. Manually Switched Output
The SEL1 through SEL 4 buttons are used to select between video &
audio input sources of Video 1 through Video 4. A solid-on LED is used
to indicate which input is selected.
Holding down any of the SEL buttons for 3 seconds will blank that
selected input source (and mute the audio output). The LED for that
selected input will start blinking to indicate the blanking mode. Pressing
that SEL button again will un-blank the output and un-mute the audio on
the Video Output rear connector.

. Modes of Operation
The unit can operate in either Auto or Manual mode. Pressing the SEL 1
and SEL 2 buttons simultaneously for 3 seconds will select AUTO mode.
Pressing any SEL button selects MANUAL mode.
When in Auto mode, the SEL 1 and SEL 2 LEDs will flash to indicate the
mode is active.
In Auto mode, the DVS-4A will automatically select the input with active
video and audio. The presence of video is determined by examining the
V. Sync signal or optionally the +5 VDC signal from DVI input
connectors. The front panel SEL buttons cannot be used to switch
between ‘Video 1’ through ‘Video 4’ sources in this mode. Pressing any
of the SEL buttons will take the unit out of AUTO mode.
In Manual mode, the output of the DVS-4A will depend on the selection
of the SEL buttons.
