If the total current is more than the safe current capacity of the NMEA 2000 cabling (3A for all Digital Yacht cables) then the cable could melt or even cause an electrical fire. The volt drop from one end of the network to the other, must be less than 1.5VĪ key consideration in any good NMEA 2000 network design, is the total current that the network is consuming.Total length of all drop cables must be less than 76m.The NMEA 2000 backbone must be less than 100m.Maximum number of 50 physical devices on the network.The NMEA 2000 Supply current must be less than 3A (60 LEN).The NMEA 2000 Supply voltage must be between 9V and 16V.The network must be properly terminated only two terminators fitted one at each end of the backbone.The list below, gives you all of the key NMEA 2000 networking rules that, if followed, will ensure your NMEA 2000 network works correctly. The part number is ZDIGN2KIT and if you want to find out more about the Digital Yacht NMEA 2000 Starter Kit, please click here.īelow is a diagram showing how the two NMEA 2000 devices above, can be correctly connected together using the NMEA 2000 Starter Kit. An NMEA 2000 Starter Kit is a cost effective way to build a small, expandable network.There is a small cost in setting up the network, but future expansion is very easy.Some smaller low power devices, like sensors are also powered from the network.Each device has an NMEA 2000 interface that must be powered from the network.You cannot just plug two NMEA 2000 devices together with a suitable NMEA 2000 cable – they must be connected to a properly constructed NMEA 2000 network. * Note – Some manufacturers have created their own “flavours” of NMEA 2000 with different connectors and cabling Raymarine’s “SeaTalkNG” and Simrad’s “SimNet” are two examples and both need proprietary adaptor cables to connect to standard NMEA 2000 networks. NMEA 2000 is a standard set of data messages, protocols and connectors that all NMEA 2000 devices must use*.NMEA 2000 allows marine electronic devices from different manufacturers to talk to each other.NMEA 2000 is the marine version of the CAN networks found in every modern car.It is not the most in-depth technical article on the subject, there are plenty of those online, but it focuses on giving you the core information you need to use the Digital Yacht range of NMEA 2000 cabling products to create or expand your NMEA 2000 network.
More information about the Voyage Recorder can be found in the Products section of our website.This guide is for anyone who is new to NMEA 2000 and wants to quickly understand the key issues in building an NMEA 2000 network. In the second example we have shown how determinate predominant wind direction and build a wind rose.

( PDF format, file size is 2.54 MB) and plot a polar diagram for your boat. In first our case, "How to plot a polar diagram for a yacht", we demonstrate the principles of building a polar diagram using data that was collected not during special-purpose trials,īut simply some appropriate data collected by the Voyage Recorder YDVR-03.

We have prepared two cases that demonstrate how to analyze the wind conditions of your voyage and to plot a polar chart for your yacht using Microsoft Excel. Vessel's track and extensive information about the sailing conditions including weather, depth, engine, and even tracks of nearby vessels with AIS.Īfterwards, you can analyze data collected by the Voyage Recorder YDVR-03 using Microsoft Excel, for example.

The software is installed on your personal computer (the YDVRCONV program that comes with the Recorder is available free of change and runs on Microsoft Windows, Mac OS X and Linux.
The Recorder writes all NMEA 2000 network data into the memory card.
You can to use Voyage Recorder to keep GPS points, wind, depth, temperature, AIS and all other data which flow through the network backbone and are collected during your voyages over a season. We have prepared two cases that allow you to analyze wind conditions and plot a polar chart for your yacht using Microsoft Excel.
