Route info to Raymarine via seatalk

[jimseng]

Hello All
I regularly send route info to the autopilot (Raymarine st60+) from OpenCPN via nmea (wifi miniplex) I also have the Seatalk info coming back in to OpenCPN and car read the boat's data. I cannot, however send a route from OpenCPN to the autopilot using seatalk. Should this be possible? Is there some sort of formatting issue? I was hoping to ditch the NMEA bus and stick with seatalk but the autopilot screams "no data" at me when I disable the NMEA output.

Cheers.

The nmea0183 commands are basically one waypoint at a time, just as a regular chartplotter does. Opencpn feeds the active route one wpt at a time, which is normal and as expected by the autopilot.

You have it workin properly

There was a RM NMEA/SeaTalk converter, now a discontinued product, you might look for one on ebay (save the search and get an email when one comes up). Connect your PC data in and out to the converter and connect it to the ST bus and it will work.

Hi,

if you want to use seatalk you have to translate the NMEA sentences to seatalk.

You can look here: www.gadgetpool.de - Die Homepage and you´ll find a "Seatalk NMEA Bridge". I use an older model from them and it works since years in both directions.

As mentioned above, you do not send a route to the autopilot. The route is in the chartplotter (Raymarine, Garmin, OpenCPN) and you send the current waypoint, bearing, distance, cross track error, etc. to the autopilot. You do not need any converters, just connect the nmea output from CPN to the nmea input on the ST60+.

There is also no useful information that you can take from the autopilot to OpenCPN, so you do not need the reverse connection. Now, if you have other Seatalk data such as depth, wind or speed, then you need a Seatalk to nmea converter to be able to use/display that. In most cases though, it is cheaper to display the data on the autopilot head.
