Re: [foxboro] REPLACE DNBI WITH DNBT

Is this a single node system? 
If not, moving the AW70 to another cellbus to make it closer to operations may 
have put it into a different node with a different NSAP.
 
Also in Event Viewer if the machine does not see the DNBT you will see an error 
messeage:
DNBI initialization failed. (same message no matter what interface)
If you do not see that message and you still are not connecting to node..then 
it is a configuration issue.

Barry

Thanks for your help......

I am using the splitter cable (P0971YQ) on the AW70 and I raised the
elevator. I know the cables and DNBT are OK, because I tested them with a
spare AW, 1 x 8 mounting structure and a comm processor.

I now think that perhaps there may be some issue with the 1 x 8 mounting
structure. It was installed back in 1999 and maybe there´s some
compatibilityproblem with the DNBT...... though I found no reference to such
problem on the documentation CD.....
