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.
