DDCs BU-65578Cx is a one to four channel MIL-STD-1553 card that provides new levels of performance and flexibility for PC/104-Plus or PCI-104 systems that interface to a MIL-STD-1553 data bus. The card uses DDC s Extended Enhanced Mini-ACE (E²MA) architecture, which is API compatible with the industry standard Enhanced Mini-ACE software. Features include 2MB of RAM per channel, 48-bit message time tagging, IRIG-B time stamp input, IRIG-106 Chapter 10 format, transformer coupling, triggers, extensive BC & RT frame structures, error detection, RT Status Bit and Mode Code responses, and advanced Bus Controller functionality. Each channel is individually configurable as a Bus Controller (BC), Remote Terminal (RT), Bus Monitor (MT) or combined RT / Monitor. The advanced BC architecture provides a high degree of flexibility and autonomy by improving message schedule control, minimizing host overhead for asynchronous message insertion, facilitating bulk data transfers, double buffering, message retry, bus switching strategies, data logging, and fault reporting. The RT architecture provides flexibility in meeting all MIL-STD-1553B protocols. The card has an intelligent hardware offload DMA engine that dramatically reduces PCI bus and host CPU utilization while storing 1553 monitor data in a convenient and portable IRIG-106 Chapter 10 file format. The card includes the MIL-STD-1553 Enhanced Mini-ACE (EMACE) Plus C Software Development Kit (SDK) and drivers to support all modes of operation for Linux, VxWorks and Windows 2000/XP, including source code samples and detailed documentation.
