10 Megabit/sec Network Configuration Digital Time Division Command/Response Multiplex Data Bus
2013-04-29
HISTORICAL
AS5652
This SAE Aerospace Standard (AS) contains requirements for a digital time division command/response multiplex data bus, for use in systems integration that is functionally similar to MIL-STD-1553B with Notice 2 but with a star topology and some deleted functionality. Even with the use of this document, differences may exist between multiplex data buses in different system applications due to particular application requirements and the options allowed in this document. The system designer must recognize this fact and design the multiplex bus controller (BC) hardware and software to accommodate such differences. These designer selected options must exist to allow the necessary flexibility in the design of specific multiplex systems in order to provide for the control mechanism, architectural redundancy, degradation concept, and traffic patterns peculiar to the specific application requirements.

HIGH SPEED RING BUS (HSRB) STANDARD
1988-08-29
HISTORICAL
AS4075
A fault tolerant, real time high speed data communication standard is defined based on a ring topology and the use of a Token passing access method with distributed control. The requirements for the HSRB standard have been driven predominantly, but not exclusively, by military applications. Particular attention has been given to the need for low message latency, deterministic message priority and comprehensive reconfiguration capabilities. This document contains a definition of the semantics and protocol including delimiters, tokens, message priority, addressing, error detection and recovery schemes; and is written to be independent of bit rate and media. Parameters related to particular media and bit rates are defined in separate documents, the AS4075 slash sheets.

IEEE-1394b Interface Requirements for Military and Aerospace Vehicle Applications
2016-04-04
CURRENT
AS5643B
IEEE-1394b, Interface Requirements for Military and Aerospace Vehicle Applications, establishes the requirements for the use of IEEE Std 1394™-2008 as a data bus network in military and aerospace vehicles. The portion of IEEE Std 1394™-2008 standard used by AS5643 is referred to as IEEE-1394 Beta (formerly referred to as IEEE-1394b.) It defines the concept of operations and information flow on the network. As discussed in 1.4, this specification contains extensions/restrictions to “off-the-shelf” IEEE-1394 standards and assumes the reader already has a working knowledge of IEEE-1394. This document is referred to as the “base” specification, containing the generic requirements that specify data bus characteristics, data formats, and node operation.

This document is referred to as the “base” specification, containing the generic requirements that specify data bus characteristics, data formats and node operation. It is important to note that this specification is not stand-alone - several requirements provide only example implementations and delegate the actual implementation to be specified by the network architect/integrator for a particular vehicle application. This information is typically contained in a “network profile” slash sheet that is subservient to this base specification.

OPTICAL IMPLEMENTATION RELATING TO THE HIGH SPEED RING BUS (HSRB) STANDARD
1995-01-01
HISTORICAL
AS4075/1
This SAE Aerospace Standard (AS) has been prepared by the Ring Implementation Task Group of the SAE AS-2 Committee. It is intended as a companion document to the SAE AS4075 High Speed Ring Bus Standard. While the Standard is intended to provide as complete a description as possible of an HSRB implementation, certain parameters are system-dependent and evolutionary. This document contains those parameters. The text through Table 1 is intended to provide definitions and descriptions applicable to all applications. Table 2 contains specific parameter values for one or more implementations. This table will change as new systems are implemented or new HSRB speed options are defined.

S400 Copper Media Interface Characteristics Over Extended Distances
2004-12-30
HISTORICAL
AS5643/1
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.
