Generate Wind “VWR” NMEA 0183 data set for tiller pilot
Hello everyone,
I am desperately trying to supply my Raymarine ST2000 tiller pilot with wind data (i60).
According to the manual, it requires the wind data via NMEA 0183 as a “VWR” data set. The serial connection is not the problem because the route control is already working perfectly.
When I generate “VWR” in Signal-K using the “SignalK-to-nmea0183” plugin, I can see it correctly in the log:
Aug 25 12:24:38 2025-08-25T10:24:38.421Z @signalk/signalk-to-nmea0183 $IIVWR,0.00,R,12.50,N,6.43,M,23.15,K4B
Aug 25 12:24:38 2025-08-25T10:24:38.522Z @signalk/signalk-to-nmea0183 $IIVWR,0.00,R,12.50,N,6.43,M,23.15,K4B
The serial interface is configured in AVNAV (plotter software like OpenCPN). However, I do not see the generated VWR data in the “AVNAV_NMEA0183” connection. I should be able to see the data records here, shouldn't I?
I am using an AVNAV standard image and have not changed anything in the connections so far. AI claims that the checksum is incorrect, but I find that unlikely. I think it is more likely to be due to my configuration. Can anyone assist me?
