S1G Fluxgate Compass Alignment Drifts - Use External Compass?

RE: S1G Fluxgate Compass Alignment Drifts - Use External Compass?
Welcome to the Raymarine Forum Bill,

The data rate for heading on the SeaTalk, not to be confused with SeaTalkng, bus is 1Hz. Accordingly, a SeaTalk source of heading data would be too slow for the S1G. In this case, it would be recommended that
- the fluxgate compass be disconnected (all leads) from the S1G
- the 4800 BAUD NMEA 0183 10Hz output (heading-only) of the third party heading source be interfaced to the S1G's NMEA 0183 input port 1.
- should drift continue to be observed, then the S1G's gyro should be unplugged from the S1G's circuit board.
