Yes SeaTalk is proprietary. It is Raymarine's version of NMEA
. They use it for communication between there primary instruments. It basically contains equivalent sentences, but the format is different. They make a small interface box that converts the data back and forth between NMEA and SeaTalk. The data on the SeaTalk side is info like wind
speed and direction, course, position, water
speed, even autopilot
Their HSB stands for High Speed Bus is Raymarines way of transmitting Very large amounts of data. It has things like Radar and chart plotter images
. There is no good way to get at this data, that I am aware of, asside from Raymarines interface.
Raymarines newest GPS
(Raystar 125) puts out both NMEA and SeaTalk Sentences. The Raystar 120 puts out either one of the two protocols. You had to purchase
the appropriate antenna
. Before that, I believe they were SeaTalk only. All recent (last 10 years or so) Raymarine equipment
will except either protocol. As a matter of fact, both protocols can be present. If the Autopilot
sees both, it will use the NMEA data and discard the SeaTalk sentences. Go figure...
More information can be found at Raymarine Marine Electronics
especially in their support areas.
If you have one of their chart plotter/Radar units, E, C or RL, you can tap the output directly into a RS232 serial
port. I believe they give wiring
instructions on their website.
You think we never stray off topic here at CF!
