The BU-65568 is a COTS solution for interfacing between an embedded PC104 processor card and a MIL-STD-1553 bus. With one to four channels of DDC's field-proven Enhanced Mini-ACE, the BU-65568's advanced bus controller architecture provides considerable flexibility and autonomy in a number of areas. This includes methods to control message scheduling, along with the means to minimize host overhead for implementing data double buffering and bulk transfers, and inserting asynchronous messages. The BC architecture also supports various message retry and bus switching strategies, and provides flexibility for data logging and fault reporting.

The cards remote terminal architecture provides flexibility in meeting all common MIL-STD-1553 protocols. The choices of RT buffering and interrupt options provide robust support for synchronous and asynchronous messaging, while ensuring data sample consistency and supporting bulk data transfers.

The card includes a true message monitor mode and a combined RT/Monitor mode for highly flexible message filtering and robust interrupt architecture that simplifies host software.

The BU-65568 includes two addressing modes, to provide consistancy of compatibility with both Intel and Motorola pressure platforms. The BU-65568 comes with BU-69090 series software, a library supporting all modes of operation, DOS and VxWorks device drivers including source code, and an offline development environment. The BU-65568 also includes an 8-bit bi-directional I/O port.
