Chapter 6. Using The Tcp/Ip Features; Tcp/Ip Connections - Rabbit RCM3000 User Manual

6.1 TCP/IP Connections

Programming and development can be done with the RCM3000 RabbitCore modules without con-
necting 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
RCM3000 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
• Two RJ-45 straight through Ethernet cables and a hub, or an RJ-45 crossover Ethernet
The Ethernet cables and a 10Base-T Ethernet hub are available from Rabbit Semiconduc-
tor in a TCP/IP tool kit. More information is available at www.rabbit.com.

Setup."
There are four options for connecting the RCM3000 module to a network for develop-
ment and runtime purposes. The first two options permit total freedom of action in
selecting network addresses and use of the "network," as no action can interfere with
other users. We recommend one of these options for initial development.
No LAN — The simplest alternative for desktop development. Connect the
RCM3000's Ethernet port directly to the PC's network interface card using an RJ-45
crossover cable. A crossover cable is a special cable that flips some connections
between the two connectors and permits direct connection of two client systems. A
standard RJ-45 network cable will not work for this purpose.
Micro-LAN — Another simple alternative for desktop development. Use a small Eth-
ernet 10Base-T hub and connect both the PC's network interface card and the
RCM3000's Ethernet port to it, using standard network cables.
