Stowe Dataline to Raymarine ST4000+

[robbieg]

Anyone know whether its possible to interface these so that I can get wind data via NMEA from the Stowe databox to the Raymarine autopilot? The Stowe manual suggests that its transmitting NMEA down the data cable & so presumably it should be possible but I'd be interesed to hear from anyone who has actually done it.

Never done it but seem to remember that raymarine use there own 'code' so a converter/interface box is needed from raymarine. Looking in the raymarine book you will possibly need a SeaTalk/NMEA/PC interface box part number E85001.

I have known to be incorrect on many occasions so check else where .....

I have exactly the same set up with Autohelm 4000 and Stowe Dataline and it all works fine without an interface box.
You can also send GPS data to the autohelm to operate in track mode but the GPS must be connected via the Dataline system.

Banjo,

Interesting-have you any idea which wires you take from the dataline box to get the NMEA data? There five seperate wires in the data cable-red & black which I assume are the pos/neg power cables and then white,green & I think (from memory) yellow-not sure which ones to connect up to the raymarine autopilot.

Dataline wiring...

As you guessed, red and black are the 12v power. White is NMEA +ve, green is NMEA -ve. The brown wire carries the signal to tell other displays what lighting level to use.

Re: Dataline wiring...

Thanks-really helpful. I'll give it go & see if I can get the data up on my autopilot this weekend!

Yes it works. Just connect the NMEA out of the dataline to the NMEA in of the pilot.
However dont expect the winddata on the seatalk bus. It does not replicate it there.
(They won to sell the converter boxes as well /forums/images/graemlins/tongue.gif /forums/images/graemlins/tongue.gif . If you want to utilize what goes in via NMEA on the Seatalk you need the Raymarine or an aftermarket converter box.

Hi I am attempting to integrate the signal from the databox into a usable nmea for the rays.
I have two questions:
- what converter box are we talking about? would it need only if connection to a ray autopilot or you mean generically on whatever seatalk bus? I was thinking to send it to a tridata and then to the autopilot.
- To connect can i run a cable in parallel from the databox or do I have to take it from the dataline instrument?

Hello @gava You are replying to a thread that is 14 years old. The posters may have gone to the great sea in the sky. Best course of action is to contact Stowe, they should know what their products can do.

I changed from Stowe to Garmin 2 years ago as the kit was falling apart after 35 years.

i know but you never know...but instead of doing a new thread...
I agree I would love to change my stowe equip, but at the moment I cannot change the stowe speed transducer housing, and seems there are no paddlewheel dia 34mm that are compatible with the trough hull housing .
therefore i have to keep it and integrate the stowe data from the databox with my others equip.
