Compatibility testing and integration of DAIS multiplex bus equipments

This paper describes the methods and tools to be used to integrate and verify compatibility of data bus equipment with the Digital Avionics Information System (DAIS) multiplex data bus. This includes definitions of DAIS multiplex bus compatibility, integration sequences, integration test software and test procedures. DAIS multiplex bus compatibility is defined for electrical, functional and system protocol considerations. The integration sequences described are stand alone, multiple unit and system level test. The integration test software described consists of a command generation program and the bus equipment diagnostic software. The test procedures describe how the test software is used at each stage of integration.
