3.1Connecting to the Network

Besides the WebNet Start Kit, you need a computer with TCP/IP and a web browser installed on it. The computer must be equipped with a network adapter. You can either connect the WebNet Start Kit directly to the network adapter on the computer, or you can connect it to a network hub or switch on the local area network.

3.1.1Connecting to a hub

When connecting to a hub to which the computer is attached, the “straight” network cable supplied with the Start Kit is used. Make sure that the hub is capable of running 10Mbps. Old hubs only run 10Mbps and many new dual-speed hubs automatically detects the speed and run either 10 or 100Mbps (or is able to switch packets between devices of different speeds), but some new hubs only run 100Mbps. The only solution in the latter case is to replace the hub.

Also make sure that the WebNet and the computer are on the same segment of the LAN, that is, no routers or bridges are in between the two devices. Hubs or switching hubs are OK.

3.1.2Connecting to a network switch

Connecting the WebNet to a network switch, before an IP-address is configured, is not recommended. Some network switches might filter out packets addressed to “unknown” MAC addresses. Once the WebNet is properly configured, there are no problems in con- necting it to a network switch. Use the same network cable as when connecting to a hub.

3.1.3Connecting directly to the computer

To connect the WebNet directly to the computer, a “crossed” network cable is required (the one supplied with the Start Kit is “straight” and can not be used for this purpose). The network adapter in the computer must be capable of running 10Mbps.

In case of problems, configure the network adapter to 10Mbit link speed or “auto-sense” – 100Mbit will not work. Notice that the link speed cannot be set on all types of network adapters.

For Windows computers the setting would appear (if applicable) in

Control Panel -> Network -> (Adapter name) -> Properties -> Advanced -> Link speed

The crossed network cable is connected to the network adapter in the computer and to the WebNet.
