SeaTalk
The SeaTalk standard was originally developed by Autohelm (part of
Raymarine), and allows compatible instruments to be connected by a single
cable carrying power and data in/out. This means that additional instruments
and functions can be added to a SeaTalk system, simply by plugging them into
the network.
SeaTalk is a precise, high-speed, bi-directional protocol which is flexible
enough to adapt to any number of instruments, without a central processor.
SeaTalk equipment can also communicate with non-SeaTalk equipment via
the NMEA standard.
