The Abaco Systems / Condor Engineering QVME-1553-1SA is a single-channel MIL-STD-1553 VMEbus interface board engineered for avionics and defense applications requiring high-performance military databus communication. It operates as a fully compliant MIL-STD-1553A and B Notice II interface, supporting Bus Controller (BC), Remote Terminal (RT), and Bus Monitor (BM) modes in multi-function or single-function configurations. The board delivers 1 Mbyte of RAM per channel with dual-redundant architecture and flexible coupling options—transformer or direct—to accommodate diverse system integration requirements.
