Extron electronic MVX 84, MVX 88, MVX 44, 48 manual Operations, Definitions, Powering up the Switcher

Operations

The following paragraphs define matrix switcher terms and then detail the power-up process and then provide sample procedures for creating ties, sets of ties, and configurations; changing a configuration; viewing ties, sets of ties, and configurations; saving a preset; recalling a preset; viewing and adjusting the audio level; and selecting the front panel security lockout.

Definitions

The following Extron matrix switcher terms 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 — Consists of 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. Sixteen global memory presets can be stored in memory. The input and output buttons select preset memory locations to load or retrieve. When a preset is retrieved from memory, it becomes the current configuration. On each model, there are as many presets available from the front panel as there are input and output buttons:

•The MVX 44 has 8 presets available on the front panel.

•The MVX 48 and MVX 84 have 12 presets available on the front panel.

•The MVX 88 has 16 presets available on the front panel.

On smaller MVX models, presets that are not available from the front panel are still available under RS-232 or optional IR 501 control.

Powering up the Switcher

1.Plug in the switcher. On all switcher models, power is automatically applied when the power cord is connected to an AC source. When AC power is applied, the switcher performs a self-test and initialization that sequences the front panel LEDs on and off from left to right. A successful power up self-test and initialization leaves the power LED on, the Video and Audio LEDs on, and all other LEDs off.

The current configuration, all presets, and all input audio levels are saved in non-volatile memory within 5 seconds of a change or exiting Audio Setup mode. When power is applied, the most recent configuration is retrieved. The previous presets remain intact.

NOTE: Wait at least 5 seconds after changing any configuration, saving a preset, or exiting Audio Setup mode. Before 5 seconds have elapsed, changes that

you have made may not have been saved.

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 S3 Sales and Technical Support Hotline. See the last page of this guide for the phone number in your region of the world.

2.Plug in all system components and turn on the input devices (such as computers or

HDTV set-top boxes) and the output devices.

3.Set the input devices to output video using the operating instructions for each device.

4.Create a tie (see below). The selected input image should appear at the selected output. If no image appears, see “Troubleshooting” on page 31.
