ABI-cPCI MIL-STD-1553 Interface Features 1 or 2 dual redundant 1553 channels featuring 100% concurrent and independent operation as a: • Bus Controller • 31 Remote Terminals • Dual Function Bus Monitor Bus Controller • Programmable frame lists • BC-RT, RT-BC, RT-RT • Mode codes, broadcasts, and time delays ABI-cPCI interface provides a flexible, full function, dual redundant MIL-STD-1553 interface to the cPCI backplane. This Advanced Bus Interface (ABI) architecture provides concurrent and independent operation of a Bus Controller (BC), 31 Remote Terminals (RT), RT Functionality and dual function Bus Monitoring (BM). The ABI-cPCI interface equips the PCI bus system • RT level protocol selection with a complete 1553 interface. This includes 1553A/1553B selections, pointer-driven • RT definition tables transmit and receive buffers and extensive programmable event interrupts. • Programmable response time BC simulation structures consist of linked lists of 1553 command messages: BC-to-RT, RT- Bus Monitor to-BC, RT-to-RT, mode code, broadcast and time delay block transmissions. We define RT simulation as a simple series of pointers to RT definition tables. The RT definition tables in • Map monitoring turn point to control data buffers.
