MIL-STD-1553 is a military standard that defines mechanical, electrical, and operating characteristics of a serial data communication bus for integration of aircraft subsystems. It is the most popular serial databus in military avionics today, and since it was first published in 1973 it has been adopted by all branched of the US military and NATO. The MIL-STD-1553 standard is now commonly used for both military and civilian applications in avionics, aircraft, and spacecraft data handling. A 1553 system typically uses a dual redundant, balanced-line, physical layer with a differential network interface with time division multiplexing, half-duplex, command/response data communication protocol with up to 31 remote terminal devices. United Electronic Industries offers a high performance, two channel MIL-STD-1553 interface for UEI’s popular I/O “Cubes”. The board provides two independent, dual redundant bus interfaces for 1553 communication. Each 1553 communication port can be individually configured as a bus controller, remote terminal, or…
