CAI302 altitude in NMEA..

Uncle,
* * * * it is very easy for me to check values once I have an *NMEA stream
of a couple of minutes with valid data in it, coming from the device I would
like to support.
It's the only safe method to solve things and make them work. Since in the
LK8000 project there are no more simulations but only real feed of real data
to the software, I am looking for the CAI302 NMEA stream.

Maybe you can help me?

There is no need to adjust for standard pressure the !w QNH altitude,
since
PCAID is supposed to do that automatically.
This is what I understood.

I think the PCAID message is RAW pressure altitude, uncompensated for
anything.
Darryl,
* I have this .pdf:
*Cambridge Digital Direct Vario (302)
Data Port User’s Guide SV-517 Revision 2.2

Do you know if this is current? *(Wouldn't think it would change much,
but...)
Paolo,
If you don't have it, I'll send you the above .pdf.

I think I offered a pretty good explanation already. If a C302 is
connected why would you not want to use the w! sentence data? If you
have a C302A then you have a lot less to play with and no choice, and
you have to deal with altimeter correction in the application/UI.
Which since you are displaying it anyhow you might as well integrate
into showing the QNH from the !w sentence when connected to a 302.
