SeaTalk
The SeaTalk standard was originally developed by Autohelm (part of the
Raytheon group), 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.
SeaTalk Connection
This connection is necessary for full functionality between HSB Series
displays.
SeaTalk data, if present, is the primary source for all navigational data except
heading.
