Extron electronic 450 Plus Series manual Power, Creating a configuration

Operation, cont’d

Power

Apply power by connecting the power cord to an AC source. The switcher performs a self-test that flashes the front panel button indicators green, red, and amber and then turns them off. (The order in which the colors are displayed depends on the model.) An error-free power up self-test sequence leaves all I/O and control buttons either unlit or showing background illumination. The lit/unlit status of the RGBHV or Video button and the Audio button is defined by the system configuration as follows:

•Systems with audio — RGBHV/Video and Audio both lit

•Systems without audio — RGBHV/Video lit and Audio 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 S3 Sales & Technical Support Hotline.

Creating a configuration

The current configuration can be changed using the front panel buttons. Change the current configuration as follows:

1.	Press the Esc button to clear any input button indicators, output button
	indicators, or control button indicators that may be lit.
2.	Select to configure video, audio, or both by pressing the RGBHV
	(CrossPoint 450 Plus switchers) or Video (MAV Plus switchers) button and/or
	Audio button.
3.	Select the desired input and output(s) by pressing the input and output
	buttons.
	Input buttons light amber (matrix sizes up to 1616) or green (matrix sizes
	above 1616). Output buttons light or blink amber to indicate video and audio
	ties, green to indicate video only ties, and red to indicate audio only ties.
	To indicate potential ties, output buttons blink the appropriate color when an
	input is selected.
	To indicate current ties, output buttons light steadily the appropriate color
	when an input is selected.
	To clear unwanted outputs, press and release the associated lit output
	buttons. To indicate potential unties, output buttons blink the appropriate
	color when an output is deselected but not untied from the input.
4.	Press and release the Enter button to accept the tie.
5.	Repeat steps 1 through 4 to create additional ties until the desired
	configuration is complete.

• Only one video input and one audio input can be tied to an output.

•If a tie is made between an input and an output, and the selected output was previously tied to another input, the older tie is broken in favor of the newer tie.

•If an input with no tie is selected, only that input’s button lights.
