Front Panel Operations

Plug in all system components and turn on the input devices
(such as desktop computers and laptops) and the output
monitor. Select an input. The image should appear on the
monitor.

Normal and auto switch modes

All SW VGArs / Ars Series switchers can operate in either
normal (manual switch) mode or auto switch mode. In auto
switch mode, the highest numbered input with a sync signal
present is automatically selected for output. If no sync signal is
present, no input is selected. Input selection by the front panel
buttons is blocked while the switcher is in auto switch mode.
However, the front panel LEDs remain functional and the
buttons can be used to view or change the mode.

Viewing the current switch mode

You can determine the current switch mode at any time by
noting the state of the Auto Switch Active LED. This LED is lit
if the switcher is in auto switch mode.

Selecting normal switch mode

Press and hold the Input 1/Mode button while you press and
release the Input 2/Norm button. The Auto Switch Active LED
turns off, indicating normal switch mode. Release the
Input 1/Mode button.
