Hi Techstyle.  Another option would be to find a Raymarine ST60 Multi instrument.  It has "Seatalk 1", "NMEA In", and "NMEA Out" plugs on the back and it will convert some data from Seatalk 1 to NMEA 0183 and other data from NMEA 0183 to Seatalk 1  See below for sentences.  


From the ST60 Multi Instrument Owner’s Handbook
 
1.6 Operating with NMEA
The ST60 Multi instrument can provide data communication between SeaTalk
and NMEA when the appropriate connections are made, and supports NMEA
0183 compatible products.
SeaTalk to NMEA 0183
Data from SeaTalk is transmitted to the NMEA output port every 2 seconds. The
data types and NMEA headers are:
        Data                                                                 NMEA Header
        Depth                                                                         DBT
        Heading, deviation and variation                               HDG
        Magnetic heading                                                      HDM
        Water temperature                                                     MTW
        Water speed and heading                                          VHW
        Wind speed and angle                                               MWV
 
NMEA to SeaTalk
The ST60 Multi instrument decodes certain data from NMEA when available, and
if the respective data is not already present on SeaTalk, transmits the decoded
data to SeaTalk. The data types and NMEA headers are:
 [b]       Data                                                                 NMEA Header[/b]
        XTE, Waypoint identifier,
        Bearing & distance to waypoint                                    APB

        Bearing & distance to waypoint                                    BWC
        Bearing & distance to waypoint rhumb line                  BWR
        Latitude and longitude                                                  GLL
        Time, latitude, longitude, satellites tracked & HDOP    GGA
        Cross track error                                                           MWV or XTE
        Navigational information                                               RMB
        Time, date, lat, long,                                                     COG & SOG RMC
        COG and SOG                                                              VTG

This one can make the work? https://www.painestore.it/convertitore_s...vMEALw_wcB

Something cheaper exists?



I though it was 1 camble for wind and 1 for depth... But i never check. Next time i will

Hi, you should use this. It's also cheap ... good wind!  Shy
Http: //yakbitz.com/ST1toNMEA.aspx
Finally today has arrived the stuff to convert nmea1 signal.
I try it immediatly. Connecting it to my pc, it doesn't recognize it... It's becouse there are nothing attached?
Becouse of corona virus restriction i don't think i can go to my boat in a short time to connect it to my instrument, how can i check if everything works?
There's some drive i have to install? I searched via google but i can't find any information...

Ciao, in OP you have to go to Serial and add the new port. Obviously, if there are no Setalk instruments attached, nothing will happen. The new door, however, you should also see it in signalK ready for use! Not being bidirectional, it is not a good idea to add the autopilot. Smile 
And stay in the house, the time will come to try everything on the boat as soon as the war with the virus is won! Angry

Good morning,
Finally i'm making step forward to the configuration.
Now it seem i have a porblem with the cable from the instrument to the converter.
As i pay no so little money for the cable i have some question before trying some solutions.

What happen
I check the electricity with a tester and there's some result in the data cable with changing values. This mean that some signal is arriving.
In the 12 volt cable (the red one) there isn't electricity, and the converter doesn't work
If i move the connector on the autohelm side the converter start working and data flows.
So i supposed the problem is with the contact of the 12 volts in the connector.
Is it correct?

Question:
Can i take the 12 volts from another source (instrument panel i.e.) directly without changing the connection from the autohelm or I'm going to damage the converter?

I try to find another 3 pin round plug to change directly the one in the cable but i can't find a compatible one. Anyone knows what kind of plug is?

you may want to look at this:

I haven't tried this personally but this llike it may work and I am going to try the ones listed below:

https://www.mouser.com/ProductDetail/Con...witchcraft  looks like the 3 connector Female (socket) version @ $8.88

https://www.mouser.com/ProductDetail/Con...witchcraft looks like the 3 connector Male (Pin) @ $5.21

Questions to others:

are the Yakbitz products plug and play with OP2? or is there a guide to adding one? I am especially thinking about the USB version

Yakbitz is plug and play. You just have to configure the port in OP2.

Tried these connectors and only the male pin one works, the female one does not. I will try to find the mating connector to this one

Thank you techstyle, in the meantime i have checked the plug. And the cable with the problem was the 12 volts cable and i take the power for the converter from another source.
I don't like this solution but till i find the correct plug (female) i can use it.
Buon vento

Might it be possible that OpenCV might play a gateway role here? Attempting to integrate things at a native protocol level is obviously hard. In a case like this where output is already being displayed visually, wouldn't it be possible (and much easier in the long run) to train a camera (a cheap CCD would suffice) on the instrument and perform the conversion is OpenCV? https://github.com/opencv/opencv
