Introduction 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 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.
Introduction, cont’d 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.
Upgradeable firmware — The firmware that controls all switcher operation can be upgraded in the field via either serial port, 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 button label software ships with every Extron matrix switcher.

Matrix Software 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).
4. Follow the on-screen instructions.
Matrix Software, cont’d 2. Choose either the comm port that is connected to the switcher’s serial port or Emulate. N 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.
• To set up audio in Follow mode (audio and video have the same tie configuration), select the Follow checkbox at the bottom of the window. To set up audio in breakaway mode (audio and video have different tie configurations), deselect the Follow checkbox. • 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.
Matrix Software, cont’d Updating 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 and replacing the firmware IC chip. Update the switcher firmware as follows: Visit the Extron Web site, www.extron.com, click the Download Center tab, and then click the Firmware link (figure 5-6). PRELIMINARY 1. Figure 5-6 — Location of firmware upgrade files 2.
PRELIMINARY Folder where firmware is installed.
Matrix Software, cont’d 3. Connect a Windows-based computer to either switcher serial port or the switcher LAN port. See chapter 2, “Installation”, for more details. 4. Start the Matrix Switcher Control Program and connect to the matrix switcher. See “Using the Matrix Switcher Control software” in this chapter, steps 1 through 4, starting on page 5-3. 5. Click Tools > Update firmware. The Extron Firmware Loader utility appears (figure 5-8).
8. Click the Upload button. A status bar, which shows the progress of the upload, appears in the Firmware Loader window (figure 5-9). The firmware upload to the switcher may take several minutes. Once the status bar has progressed fully from left to right, the firmware loader utility resets the switcher (figure 5-9). N 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.
Matrix Software, cont’d Windows buttons, drop boxes, and trash can The buttons, drop boxes, and trash can on the right side of the program window perform the following functions: Power — Unavailable for MVX VGA A switchers, because the switcher power cannot be controlled via software. Executive Mode — Allows you to lock out front panel operations, except for the view-only mode functions.
Tools menu Assign device icons — Displays the complete set of input and output device icons. You can drag any of these icons to the input and output boxes. Edit device palette — Allows you to add your own device icon graphics. Audio-Input gain settings — Displays the audio gain level setting for a single input or for all inputs and allows you to change it. The level is expressed as the magnitude (number of decibels) and polarity (positive [gain] or negative [attenuation]) of the audio adjustment.
Matrix Software, cont’d Initialize — Initializes and clears any or all of the following: ties, presets, audio configuration, preset names, icon names, and icons. Preferences menu Immediate changes — Causes configuration changes to take effect immediately. Hold/verify changes — Delays implementation of configuration changes until the Changes – Take button is pressed. Ties as lines — Displays ties as lines (figure 5-11).
N Master reset does not reset the Internet protocol (IP) settings. Using Emulation mode 1. Double-click the Matrix Switchers Control Program icon in the Extron Electronics group or folder. 2. Choose Emulate, and click OK. 3. Choose an emulation file to open, and click OK. The file DEMO.MTX provides a sample of a completed matrix setup. Selecting the file NEW.INI or clicking Cancel provides a blank setup to get you started. 4.
Matrix Software, cont’d By default, the Windows installation creates a C:\Program Files\Extron\ ButtonLabelGenerator directory and places the Button Label Generator icon into a group or folder named “Extron Electronics”. Using the Button-Label Generator software To run the Button-Label Generator program, click Start > Programs > Extron Electronics > Button Label Generator > Button Label Generator. The Button-Label Generator window appears (figure 5-14). PRELIMINARY 1.
