www.extron.com. Load and run the program from the hard drive.

To install the program from the CD-ROM to the hard drive, run Setup.exe from the CD-ROM and follow the instructions that appear on the screen. The program occupies approximately 1 MB (megabyte) 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”.

PRELIMINARY

The program was designed to control most Extron matrix switchers, but its

operation is limited to the features and conﬁ guration of your switcher.

The MVX 128 A switcher can support either RS-232 or RS-422 serial

communication protocol, and operate at 9600, 19200, 38400, or 115200 baud rates. See Selecting the RS-232/RS-422 protocol and baud rate on page 3-33, to conﬁ gure the RS-232/RS-422 port from the front panel.

5-2

MVX 128 A VGA Matrix Switchers • Matrix Software

Using the software

Many items found in the Matrix Switcher Control Program are also accessible via front panel controls (see chapter 3, Operation) and under SIS control (see chapter 4, Programmer’s Guide). The Matrix Switcher+ Help Program provides information on settings and on how to use the control program itself.

1. To run the Matrix Switcher Control Program, double-click on the Matrix Switcher Control Program icon (shown at right) in the Extron Electronics group or folder.

The Comm Port Selection window (ﬁ gure 5-1) appears.

Figure 5-1 — Comm port selection window

2. Choose either the comm port that is connected to the MVX 128 A switcher’s RS-232/RS-422 port or Emulate.

Although IP [LAN] is available for selection, the switcher does not have an

Ethernet port. Do not select IP [LAN].

 If you selected a comm port, check the baud rate displayed in the comm

port selection window. If you need to change the baud rate, click on the Baud button and double-click on the desired baud rate.

Available rates are 9600, 19200, 38400, and 115200. The default is 9600.

See Selecting the RS-232/RS-422 protocol and baud rate in chapter 3,

Operation on page 3-33, to identify the selected baud rate from the front panel.

Click OK and proceed to step 3.

 If you selected Emulate, click OK and see Using emulation mode on

page 5-10.

• To set up audio in follow mode (audio and video have the same tie conﬁ guration), select the Follow box at the bottom of the window. To set up audio in breakaway mode (audio and video have different tie conﬁ gurations), deselect the Follow box.

• 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.

• To create a tie, drag an input box to one or more output boxes. To remove a tie, drag the output box to its tied input box or to the trash can.

• For quick display of information on a speciﬁ c input or output device, position the cursor over that device in the control program window. The program opens a window that details the connections to that device, the audio level, the RGB delay, and the frequency of the video signal input from or output to that device. See the inset box in ﬁ gure 5-3.

Updating ﬁ rmware

The ﬁ rmware upgrade utility provides a way to replace the ﬁ rmware that is coded on the switcher’s control board without taking the switcher out of service and replacing the ﬁ rmware IC chip.

Update the switcher ﬁ rmware as follows:

1. Visit the Extron web site, www.extron.com, select the CrossPoint/MAV Plus product category, and select the latest ﬁ rmware install package (*.exe ﬁ le) for download. Note the folder to which you save the ﬁ rmware ﬁ le.

2. Run the executable (*.exe) ﬁ le to decompress the ﬁ rmware ﬁ le.

3. Start the Matrix Switcher Control Program and connect to the MVX 128 A

switcher. See Using the software in this chapter, steps 1 through 4, starting on page 5-3.

4. Click Tools > Update ﬁ rmware. The open ﬁ le window appears (ﬁ gure 5-4).

The ﬁ rmware loader utility increases the serial port’s baud rate to 115,200 to

speed up the upload process. Occasionally, the ﬁ rmware loader may be unable to return the serial port to its earlier baud rate, in which case communications with the switcher may not be possible. If you are no longer able to communicate with the switcher after the ﬁ rmware upload completes, see Selecting the RS-232/RS-422 protocol and baud rate in chapter 3, Operation, on page 3-33.
