This standard defines the recommended multiplexer format for single-channel data recording on small-format (1/2 in.) media. This format is recognized as the Asynchronous Recorder Multiplexer Output Re-constructor (ARMOR). This format is software-reconfigurable for each data acquisition or reproduction. The ARMOR format configuration information is stored in a data structure called a setup that contains all the information necessary to define a particular record or play configuration. This annex describes the format and content of the ARMOR setup. This standard is retired but maintained for historical purposes.
