overview

Terminology

Raymarine produces SeaTalk, SeaTalk

and SeaTalk

proprietary bus systems. In

this book, in the interests of clarity, SeaTalk is referred to as ‘SeaTalk(1)’.

Connectability

Specific Raymarine products (e.g. ST70 instruments) perform a bridging function, to

enable you to connect SeaTalk

to SeaTalk(1) products via appropriate adaptor

cables. Adaptor cables are also available to connect NMEA2000 products.

1.2 Hardware

SeaTalk

comprises a single backbone terminated with two terminators, one at each

end. Spur cables connect the backbone to individual SeaTalk

products.

Small diameter cable connectors are used throughout the system, to make

installation easier. Cables and connectors are color-coded to reduce the likelihood of

misconnection.

A wide range of different cable lengths provides flexibility and obviates the need for

cutting and splicing cables.

Three-way, five- way and in-line connection pieces are available to connect cables, to

deploy SeaTalk

as required.
