The Aeroflex Circuit Technology Model ARX2412 Manchester Converter is a self contained, 48pin,
triple-in-line hybrid package designed to perform: encode, decode, logic and control functions in a
MIL-STD-1553, A and B multiplex data system. It Provides the necessary interface between transceivers and
a three state parallel 16 bit bus of the protocol logic section of a subsystem remote terminal or controller.
