[DG] [DG11] Can ST2000+ use external Compass?

[Derek - Raymarine - Moderator]

Hi Elau,

Thankyou for your enquiry.

The ST2000+ cannot use NMEA heading to overcome the effects of the local magnetic deviation, however, it can use Heading information on SeaTalk to compensate for this effect. the best route is to use a SeaTalk heading input from soemthing like an ST40 or ST50 or ST60+ compass instrument connected direct to its own fluxgate compass.

What happens is that the SeaTalk heading input provides the long term satble heading and compensates for the massive local deviation caused by the outboard motor, the internal fluxgate in the ST2000+ is still used by the autopilot for the very rapid short term control of the system.

I hope this helps?
