标准摘要
[中文适用范围]: 本 SAE 推荐规范中描述的通信驱动程序位于 PC 与每个供应商开发的各个应用程序之间的 SAE J1708 硬件之间。从应用程序的角度来看,SAE J1708 硬件是完全透明的。这意味着诊断程序可以在使用任何 SAE J1708 适配器硬件的任何 PC 上运行。诊断(应用程序)程序看不出从一个硬件基础到另一个硬件基础有任何区别。所有特定于硬件的任务都由本文件处理。这允许软件程序的完全可移植性。它还保证了从一个硬件平台到另一个硬件平台的完全功能性。所 presented 的标准适用于使用 MS-DOS 操作系统的计算机系统。未来可能会为其他操作系统定义具有相同功能的设计标准。 [外文原描述]: This SAE Recommended Practice defines a recommended practice for implementing a bidirectional, serial communication link among modules containing microcomputers. This document defines those parameters of the serial link that relate primarily to hardware and basic software compatibility such as interface requirements, system protocol, and message format. The actual data to be transmitted by particular modules, which is an important aspect of communications compatibility, is not specified in this document. These and other details of communication link implementation and use should be specified in the separate application documents referenced in Section 2 .Cross Reference: EIARS-485,J1455_201101,J1455_201703,J1587,J1587_201301,J1922,J1922_201108,J2497,J2497_201207
