MIL-STD-1553B 


MIL-STD-1553B is a military standard that defines a robust, time-division multiplexed (TDM) data bus for communication between avionics systems. Developed in the 1970s, it is widely used in military and aerospace applications due to its reliability, deterministic performance, and fault-tolerant design. The standard specifies electrical characteristics, protocol, and message formats, enabling real-time communication between a bus controller (BC), remote terminals (RTs), and up to 31 devices on a single bus. MIL-STD-1553B supports high-integrity data transmission, making it ideal for mission-critical systems in aircraft, spacecraft, and ground vehicles.

  • Up to eight dual-redundant MIL-STD-1553/1760 channels 
  • Supports MIL-STD-1553B, H009 or 16PP194 protocols 
  • Single-function and tester versions 
  • Single function boards can operate as BC, Multi-RT or Monitor 
  • Tester versions provide simultaneous emulation of BC, Multi-RT (up to 32) and Monitor, with BC or RT error injection 

 ARINC 429

ARINC 429 is a standardized data transfer protocol widely used in commercial and military aviation for communication between avionics systems. It defines a point-to-point, one-way communication system where a single transmitter can send data to up to 20 receivers over a twisted pair of wires. The protocol uses a 32-bit word format, with data transmitted at either 12.5 or 100/kilobits per second. ARINC 429 is known for its simplicity, reliability, and ease of implementation, making it a cornerstone in aircraft systems for transmitting critical data such as flight controls, navigation, and engine parameters.
