devices you will be connecting up have been turned off.
1. Plug the keyboard and mouse into the appropriate
ports on the front of the KVM switch. Connect the
monitor to the Console port located on the back of
the switch.
2. Use the cables in the cable kit (see Hardware
Requirements section) to connect the monitor, key
board and mouse ports of each of the PCs to the
appropriate ports on the back of the switch.
3. Turn on the power to the connected PCs.
Note: The switch’s Power On default links the switch
to the first computer you turn on.

Turn off the PCs. Wait 5
seconds; then turn the

Wrong type of
mouse or adapter
The switch will only
work with a PS/2
mouse. A serial mouse
cannot be converted to
a PS/2 mouse by using
a serial to PS/2 adapter.
One exception is a
combo-mouse which is
specifically designed for
both applications. In
this case, ensure that
the mouse is set up for
PS/2 mode and is being
used with the adapter
originally provided.
Unsupported or
incorrect mouse
driver
Each PC needs to be
using the mouse driver
correlating to the mouse
connected to the
console port.
Some newer mice (with
extra buttons and
wheels) have unique
drivers that may not be
supported. Try a regular
mouse with a generic
mouse driver (like the
one that comes with the
operating system).
Problem Cause Solution
* This Switch is designed to work with AT and PS/2
keyboards. Older XT (84 key) and some older AT
keyboards (those with the function keys on the side)
will not work.
** Some Notebook computers, notably the IBM
Thinkpad and Toshiba Tecra, have trouble
working with a switch when their mouse and
keyboard ports are used simultaneously. To avoid
this problem, only connect the mouse port or the
keyboard port to the Switch. If you connect the
mouse port, you will need to use the notebook’s
keyboard when the notebook is the active
computer.
