2.4.2 Connecting Directly to a Host System
This option is used under the following situation:
• Evaluation of the Development Board as part of a test system;
• Operation on an isolated network is desired or;
• Connection to a deployed network is not possible.
To set up the board for connection to a local host (see Figure 2-2):
1. Unbox and unwrap the board, and set it on a non-conductive surface near the
host computer.
2. Depending on the network connection to be used, do one of the following:
For connections through an Ethernet hub or switch: Connect a standard
Ethernet cable to the board, then to a port on the Ethernet device (Option “A” in
Figure 2-2). The computer should already be connected to the hub or switch by
a straight-through cable.
For direct connections to a host system: Connect the Ethernet crossover
cable (supplied in the kit) to the board, then to the computer (Option “B” in
Figure 2-2).
3. Apply power to the board (9 V
DC) at J7. (See Section 2.4.1 “Connecting to a
Network” for power supply requirements.)
