Installation
Important
1. Before you begin, make sure that the power to all the devices you will be connecting has
been turned off. You must unplug the power cords of any computers that have the
Keyboard Power On function. Otherwise, the switch will receive power from the
computer.
2. To prevent damage to your equipment, make sure that all the devices you will be
connecting are properly grounded.
Installing your new KVM-0223 involves the following steps:
1. Plug your keyboard, monitor, and mouse into their ports on the KVM-0223. The keyboard
and mouse ports are labeled with an icon to distinguish them.
2. Plug your speakers into the KVM-0223’s speaker jack. *This step is optional
3. Plug the USB, video, and speaker connectors of the attached KVM cables into their
respective ports on the computers you are installing.
4. Turn on the power to the computers.
Note: The KVM-0223
Plug the keyboard in before plugging in the mouse. When using a
wireless composite keyboard and mouse, its USB cable must plug into
the KVM-0223’s keyboard port for the Hotkeys to function.
The mouse connector is actually a USB port, and can accept any USB
compatible peripheral. You can even connect a hub to install multiple
USB devices.
’s Power On default is to link to the first computer you turn on.
