Hardware Installation
1. Connect the VGA monitor/display to the VGA output connector on the Video Switch. Power
on the monitor/display.
2. Connect a male/male VGA cable from the VGA video source (i.e. computer video card) to the
Port 1 VGA input on the Video Switch. This is the Primary input, so will be automatically
selected, when a video signal is present.
3. Using a male/male VGA cable, connect the secondary VGA video source to the Port 2 VGA
input on the Video Switch. This is the Secondary input, so will be automatically selected, if
a video signal is not present on the Primary input.
4. Connect the external power adapter to the Video Switch.
5. Power on the VGA video sources one at a time. The Online LED on the front panel will light
up when a video signal is found for each input.
Driver Installation
No driver or software installation is required on any computer system.
How to Use
The Primary input on the Video Switch take precedence when a video signal is present. When a
video signal is no longer present on the Primary input, the Video Switch will automatically switch
to the Secondary input. Once a video signal is restored to the Primary input, the Video Switch
will automatically switch to the Primary input.
The selected input on the Video Switch can be manually chosen via the front panel buttons.
Pressing the “Select” button for the desired input will immediately select it. This selection will
remain in affect, until a video signal disconnect/reconnect is sensed on the Primary input.
