10 RabbitLink (EG2100)
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 usually has an LED or two on it. If your PC does not have Ethernet access, you will need
to install a 10BaseT Ethernet card (available from your favorite computer supplier).
Connect your PC and the RabbitLink board to an Ethernet hub as shown in Figure 7. The Ethernet
hub may also be connected to your network.
Figure 7. 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 (version 7.03 or later) or the Rabbit Field Utility (version 2.0 or later) on your PC may
now be used to download a program to the Rabbit-based target system. The red LED labeled
USER
on the RabbitLink blinks while the download or a debug session is in progress.
