1.Connect the AC adapter and the serial programming cable as shown in Chapter 2, “Get- ting Started.”

2.Ethernet Connections

There are four options for connecting the RCM4000 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 RCM4000 module’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 RCM4000 module’s Ethernet port to it using standard network cables.

The following options require more care in address selection and testing actions, as conflicts with other users, servers and systems can occur:

•LAN — Connect the RCM4000 module’s Ethernet port to an existing LAN, preferably one to which the development PC is already connected. You will need to obtain IP addressing information from your network administrator.

•WAN — The RCM4000 is capable of direct connection to the Internet and other Wide Area Networks, but exceptional care should be used with IP address settings and all network-related programming and development. We recommend that development and debugging be done on a local network before connecting a RabbitCore system to the Internet.

TIP: Checking and debugging the initial setup on a micro-LAN is recommended before connecting the system to a LAN or WAN.

The PC running Dynamic C does not need to be the PC with the Ethernet card.

3.Apply Power

Plug in the AC adapter. The RCM4000 module and Prototyping Board are now ready to be used.
