Check which NMEA 0183 version is used by the Simrad Dataline equipment. If
e.g. the NMEA sentence for depth is the older DBS, it may well be that the
C80 does not recognize it, because the C-series expect NMEA 0183 Version
3.01. The depth sentence for version 3.01 is DPT. Similar incompatibility
may exist for Wind data sentences (old VWR/VWT sentences).
If you had used a Brookhouse multiplexer, you could have converted the older
sentence types to version 3.01 in the multiplexer.
Another possible cause may be that the Simrad equipment does not add a
checksum to the sentences. Again, this can be added by a Brookhouse
multiplexer.
You cannot attach files to NG postings, but you can send your NMEA data file
to my email address and I'll have a look.

Thanks!
I am going to play around today and try to find a solution. I have
sent you the file per mail.

Finally I did not succeed to find a solution, Support from Raymarine
and Holland Nautic were very unsatisfying! I found a solution by using
a NMEA-SeaTalk interface.
