The BU-65577/78Cx is a one to four channel MIL-STD-1553 card that provides new levels of performance and flexibility for PC/104-Plus (BU-65578C) or PCI-104 (BU-65577C) 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 Enhanced Mini-ACE software. Standard features include 2MB of RAM per channel, 48-bit message time tagging, IRIG-B time stamp input, IRIG-106 Chapter 10 format, transformer or direct 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 architecture 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. Storing data in the industry standard IRIG-106 Chapter 10 file format allows DDC’s cards to be used with digital flight data recorders.
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. The SDK allows users to develop source code to simulate, monitor, or troubleshoot 1553 data buses with support for the latest versions of operating systems including VxWorks 6, Linux 2.6, and Windows 2000/XP. This SDK allows you to quickly integrate DDC’s 1553 cards into your C source code applications. A common SDK exists across all operating systems allowing the programmer portability across different platforms. The easy-to-use high level functions abstract all low level hardware accesses and memory allocation such that specific hardware knowledge is not required.
The BU-65577/8Cx is designed for harsh environments and can be used in either conduction or convection cooled applications. Its rugged construction makes it ideal for use in flight data recorders, displays, ground vehicles, mission computers, and avionics labs.
