[CA] [CA11] Raymarine SPX10 / ST8002 to Garmin NMEA Network?

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum chkjk,

Unlike the Evolution autopilots, it is not recommended that SPX autopilots be connected as spurs to a NMEA 2000 backbone. The proven method of interfacing SPX autopilots to Garmin systems has been to interface the NMEA 0183 terminals of the SPX autopilot course computer to an Actisense NGW-1 NMEA 0183 to NMEA 2000 data bridge. The NMEA 2000 dongle of the Actisense NGW-1 would then be interface to a spur socket within the powered and properly terminated backbone to which the Garmin system has been interfaced. The ST8002 must be connected directly to the SeaTalk port of the SPX autopilot course computer.
