Thanks abarrow. The second link to the NMEA sentences is quite interesting. I wasn't able to make any sense out of the other link.
Yes, I am feeding various data into openPlotter and from there I am feeding the data to the chart plotter. I do not need to talk directly to the Seatalk bus because the chart plotter is hopefully translating it's NMEA 0183 input onto the Seatalk bus. The idea is to add a NMEA sentence to the data to cause the autopilot to go up or down in the heading.
