标准范围

IEC 61162-2:2024包含海上电子仪器、导航和无线电通信设备之间通过适当接口互连时的数据通信要求。本文档旨在支持从单个说话者到一个或多个监听器的单向串行数据传输。这些数据是可打印的ASCII格式，可以包括经批准的句子指定的任何信息或根据专有句子规则编码的信息。典型的消息长度可以是11到最多79个字符，并且通常需要高达每20ms一次的重复率。本文件中的电气定义旨在适应比IEC 61162-1中规定的更高的数据速率。由于没有保证消息传递的规定，只有有限的错误检查能力，因此在所有安全应用中谨慎使用本文件是很重要的。

IEC 61162-2:2024 contains the requirements for data communication between maritime electronic instruments, navigation and radiocommunication equipment when interconnected via an appropriate interface. This document is intended to support one-way serial data transmission from a single talker to one or more listeners. This data is in printable ASCII form and can include any information as specified by approved sentences or information coded according to the rules for proprietary sentences. Typical messages can be from 11 to a maximum of 79 characters in length and generally require repetition rates up to once per 20 ms. The electrical definitions in this document are intended to accommodate higher data rates than are specified in IEC 61162-1. 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.
