ZD Datalogger 2 Series

The ZD Datalogger 2 Series has been specifically designed for heterogeneous vehicle bus systems, integrating various bus interfaces such as Gigabit Ethernet, FlexRay, CAN/CAN FD, LIN, and serial communication. It supports SSD storage from 500GB to 4TB and is suitable for various applications in automotive research and development, such as ECU development, system integration, and full vehicle endurance testing. This series offers real-time data acquisition, stable and accurate data recording with time-stamping support. Its automotive design, combined with sleep and wake-up functions, ensures very low power consumption and heat dissipation, making it suitable for high voltage, such as in electric vehicles, extreme temperature, and vibration scenarios. Device and data management can be performed using the included Trace Client software. ZD also provides a Python SDK compatible with Windows and Linux operating systems for fast device integration.

Application Range

Scenario 1

Vehicle Bus Data Acquisition

During the vehicle development integration testing phase, systems interact and coordinate via bus signals. Capturing and analyzing bus signals, including timing, error assessment, and full-cycle lossless acquisition, is essential at this stage. The ZD Datalogger 2 Series supports 12 CAN/CAN FD channels, 10 LIN buses and 10 Ethernet ports, with network synchronization of two ZD-Dataloggers enabling full-vehicle data acquisition and timestamp synchronization. Additionally, real-time monitoring of up to 8 CAN bus signals can be achieved using the ZD Box2i, the simulation platform and the corresponding VBT software.

Scenario 2

Laboratory Test Setup

In laboratory scenarios, the services of the ZD Datalogger 2 Series capture bus data, control unit debugging information, and log datas, meeting the requirements of vehicle data acquisition. Additionally, they impose higher demands on managing multiple devices within a local network. The ZD Datalogger 2 Series supports DHCP client and DHCP server modes. The device can be configured in DHCP server mode, allowing testers to access data in DHCP client mode. In a laboratory environment with multiple ZD Dataloggers, it can be operated in DHCP client mode. A single server assigns IP addresses to simplify the management and access to devices within the LAN.

Scenario 3

Case Study on Data Acquisition in Automotive Ethernet

The ZD Datalogge r2 series adapts to the star topology of Automotive Ethernet and integrates a switch function to ensure seamless point-to-point communication. Utilizing FPGA technology, it achieves fast and reliable data acquisition. Additionally, the ZD Datalogger2 series provides two standard Gigabit Ethernet ports for data acquisition, which not only enable direct connection to the standard Ethernet debugging port of electronic control units (ECUs), but can also be connectedt to the vehicle’s Ethernet interfaces through the supplementary products of the ZD-Converter Series. This flexibility makes them suitable for a wide range of application scenarios.
