Originally it was NMEA 0180 and NMEA 0182, which primarily dealt with the transfer of data between the LORAN and the autopilot. Rather than having each manufacturer come up with their own methods of interconnecting marine electronic equipment, NMEA aims to standardise the approach. Others need to send positional data from the GPS to the VHF, or from the echo sounder to the chart plotter. For example, older systems needed to send positional data from the LORAN to the autopilot. Marine equipment needs to be interconnected to transfer data between systems. Manufacturers, dealers and other parties are members of the organisation, all committed to implementing common standards across inter-connected marine electronic equipment. The National Marine Electronics Association (NMEA) is the organisation that has developed the standards and pushed for its implementation. You can think of them as the network that transfers data between equipment.
NMEA 0183 and NMEA 2000 are different standards that are used to inter-connect marine electronic equipment on vessels. What are NMEA 0183 and NMEA 2000 used for? NMEA 0183 requires a new network for each data source because each bus can only have a single “talker”. NMEA 2000 allows all your marine electronic equipment to be connected to a single backbone, with data flowing in every direction. It has taken me a long time to research the differences, so I thought I would write this article to help out fellow navigators who are also struggling. To connect NavLink2 to the Raymarine network you will need to purchase the Female version of the Raymarine adaptor cable which is their Part Number A06045 and is very cheap.Electonic engineers are very familiar with the details and differences between NMEA 0183 and NMEA 2000, but I am a navigator, not an electronics specialist. To connect our NavLink2 unit to the Raymarine Network, it is necessary to purchase a SeaTalkNG to DeviceNet (NMEA2000) cable from Raymarine.Ĭonnecting our NavLink2 to an NMEA2000 network could not be easier as it takes power from the network and puts data on to the network via its NMEA2000 cable (0.75m) which is terminated in a standard NMEA2000 male connector. Raymarine’s version of the industry standard NMEA2000 interface, called SeaTalkNG, is fully compatible with NMEA2000, but features their own connectors and additional proprietary PGN messages. The diagram below shows how our NavLink2 would connect to Raymarine’s popular entry level A65 Multi-Function Display (MFD), the first of this new breed of NMEA2000 only chart plotters.

In this post, you can find out how to install a NavLinK2 NMEA 2000 to WiFi server on a SeaTalkNG network. Always fit the terminators on the end of the backbone.
If you are installing a larger NMEA2000 network and wish to have multiple 4 way T-Piece Backbone, they can be joined together either directly or via a drop cable (as shown below). Simply find a spare “T Piece” connector or expand the NMEA 2000 backbone and the integral NMEA2000 cable of our NavLink2 will plug straight in, taking its power from the network and sending all received data over the WiFi on navigation apps & software.Īlthough this post is about how to connect the NavLink2, you can do the same with our other products which have NMEA 2000 interface (such as our AIS transponders). The Digital Yacht’s NMEA 2000 starter kit uses the standard NMEA 2000 connector so you don’t need any special adaptor cables to connect an NMEA 2000 equipment to the NMEA 2000 starter kit from Digital Yacht. The connection system will work with all leading brands and can be expanded using standard components as required.
It’s suitable for DIY installers as well as boat builders who want an easy and value priced solution for integrating and installing modern boat electronics. Therefore allowing for a really neat and compact installation – ideal for behind the helm. The backbone is formed from a unique 6 way extension block with ports at each end that accommodate the terminators. It uses the high quality, nickel plated metal style connectors rather than the cheaper plastic type which can prove unreliable. In this post, you can find out how to install a NavLinK2 NMEA 2000 to WiFi server on a Digital Yacht NMEA 2000 network.ĭigital Yacht’s NMEA2000 starter kit allows for up to 3 devices to interconnect – say AIS, plotter and autopilot and comes complete with terminators and a power cable.
