Scope
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.

Reference
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
