Configuring the LAN Interface of the Operating PC

There are two ways of configuring the Serial Modem on a PC using the configuration

tool via its Ethernet interface:

Direct PC <–> modem LAN connection with "cross-over patch cable"

The modem is connected directly to the operating PC using a cross-over patch cable.

The LAN interface of the computer must be assigned a fixed IP address for this

purpose.

Note: If the computer is operated in a company LAN, a variable IP address is usually

assigned by the server (see next section). If the Serial Modem is to be configured

directly via the cross-over cable with this computer, a fixed IP address must be

assigned to this computer for this time.

Select the appropriate "Local area connection" under "Network connections".
