The BU-65590F/M is a multi-protocol PMC card providing new levels of performance and flexibility for systems interfacing to a MIL-STD-1553 or ARINC 429 data bus. There are up to four dual redundant MIL-STD-1553 channels operating in BC, RT, MT, or RT/MT modes. Sixteen ARINC 429 receive channels and six ARINC 429 transmit channels operate in high/low speed with automatic slew rate adjustment. The card also contains up to six digital discrete I/Os, an IRIG-B time synchronization input, two RS-422/485 Serial I/O channels, and up to two RS-232 Serial I/O Channels. The combination of multiple I/O on one card saves valuable PMC sites on host computers.
Each 1553 channel uses DDCs Extended Enhanced Mini-ACE® (E2MA) architecture which is fully backwards API compatible with DDCs industry standard, field proven, Enhanced Mini-ACE. Each 1553 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 DDCs cards to be used with digital flight data recorders.
Each ARINC 429 channel supports maximum data throughput on all channels while providing message scheduling, label filtering, and full error detection. Received data can be stored in either FIFO buffers or system address label mailboxes. Each channel features independent selection of data rate and parity, and automatic transmit channel slew rate adjustment. Transmit data can be sent in FIFO mode or scheduled rate mode on each transmit channel.
The card includes the MIL-STD-1553 Enhanced Mini-ACE (EMACE) Plus C Software Development Kit (SDK) and the ARINC 429 Multi-I/O C SDK with drivers for Linux, VxWorks and Windows 2000/XP, including source code samples and detailed documentation. These SDKs allow users to develop source code to simulate, monitor, or troubleshoot 1553 or ARINC 429 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 DDCs 1553 and/or 429 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.
APPLICATIONS
The BU-65590F/M is designed for harsh environments and can be used in either conduction or air-cooled applications. The card is available with front panel I/O or rear I/O. The cards rugged construction and ability to operate from -40°C to +85°C at the thermal rail make it ideal for use in flight data recorders, display applications, embedded black boxes, mission computers, and avionics labs.
