Modes of Operation
Auto Mode – This will select the VGA input with the highest priority
that has an active VGA signal.
Scan Mode – Will select each active VGA signal for a specified
number of seconds, 1-60, and then switch to the next active VGA
input. The VS-4 can also be configured to scan the non-active VGA
inputs as well as the active VGA inputs.
Normal Mode – VGA inputs are selected based on user input.
The VS-4 can only be in one of these modes at a time.
Front-Panel Switches
The front panel switches may be locked out so pressing them has no

accomplished via the serial RS-232 commands.

no VGA signal to be displayed then you will see a black screen. The
VS-4 will enter Normal Mode any time a single front panel button is
pressed and the front panel is not locked.
The second use of the front panel buttons is to put the VS-4 into Auto
