Product Description

CANFDDTU-400ER Four-Channel CAN FD Data Logger (Automotive Black Box)
The CANFDDTU-400ER is a professional-grade, industrial-strength automotive CAN FD data recorder (black box). Designed for long-term, reliable offline recording of CAN(FD)-bus data, it is an essential tool for fault diagnosis, performance analysis, and enhancing network reliability in automotive electronics, rail transit, and industrial automation applications. This 4-channel model focuses on high-capacity local storage and flexible recording capabilities.
Key Features & Advantages
  • Multi-Channel CAN FD Recording

    Features 4 independent, user-configurable CAN FD channels for simultaneous monitoring and data acquisition from multiple bus lines or vehicle functional domains.

  • High-Capacity Storage & Flexible Recording

    Supports local data logging onto a high-speed SD card. The configuration software allows setup of various intelligent recording modes: long-duration, conditional, pre-trigger, and timed recording.

  • Powerful Data Analysis Compatibility

    Recorded data can be saved and converted into nine standard formats (BLF, ASC, CSV, etc.) and is fully compatible with advanced automotive bus analysis software suites ZXDoc/ZCANPRO for in-depth offline analysis, DBC parsing, and diagnostics.

  • Physical Trigger for Fault Marking

    Includes a dedicated Trigger button to mark specific bus message data in real-time during testing, enabling rapid identification and localization of intermittent faults within the recorded files.

  • Robust Industrial Design

    Built with a durable metal housing for harsh environments. Features channel isolation for protection and is designed for reliable operation across a wide temperature range with a wide DC input voltage.

  • Strictly Tested & Certified

    The series undergoes rigorous anti-vibration and harsh environment testing, ensuring stable performance in demanding applications like vehicles, ships, and industrial machinery. The series is certified as a High-Tech Product.

Note: This model (CANFDDTU-400ER) is designed for local data logging and does not include built-in 4G cellular or WiFi connectivity for real-time cloud transmission.
