Abstract:

Two defense contractors, Boeing and Semcor, have proposed standard data word formats for use with MIL-STD-1553 systems. These proposed formats differ in that the Boeing proposal is based on the historical usage of English units while the Semcor proposal is based on a conversion to metric units. At the request of the Tri-Service Multiplex Committee, the SAEA-2K Subcommittee for Multiplexing has formed a Data Word Standardization Task Group to revise Chapter 11, Data Word and Message Format Guidelines for publication in the Multiplex Applications Handbook. The Chapter 11 will contain both English and metric units to allow industry an orderly conversion to metric units while providing an unofficial standard for English units. The Task Group has revised the Boeing draft Chapter 11 with the following major changes an improved ICD format, modified data formating rules, a simplified procedure for developing nonstandard data words, and a detailed review of the data word formats. Chapter 11 will be submitted to the SAEAE-9 formerly A-2K Subcommittee at the fall 1982 meeting. Development of an all metric MIL-STD for data words within the next two years will be recommended.
