Raymarine SeaTalk extension cable 5m D286

SeaTalk / SeaTalk1

Raymarine's proprietary network design released at the same time as NMEA0183 that had several key advantages. SeaTalk1 is included in many Raymarine MFDs and instruments to provide legacy support but now NMEA 2000 offers several advantages over SeaTalk1.

Data

A multi-talker, multi-listener approach using serial data at low data rates (4.8Kbps).

Cable System

The network used proprietary cables and connectors that were designed for the marine environment. The connectors are three pin moulded and incorporate 1/8 automotive spades as mating elements. The network could be implemented as either a simple daisy chain structure or the more robust approaches of backbone/spur or star design.
