I'm testing the EB023 block with the testporgram and setup from the small CD (EB023_test.hex). When I switch on the programmer the program says "Starting up... completed" as it should (this only takes a fraction of a second). The "cable not connected" icon disappears from the tray so it would seem that the PC has seen the EB023 board. Yet I cannot ping the EB023 board using 192.168.0.2, it says "Time out at command" (in Dutch).

I have two internet connections, one uses an Eminent USB modem (this is the one I normally use). The EB023 is connected to a normal netwerk card. I have used the ip settings of this second card during the set-up procedure. I don't use a proxy server. It would seem everything is installed and functioning correctly, apart of course from the fact that it doesn't reply to ping (and thus also doesn't reply to a browser command).

The only odd thing I can see is that when I ping a connection to the internet is made, it seems as if the PC is looking for this ip address on the internet instead of on the network card. When I disconnect internet I get a different error message on the ping (The targethost is not available).

I use WinXP SP2 Dutch version on a high speed cable internet connection. Do you have any idea what I'm doing wrong?

Hello Bert,

Have you had a look at the information in this manual:
http://www.matrixmultimedia.com/Learnin ... ersion.pdf

That may help.

Unfortunately, problems like this are very much PC & network dependant and it is often very difficult to find out what is going on.

Protocol analysis tools, such as "Ethereal", may also help as these can show the exact nature of the traffic on your Ethernet.

After hours of messing about with settings and Ethereal, which is now called Wireshark btw, I finally found the problem.

In the pdf that came with the E-block it says that the ipadres of the networkcard needs to set. The instructions say that you can use ipconfig the find out the current ip address and enter that in the Network Connections Dialog on the PC. And it even gives an example.

This is not correct. You need to use ipconfig to note the current ip address of the internetcard on a piece of paper (in case you want to change it back). Then you enter an address in the range 192.168.0.xxx (where xxx can be anything (except ofcourse 2 because that is the address of the E-block) as new ip address for the networkcard per the instructions on the pdf.

In the teachers notes on the internet kit this procedure is described correctly, in the pdf that comes with the E-block it isn't.

Anyway, it's working!
