DDC Announces New 1553/429 Avionics USB 2.0 Interface

Bohemia, New York (June 1, 2006) Data Device Corporation (DDC) introduces a new multi-protocol USB 2.0 Interface for MIL-STD 1553 and ARINC-429 data bus applications. The BU-65590U is a small, lightweight, rugged USB 2.0 Interface that provides two dual-redundant 1553 channels, four ARINC 429 receive channels, two ARINC 429 transmit channels, Eight User-programmable Digital Discrete I/Os and an IRIG-B time synchronization input. Powered directly from the computer’s USB port, the BU-65590U is a portable solution suitable for use with virtually any laptop, desktop, or tablet computer.

“The rugged construction and small size of the USB Interface make it an ideal solution for avionics labs, field service, flight-line test equipment, and flight instrumentation applications using MIL-STD 1553 or ARINC 429 data buses,” said Todd Decker, DDC’s MIL-STD-1553 Marketing Manager.

DDC’s new Extended Enhanced Mini-ACE (E2MA) Architecture is used for the 1553 interface. Based on DDC’s field-proven, industry standard Enhanced Mini-ACE Architecture, the new E²MA architecture builds on previous generations of DDC products, defining the future of MIL-STD 1553 and ARINC 429 while maintaining full legacy compatibility. The architecture supports new standard features for each 1553 channel such as 1 MB RAM with parity, 48-bit / 1 micro-second time tag synchronized to an IRIG-B input, and built-in self test. Each 1553 channel can emulate a Bus Controller, Remote Terminal, or Bus Monitor. The device also includes a combined RT/Monitor mode for surveillance of all 1553 communications on the bus, including the 1553 channel’s own RT address.

The BU-65590U includes High Level C API (Application Programming Interface) Library Software that supports all advanced architectural features, and driver support for Windows 2000 and Windows XP for MIL-STD-1553 and ARINC 429 functionality. Sophisticated yet user-friendly library functions abstract all register accesses and memory allocation; no specific hardware knowledge is necessary. The USB Interface is also compatible with DDC’s dataSIMS advanced monitoring software.

In addition to the combined 1553/429 device, DDC offers 1553-only and 429-only versions. Prototypes with MIL-STD-1553 capability are available now and devices that include ARINC-429 interface capability will be available later this year.
