Extron electronic MVX PLUS 128 manual Definitions, MVX Plus 128 VGA Matrix Switchers Introduction

The MVX Plus 128 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 Ethernet port and its RS-232/RS-422 port. The matrix switcher is programmed with Extron’s Simple Instruction Set™ (SIS™), 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 the Ethernet link or the RS-232/RS-422 link.

The Ethernet port can be connected through a local area network (LAN) or wide area network (WAN).

The MVX Plus 128 features e-mail notification of maintenance or other concerned personnel concerning the status of the power supplies and the loss or resumption of sync on individual inputs.

The RS-232/RS-422 port can be connected to a control system, a PC, or Extron’s MCP 1000 remote control panel and/or MKP 1000 remote keypad.

The matrix switchers are housed in rack-mountable, 2U high metal enclosures with mounting flanges 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 Plus 128 has a minimum bandwidth of 300 MHz (-3 dB). Both models can also switch RGBS, RGsB, RsGsBs, HDTV, component video, S-video, and composite video.

Definitions

The following terms, which apply to 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 (where necessary) output buttons. Up to 20 presets can be selected from the front panel for either saving or retrieving. When a preset is retrieved from memory, it becomes the current configuration. All models have 32 presets; preset numbers larger than 20 are still accessible under RS- 232/RS-422 or Ethernet control.
