Definitions - Extron electronics MVX VGA A User Manual

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.
Each matrix switcher can be remotely controlled via its rear panel RS-232/RS-422
Remote port and its front panel Configuration (RS-232) port using either Extron's
Windows
®
(SIS ). The SIS is 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 serial port.
Either serial 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 switchers are housed in rack-mountable, 2U (MVX 128 VGA A) or 3U
(all other models) high metal enclosures with mounting flanges for standard 19"
racks. The appropriate rack mounting kit is included with each switcher.
The switchers have an internal 100 VAC to 240 VAC, 50/60 Hz, 30 watts
autoswitchable power supply that provides worldwide power compatibility.
The MVX A switchers have a minimum bandwidth of 300 MHz (-3 dB). The
switchers 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 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.
