DDC BU-67103U200L-JL0 USB Avionics Device with MIL-STD-1553 and ARINC 429 Interfaces

The DDC BU-67103U200L-JL0 is a USB-based avionics test device that delivers dual-protocol support for MIL-STD-1553 and ARINC 429 bus communication. Purpose-built for laboratory testing, simulation, field maintenance, and flight-line diagnostics, this portable instrument connects via USB 2.0 to desktop, laptop, or tablet computers and operates from either USB power or an included external power source.

## Technical Specifications

**MIL-STD-1553 Interface**
• 1 or 2 dual-redundant channels

• Concurrent Bus Monitor (MT) operation per channel
• 1 MB RAM with parity per channel
• Includes BU-69092S AceXtreme® C SDK with source code samples

**ARINC 429 Interface**
• 4 receive channels
• 2 transmit channels
• Full data line rate support: low speed, high speed, and ARINC 575 speeds
• Automatic slew rate adjustment
• Includes DD-42992S ARINC 429 C SDK with source code samples

**Digital I/O & Timing**
• 8 user-programmable digital discrete I/Os
• IRIG-B time code input
• 1 Pulse-per-Second (PPS) output
• 48-bit / 100 ns time stamp resolution

**Environmental & Physical**
• Operating temperature: 0°C to +55°C (extended temperature hardware available)
• Compact, portable form factor; durable construction

## Key Features

Dual-protocol capability eliminates need for separate test instruments. Concurrent Bus Monitor operation enables passive traffic observation while actively driving MIL-STD-1553 bus states. Programmable discrete I/Os and precise time stamping support complex system integration and debugging workflows. Multiple ARINC 429 channels handle multi-source data bus architectures without external multiplexing.

## Typical Applications

• Box-level and system integration testing
• Real-time avionics bus simulation and analysis
• Flight-line test and field diagnostics
• Software development and debugging
• Flight instrumentation applications

## Compatibility & Integration

Supports Windows 10/8/7 and Windows Vista (32/64-bit). Optional software includes MIL-STD-1553 BusTrACEr Analyzer Simulator, ARINC 429 Data Bus Analyzer (DBA), ARINC 615 Data Loader, LabVIEW multi-I/O support package, and dataSIMS Real-Time Avionics Bus Analysis & Simulation Tool.
