IEC 61162
Encyclopedia
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 (WG6) of Technical Committee 80 (TC80) of the IEC.
The 61162 standards are all concerning the transport of NMEA
sentences, but the IEC
does not define any of these. This is left to the NMEA Organization.
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.
The historical background and justification for LWE was presented at the ISIS2011 symposium.. An overview article of LWE was
given in the december issue of "Digital Ship"
International Electrotechnical Commission
The International Electrotechnical Commission is a non-profit, non-governmental international standards organization that prepares and publishes International Standards for all electrical, electronic and related technologies – collectively known as "electrotechnology"...
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 four parts:- Part 1: Single talker and multiple listeners (Also known as NMEA 0183)
- Part 2: Single talker and multiple listeners, high-speed transmission
- Part 3: Serial data instrument network (Also known as NMEA 2000)
- Part 4: Multiple talkers Multiple listeners (Also known as Lightweight Ethenet)
The 61162 standards are all concerning the transport of NMEA
NMEA
NMEA 0183 is a combined electrical and data specification for communication between marine electronic devices such as echo sounder, sonars, anemometer, gyrocompass, autopilot, GPS receivers and many other types of instruments. It has been defined by,...
