Difference between S2 NMEA ports

[Chuck - Raymarine - Moderator]

Jordan,

Please note that Raymarine's autopilot's are not generally designed to function as data bridging devices. A supported data bridging is typically limited to the set of data items which are required for an autopilot to perform its functions as an autopilot. It is generally recommended that the NMEA 0183 port of a MFD or an E85001 SeaTalk to SeaTalkng Converter (retired) be used for such data bridging purposes. With respect to the NMEA 0183 ports of a S2, S2G, S3, and S3G Autopilot course computer, only heading and rudder angle NMEA 0183 sentences are transmitted from the course computer's Port 1 OUT port.
