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 (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, autopilot, GPS receivers and many other types of instruments. It has been defined and is ...) * Part 2: Single talker and multiple listeners, high-speed transmission * Part 3: Serial data instrument network (Also known as NMEA 2000) * 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 sta ...

International Electrotechnical Commission
The International Electrotechnical Commission (IEC; in French: ''Commission électrotechnique internationale'') is an international standards organization that prepares and publishes international standards for all electrical, electronic and related technologies – collectively known as " electrotechnology". IEC standards cover a vast range of technologies from power generation, transmission and distribution to home appliances and office equipment, semiconductors, fibre optics, batteries, solar energy, nanotechnology and marine energy as well as many others. The IEC also manages four global conformity assessment systems that certify whether equipment, system or components conform to its international standards. All electrotechnologies are covered by IEC Standards, including energy production and distribution, electronics, magnetics and electromagnetics, electroacoustics, multimedia, telecommunication and medical technology, as well as associated general disciplines suc ...

NMEA 0183
NMEA 0183 is a combined electrical and data specification for communication between marine electronics such as echo sounder, sonars, anemometer, gyrocompass, autopilot, GPS receivers and many other types of instruments. It has been defined and is controlled by the National Marine Electronics Association (NMEA). It replaces the earlier NMEA 0180 and NMEA 0182 standards. In leisure marine applications it is slowly being phased out in favor of the newer NMEA 2000 standard, though NMEA 0183 remains the norm in commercial shipping. Details The electrical standard that is used is EIA-422, although most hardware with NMEA-0183 outputs are also able to drive a single EIA-232 port. Although the standard calls for isolated inputs and outputs, there are various series of hardware that do not adhere to this requirement. The NMEA 0183 standard uses a simple ASCII, serial communications protocol that defines how data are transmitted in a "sentence" from one "talker" to multiple "listeners" at a ...

NMEA 2000
NMEA 2000, abbreviated to NMEA2k or N2K and standardised as IEC 61162-3, is a plug-and-play communications standard used for connecting marine sensors and display units within ships and boats. Communication runs at 250 kilobits-per-second and allows any sensor to talk to any display unit or other device compatible with NMEA 2000 protocols. Details Electrically, NMEA 2000 is compatible with the Controller Area Network ("CAN Bus") used on road vehicles and fuel engines. The higher-level protocol format is based on SAE J1939, with specific messages for the marine environment. Raymarine SeaTalk 2, Raymarine SeaTalkNG, Simrad Simnet, and Furuno CAN are rebranded implementations of NMEA 2000, though may use physical connectors different from the standardised DeviceNet 5-pin A-coded M12 screw connector, all of which are electrically compatible and can be directly connected. The protocol is used to create a network of electronic devices—chiefly marine instruments—on a boat. Vario ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Marine Electronics Association
The National Marine Electronics Association (NMEA) is a US-based marine electronics trade organization setting standards of communication between marine electronics. Standards NMEA 0183 NMEA 2000 NMEA OneNet NMEA OneNet is a latest standard for maritime data networking based on 802.3 Ethernet, and will complement existing onboard NMEA 2000 networks by allowing for high-capacity data transfers. Current maritime data networks have bandwidth capacities of less than 1Mbit/s. Building on Ethernet, OneNet allows for capacity in the hundreds or thousands of megabits per second. This extra bandwidth is needed for transferring unprocessed sensor data from sonar/ radars, as well as video feeds from for example an engine room. The primary features and goals of OneNet are as follows: * NMEA 2000 data transfer over IPv6 in a standard format * High-bandwidth applications such as radar, video and more that are not possible via NMEA 2000 * Support Ethernet and TCP/IP at 1 gigabit and faste ...

IEC Standards
This is an incomplete list of standards published by the International Electrotechnical Commission (IEC). The numbers of older IEC standards were converted in 1997 by adding 60000; for example IEC 27 became IEC 60027. IEC standards often have multiple sub-part documents; only the main title for the standard is listed here. * IEC 60027 Letter symbols to be used in electrical technology * IEC 60028 International standard of resistance for copper * IEC 60034 Rotating electrical machines * IEC 60038 IEC Standard Voltages * IEC 60041 Field acceptance tests to determine the hydraulic performance of hydraulic turbines, storage pumps and pump-turbines * IEC 60044 Instrument transformers * IEC 60045 Steam turbines * IEC 60050 International Electrotechnical Vocabulary * IEC 60051 Direct acting indicating analogue electrical measuring instruments and their accessories * IEC 60052 Voltage measurement by means of standard air gaps * IEC 60055 Paper-insulated metal-sheathed cables for rat ...
