Description / Abstract:
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.
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.
Application:
The information herein may be used to assist the design, fabrication,
and maintenance of the
subsystems that interface via the vehicle's network.
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.
