IEC 61162-1:2024

Maritime navigation and radiocommunication equipment and systems - Digital interfaces - Part 1: Single talker and multiple listeners

IEC 61162-1:2024 contains the requirements for data communication between maritime electronic instruments, navigation and radiocommunication equipment when interconnected via an appropriate system. This document 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, etc. 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. 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. For applications where a faster transmission rate is necessary, IEC 61162-2 applies. For applications to shore based equipment of the automatic identification system (AIS) the IEC 62320 series applies.

Matériels et systèmes de navigation et de radiocommunication maritimes - Interfaces numériques - Partie 1: Émetteur unique et récepteurs multiples

L'IEC 61162-1:2024 contient les exigences pour la communication des données entre les instruments maritimes électroniques, les matériels de navigation et de radiocommunications lorsqu'ils sont interconnectés par l'intermédiaire d'un système approprié. Le présent document est destiné à prendre en charge l'émission unidirectionnelle de données série entre un seul émetteur et un ou plusieurs récepteurs. Ces données sont au format ASCII imprimable et peuvent inclure des informations telles que la position, la vitesse, la profondeur, l'allocation de fréquences, etc. Les messages types peuvent être de longueur comprise entre environ 11 et 79 caractères au maximum et nécessitent généralement une émission pas plus rapide qu'un seul message par seconde. Les définitions électriques du présent document ne sont pas destinées à gérer les applications à large bande passante comme les radars ou l'imagerie vidéo, ou encore les bases de données intensives et les applications de transfert de fichiers. En l'absence de disposition assurant l'émission des messages et compte tenu de la capacité limitée de vérification des erreurs, il est important d'utiliser le présent document avec précaution dans toutes les applications de sécurité. Pour les applications dans lesquelles un débit d'émission plus rapide est nécessaire, l'IEC 61162-2 s'applique.
