The VME2303 is an intelligent interface card for two channel, dual redundant MIL-STD-1553 applications. It gives full MIL-STD-1553 test, simulation and bus analysis capability on the VME bus, providing 1553A, 1553B, McAir and STANAG 3838 variants in a single card. Each channels supports concurrent Bus Controller (BC) and up to 31 Remote Terminals (RT) with Bus Monitor (BM). An additional stand-alone Chronological Bus Monitor (CBM) facility is also provided, with comprehensive multi-level triggering capability. Full error injection capability is provided in BC and RT modes, with full error detection in BC, RT, BM and CBM modes. The unit provides two variable amplitude dual redundant 1553 interfaces.
8 Mbytes of dual ported RAM are provided on each channel. The board is supplied with C drivers in source code and Windows menu driven software as standard.
