The BU-65591U is a multi-I/O 1553 / ARINC 429 USB avionics device that provides new levels of performance and flexibility for systems interfacing to a MIL-STD-1553 or ARINC 429 data bus. There are up to two dual redundant MIL-STD-1553 channels operating in BC, RT, MT, and RT/MT modes. Four ARINC 429 Receive channels and two ARINC 429 Transmit channels operate in high/low speed with automatic slew rate adjustment.
The USB avionics device also contains digital discrete I/O and can be powered directly from the USB interface or by an external power source (optional). The combination of multiple I/Os on one device with a USB interface allows this to be used in laptops, desktops, tablets or any other computers with a USB port. The BU-65591U is ideal for lab applications that require an interface to a MIL-STD-1553 and / or ARINC 429 data bus while the BU-65590U provides the same functionality in a smaller, more rugged package that is ideal for flight line use and embedded systems.
The 1553 ARINC USB avionics device includes both 1553 and ARINC 429 Software Development Kits and graphical bus analysis and simulation tools. The Windows® based graphical bus analysis and simulation tools allow users to effortlessly simulate, monitor, and troubleshoot 1553 and ARINC 429 data buses simultaneously or independently without the need for time and cost prohibitive custom software coding.
Each 1553 channel uses DDC's Extended Enhanced Mini-ACE® (E²MA) architecture which is fully backwards API compatible with DDC's industry standard, field proven, Enhanced Mini-ACE. The USB avionics device includes the MIL-STD-1553 Enhanced Mini-ACE PLUS C Software Development Kit (SDK) and the ARINC-429 Multi-IO C SDK with drivers for Windows® 2000/XP. These SDKs allow you to quickly integrate DDC's USB 1553 and ARINC 429 I/O 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.
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 host CPU utilization.
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.
APPLICATIONS
The 1553 ARINC 429 USB avionics device is suited to a wide variety of applications. These include portable test equipment, diagnostic, demonstration, software development, system integration and lab debugging. The USB device enhances the work of developers, integrators, testers, field personnel and flight test crew through advanced ARINC 429 and 1553 capabilities that are accessible through a USB port.
