Navigations- und Funkkommunikationsgeräte und -systeme für die Seeschifffahrt - Digitale Schnittstellen - Teil 1: Ein Datensender und mehrere Datenempfänger (IEC 61162-1:2024); Deutsche Fassung EN IEC 61162-1:2024
Overview
This part of IEC 61162 deals with the requirements for data communication between electronic instruments, in particular maritime navigation and radiocommunication equipment, and is intended to support one-way serial data transmission from a single talker to one or more listeners. These data are in printable ASCII form and can include information such as position, speed, depth, frequency allocation, etcetera. Typical messages can be from about 11 to a maximum of 79 characters in length and generally require transmission no more rapidly than one message per second. This part of IEC 61162 contains the requirements for data communication between maritime electronic instruments, navigation and radiocommunication equipment when interconnected via an appropriate system. The electrical definitions in this document are not intended to accommodate high-bandwidth applications such as radar or video imagery, or intensive database or file transfer applications. Since there is no provision for guaranteed delivery of messages and only limited error checking capability, it is important this document is used with caution in all safety applications. The standard differs from DIN EN 61162-1:2017-05 as follows: a) alternative hardware is listed in 5.1, which can now be as specified in this document or as specified in IEC 61162-2. b) the data transfer rate specified in Clause 6 is now configurable - the default setting remains 4 800 (bits/s), but higher rates can also be specified; c) new identifications have been added to Table 4; d) the new sets AGL, EPM, GDC, NLS, SEL, SLM, SMV, and VBC have been added; e) revisions have been made to ABK, ABM, ACN, ALC, ALF, ARC, BBM, DDC, DTM, EPV, FIR, GBS, GFA, GLL, GNS, GRS, GSA, GST, GSV, HRM, NRX, POS, RLM, ROR, RSA, TLB, TTD, VSD, and XDR; f) the original Annex A, Glossary, has been deleted as it is of historical interest. Typical examples of applications include communication between maritime navigation and radio communication systems, the transmission of GNSS data (such as GPS), and the integration of electronic instruments on board ships that are connected to each other via serial interfaces. Examples of data transmissions include information such as position, speed, and course.
