ST2000 and TackTick NMEA 0183 Problem

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Colin,

Looped NMEA 0183 data may be responsible for the reported issue. In interfacing the equipment specified, it would typically be recommended that the NMEA 0183 output of the TackTick system and third party chartplotter be interfaced to a NMEA 0183 Multiplexer. More specifically,
- the NMEA 0183 output of the third party chartplotter would be paralleled to provided data from the chartplotter to the VHF radio and to the NMEA 0183 multiplexer.
- The output of the NMEA 0183 multiplexer would be directed to the autopilot's NMEA 0183 input port.

Interfacing the equipment in this manner would support permitting the autopilot to steer to wind, steer to a user configured heading (Auto Mode), or operate in Track mode.
