IEC EN 61162-3 Marine Navigation and Radiocommunication Equipment and Systems - Digital Interfaces - Part 3: Serial Data Vehicle Network Testing

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 61162-3 testing. This part of IEC EN 61162 is based on the NMEA 2000 standard. The NMEA 2000 standard contains requirements for the minimum implementation of a serial data communications network for interconnecting marine electronic equipment on board ships. Equipment designed according to this standard shall be capable of sharing data, including commands and status, with other compatible equipment over a single signaling channel.

Data messages are transmitted as a series of data frames, each with strong error checking certified frame delivery and guaranteed delay times. Since the actual data content of a data frame is at best 50% of the bits transmitted, the primary purpose of this standard is to support relatively short data messages using query commands, which can be periodic, transmitted as needed or on demand.

Typical data include discrete parameters such as location latitude and longitude, GPS status values, routing commands to autopilots, finite parameter lists such as waypoints, and medium-sized data blocks such as electronic map database updates. This standard is not intended to support high-bandwidth applications such as radar, electronic maps, or other video data, or other intensive database or file transfer applications.

This standard defines all relevant layers of the International Standards Organization Open Systems Interconnection (ISO/OSI) model, from the application layer to the physical layer, required to implement the required IEC EN 61162-3 network functionality. This standard defines data formats, network protocol, and the minimum physical layer required for devices to interface. SOLAS implementations will use redundant designs (eg binary networks, redundant network interface circuits) to mitigate the impact of single point faults. The NMEA 2000 standard provides the basic tools and methods to support redundant equipment, buses, and messaging.
