The AT-USB-MPAC family of products provides the highest level of performance and flexibility on various hardware interface architectures and custom platforms. Integrating MIL-STD-1553B, ARINC429 and Digital I/O channels, all in a single unit, it offers the ideal platform for test & evaluation of avionics systems and sub-systems. On board six discrete inputs and six discrete outputs, IRIG-B Time code Input/Output is also available. An onboard IRIG-B time code decoder and generator allow users to accurately synchronize single or multiple USB MPAC modules to a common time source.


The AT-USB-MPAC software includes Drivers and APIs. The module comes with a powerful set of library functions to access the entire MIL-STD-1553B and ARINC429 functionality. Source code is provided for samples, and detailed documentation. The drivers are designed in a modular fashion consisting of component functions & application functions. The users test program can be developed with few calls to the driver, by using the set of Application functions provided. Driver and high-level API libraries for Windows 7, Linux are available.
