Title:Serial Data Communications Between Microcomputer Systems in Heavy-Duty Vehicle Applications
Issuing Committee:Truck And Bus Low Speed Communication Network Committee
Scope:This SAE Recommended Practice defines a recommended practice for implementing a bidirectional, serialcommunication link among modules containing microcomputers. This document defines those parameters of the seriallink 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 ofcommunications compatibility, is not specified in this document. These and other details of communication linkimplementation and use should be specified in the separate application documents referenced in Section 2.
