The Curtiss-Wright/Systran/Digital Technology DTI-2180 is a 6U VME module that implements MIL-STD-1553A and MIL-STD-1553B bus control, emulation, and monitoring functions. Built around a Texas Instruments Digital Signal Processor executing microcode, this Gold+ Series board delivers single-function monitoring or multi-function capabilities including error injection down to word and bit level. The module executes 1553 bus lists with minimal host overhead using extensive on-board instructions and dual-port RAM, making it suitable for hardware development, software development, and production test environments.
