IEC 61162


IEC 61162 is a collection of IEC standards for "Digital interfaces for navigational equipment within a ship".
The 61162 standards are developed in Working Group 6 of Technical Committee 80 of the IEC.

Sections of IEC 61162

Standard IEC 61162 is divided into the following parts:
The 61162 standards are all concerning the transport of National [Marine Electronics Association|NMEA] sentences, but the IEC
does not define any of these. This is left to the .

IEC 61162-1

Single talker and multiple listeners.

IEC 61162-2

Single talker and multiple listeners, high-speed transmission.

IEC 61162-3

Serial data instrument network, multiple talker-multiple listener, prioritized data.

IEC 61162-450

Multiple talkers and multiple listeners.
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 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 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.
