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.

2. 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.

3. 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:
