July 2005

Your host computer and the development board are the only two devices

connected to this simple point-to-point network. For most host operating

systems, it is necessary to assign your host computer an IP address on the

same subnet as the board. For example, the address 10.0.0.1 will work

fine. Any address in the 10.0.0.x subnet will work, and there is no

possibility of conflicting with another device on the network. After

modifying the host computer's IP address, your computer is ready to

connect to the web server. See “Browsing to Your Board” on page C–5 to

continue.

If you don't have the ability to change the IP address of your host

computer, you could change the IP address of the board to match the

subnet of the host computer. For example, if your computer's IP address

is 1.2.3.4, then you could assign the address 1.2.3.5 to your board. To

change the board IP address, follow the steps in “Static IP Address” on

page C–3.

Every time you reset the board, the web server will attempt to obtain an

IP address via DHCP, which takes two minutes to time out. You can abort

the DHCP process, or disable DHCP entirely by using the steps in “Static

IP Address” on page C–3.

Browsing to Your

Board

Once your board has a valid IP address (obtained from either DHCP self-

configuration or from flash memory), you can access the board via a web

browser (e.g., Microsoft Internet Explorer). To browse this site, open a

web browser and type the IP address of the board (four numbers

separated by decimal-points) as a URL directly into the browser’s

Address input field. You can determine your board’s IP address by

reading the messages displayed on the LCD screen
