6. USING THE TCP/IP FEATURES
6.1 TCP/IP Connections
Programming and development can be done with the RCM4300 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 RCM4300 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 15 shows how to identify the two Ethernet cables based on the wires in the trans-
parent RJ-45 connectors.
Figure 15. How to Identify Straight-Through and Crossover Ethernet Cables
