This document defines a recommended practice for implementing a bi-directional@ serial communication link among modules containing microcomputers. This document defines those parameters of the serial link which 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 Recommended practice. These and other details of communication link implementation and use should be specified in the separate application documents referenced PURPOSE: The purpose of this Recommended practice is to define a general-purpose serial data communication link that may be utilized in heavy-duty vehicle applications. It is intended to serve as a guide toward standard practice to promote serial communication compatibility among microcomputer-based modules. The primary use of the general-purpose communications link is expected to be the sharing of data among stand-alone modules to cost-effectively enhance their operation. Communication links used to implement functions that require a dedicated communication link between specific modules may deviate from this document.
