[CA] Adding STNG and N2K to exisiting Seatalk

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Grant,

Your proposed new system diagram is correct in how the SeaTalkng backbone will be powered except for one item ... the SeaTalk port of the C-Series Classic MFDs produces power. Accordingly, the red lead of the SeaTalk cables which are connecting the C-Series Classic MFDs to the SeaTalk bus will not be used. This may necessitate cutting these cables and then splicing two of the cables leads back together, leaving the cable's red leads unspliced and insulated to prevent shorting.

Please note that the C-Series Classic MFDs are exclusively designed to process AIS data received via the MFD's NMEA 0183 port. Accordingly, should the AIS receiver/transceiver shown within your diagram feature a NMEA 0183 communications interface, then it should be interfaced to the input leads (yellow and brown) of the MFD's NMEA 0183 Cable and the MFD's NMEA 0183 port should be configured for 38400 BAUD NMEA 0183 communications (AIS 38400).

The MFDs will need to be powered via their respective power cables. The ACU will need to be powered via its power terminals.

Finally, it is recommended that the SeaTalk to SeaTalkng Converter be updated with v2.03 software. As it is not possible to update SeaTalkng devices via a C-Series Classic MFD, it would be recommended that it be updated by your dealer or by Raymarine's Product Repair Center.
