IA3	MIL-STD 1553B

This course covers the 1553 military bus

Objectives The bus topology is explained. Bus frames are studied field per field. The architecture of a 1553 coupler is described. The course focuses on testing, covering also MIL-HDBK-1553A. The course details the software interface necessary to control the coupler. This course has been delivered several times to companies developing defense/avionics equipments. A more detailed course description is available on request at training@ac6-training.com

Prerequisites Basic knowledge of a processor or DSP.

INTRODUCTION History Utilization domain Objectives of this bus Protocol overview The 3 node types: BC, RT and BM Multiplex selection criteria PHYSICAL LAYER Introduction to differential transmission 1553B transmission medium Stubbing Connecting a terminal to a backbone, long stub Connection a terminal to a backbone, short stub Multi-stub couplers Terminal electrical characteristics LINK LAYER Terminal operation Manchester bi-phase coding scheme Word formats, SYNC pattern Word validation Command word detail Data word detail Status word detail, studying various sequences in order to explain Status flags Terminal architecture, word controller, message controller, frame controller MESSAGE FORMATS Remote Terminal operation, assigning an address The 10 message types Point-to-point messages Broadcast messages Studying various sequences explaining the way of transferring data from terminal to terminal Message timings, taking into account the round-trip delay Illegal commands vs invalid commands

MODE CODES Management messages Command format, subaddress specific usage Mode codes supporting data Dynamic bus control Synchronize commands, usage to implement a heardbeat Transmit Status word and Transmit Last command use cases Interface with self tests in both RT and subsystems Transmitter shutdown commands used in redundant systems SYSTEM ISSUES Using subaddress Double buffering Framing in the BC to support both periodic transfers and asynchronous transfers REDUNDANT DATA BUS REQUIREMENTS Electrical isolation Dual standby redundant data bus operation Superseding commands High reliability requirements TESTING Test plans described in 1553A handbook Using an analyzer to capture traffic Generating traffic to check how the system react in case of errors Data wrap around mechanism, remote loopback test
