Remote link unit functional design: An advanced remote terminal for MIL-STD-1553B

This report presents a functional design of the Remote Link Unit (RLU). The RLU is an intelligent remote terminal which is compatible with hierarchical distributed processing. It has interface modules capable of processing subsystem data on-the-fly and supporting a universal signal interface which can be configured under software control to input or output analog and digital signals of varied types. Electronic nameplates containing identification, interface requirements and signal processing programs are attached to avionics subsystems to support the RLU operational features. The RLU stand-alone processing capabilities provide fault tolerance and facilitate maintenance.
