The PC is Connected In
Network
If there is an Ethernet network available (see Figure 5), the Embedded Internet Toolkit
can be connected to any Ethernet connection or hub belonging to the network. If the PC
is connected to a network, there is a strong possibility that the default IP address of the
Toolkit is outside the range of the network (the address doesn’t belong to the IP subset
of the network). If the Ethernet network is connected to the Internet, this is certain. In
this case, a new IP address for the Toolkit is required. Contact the local network admin-
istrator to be assigned a free IP address for the Toolkit, then See “Using the Web Server
Terminal Software” on page 7. for a description on how to configure the Toolkit’s IP
address.
In the remainder of this document, the IP address 169.254.111.111 is used as an exam-
ple. Exchange this IP address with the IP address you have set up in all the
occurrences.

Testing the Connection
To test the connection between the PC and the Internet Toolkit a simple program called
ping
can be used.
Ping
sends a number of messages to the specified IP address and
displays the response. The ping program can be run from the command line or from a
DOS window on the PC, as follows:
•
Open the Windows
®
Start Menu.
•
Click Run.
•
In the Open box, type: “ping 169.254.111.111”.
If the network connection is OK, the program will respond with:
"Reply from 169.254.111.111" and information about the response time.
If there is a problem with the network setup the program will respond:
"Destination host unreachable"
. There may be two solutions for this problem:
•
If the PC is connected to a network, change the IP address to an address
accessible from the local network, as described in “The PC is Connected In
Network” on page 5.
•
If the Toolkit is connected directly to the PC (or through a hub), change the PC’s IP
address to one in the same address range as the Toolkit, as described in “The PC is
Not Connected to Network” on page 2.
If there is a problem with the Embedded Internet Toolkit the program will respond:
