When using the configuration with a serial terminal, reset PS/2 KVM over IP switch and immediately press ESC. You will see some device information and a ’=>’ prompt. Enter ’config’, press < Enter > and wait a few seconds for the configuration questions to appear.

As you go along you will see the following lines, which you have to answer or to which you may provide the default value by pressing < Enter >. The default value is shown in square brackets.

IP auto configuration (none/dhcp/bootp) [dhcp]:

IP [192.168.1.22]:

NetMask [255.255.255.0]:

Gateway (0.0.0.0 for none) [0.0.0.0]:

. IP autoconfiguration

With this option you can specify whether PS/2 KVM over IP switch should fetch its network settings from a DHCP or BOOTP server. For DHCP you have to enter DHCP and for BOOTP supply bootp accordingly. If you specify none then IP autoconfiguration is disabled and you will subsequently be asked for the following network settings.

. IP address

The IP address the PS/2 KVM over IP switch should use. This option is only available if IP autoconfiguration is disabled.

. Subnet mask

The mask of the connected IP subnet. This option is only available if IP autoconfiguration is disabled.

. Gateway address

The IP address of the default router of the connected IP subnet. If you have no default router, you may enter 0.0.0.0. This option is only available if IP autoconfiguration is disabled.

There may be default values which are enclosed in brackets. If you want to use the default value of an option then you just need to press the Enter key.

You will be asked if the values are correct and get a chance to correct them. After confirming, PS/2 KVM over IP switch performs a reset.

4.1.3 Mouse, Keyboard and Video configuration

There are two interfaces between PS/2 KVM over IP switch and the host for transmitting keyboard and mouse data: USB and PS/2. The correct operation of the remote mouse depends on several settings which will be discussed in the following:

4.1.3.1 Host system mouse settings

The host’s operating system also knows various settings for the mouse driver. While PS/2 KVM
