Scope

This document 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. Purpose: The purpose of this document Is to define a general-purpose serial data communication link that may be utilized 1n heavy duty vehicle applications. It 1s 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.
