[CA] [CA11] Interfacing Axiom 9 to St40-bidata and tillerpilot

[Chuck - Raymarine - Moderator]

Frank,

Your diagram is almost correct. The SeaTalk (yellow) socket of the SeaTalk to SeaTalkng Converter will not be connected to the ST40 instrument as your diagram illustrates. Additionally, the ST1000+ autopilot's bulkhead jack will not be connected to a spur (white) socket as your diagram illustrates.

The yellow socket of the SeaTalk to SeaTalkng Converter will be connected the SeaTalk to SeaTalkng Converter Cable supplied with the SeaTalk to SeaTalkng Converter Kit. The other end of this SeaTalk to SeaTalkng Converter Cable will be connected to a D244 SeaTalk Junction Block. The ST40 instrument will be connected to the D244 SeaTalk Junction Block via an appropriate length of SeaTalk Cable having press-fit 3-pin plugs on each end of the cable. Finally the ST1000+ autopilot's bulkhead jack will be connected to the D244 SeaTalk Junction Block via an appropriate length of SeaTalk Cable having press-fit 3-pin plugs on each end of the cable. One the cable's plugs will be removed to permit the SeaTalk Cable's leads to be connected to the ST1000+ autopilot's bulkhead jack. When connecting this SeaTalk cable to the ST1000+ autopilot's bulkhead jack, the SeaTalk Cable's power (red) lead will not be used and will need to be insulated to prevent shorting. The SeaTalk Cable's data (yellow) and ground (shield) leads will be connected to the ST1000+ autopilot's bulkhead jack as indicated with the ST1000+ Owner's guide.

Finally, circuit supplying power to the SeaTalkng / NMEA 2000 backbone's power cable should be switched.
