EATURES
Chapter 5 provides an introduction to using the TCP/IP features
on your BL2000 board.
5.1 TCP/IP Connections
Before proceeding you will need to have the following items.
•
If you don’t have Ethernet access, you will need at least a 10Base-T Ethernet card
(available from your favorite computer supplier) installed in a PC.
•
Two RJ-45 straight through Ethernet cables and a hub, or an RJ-45 crossover Ethernet
cable.
The Ethernet cables and Ethernet hub are available from Rabbit in a TCP/IP tool kit. More
information is available at
www.rabbit.com .
1. Connect the AC adapter and the programming cable as shown in Chapter 2, “Getting
Started.”
2. Ethernet Connections
If you do not have access to an Ethernet network, use a crossover Ethernet cable to con-
nect the BL2000 to a PC that at least has a 10Base-T Ethernet card.
If you have Ethernet access, use a straight through Ethernet cable to establish an Ethernet
connection to the BL2000 from an Ethernet hub. These connections are shown in Figure 21.
