The BCT-302 1553 Test Bus CardThe desire to control an LRU and/or MIL-STD 1760 store via an independent 1553 stream on current weapon platforms created the need for the development of the BCT-302 1553 Test Bus Card. This solution solves the issues of integration without the need to perform an aircraft OFP change. The BCT- 302 is a customized MIL-STD-1553 card for use in Teletronics Technology Corporation, (TTC), Airborne Instrumentation Multiplexer (AIM) and High-Speed Avionics Data Acquisition Unit (HSAVDAU) products. The BCT-302 card consists of two redundant MIL-STD-1553 ports. Each port is independently configurable by the AIM/HSAVDAU host processor to function as a Bus Controller (BC), Remote Terminal (RT) or Bus Monitor (BM). The system is capable of cherry picking parameters from any 1553 bus and retransmitting assembled messages to a weapon and/or an LRU in a 1553 format. This paper describes the design requirements of the BCT card and how those requirements were met during an AIM-9X launch on an F-22.
