The Astronics/EADS/Racal 405094 Enhanced Monitoring System (EMS) Module augments VXI mainframe monitoring capabilities with advanced data acquisition, analysis, and fault detection. Designed for integration with the Racal 1261B 13-Slot High-Performance VXI Mainframe, the EMS module operates on its own independent power rail and consumes no VXI slots, preserving system resource efficiency. It extends monitoring beyond basic SMS functionality through interactive interfaces over VXIbus and RS-232, enabling users to define custom limits, set maintenance intervals, and generate interrupts upon out-of-limit detection.
