Can a Type 100/300 Autopilot Course Computer be interfaced to a ST-STng Converter?

Raytheon/Autohelm autopilot course computer designs such as the Type 100/300 Autopilot Course Computer (see photo below), ST4000, and ST5000 supported an earlier version of SeaTalk communications protocol than did the Raymarine autopilot course computer designs having a SeaTalk communications interface which succeeded them (ex. Type 150, Type 400, ST4000+, ST5000+, S1/S1G, S2/S2G, S3/S3G, SPX5/10/30, etc.).



Due to the differences in these versions of SeaTalk communications protocol, it is not recommended that a SeaTalk to SeaTalkng Converter be used as a data bridge with these Raytheon autopilot course computers. Instead, it is recommended that such Raytheon autopilot course computers be interfaced to the system via NMEA 0183 communications protocol. Should the system to be interfaced to not feature a MFD having a NMEA 0183 communications interface and have a SeaTalkng / NMEA 2000 backbone, then it would be recommended that a NMEA 0183 to SeaTalkng / NMEA 2000 data bridging device (ex. Actisense NGW-1-ISO-STNG, etc.) be used to interface the autopilot to the SeaTalkng backbone.
