Data Device Corp. (DDC) in Bohemia, N.Y., is announcing a PCI-104 card with as many as four dual-redundant MIL-STD-1553 channels, five user-programmable digital discrete I/Os, selectable external or internal time-tag clock, and an IRIG-B time synchronization input. The rugged BU-65577C is for convection- and conduction-cooled applications. The PCI-104 and PC/104 Plus form factors are common in flight data recorders, displays, and other avionics systems. The BU-65577C card uses DDC’s Extended Enhanced Mini-ACE (E2MA) architecture, which supports standard features for each 1553 channel such as 2 megabytes of RAM with parity per channel, 48-bit or 100-nanosecond time tag, and built-in self-test. Its intelligent hardware offload engine provides low PCI bus and host CPU utilization while storing 1553 monitor data in an IRIG-106 Chapter 10 format. The BU-65577C includes a high-level C application programming interface (API) library that supports architectural features, and driver support for Integrity, VxWorks, Linux, and Windows for MIL-STD-1553 functionality. The high-level library functions abstract all register accesses and memory allocation so that no specific hardware knowledge is required. For more information contact DDC online at www.ddc-web.com.
