MAC

The MAC address you want to assign to the ethernet chip.

The MAC address is a unique number that identifies your chip. You must use a different address for every W3100A chip in your network.

Example : 123.00.12.34.56.78

You need to specify 6 bytes that must be separated by dots. The bytes must be specified in decimal notation.

IP

The IP address you want to assign to the ethernet chip.

The IP address must be unique for every ethernet chip in your network. When you have a LAN, 192.168.0.10 can be used. 192.168.0.x is used for LAN’s since the address is not an assigned internet address.

SUBMASK

The sub mask you want to assign to the W3100A.

The sub mask is in most cases 255.255.255.0

GATEWAY

This is the gateway address of the ethernet chip.

The gateway address you can determine with the IPCONFIG command at the command prompt :

C:\>ipconfig

Windows 2000 IP Configuration

Ethernet adapter Local Area Connection 2:

Connection-specific DNS Suffix . :

IP Address. . . . . . . . . . . . : 192.168.0.3

Subnet Mask . . . . . . . . . . . : 255.255.255.0

Default Gateway . . . . . . . . . : 192.168.0.1

Use 192.168.0.1 in this case.
