  • Page 11 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 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 • MVX 168 VGA A • MVX 1212 VGA A • MVX 1616 VGA A Extron VSC 500 Video Scan Converter Audio In Laptop Extron...

  • Page 12: Definitions

    Definitions The following terms, which apply to all 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 — 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 32 global memory presets can be stored in memory. Preset locations are assigned to the input buttons and output buttons. When a preset is retrieved from memory, it becomes the current configuration. The switchers have 32 presets. On the MVX 128 VGA A, up to 20 presets can be selected from the front panel for either saving or retrieving. Preset numbers larger than 20 are accessible via serial port control.

    • 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. MVX VGA A Matrix Switchers • Introduction...
  • Page 14 Global memory presets — 32 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 the front panel. For the MVX 128 A, which has fewer input and output buttons, 20 global memory presets are available from the front panel; the remaining presets are available via serial port control. Rack mounting — Rack mountable in any conventional 19" wide rack. Three front panel security lockout modes (Executive modes) — If a matrix switcher is installed in an open area, where operation by unauthorized personnel may be a problem, either of two security lockout modes can be implemented (the third mode is unlocked). When a front panel locked mode is enabled, a special button combination or SIS command is required to unlock the front panel controller and make the front panel fully operational. Power — The matrix switcher’s 100 VAC to 240 VAC, autoswitchable, internal power supply provides worldwide power compatibility.

    • 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. N The switcher is shipped from the factory in Lock mode 2. 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. Power 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 S Hotline. Sales & Technical Support MVX VGA A Matrix Switchers • Operation...

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.

    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. 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. As necessary, adjust the input audio level of each input (see “Viewing and adjusting the input audio level”, on page 3-25) so that the approximate output level is the same for all selected inputs. As necessary, adjust the output audio level of each input (see “Viewing and adjusting the output volume”, on page 3-30). RESET RESET Release the Reset button.

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.
