6.1 TCP/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.
Figure 14. How to Identify Straight-Through and Crossover Ethernet Cables
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.
