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.

Advantages

  • 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

 

Functions

  • 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

Testing under time pressure - Versatile test benches for avionic systems

In the future, test benches will be made up from subsystems that are manufactured by specialized suppliers. It is very important to make sure that the test benches are available during the complete development cycle. This also includes after the commissioning of the aircraft type. The solution therefore is to use configurable computer systems as the basic architecture.
