The Excalibur Systems M4K1553Px Avionics Communication Module is an intelligent, MIL-STD-1553 interface module for the multiprotocol Excalibur 4000 family of carrier boards. The M4K1553Px provides a complete solution for developing and testing 1553 interfaces and performing system simulation of the MIL-STD-1553 bus. The module handles all standard variations of the MIL-STD-1553 protocol. Each module of the M4K1553Px contains 64K bytes of dual-port RAM for Data Blocks, Control registers, and Look-up Tables. All Data Blocks and Control registers are memory mapped, and may be accessed in real-time. The M4K1553Px module can be programmed to operate in one of three modes of operation: Remote Terminal, Bus Controller/Concurrent-RT, and Bus Monitor. In addition, the module simultaneously performs as an Internal Concurrent Monitor in Remote Terminal and Bus Controller/Concurrent- RT modes.
