4.1 Single installation
Precaution:
1.
For users who would like to connect PC over PS/2 interface:
Please finish the connection to PC over PS/2 port before turning on PC.
PC will not detect PS/2 devices, if PS/2 is not connected while booting. It will
cause a mouse and keyboard error with no access to your computer.
When connecting a Windows 98 system , it is suggested that the PC must be
always plugged to PS/2 ports, because Windows 98 does not support
installation at first time through USB HID installation driver.
Some old PCs can support USB keyboard during booting, but are required to
open BIOS USB setting first.

4. For connecting Windows 2000, Window 2003, Window XP or later, in case of
PC is set as “need to be login with the password”and connects to KVM over
USB interface only, it is suggested that complete the installation of the KVM
switch before logging out the Windows system. In these case, the host is able
to recognize the USB HID device and install the driver and makes the KVM
switch works properly in the next booting.
5. The KVM switch is powered by either PS/2 keyboard port or USB port. For
Notebook or Laptop, power might not be strong enough to support KVM switch .
If KVM switch cannot work properly with your Notebook, it is suggested that
using a DC switching power adaptor with 5V/300mA~1A to the KVM power
jacket. For polarity, see following:
6. For USB Keyboard with built-in USB HUB, please note that the KVM
switch does not support the built-in USB HUB on USB keyboard.

and VGA video into the Console ports located on the KVM Switch’ front panel.
