Introduction • About this Guide • About the Switchers • Features About this Guide This guide contains installation, configuration, and operating information for the Extron® MVX VGA Matrix Switchers. About the Switchers The Extron MVX Series VGA matrix switchers (see figure 1) is a family of computer video matrix switchers that distribute any VGA or component/HDTV video (or other high resolution video) and audio input to any combination of outputs.
NOTE: The switchers can also distribute S-video and composite video with applicable adapters. The MVX switcher can be locally controlled from the front panel or remotely controlled via its rear panel RS-232 serial port or an optional IR 501 Small Matrix Infrared (IR) Remote Control (part number 70-336-01). Features Video — These switchers input and output VGA – UXGA RGBHV, RGBS, RGsB, RsGsBs video, or component/HDTV signals on 15-pin HD female connectors. Bandwidth — Bandwidth is 300 MHz (–3 dB).
Upgradeable firmware — The firmware that controls the operation of the switcher 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 website, www.extron.com, and they can be installed using the Windows-based control program. Global memory presets — Sixteen global memory presets are a time-saving feature that lets you set up and store input/output configurations in advance.
Installation This sections details the installation of the MVX VGA Matrix Switchers, including: • Mounting the Switcher • Cabling and Rear Panel Views Mounting the Switcher CAUTION: Installation and service must be performed by authorized personnel only. Detailed mounting instructions can be found in the “Reference Information“ section at the end of this guide. The 1U high matrix switchers can be placed on a tabletop or mounted on a rack shelf. Use the included hardware for rack mounting.
Video and Audio Input Connections a RGB video inputs — Connect the analog computer-video sources to these 15-pin HD female connectors. NOTE: 1 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 screen shuts off once that port is activated.
NOTES: • The length of exposed wires is critical. The ideal length is 3/16 inch (5 mm). • If the stripped section of wire is longer than 3/16 inch, the exposed wires may touch, causing a short circuit. • If the stripped section of wire is shorter than 3/16 inch, wires can be easily pulled out even if tightly fastened by the captive screws. • Figure 4 on the preceding page identifies the tip, ring, and sleeve. A mono audio connector consists of the tip and sleeve.
Power Connection e AC power connector — Plug a standard IEC power cord into this connector to connect the switcher to a 100 VAC to 240 VAC, 50 or 60 Hz power source.
Operation This section describes the front panel operation of the MVX VGA Matrix Switcher, including: • Front Panel Controls and Indicators • Operations • Optimizing the Audio • Troubleshooting • Worksheets Front Panel Controls and Indicators The number of input and output buttons and LEDs that each MVX Series VGA matrix switcher provides varies with the number of inputs and outputs. Figure 6 shows the front panel of an 8-input, 8-output video and audio switcher.
Infrared Sensor and Power/audio/data LED a 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 Guide. NOTE: b Keep the switcher out of bright light to prevent interference with the IR signals from the IR 501 remote control.
Control Buttons and LEDs e f Enter button — The Enter button saves changes when you set up a new configuration. To create a simple configuration: • Specify video, audio, or both (see controls [item g] and [item h]). • Press the desired input button (item c). • Press one or more desired output buttons (item d). • Press the Enter button. Preset button and LED — The Preset button activates either Save Preset mode or Recall Preset mode. Save Preset mode saves a configuration as a preset.
i Audio Setup LED — The Audio Setup LED lights red to indicate that the switcher is in Audio Setup mode. See “Adjusting Input Audio Gain and Attenuation” on page 23. Alternate IR error function — The Audio Setup LED also indicates errors when you use an IR 501 small matrix remote control. The LED lights for approximately 1 second when the switcher receives an unexpected or out-of-sequence IR command from the remote control. The switcher otherwise ignores the command.

Example 7: Recall a preset The following steps show an example in which a preset is recalled to become the current configuration. The example shows the front panel indications that result from your actions. 1. Select Recall Preset mode: Press and release the Preset button. Press and release the button. PRESET The LED lights to indicate Recall Preset mode. All input and output buttons with assigned presets light. If you then recall the configuration from an unlit preset number, all ties will be cleared.
Adjusting Input Audio Gain and Attenuation Switchers have input audio gain and attenuation adjustments. In Audio Setup mode, the audio level 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 (see figure 12).
By noting the status of these LEDs and counting the number of 1 dB steps 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.
2. Select an input: Press and release the Input 5 button. 10 6 3 0 3 + VU Press and release the Input 5 button. INPUTS 4 OUTPUTS 5 1 6 2 3 4 +dB A VU meter connected to output 1 indicates that the adjusted level is approximately +9 dB above the –10 dBV internal level. -dB The Input 5 LED lights to indicate that input 5 is selected. The Output 1, Output 2, and Output 3 LEDs display the audio level range of input 5. The +dB LED indicates a gain (positive) level.
3. Decrease the audio level: Press and release the < button once. The < LED flashes each time the button is pressed Press and release the < button several more times to continue to decrease the audio level (see figure 13). Note the output LED, +dB LED, and –dB LED changes that occur each time the < button is pressed and released. Figure 13 shows the result of pressing the < button a total of 9 times to change the value to -1 dB.
Example 9: Resetting audio gain — single input Reset the audio gain or attenuation for a specified input to the factory default (0 dB) as follows: 1. Select Audio Setup mode: Press and hold the Audio Setup (I/O) button for approximately 2 seconds. Press and hold the button. 2 seconds AUDIO SETUP AUDIO SETUP The LED lights to indicate Audio Setup mode. Release the Audio Setup button. 2. Select an input: Press and release the Input 5 button. Press and release the Input 5 button.
Example 10: Resetting audio gain — all inputs To reset the input audio gain or attenuation to the factory default (0 dB) for all inputs, press and hold the Audio Setup (I/O) button for approximately 10 seconds (see figure 14). Press and hold the button. 10 seconds total Continue to hold the button. AUDIO SETUP 2 seconds AUDIO SETUP The LED goes off and then flashes twice to indicate the audio reset of all inputs. Release the Audio Setup button. Figure 14.
Clearing all Ties and Presets To clear all ties and saved presets, press and hold the Preset button on the front panel while applying AC power (see figure 16). Continue to hold the Preset button until all LEDs light and then release the Preset button. The power up sequence completes: • All LEDs turn off then turn on and off from left to right. • The Video and Audio LEDs turn on. • All other LEDs remain off. Press and hold the Preset button while you apply power to the switcher.
Resetting the System to Factory Defaults To reset a switcher to the factory default settings, press and hold the I/O button on the front panel while applying AC power (see figure 17). Continue to hold the I/O button until all LEDs light and then release the I/O button. The power up sequence completes (all LEDs turn off then turn on and off from left to right, the Video and Audio LEDs turn on, and all other LEDs remain off). System reset does the following: • Clears all ties and presets.
Optimizing the Audio 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 “Video and Audio Input Connections” and “Video and Audio Output Connections” in the “Installation” section.
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 35 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 18 shows a worksheet for an MVX 88 in a fictional organization with the system hardware annotated.
Worksheet Example 2: Daily Configuration Figure 19 continues from worksheet example 1 by showing the video and audio ties that make up the configuration of preset 1. A black line shows video ties and a red line shows the audio ties.
Worksheet Example 3: Test Configuration The A/V system in our fictional organization needs to be fine tuned on a regular basis. Figure 20 shows a typical test configuration, with an Extron video test generator (input 8) generating a test pattern to all monitors (outputs 1, 2, 3, 4, and 8). Sound checks are run from the CD player (input 5) to all audio systems (outputs 1, 2, 4, 5, and 8).

Remote Operation This section describes the operation of the MVX VGA Matrix Switcher, including: • IR Remote Control • Simple Instruction Set Control • Matrix Switchers Control Program SIS commands and the Matrix Switchers Control Program require a connection to the rear panel RS-232 port by either a host device, such as a computer, or a control system (see item d and “Remote Connection” on page 6).
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.
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.
