This SAE Aerospace Standard (AS) establishes guidelines for the use of IEEE-1394b as a
data bus network in military and aerospace vehicles. It encompasses the data bus cable
and its interface electronics for a system utilizing S400 over copper medium over extended
lengths. This document contains extensions/restrictions to “off-the-shelf” IEEE-1394
standards, and assumes that the reader already has a working knowledge of IEEE-1394.
This document does not identify specific environmental requirements (electromagnetic
compatibility, temperature, vibration, etc.); such requirements will be vehicle-specific and
even LRU-specific. However, the hardware requirements and examples contained herein
do address many of the environmental conditions that military and aerospace vehicles may
experience. One should reference the appropriate sections of MIL-STD-461E for their
particular LRU, and utilize handbooks such as MIL-HDBK-454A and MIL-HDBK-5400 for
guidance.
This document is referred to as a “slash sheet” and accompanies the SAE Sxxxx base
standard.
1.1 Purpose:
The purpose of this document is to define an approach to using IEEE-1394b over
extended distances in safety-critical/mission-critical applications for military and aerospace
vehicles.
This document is controlled and maintained by the SAE with technical support from
subsystem vendors.
1.2 Application:
The information herein may be used to assist the design, fabrication, and maintenance of
the subsystems that interface via the vehicle’s network.
1.3 Interpretation:
The following interpretations shall be placed upon these words, unless stated otherwise,
where they are used in this document.
May: An allowed action.
Shall: A mandatory requirement.
Should: A recommended action.
Will: A declaration of intent.strRefField
