Serial Data Communications Between Microcomputer Systems in Heavy-Duty Vehicle Applications
J1708_200810
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.
Rationale:
Change made to Section 6.3.3.2 to direct device manufacturers using MIDs less than 128 that interact with PLC applications to consult latest SAE J2497.
