RabbitLink (EG2110)
2.4 Ethernet Connections
Before proceeding, you will need to have either two straight-through Ethernet cables and an Ether-
net hub or one Ethernet crossover cable. The Ethernet cables and Ethernet hub are available from
Rabbit Semiconductor or Z-World in a TCP/IP tool kit. More information is available at
www.rabbitsemiconductor.com
or at
www.zworld.com
Your PC must have an RJ-45 Ethernet jack. You can identify the RJ-45 Ethernet jack by looking
for an 8-connector (as opposed to a 6-connector RJ-11 phone jack) jack labeled
ETHERNET
or
<···>
that will probably have an LED or two on it. If your PC does not have Ethernet access, you
will need to install a 10BaseT Ethernet card.
Connect your PC and the RabbitLink board to an Ethernet hub as shown in Figure 2.4.0-1. The
Ethernet hub may also be connected to your network.
Figure 2.4.0-1 Overview of physical connections.
Alternatively, you may use the crossover Ethernet cable to connect the RabbitLink directly to a PC
RJ-45 Ethernet jack. This is useful when using RabbitLink as a high speed local programming
interface.
2.5 Ready to Go
The green LED labeled
LINK
should light up once all the connections have been made correctly.
Dynamic C or the Rabbit Field Utility may now be used to download a program to the Rabbit-
based target system from your PC. The red LED labeled
USER
on the RabbitLink blinks while a
download or a debug session is in progress.
