DDC is uniquely qualified to support a wide range of application requirements and technologies based upon our decades of experience in analog and digital microelectronics, magnetics, power supplies, radiation mitigation technology and top quality certifications for AS9100 Rev C, ISO 9001:2008, EN9100, JIS Q9100 and through the DLA MIL-PRF-38534.
DDC's BU-65580/81CX Series of PC/104 cards provide a complete COTS solution for interfacing between an embedded PC/104 bus and one to four Enhanced Bit Rate - 1553 Channel(s) with supporting CANBus interface(s), while also providing an optional MIL-STD-1553 dual redundant interface. Enhanced Bit Rate - 1553 (EBR-1553) is a 10Mbps data bus protocol based on the familiar MIL-STD-1553. The cards two addressing modes serve to provide compatibility with both Intel and Motorola processor platforms.
The BU-65580/81CX includes one to four channel(s) of EBR-1553. The cards advanced Bus Controller (BC) architecture is software compatible with DDC's ACE-Core Software for VxWorks or DOS. This architecture provides a high degree of flexibility and autonomy. This includes methods to control message scheduling, the means to minimize host overhead for asynchronous message insertion, the ability to facilitate bulk data transfers and double buffering, and support for various message retry strategies. The BC architecture also provides flexibility for data logging and fault reporting.
The card's Remote Terminal (RT) architecture provides a great deal of flexibility. The choice of RT data buffering and interrupt options provides robust support for synchronous and asynchronous messaging, while ensuring data sample consistency and supporting bulk data transfers.
The BU-65580/81CX Series cards also include one to four supporting CANBus interface(s) for MMSI EBR-1553 serial RT addressing and a 12-bit bi-directional discrete I/O port. The BU-65581CX adds an optional MIL-STD-1553 dual redundant interface.
