The AT-PMC-MPAC family of products provides the highest level of performance and flexibility on various hardware interface architectures and custom platforms. Integrating MIL-STD-1553B, ARINC717 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 seven discrete inputs and seven discrete outputs is also available. To provide I/O and processing expansion capabilities, IO are available on either rear user IO connectors or Front Panel VHDCI Connectors. The AT-PMC-1553 + ARINC717 board is available in Conduction-cooled version.

The AT-PMC-MPAC is the latest generation of high performance and flexibility for MIL-STD-1553B functionality. The AT-PMC-MPAC offers full-function test, simulation, monitoring, and data bus analyzer functions for MIL-STD-1553B applications. These high-density high-performance modules are suitable for applications ranging from test equipment to rugged deployable systems. The module comes integrated with powerful software that reduces application development time. All data bus functionality is supported by our advanced API (Application Programming Interface).

The Total-ACE is a complete and compact solution to MIL-STD-1553 applications. It integrates dual transceivers, dual transformers, protocol engine and 64K words of internal RAM combined into a single BGA package. The device is powered by +3.3 volts.

The advanced BC architecture provides a high degree of flexibility and autonomy by improving message scheduling control, minimizing host overhead for asynchronous message insertion, facilitating bulk data transfers and double buffering, message retry and bus switching strategies, and data logging and fault reporting. The RT architecture provides flexibility in meeting all common MIL-STD-1553 protocols. RT data buffering and interrupt options offer support for synchronous and asynchronous messaging, ensure data sample consistency, and support bulk data transfers.

Transformer and Direct Coupling
The module can be configured to work either in the transformer- coupled mode or in the direct-coupled mode. Jumpers are provided on the modules to select the mode. It is configured to work in Transformer coupled mode by default.
