About this Manual

This manual contains installation, conﬁguration, and operating information for the Extron MVX VGA A wideband computer video (VGA) and audio matrix switchers.

About the MVX VGA A Matrix Switchers

The MVX matrix switchers distribute any input signal to any combination of outputs. The matrix switchers can route multiple input/output conﬁgurations simultaneously.

The matrix switchers are single box solutions to complex wideband (ﬁgure 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 to all outputs with virtually no crosstalk or signal noise between channels.

The MVX matrix switchers are available in a variety of matrix sizes (the matrix size is the number of inputs and outputs):

• MVX 128 VGA A (12 inputs by 8 outputs)

• MVX 168 VGA A (16 inputs by 8 outputs)

• MVX 1212 VGA A (12 inputs by 12 outputs)

• MVX 1616 VGA A (16 inputs by 16 outputs)

MVX VGA A Matrix Switchers • Introduction

The MVX A switchers input and output 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.

Each matrix switcher can be remotely controlled via 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 serial port.

Either serial 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

Features

Video — The switchers input and output RGBHV or RGBS (VGA) video on

15-pin HD connectors. They can also switch RGsB, RsGsBs, component/ HDTV, S-video, or composite video.

Bandwidth — The MVX switchers provide a minimum of 300 MHz (-3 dB) video

bandwidth, fully loaded.

Audio inputs — The switchers input and output balanced or unbalanced stereo

audio 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 front panel or via serial port control.

Audio output volume — The audio volume of each output can be displayed and

adjusted through a range of full output to complete silence, from the front panel or via serial port control.

Switching ﬂexibility — The switchers provide individually buffered, independent

matrix switched outputs with audio follow and audio breakaway.

• Tie any input to any or all outputs.

• Quick multiple tie —

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 via 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 and simultaneously tied to one or all outputs in any combination. Audio breakaway switching can be done via front panel control or via 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 either serial port. The serial ports allow remote control via a PC or a control system.

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

• Windows-based control program — For 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 and one-touch switching for a particular output. The MKP 3000 also can be used for selection of global presets.

Multiple inputs can be switched to multiple outputs

Audio connections

By default, the audio ties follow the video ties. Audio breakaway, which can be activated via the front panel or under 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”, 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 ﬁgure 2-4 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.

Figure 2-4 — Captive screw connector wiring for audio inputs

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.

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.

See ﬁgure 2-5 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 2-4 and ﬁgure 2-6.

Figure 2-5 — Typical audio connectors

The audio level for each input can be individually set via the front panel or serial port 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”, and chapter 5, “Matrix Software”, for details.

MVX VGA A Matrix Switchers • Installation

• 9600 baud • no parity • 8 data bits

• 1 stop bit • no ﬂow control

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.

A front panel Conﬁguration port connection and a rear panel Remote port

connection can both be active at the same time.

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.

Front Panel Operations

The following paragraphs detail the power-up process and then provide sample procedures for the following actions:

• Creating ties, sets of ties, and conﬁgurations

• Changing a conﬁguration

• Viewing ties, sets of ties, and conﬁgurations

• Muting and unmuting outputs

• Saving a preset

• Recalling a preset

• Viewing and adjusting the output volume

• Viewing and adjusting the input audio level

• Locking the front panel

• Performing resets from the front panel

• Reading and setting the RS-232/RS-422 Remote port settings

Front panel security lockouts

In the procedural descriptions that follow, it is assumed that the switcher is in Lock mode 0 (fully unlocked). The following two Lock modes are also available:

Power

• Lock mode 1 — All changes are locked from the front panel (except for setting Lock mode 2). Some functions can be viewed.

• Lock mode 2 — Advanced features are locked and can be viewed only. Basic functions are unlocked.

See “Setting the front panel locks (Executive modes)” on page 3-36 for a detailed list of basic and advanced functions and the procedure to set the various front panel locks.

Apply power by connecting the power cord to an AC source. When AC power is applied, the switcher performs a self-test that ﬂashes 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 conﬁguration and all presets are saved in non-volatile memory. 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 S3 Sales & Technical Support Hotline.

The switcher is shipped from the factory in Lock mode 2.

Creating a conﬁguration

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

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

2. Select to conﬁgure 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.

. Repeat steps 1 through 4 to create additional ties until the desired

conﬁguration 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 you are conﬁguring video and audio ties, the Audio LED blinks and the RGBHV LED is on after you select 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 and the output LED(s) blink.

• 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 conﬁguration (conﬁguration 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. On the MVX 128 A, up to 20 presets can be selected from the front panel to be either saved or retrieved. On all other models, all 32 presets are available from the front panel. When a preset is retrieved from memory, it becomes the current conﬁguration.

• 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 Windows-based control program. See chapter 5, “Matrix Software”, 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.

• Preset numbers greater than 20 (that are too high to be available from the front panel) are accessible via serial port control.

• Figure 3-32 shows the presets associated with the various input and output buttons for the MVX 128 VGA A. Figure 3-33 shows the presets associated with the various input and output buttons for the MVX 1212 VGA A, MVX 168 VGA A, and MVX 1616 VGA A.

Reading the displayed volume

There are 65 steps of volume attenuation, with 1 dB per step (button press), except for 0-to-1, which is 13 dB. At maximum attenuation, no input LEDs are lit, 76 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 speciﬁc input using the input audio level adjustment. (See “Viewing and adjusting the input audio level”, on page 3-25). Other than the minimum and maximum volume, the switchers indicate the volume differently, depending on number (12 or 16) of input LEDs. See the table on the next page to read the volume display for each display scheme.

For each display scheme, the input LEDs blink or light sequentially to indicate the approximate volume of the selected output. Volume is deﬁned as a percentage of the input audio signal that is applied to the output. From 0% of volume, the ﬁrst Esc (>) button press applies 5.5% of the input audio signal. From 5.5% on, each Esc (>) press applies 1.5% more of the input audio signal to the output:

• Press Esc (>) button — 5.5% + 1.5% = 7% volume

This section is a detailed description 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.

 All switcher input button conﬁgurations —The Input 1 LED continues

blinking slowly.

• Press Esc (>) button twice — 7% + 1.5% + 1.5% = 10% volume

 Switchers with 12 input buttons — The Input 1 LED blinks quickly.  Switchers with 16 input buttons — The Input 1 LED lights steadily.

• Press Esc (>) button 19 times — 10% + (19•1.5%) = 38.5% volume

 Switchers with 12 input buttons —The Input 1 through 4 LEDs light

steadily.

 Switchers with 16 input buttons — The Input 1 through 5 LEDs light

steadily and the Input 6 button blinks.

When all input LEDs are lit for any switcher model, 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 quieter).

• At minimum volume, all input LEDs are unlit and 76 dB of attenuation is applied to the output. The audio output is effectively muted.

• The ﬁrst step of volume increase causes the Input 1 LED to blink (slowly, in the case of switchers with 12 input buttons). Attenuation is reduced by 13 dB (63 dB of attenuation is applied to the output).

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

• Successive steps of volume increase cause consecutive LEDs to ﬁrst blink, then light steadily.

2. Press and hold the Reset button on the rear panel while you apply AC power

to the switcher (ﬁgure 3-64).

Figure 3-64 — Hard reset

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:

. 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.

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

3. Switch among the inputs (see “Creating a conﬁguration”, 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”, 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 3-30).

A hard reset returns the switcher to the default (factory) ﬁrmware conﬁguration.

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

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 that 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 S3 Sales & Technical Support Hotline if necessary.

Conﬁguration 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 3-45 and use one for each preset conﬁguration. Cross out all unused or inactive inputs and outputs. Use different colors for video and audio.

Worksheet example 1: System equipment

Figure 3-65 shows a worksheet for an MVX 128 A in a ﬁctional organization with the system hardware annotated. Inputs 10, 11, and 13 have no connection in this organization, so they have been crossed out on the worksheet.

Serial Ports

The switcher has two serial ports that can be connected to a host device such as a computer running the HyperTerminal utility, an RS-232 capable PDA, or a control system. These ports make serial control of the switcher possible. The serial ports are:

• The rear panel Remote (RS-232 or RS-422) port, a 9-pin D female connector

• The front panel Conﬁguration (RS-232) port, a 2.5 mm mini stereo jack The default protocol for both ports is as follows:

• 9600 baud • no parity • 8-bit

• 1 stop bit • no ﬂow control The ports can be conﬁgured to operate at the 9600, 19200, 38400, or 115200 baud

rate.

PRELIMINARY

These two ports are independent of one another. A front panel Conﬁguration

port connection and a rear panel Remote port connection can both be active at the same time.

The switcher can operate at 9600, 19200, 38400, or 115200 baud rates, but

Extron recommends leaving these ports at 9600 baud only.

Rear panel Remote port

Figure 4-1 — Remote connector pin assignments

The rear panel Remote port 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 rear panel Remote port protocol and baud rate” in chapter 3, “Operation”, to conﬁgure the rear panel Remote port from the front panel.

Figure 4-2 — Optional 9-pin TRS RS-232 cable

This port is hardwired for RS-232 only.

Host-to-Switcher Instructions

The switcher accepts SIS (Simple Instruction Set) commands through either serial port. SIS commands consist of one or more characters per command ﬁeld. They do not require any special characters to begin or end the command character sequence. Each switcher response to an SIS command ends with a carriage return and a line feed (CR/LF = ]), which signals the end of the response character string. A string is one or more characters.

Switcher-Initiated Messages

When a local event such as a front panel operation occurs, the switcher responds by sending a message to the host. The switcher-initiated messages are listed below (underlined).

the ﬁrmware version number; nnn is the part number for your switcher model. Qik

The switcher initiates the Qik message when a front panel switching operation has occurred.

Sprnn The switcher initiates the Spr message when a memory preset has been saved from

the front panel. nn is the preset number. Rprnn The switcher initiates the Rpr message when a memory preset has been recalled

from the front panel. nn is the preset number.

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 via SIS command control only. See the Command/Response table for SIS commands, later in this chapter, to conﬁgure both ports under SIS control.

]

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

Using the Command/Response Table

The command/response table begins on page 4-6. Lower-case letters are acceptable in the command ﬁeld except where indicated for the gain and attenuation commands. The table below shows the hexadecimal equivalent of each ASCII character used in the command/response table.

Matrix Switchers Control Program

The Windows-based Extron Matrix Switchers Control Program communicates with the switcher via the rear panel Remote RS-232/RS-422 port and the front panel Conﬁguration (RS-232) port to provides an easy way to set up ties and sets of ties. The program is compatible with Windows 2000 and Windows XP. Updates to these programs can be downloaded from the Extron Web site (http://www.extron.com).

Installing the software

The program is contained on the Extron Software Products CD-ROM, disk B. Install the software as follows:

• MATRIX Switcher+ Control Program

• MATRIX Switcher+ Help

• Uninstall MATRIX Switcher

The MVX switcher can support remote control via either the rear panel Remote

RS-232/RS-422 Remote port or the front panel Conﬁguration port.

Remote RS-232/RS-422 port — The port can be conﬁgured for either the RS-232 or RS-422 serial communication protocol and operate at the 9600, 19200, 38400, or 115200 baud rate. See “Selecting the rear panel Remote port protocol and baud rate” in chapter 3, “Operation”, to conﬁgure the rear panel port from the front panel.

Conﬁguration port — The port supports RS-232 serial communication protocol only. The port can operate at the 9600, 19200, 38400, or 115200 baud rate, but Extron recommends leaving this port at the 9600 baud rate. See the Serial port conﬁguration commands on page 4-11 to conﬁgure either port using an SIS command.

Using the Matrix Switcher Control 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.

utility resets the switcher (ﬁgure 5-9).

Figure 5-9 — Firmware Loader status indicator bar

10. Click the Exit button to exit the ﬁrmware loader utility.

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.

. When prompted, conﬁrm that the ﬁrmware version displayed in the ﬁrmware

loader is correct. Click OK in the Firmware Update prompt window.

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

speed up the upload process. Occasionally, the ﬁrmware 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 ﬁrmware upload completes, see “Selecting the rear panel Remote port protocol and baud rate” in chapter 3, “Operation”, on page 3-38.
