![]() More hooking up Legacy Equipment to this network later. Even hooking in a new device is relatively easy. Read the link above for the do's and don't's. All you need is the right parts/cables/terminators and follow some simple rules. The Nmea 2000 Backbone is pretty easy to set up as you can see from the diagram. ![]() I'll attempt here to explain some of the data networks and how to connect various different types. Here's a good primer for constructing NMEA 2000 networksĪnd Power and Motor Yacht has an article worth reading " A Breakdown of Protocol: How a Boats' System Converse" Compared with NMEA 0183 in “RS422” interface, NMEA 2000 has better transmission reliability and shares data easily in a network. It simplifies the connection and shares information among different devices by using a single trunk cable. The NMEA 2000 transmits data through Controller Area Network (CAN bus). Most of the new instruments for boats are now coming out with NMEA 2000 ( National Marine Electronics Association) as the preferred method of connecting various devices on a boat.
