IEC 61162 is a collection of
IEC
The International Electrotechnical Commission (IEC; ) is an international standards organization that prepares and publishes international standards for all electrical, electronic and related technologies. IEC standards cover a vast range of ...
standards for "Digital interfaces for navigational equipment within a ship".
The 61162 standards are developed in Working Group 6 (WG6) of Technical Committee 80 (TC80) of the IEC.
Sections of IEC 61162
Standard ''IEC 61162'' is divided into the following parts:
* Part 1: Single talker and multiple listeners (Also known as
NMEA 0183
NMEA 0183 is a combined electrical and data specification for communication between marine electronics such as echo sounder, sonars, anemometer, gyrocompass, Self-steering gear, autopilot, GPS receivers and many other types of instruments. It has b ...
)
* Part 2: Single talker and multiple listeners, high-speed transmission
* Part 3: Serial data instrument network (Also known as
NMEA 2000
NMEA 2000, abbreviated to NMEA2k or N2K and standardized as IEC 61162, IEC 61162-3, is a plug-and-play communications standard used for connecting marine Sensor, sensors and display Unit of measurement, units within ships and boats.

* Part 450: Multiple talkers and multiple listeners–Ethernet interconnection (Also known as Lightweight Ethernet)
* Part 460: Multiple talkers and multiple listeners - Ethernet interconnection - Safety and security
The 61162 standards are all concerning the transport of

This subgroup of TC80/WG6 has specified the use of Ethernet for shipboard navigational networks. The specification describes the transport of NMEA sentences as defined in 61162-1 over IPv4. Due to the low amount of protocol complexity it has been nicknamed Lightweight Ethernet or LWE in short.
There are three revision: the original published in 2011, and updates in 2018 and 2024.
IEC 61162-450/460
IEC 61162-460:2015(E) is an add-on to the IEC 61162-450 standard. This standard extends the informative guidance given in Annex D of IEC 61162-450:2011. The first edition was published in August 2015.
State May 2016 is the first bridge and system manufacturers beginning with the implementation of IEC 61162-450 and IEC 61162-460.
IEC 61162-460:2024 (also referred to as IEC 61162-460 Edition 3.0) is an updated add-on to IEC 61162-450. This standard extends the informative guidance given in Annex D of IEC 61162-450:2011. The third edition was published in April 2024.
