†Are the WebNet and the PC on the same network segment?

†Is the connected hub/switch or network adapter capable of running 10Mbit?

†Did you type the correct MAC/IP addresses in the arp-command? Check it with arp -a (lists all arp entries)

†Is the unit properly connected (check the link indicator LED on the hub/switch or network adapter that the board is connected to)?

†Did you wait approx 10 seconds after power-on before issuing the ping?

The auto-IP is typically the way to assign an IP address the first time. Setting the IP address permanently is explained in section 4.2. The IP configuration is detailed in appendix B.

3.4Browsing the WebNet

The web server contained in the WebNet module is always active. Thus, you can browse its contents as soon as you have assigned the module its IP address.

Simply type the IP address of the WebNet in the “location” field (where you normally type URL’s manually) of your browser, and press ‘enter’.

If you are on a network with a proxy web-server (a typical company LAN) you may ex- perience that the browser “hangs” when trying to connect to the WebNet. You probably have to adjust your “proxy exceptions”, so as not to redirect your WebNet-traffic to the proxy-server. In Internet Explorer, proxy exception settings are found in:

Options -> Internet settings -> Connections -> LAN Settings -> Proxy Server/Advanced -> Exceptions

In Netscape, they are found at

Edit -> Preferences -> Advanced -> Proxies -> View -> Exceptions

In the list of exceptions, add the IP address of the WebNet module. When all is set up right, the home page of the WebNet appears:

Now would be a good time to read the first 5 bullets on the page, which contain lots of useful information about the WebNet: Its background, its HW and SW architecture, and descriptions of lots of features, among many other things.
