Robust, high-speed MIL-STD-1553B communications using NI VeriStand and Alta interface hardware

The Bloomy Custom Device for Alta 1553 interface hardware is the only high-speed, robust MIL-STD-1553B solution available for NI VeriStand on the market today. Since its deployment over six years ago, multinational airframers have relied upon this custom device in their systems integration labs (SILs) for high-fidelity validation testing of line replaceable units (LRUs), avionics and systems.

MIL-STD-1553B is a low-speed avionics data protocol frequently used in aircraft for communication between different line-replaceable units (LRUs). Hardware-in-the-loop (HIL) simulators and systems integration labs (SILs) frequently simulate MIL-STD-1553B networks using devices such as Bloomy's 1553B C Series module. This article presents a high-level overview of MIL-STD-1553B communications and implementation.
