Extron electronic MPX Plus 866 A manual Creating a configuration

PRELIMINARY

Operation, cont’d

Power

Apply power by connecting a power cord between an AC source and the rear panel power connector. The switcher performs a self-test that flashes the front panel button indicators green, red, and amber and then turns them off. An error-free power up self-test sequence leaves all input, output, and control buttons either unlit or showing background illumination and the Video button and the Audio button lit.

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. See the rear cover of this manual for the phone number in your region of the world.

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 Video button and/or
	Audio button.
3.	Select the desired input and output(s) by pressing the input and output buttons.
	The input button lights. The output buttons light or blink as follows:
	• Amber to indicate video and audio ties
	• Green to indicate video only ties
	• Red to indicate audio only ties.
	To indicate tentative 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 tentative 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.
