Abstract:

In recent years,owing to its advantages of simple construction,good reliability,high transfer rate,mature technology,and good extendibility,MIL-STD-1553B bus has been widely adopted in aerospace observe and control network.BU-61580 interface protocol chip,manufactured by DDC Company of America for realizing the converting from microprocessor to 1553B bus signal,has the characteristics of BC/RT/M integrative design,single power supply,and electromagnetism compatibility that meet the requirements of Army standard.The 1553B bus board based on BU-61580 design is introduced in this article,which can be widely used in aviation and communication for strong ability of extending and functions.

Key words: 1553B bus;configuration register;semiduplex mode;bus controller;remote terminal
