Installation

Hardware Installation

1. Using standard USB A-to-B cables, connect each computer to the

numbered ports on the switch.

2. Connect the USB peripheral to share into the side USB port on the

switch.

Driver Installation

The USB Sharing Switch does not require special drivers to work. Drivers

for the USB peripheral device still need to be installed, if necessary.

Software Installation (Windows only)

The Switching AP software allows for switching the USB peripheral

between ports/computers without physical access to the switch.

1. Upon starting Windows, insert the included Software Installation CD into

the computer’s CD/DVD drive.

2. AutoPlay should automatically launch the Software installation screen. If

not, open “My Computer” and right-click on the CD/DVD drive the disk is

inserted into and select “AutoPlay” or run the setup.exe ﬁle on the CD.

3. Proceed through the installation wizard until completed. Once

completed, there should be a small icon in the System Tray (next to

Clock) for the switching application.

How to Use

Switching

There are three methods to switching the USB peripheral between the

connected computer systems:

• Push Button: pushing the top buttons on the switch itself, directly

connects the USB peripheral to the selected port/computer.

• Hotkeys: pressing <CTRL> + <F11> switches the USB peripheral to the

current computer. Requires the Switching Software to be installed.

• Software: right-clicking the tray icon for the software and selecting

“Switch” will connect the USB peripheral to the current computer.

The Icon will either be green or yellow in color, to indicate the current

state of the switch. When green, the USB peripheral is connected

to the current computer system. When yellow, the USB peripheral is

connected to a different Port/computer.
