Bohemia, New York (May 2008) Data Device Corporation (DDC) introduces a new multi-protocol USB 2.0 Interface for MIL-STD-1553 and ARINC 429 data bus applications. The new BU-65591U is a lightweight USB 2.0 device that provides two dual redundant 1553 channels, four ARINC 429 receive channels, two ARINC 429 transmit channels, seven Digital Discrete I/Os, and an IRIG-B time synchronization input. In addition to the 1553/429 device, DDC offers 1553-only and 429-only versions. An extension to DDC’s rugged version that was released in 2006, the BU-65591U is ideal for lab applications that require an interface to MIL-STD-1553 and/or ARINC 429 data buses, while the BU-65590U provides the same functionality in a more rugged package that is ideal for flight line use and embedded systems.

“The high channel count and mix of 429 and 1553 in a USB device make it an ideal portable solution for avionics labs that use MIL-STD-1553 or ARINC 429 data buses”, said Mike Hegarty, DDC’s MIL-STD-1553 Marketing Manager.

The USB avionics device includes both 1553 and 429 C Software Development Kits (SDK) and drivers for Windows® 2000 and Windows® XP. These SDKs allow users to quickly integrate DDC’s 1553 and 429 I/O into a C source code application. 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. Graphical bus analysis and simulation tools for both MIL-STD-1553 and ARINC 429 are also available in addition to ARINC 615 data loading software. The graphical bus analysis and simulation tools allow users to effortlessly simulate, monitor, and troubleshoot 1553 and 429 data buses simultaneously or independently without the need for time and cost prohibitive custom software coding.
