2.4 Ethernet Communication
This section describes the additional hardware connections needed to use the RabbitFLEX BL300F Ether-
net port. An Ethernet port is available on the PowerCore 3800, but not on the PowerCore 3810. You must
have a core module with an Ethernet port and your host computer will need one as well. You may create a
direct or an indirect network connection from the target board to the host computer. The core module uses
traditional 10Base-T Ethernet, with an RJ-45 jack which is shown in
Figure
2.4.

To communicate on a network, the RabbitFLEX board must be connected to the network with the appro-
priate cable and the board must be assigned an appropriate IP address. Other addresses may be necessary,
depending on whether the network is isolated or is addressable on the Internet. For development, it is bet-
ter (read easier) to use an isolated network as opposed to one connected to the Internet. Either is possible,
and both will be discussed here.
Before proceeding you will need to have two straight through Ethernet cables and a hub, or a crossover
Ethernet cable. The Ethernet cables and a 10Base-T Ethernet hub are available from Rabbit in the TCP/IP
10Base-T Accessory Kit. More information is available at:
