Compact and Flexible Interface
for ARINC 429 Bus Systems

VN0601 - Interface for ARINC 429

The VN0601 is a compact and powerful interface for ARINC 429 bus systems. The interface conveniently utilizes a PC connection via USB 2.0, it does not require an external power supply, and it has analog/digital interfaces for acquiring other measurement parameters. The VN0601 gives developers of networked electronic units in aircrafts (Line Replaceable Units or LRUs) a high-performance interface solution for testing and bus analysis.


  • 4 ARINC 429 TX and 4 ARINC 429 RX channels
  • Supports High-Speed and Low-Speed communication
  • Host interface via USB 2.0
  • Does not require any external power supply
  • Precise time stamps
  • Synchronization with multiple devices and other bus systems (e.g. CAN, Ethernet, AFDX®)
  • Optimal performance with the CANoe.A429 tool for monitoring, debugging and testing avionic systems
  • Open interface for third-party tools with the XL Driver Library
  • High flexibility based on reloadable FPGA hardware architecture
  • Very rugged housing
  • Analog/digital IO
  • Electrical isolation of all connections



  • Variable channel-specific settings
    • Bit rates:
      > RX: 10 - 120 kBit/s (mode for automatic bit rate detection available)
      > TX: 10.5 - 16 kBit/s (Low-Speed), 90 - 110 kBit/s (High-Speed)
    • Parity check and parity generation in hardware (odd, even, none)
    • Minimum interval (gap) between ARINC words

  • Message-specific settings for parity and gap
  • Detailed error signaling (e.g. bit rate, duty cycle, parity, TX gap)
  • Evaluation of TX errors by feedback channel
  • Separate hardware scheduler for each TX channel for periodic transmission of ARINC words
  • Statistical function for bus analysis
  • Quick analysis and generation, even in complex communication scenarios with CANoe.A429
