SeatalkNG to S1 course computer

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Ted,

The S1/S1G/S2/S2G/S3/S3G Autopilot Course Computer designs succeeded the Type 150/150G and Type 400/400G Autopilot Course Computer designs and would therefore be deemed compatible with SeaTalk to SeaTalkng Converters which have been updated with the latest SeaTalk to SeaTalkng Converter software. While it would be possible to interface these autopilot course computers to the new MFD via NMEA 0183 communications protocol, one would not typically do so, as it would prohibit use of the Autopilot Control feature of the a/c/e/eS/gS-Series MFDs. Accordingly, it is recommended that all five devices having a SeaTalk communications interface be interfaced to a common SeaTalk bus, which is in turn interfaced to the yellow socket of the SeaTalk to SeaTalkng Coverter.

Your diagram incorrectly shows the SeaTalk bus being powered from the distribution panel through the instrument display. Power should not be provided to the instruments in this manner. If interfacing the S1 to the SeaTalk bus as described above, then it is recommended that the red lead of the SeaTalk Cable connecting the SeaTalk bus to the autopilot course computer be disconnected and then insulated to prevent shorting.

Additionally, should the MFD not be installed in a location affording it an unobstructed view of the skies overhead, then it would be recommended that the NMEA 0183 output of the RS125 GPS Sensor additionally be interfaced to the NMEA 0183 input of the MFD.
