Having purchased said EasyAIS, I cannot get any display on the Chartplotter. I've connected the AIS orange wire to the Black wire from the chartplotter and thence to the negative 'busbar'. The AIS white/orange wire is connected to the Chartplotter Brown wire. This was done as a result of a conversation with Garmin Support, Does it work? Does it Hell. EasyAIS unit has its own aerial and the red receive light is flickering as its supposed to. Power is available to the unit and displaying correctly. On power up the Garmin chartplotter displays that there are no connected devices.

Anybody have any ideas/solutions?
 
Did you go into the chartplotter's Comms tab and set it up for "NMEA In/NMEA Out", and also set the baud rate to 38400?

Yes, both units are set to 38400kbs. Not too sure about the NMEA In/NMEA Out bit though. I have to check. Thanks

there might be multiple comms tabs, mine has 2

I shall check that too.
 
Right then. Been down to the boat and checked the Chartplotter is set to NMEA IN/NMEA OUT (which it was already). So now I'm well and truly stuck. The pamphlet which comes with the EasyAIS unit gives no further clues and neither does the GPSMAP 292 manual.

Any other ideas?
 
Both are set to 38400. The default on the AIS is already at 38400. As for the same version of NMEA, I only know the output of the EasyAIS is NMEA 0183. They should rename the product to DifficultAIS - it would be more accurate !

The NMEA telegram is VDM
The EasyAIS
pamphlet (under Chartplotter settings) suggests that:
Select the right input channel at your Chartplotter. Some do have up to 3 or more input channels.
Set the Transmission data rate to 38400 - Done
Set the input channel to the following bit configuration 8/N/1 - (Cannot see anything on the chartplotter that allows me to do this)

The wires are as follows:

White-Orange - NMEA Out (+), AIS Data
Orange - NMEA Out (-), AIS Data.

On the Chartplotter:
Blue - NMEA Out (not used according to Garmin for this configuration)
Brown - NMEA IN (Garmin suggested this wire be connected to the Chartplotter black wire (which is connected to the negative 'busbar'

This is all the information I have.

[/ QUOTE ]This isn't what you said earlier, and it isn't right. The correct wiring is what you said earlier ("I've connected the AIS orange wire to the Black wire from the chartplotter and thence to the negative 'busbar'. The AIS white/orange wire is connected to the Chartplotter Brown wire.")

This seems a bit unfair when you have not isolated the faulty component yet. Or your connections between them. Or your parameter settings.

To test the AIS unit try connecting a computer via a serial RS232 (or through a USB adapter) and download Electrotech's NMEA Plus to display the NMEA sentences.

Be aware that you won't get any if you are not in range of any transmissions - I had to wait until I was aboard with my AIS installation before I could monitor what I was getting. Luckily my unit had an integrated GPS chip that at least passed the GPS ($GPRMD) sentences every second to test at home.
 
The white/orange wire is AIS NMEA OUT + and it is connected to the GPSMAP Brown wire (NMEA IN +)
The Orange wire is AIS NMEA OUT - and it is connected to the GPSMAP Black wire which is in turn screwed into the negative busbar.

Apologies for any confusion.
