RayNet is an Ethernet protocol and connector standard developed by Raymarine to connect high data volume systems. This includes systems such as plotters, cameras, radar devices, controllers for autopilots and some other systems. Raynet uses an Ethernet connection with a transmission rate of 10/100/1000 Mbit/s, which enables fast transmission of data and high-resolution video transmission in real time.

SeaTalk NG
Raymarine SeaTalk NG
Fig.: SeaTalk NG connection technology
With SeaTalk NG there is a more powerful successor to SeaTalk, which is based on the CAN bus and has limited compatibility with NMEA2000. With the fairly clear and color-coded connection technology of SeaTalk NG, Raymarine has managed to provide backwards compatibility with SeaTalk, which also supports older devices. The disadvantage, however, is the high price for the proprietary connection technology.… Continue reading
Raymarine SeaTalk
Fig.: SeaTalk connection technology
SeaTalk is a Raymarine proprietary serial network protocol developed in the 1980's and used for the transmission of navigation data and other information on boats. The data is transmitted as compact binary data. SeaTalk uses a single wire connection as the data line for serial data transmission, meaning they are both sent and received bit by bit over a single wire.… Continue reading
OneNet
NMEA OneNet is a transmission method based on Ethernet. With NMEA OneNet, as the name suggests, an attempt is made to bundle a wide variety of transmission methods such as NMEA0183 and NMEA2000 in one protocol and thus maintain compatibility with old transmission methods. In addition, new protocols are added with which large amounts of data such as image and map transmission are also possible.
NMEA2000

NMEA2000 (National Marine Electronics Association 2000) is a bus system for communication in boats. It was designed to provide a uniform interface for transferring data from electronic devices on boats.
operating principle
NMEA2000 is a bus system designed to transmit data between electronic devices on boats.… Continue reading
NMEA0183
NMEA 0183 is a marine serial communications standard. It defines a format for the transmission of GPS information, speed and course data, and other navigation data between navigation devices and other electronic devices on boats.
Benefits of NMEA 0183:
- Common: NMEA 0183 is a common standard supported by many legacy devices
- Ease of implementation: It is easy to develop a device for NMEA 0183 as there are simple protocols and a well-documented specification.
NMEA2000 for NASA / CLIPPER Duet sonar/log
First of all, a few important notes that you should definitely pay attention to.
Fig.: NASA/Clipper Duet Sonar/Log
This article is about how to convert a NASA/Clipper Duet echo sounder/log so that the device outputs NMEA2000 data. This document is based on the DIY project by Sönke and was supplemented with some additional information. The NASA/Clipper Duet echo sounder/log is actually a device without a bus connection and works independently with two separate sensors.… Continue reading
Maritime Data Server (MDS)
Fig.: MDS dashboard
The MDS – Mmaritime Data Server was developed to store and display boat data.
Which data can be saved?
During development, emphasis was placed on having a system that was as flexible as possible. The MDS is currently prepared for temperatures, voltages, GPS values, pressure and humidity, digital values, etc. Further data can be created by defining sensor types in the database.... Continue reading
Data integration in Ubidots
The flow of configuration for data integration in Ubidots looks like this:
- Login to Ubidots
- Create a plugin for webhook at Ubidots
- Set up webhook at TTN V3
- Checking the webhook functionality
Set up Ubidots login and plugin for webhook
In order to be able to transfer the received LoRa data from TTN to Ubidots, we need a plugin for data reception for a webhook Set up in Ubidots.… Continue reading
Hardware basis for AVnav and OpenPlotter
First of all, a few important notes that you should definitely pay attention to.
Raspberry Pi
The main hardware base for AVnav and OpenPlotter is the Raspberry Pi. It is a small computer in credit card format. It is available in several variants, although we are only concentrating on the Raspberry Pi 4B here. Of the older models, only the Raspberry Pi 3B is still interesting.… Continue reading
