NMEA 2000

Purpose: To Provide Assurance that NMEA 2000 Products

Interoperate Cooperatively

NMEA 0183 No industry Certification

IMO Requires Manufacturers to Submit Their Products to an

Independent Test Organization for Type Approval

Manufacturer Tests NMEA 2000® Products Using a Common

Test Tool and Submits Test Results to NMEA for Validation

Product Certification• All products are certified

• Minimum mandated requirements

• Behave in a known and predictable manner

• Expose any flaws or weaknesses in the protocol implementation

• Certification tool• Hardware: CAN interface device for a PC

• Software : test procedure as in Appendix C

• 40 manual tests

• 60 automated tests in 25 functional categories

IEC 61162-3 is NMEA 2000• NMEA and IEC TC 80 Working Group 6 collaborated

to meet the specific SOLAS requirements• Redundant network interface circuits

• Dual network

• IEC 61162-3 Redundancy Example (1)

• IEC 61162-3 Redundancy Example (1)

• 2013 Work Completed:• Power Generation - Power Distribution • Water Maker PGN• Man Over Board PGN• Channel Source PGN• Heartbeat PGN

• Works in Progress:• New Regional GNSS Systems

• China:BeiDou Navigation Sat System• India: Regional Nav Sat System (IRNSS)

Geo-Augmented Nav System (GAGAN)• Japan:Quasi-Zenith Satellite System (QZSS)

• Heave Message• Safety Net Message• COSPAS-SARSAT requirements

Internet Applications

NMEA StandardsNMEA OneNet

• Draft Standard / Not for Publication• NMEA 2000 (NMEA Network) Messages over IP

• Provides Common Infrastructure• Standard Ethernet Protocol (IEEE 802.3) • Utilize Standard Internet Protocol (IP) Addressing

•IPv6

• DOES NOT REPLACE NMEA 2000• Compliments NMEA 2000

NMEA StandardsNMEA OneNet Digital Interfaces

• Key Features

• Speed: up to 10 gigabit – > 40,000 times NMEA 2000

• Scalability: backbones may be other media such as such as Fiber

• More Devices: IPv6 support essentially unlimited

• NMEA 2000 - 52

• More Power – POE will provide a minimum 15.4 Watts

• Video – Uses internationally recognized standards

• Utilizes NMEA Network (aka2000 Appendix B) Message Database

• Internet of Things (IoT)

Why IPv6?• Global movement underway

• Service providers IPv6 enable today

• Support of multiple IP addresses per 1 MAC Address

• More efficient addressing and routing

• Embedded security

• Enhanced quality of services

Why IPv6?• Eliminate legacy addressing issues later

• Avoid cost of dual stack implementations

• Manufacturers use “off the shelf” protocols

• Provides a platform for new and yet-to-be imagined services for vessels

• Allows OneNet to ride this wave into the future

Current Internet Applications• Discovery Services

• Simple Service Discovery Protocol (SSDP) • Bonjour (mDNS)

• Universal Plug and Play (UPnP)

• Internationally Recognized Video & Audio Standards

• OneNet Device Certification• Model NMEA 2000

• Globally recognized maritime installation standard for marine electronics• Added value for boat owners

• Quality assurance from dealers and manufacturers

• Fewer claims; fewer problems

• Better workmanship; improved reliability

• Reduction in warranty work

• Major revision work – Publishing Q 2 2014• Previous Version published 2010

NMEA StandardsNMEA 0400 Installation Standard

• NMEA Certificate Training Courses• Marine Electronics Installer Course (MEI)

• Advanced MEI Course (AMEI)

• NMEA 2000 Course• Certified Marine Electronics Technician (CMET)
