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.
