Connection Problems NetDCU 8 COM2 (Interface 1)

AIF · Oct 21st 2011

Hello,

we are a group of 4 students and we got a NetDCU8 from a former project to use for our study-project, a driver-information-system for an electric formula car.

Right now we are trying to connect the NetDCU over COM2-port to enter config-mode and execute ndcucfg.exe as described in the First-Steps manual. Every time we try to connect or make a reset of the NetDCU we only get the message <-2> on the DCUterm screen.

After searching the forum a lot we decided to update the BootLoader and the WindowsCE-Kernel which seemed to work very well. If we connect to the COM1-port we can see the following text of the Windows CE Boot Loader:

But this didnt solve our problem and we still dont have any connection on the other ports.

Hello,
it looks like a connection/HW problem as you can see from debug output "ndcucfg" is running.
Maybe you can redireckt "ndcucfg" to COM1: using "WinNDCUCFG" or command line tool (CMD or Telnet). For redirect "ndcucfg" edit HLKM\System\NDCUCfg\Port = ... .

Hi,

thank you, but we have no idea how this works.
Can you make a Step-by-Step how-to guide, please?

How can we change the ndcucfg in "WinNDCUCFG"?

Thank you

Hello,

have you already read first steps document? Also in the forum you will find a lot of hints!

I did not test it but following should work. Create a txt file with following content and transmit it via WinNDCUCfg.

Code

reg open \system\ndcucfg
reg set value Port string COM1:
reg save
REM dont forget the enter

Note on COM1: the debug output is active. So you have to switch off these output before you can uss NDCUCfg. For this purpose step into the bootloader and enter "O" ... .
