MicroNet is a wireless sensor data transmission method supported by some Raymarine sensors and displays, such as the T120 masthead wind transducer and the Log + Echosounder system in conjunction with the Marine TackTick T100 display. Raymarine also offers a gateway called Micro-Talk that can convert data from the wireless MicroNet to SeaTalk NG.… Continue reading

RayNet by Raymarine

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

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


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 (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


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)

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
