标准摘要
[中文适用范围]： 本部分IEC 61162规定了通过适当接口互连的航海电子仪器、导航和无线电通信设备之间数据通信的要求。 本文件旨在支持从单一发送器到一个或多个接收器的单向串行数据传输。数据以可打印的ASCII形式存在，可以包括根据批准的句子或根据专有句子规则编码的信息。典型消息长度为11至最多79个字符，通常需要重复率高达每20毫秒一次。 本文档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。由于没有提供消息的保证交付，并且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非常重要。 [外文原描述]： 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.
