Serial Data Communications Between Microcomputer Systems in Heavy-Duty Vehicle Applications
J1708_201012
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:
Added MID 125 Assignment from SAE J2497 and made changes to Applicable Documents and other minor document fixes to bring SAE J1708 in line with current SAE Standards format.
