Scope
ARINC Specification 485, Part 2 specifies the ARINC 485-control protocol used by the LRUs described in ARINC Specification 628 Part 2. This document defines a multi-drop bus. The point-to-point configuration is also supported. The point-to-point bus is treated simply as a multi-drop bus with only one drop. There is one master LRU and one or more slave LRUs present on the bus. However; multiple buses may be connected in parallel, where each parallel bus operates independently from each other.

* 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.
