NASA AIS engine to Garmin chartplotter

[Joker]

I have a spare NASA AIS engine; a friend has a Garmin chartplotter. I am going to try to interface the two.

The NASA AIS puts out data at 38,400 baud.

THE Garmin 551 is less explicit in its interfacing, though it does say that it 'NMEA High Speed ... supports the input of standard 0183 data for most AIS receivers'.

Will they be compatible? Anyone any experience?

Yes, and you'll have to set the Garmin's Comms to NMEA High Speed. I imagine this will make the NMEA output high speed too, which could be a problem if you're feeding position data from the Garmin to a DSC radio.

NMEA High Speed will be 38,400 baud and therefore compatible with the NASA AIS Engine.

Does the 551 have a second NMEA Serial port (some units in this series do)? If so, this can be used for the DSC, if required.

can you please enlighten the dumb: will you actually need a different wiring set up from the GPS to the DSC (the second serial port) or is it just set up from the software

(I have had lots of problems getting the three to talk!)

Page 50 of the Manual states how the 2 ports can be configured independently.

Page 6 of the Installation Manual gives details of the cable colours for the 2 NMEA Ports.

What specifically was the problem when trying to get the 3 units to talk to each other?

Thanks for the replies - I think I'm going to have to put them together and see what happens!

Worked for me without any trouble, exactly the same setup.

I'll be lucky if things go as well as that! On the topic, would I be correct in thinking I need to use pin 3 on the serial cable as Transmit data and pin 5 as signal ground?
