Raymarine SeaTalkng Connections


Interconnection Bus for Raymarine Products


SeaTalkng is an interconnection bus for Raymarine products. Small diameter cable connectors are used throughout the system to make installation easier.


There's a wide range of cable lengths, all with over-moulded plugs, so there is no need to cut or splice cables. Spur cables connect individual SeaTalkng products to the SeaTalkng backbone.

Converting Sea Talk1 to SeaTalkng


Specific Raymarine products (e.g. ST70 instruments) perform a bridging function, to enable you to connect SeaTalkng to SeaTalk1 products via appropriate adaptor cables.

Adaptor cables are also available to connect NMEA2000 products.

ST1 to STNG(1)    







SeaTalkng comprises a single backbone terminated with two terminators, one at each end. Spur cables connect the backbone to individual SeaTalkng products.


Small diameter cable connectors are used throughout the system to make installations easier. Cables and connectors are color-coded to reduce the likelihood of misconnection.
