thru the fluxgate
input. Any suggestion?
I have been able to verify that STxxxx pilots with Seatalk1 course units can operate with heading data via the Seatalk1 bus, if the fluxgate is completely disconnected.
You can do two things to make your SI-TEX Vector 3D work
1) - Install the NMEA0183 / NMEA2000 converter from the antenna
manufacturer + the Raymarine Seatalk
/ StkNG converter.
2) - Install a generic NMEA0183 / Seatalk1 bidirectional gateway (ShipModul, Ocenav, Actisense,...). This solution will be more economical.
