Switch modes

The SW6 VGA Audio switcher operates in manual or auto switch mode.

•Manual switch mode — Input selection is done using Input buttons 1 through 6 on the front panel or through the rear panel Remote connector (contact closure or RS-232).

•Auto switch mode — The switcher automatically selects the highest number input that has sync pulses available. Input selection by the front panel switches or through the Remote connector is blocked.

Determining the switch mode

To determine which mode is active, press and release an unselected input button.

Normal switch mode — That input becomes the selected input.

Auto switch mode — The switcher does not select the input associated with the button that you pushed.

Selecting a switch mode

Switch between modes by pressing and holding the Mode (Input 1 button) and either the Normal (Input 2) or Auto (Input 3) button until either the Normal or Auto LED blinks (figure 2-10).

Press and HOLD.

1 sec.

The blinking LED indicates the mode.

Release the buttons.
