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.

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
