Extron electronic MVX 128 manual Definitions

Page 9

The MVX 128 A 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 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 the RS-232/RS-422 link.

The RS-232/RS-422 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

•An Extron MCP 1000 remote control panel and/or MKP 1000 remote keypad

The matrix switcher is housed in a rack-mountable, 2U high metal enclosure 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 128 A has a minimum bandwidth of 300 MHz (-3 dB). The switcher can also switch RGBS, RGsB, RsGsBs, HDTV, component video, S-video, and composite video.

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 (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. The switcher has 32 presets; preset numbers larger than 20 are still accessible under RS-232/RS-422 control.
