Test vehicles require not only complete data recording, but also real-time analysis or live trace. The point-to-point communication principle of Automotive Ethernet, which is widely used in real vehicles, poses a great challenge to the installation of test equipment in test vehicles.
With the dynamic TAP function of the ZD Datalogger 3 series:
• Any Automotive Ethernet communication (or CAN, LIN, FlexRay bus communication) can be redirected to a specified data logger without affecting the complete recording by the data logger.
• Customers can switch any specified data channel in real time via software.
• The Ethernet interface trace is the original Ethernet packet, allowing customers to use Wireshark, CANoe, or other data analysis tools for real-time data analysis.
• Other bus forwarding to the management Ethernet bus trace is ASAM CMP protocol message, supporting any ASAM CMP compliant client tool.
This helps customers overcome multiple pain points:
• The exclusivity of Ethernet bypass devices makes it difficult for data loggers and simulation boxes to coexist.
• The complexity of vehicle Ethernet wiring makes temporary wiring or rewiring difficult.
• Power issues for multiple test devices in a vehicle.

As the development of in-vehicle electrical architectures and ADAS functions becomes more complex, many functions require collaboration and co-development by teams in different locations. How to synchronize the real-time status of in-vehicle function development on a limited number of test vehicles has become a major challenge for remote collaborative development. ZD's data loggers can record all in-vehicle bus data and have established a remote access channel, allowing remote teams to conveniently share raw data on the test vehicle. In addition, the combination of the data logger's custom filter and trigger functions makes this remote data sharing even more efficient.
