Introduction

The ST122VGAU VGA Auto Switcher lets you share a single display between two computers

and prioritize your VGA signals. The switch features a primary and secondary VGA input, and

automatically outputs the signal from the primary input. When the signal feed connected to the

primary input is cut or turned o, the switcher automatically defaults to the video signal on the

secondary VGA input.

Installation

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 aect, until a video signal disconnect/reconnect is sensed on the Primary input.
