NMEA Connections to ST2000+

Welcome to the Raymarine Forum RiverRunner,

Raymarine autopilots are not designed to follow a track. However, should a compatible chartplotting product receiving GPS data be interfaced to the autopilot's SeaTalk or NMEA 0183 communications interfaces, then commanding the chartplotting product to go to a waypoint / cursor position or to follow a route may then permit navigational data to be transmitted to the autopilot. When receiving such navigational data from a compatible chartplotting product, the autopilot may be commanded into Track mode (pressing +10 & -10 buttons simultaneously). The vessel must be located within 0.1nm of the course line and/or within 5 degrees of the bearing to the next waypoint/cursor position when commanding Track mode to be entered.

Should you have satisfied the items specified above, the it is recommended that you try connecting the autopilot's NMEA 0183 IN- terminal to the Garmin plotter's ground lead rather than employing the jumper which you have installed. Should the autopilot still not be able to enter Track mode, then the following information will be required:
- the make & model of third party chartplotting product
- a 10 second data capture of the chartplotter's 4800 BAUD NMEA 0183 output taken directly from the NMEA 0183 IN+ and NMEA 0183 IN- terminals of the autopilot.
