[CA] [CA11] Autopilot Malfunction

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Gustavo,


The following two items come to mind immediately:
1) Should the diagram which you have provided be accurate, then the backbone has not been properly constructed. Information concerning how a powered and properly terminated SeaTalkng / NMEA 2000 backbone should be constructed may be found here. Starting from the left hand side of our diagram,

a) the T-Piece shown should be eliminated from the diagram and replaced with an appropriate length or Backbone Cable (blue w/black stripe) or the Spur Cable (white w/black stripe) should be replaced with a Backbone Cable

b) At the lower left hand side of the diagram a 5-Way Connector is shown. This 5-Way Connector cannot be joined to the SeaTalk to SeaTalkng Converter located above in the manner show. It is recommended that the Backbone Cable which is currently interfacing the two SeaTalk to SeaTalkng Converter to one another instead be interfaced to one of the 5-Way Connector's backbone sockets and that the other SeaTalk to SeaTalkng Converter be connected to the 5-Way Connectors second backbone socket via an appropriate length of SeaTalkng Backbone Cable.

c) the SeaTalkng Spur Cable shown connecting a spur socket to the 5-Way Connector below it should be eliminated.

d) The SeaTalkng Spur Cable shown connecting a spur socket to the SeaTalk to SeaTalkng Converter on the upper right side of the diagram to a spur socket of the iTC-5 should be eliminated.

e) The unoccupied backbone socket of the SeaTalk to SeaTalkng Converter on the upper right side of the diagram should be connected to the unoccupied backbone socket of the iTC-5 via an appropriate length of SeaTalkng Backbone Cable

f) Clarification of the items labeled Plotter, Pilot, MFD, and Tri are required. I am presently assuming that MFD is actually an i70 MFID and the Pilot is actually a p70 autopilot control head.




2) The software within the all devices listed is many versions behind the currently available software. After making the corrections to the backbone described above, the software within each product should be updated to the latest version.
