10 10 NMEA Standards NMEA 2000 Digital Interfaces NMEA 2000 Standards Committee established in 1994 Developed by more than 40 academic, industry and international collaboration Academia - Kansas and Oklahoma State, networking and computer industry, marine electronic companies, U.S. Coast Guard Research & Development Center Multi-national marine electronics committee under NMEA guidance 5 years in development

11 11 NMEA Standards NMEA 2000 Digital Interfaces CAN (Controller Area Network) was chosen as the fundamental protocol (Bosch and Intel) Proven, robust, noise immune, distributed real-time communications, bus arbitration, priority messaging 1986 adopted by SAE J1939 (Society of Automotive Engineers) Adopted by ISO for agricultural machinery Beta tested 18 months under NMEA guidance U.S. Coast Guard Marine Electronics Manufacturers Furuno USA, JRC, Litton Marine, Navionics, Northstar, Raymarine, Simrad, Teleflex, Trimble, Wood Freeman CAN Manufacturers Kvaser, Vector Can Tech 2001 commercially viable in U.S adopted by IEC ( )

12 NMEA NMEA Standards NMEA 2000 Digital Interfaces NMEA 2000NMEA 0183 Built for networkingSingle talker, multiple listener Standard cables & connectorsBare wire connections All devices can access all network data Limited network data access Data is prioritizedData is not prioritized Gateway needed for PC connection Direct connection to a PC serial port Operates at 250k Bits / SecondBandwidth limitations (4,800 & 38,400)

13 13 NMEA Standards NMEA 2000 Digital Interfaces Message Database Architecture Follows International Standards Organization (ISO) Convention The NMEA 2000 standard is based on ISO parts 3 and 5, which is harmonized with SAE J1939. The conventions regarding bit and byte numbering are following ISO and used by SAE J1939 and NMEA 2000 standards. Auto Addressing Bit by Bit Arbitration Priority messaging embedded
