5.2.2 How to Set Up your Computer’s IP Address for a Direct Connection

When your computer is connected directly to the OP6800 via an Ethernet connection, you need to assign an IP address to your computer. To assign the PC the address 10.1.1.1 with the subnetmask 255.255.255.248 under Windows 98, do the following.

Click on

Start > Settings > Control Panel

to bring up the Control Panel, and then double-click the Network icon. Depending on which version of Windows you are using, look for the

TCP/IP Protocol/Network > Dial-Up Connections/Network

line or tab.

Double-click on this line or select

Properties

or

Local Area Connections > Properties

to bring up the TCP/IP properties dialog box. You can edit the IP address and the subnet mask directly. (Disable “obtain an IP address automatically”.) You may want to write down the existing values in case you have to restore them later. It is not necessary to edit the gateway address since the gateway is not used with direct connect.
