When current flows through the NMEA 2000 backbone and drop cables, a voltage drop occurs resulting in the voltage at one end of the network being different to the voltage at the other end.Add up the LEN values of all devices and make sure the total is less than 60 LEN which equals 3A.The LEN number will be printed on the devices product label (see example below).Every NMEA 2000 certified device, has a Load Equivalency Number or “LEN” for short.

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. Assign device and data instance numbers.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.Analyze the network layout for compliance to NMEA 2000 ® standards.Produce network configuration table which matches N2KAnalyzer ® format.For devices supporting multiple channels, record the following information for each channel, as applicable:.Current requirements in LEN and milli-Amps.Record of design decisions for each device on the network.Pictorial display of network layout and components.In addition, N2KBuilder ® will directly produce a Bill of Materials (BOM) for Maretron ® products, eliminating guesswork and transcription errors.
