You are right some are outdated.

Take a look at http://vancouver-webpages.com/peter/nmeafaq.txt

That info is pretty old. More like NMEA-0183 V2 or so. V3.1 has a lot of
sentences with extra/new fields added.

Thank You, I had forgoten that only with a NMEA multiplexor I can have
more than one talker. I have the folowing situation: my gps is
sending NMEA messages to my AH autopilot, and the gps is receiving
Depth (DBT) from an Navman depth sounder. Aditionaly, I have a laptop
witch is reciving NMEA from the gps, for real time ploting, using some
software. If I add a VHF/DSC radio, sending and receiving NMEA to/from
gps, what would hapen?

My gps is a Garmin Gpsmap276C, witch now (3.1) includes a very
interesting interface with VHF/DSC, that can show the position of all
boats nearby (if they are DSC/VHF ready), so that I will see the
positions of all boats in the map screen, this would be useful in a
flotilha cruising for example,or pheraps to see ships in the scren? I
think this is not dependent of the Mayday function, witch is suported
too, but shows diferent symbols, colors and alarms.

In this case I will have more than one talker?

Thanks

Pascal

I don't know which VHF/DSC radio you have, but all the ones I have
looked at only receive GPS data. ICOM, Uniden, West Marine only have a
GPS in lead. My Garmin drives four listeners, auto pilot, Pactor IIe,
Uniden VHF/DSC and computer with Nobeltec Navigation software. The
computer is the only device that can transfer data to the GPS.

I know that the Icom M602 has both input and output.

The new Uniden UM625 and UM525 also have nmea output.

Ok, there are some VHF radios witch outputs NMEA. But what messages
are used? I know there is DSC and DSE, messages related to DSC since
NMEA version 2 . But my question was if I add NMEA IN/OUT from
VHF/DSC, and I alredy have the Depth Sounder sending NMEA to gps, the
Laptop sending and receiving to/from the gps, witch in turn sends NMEA
to autopilot and so on. How many talker I have? Would be a problem in
that case? With DSC in/out I am adding another unit sending NMEA to
the gps and, since I already have the Depth Sounder sending NMEA DBT
to the gps, this wil work?

I know that the GpsMap 3010 and GpsMap 276C both "theoricaly" have 2
NMEA ports, but at last in my one, witch is at the latest software
level (3.1) this does not work, because when I set one port to NMEA
the other is automatically set to NONE by the softwa so I can have
only one port using NMEA, the other can be Garmin mode, etc.. but not
NMEA. I think this could be a software problem, any coments? Maybe
anibody witch has a GpsMap 3010 or 3006 could tell me if this 2 port
can work "realy" in NMEA format?

In summary, anibody here is using VHF/DSC with the new Location NMEA
IN/OUT function? Anibody here has GpsMap 276C or GpsMap 3006/3010? Who
is using the 2 NMEA ports at same time?

Thanks

You always need a multiplexer when you want to feed data from more than one
device into another. So you need one to feed the output from the VHF and the
depth sounder into the GPS.
