6.USING THE TCP/IP FEATURES

6.1TCP/IP Connections

Programming and development can be done with the RCM4000 without connecting the Ethernet port to a network. However, if you will be running the sample programs that use the Ethernet capability or will be doing Ethernet-enabled development, you should connect the RCM4000 module’s Ethernet port at this time.

Before proceeding you will need to have the following items.

If you don’t have Ethernet access, you will need at least a 10Base-T Ethernet card (available from your favorite computer supplier) installed in a PC.

Two RJ-45 straight-through Ethernet cables and a hub, or an RJ-45 crossover Ethernet cable.

Figure 14 shows how to identify the two Ethernet cables based on the wires in the trans- parent RJ-45 connectors.

Ethernet cables and a 10Base-T Ethernet hub are available from Rabbit Semiconductor in a TCP/IP tool kit. More information is available at www.rabbit.com.

Now you should be able to make your connections.
