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
