IEC 61162-2:20 24 CMV包含官方标准及其注释版本。注释版本为您提供了一种快速简单的方法来比较IEC 61162-2:20 24 2.0版和之前的IEC 61162-1:19 98 1.0版之间的所有更改。此外，还提供了IEC TC 80专家的意见，以解释最相关变更的原因，或澄清内容的任何部分。 IEC 61162-2:20 24包含海事电子仪器、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通话者到一个或多个收听者的单向串行数据传输。该数据是可打印的ASCII形式，并且可以包括由批准的句子指定的任何信息或根据专有句子的规则编码的信息。典型的消息的长度可以从11个字符到最大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。由于没有提供有保证的消息传递，并且只有有限的错误检查能力，因此在所有安全应用程序中谨慎使用本文档非常重要。

IEC 61162-2:2024 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 61162-2:2024 edition 2.0 and the previous IEC 61162-1:1998 edition 1.0. Furthermore, comments from IEC TC 80 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content.

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.
