[CA] [CA11] Integrating A70 Plotter and AP ST 4000 +

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum shero2,

The MFD's Autopilot transducer status icon will only reflect the connection status of a Raymarine autopilot which has been interfaced via SeaTalk or SeaTalkng to the MFD. Additionally, wiring shown within your diagram will likely result in a data loop. The correct method of interfacing the MFD ST60 instruments, i40 instruments, and a ST4000+ autopilot are detailed within the FAQ found here. In this case, it would be recommended that the NMEA 0183 connections between the MFD and the other Raymarine products be disconnected. The ST60 Multi would be connected to the SeaTalk (yellow) socket of the SeaTalk to SeaTalkng Converter. Finally, and indicated within the referenced FAQ, the SeaTalk Cable which is presently connecting the ST4000+ to the D244 SeaTalk Junction Block will need to be cut and then spliced back together, leaving the cable's red leads unspliced. Instead, the cable's red leads will simply be insulated to prevent shorting.
