ZD Box Series

Multi-bus simulation interface · Rest-bus and network simulation

The ZD Box series is ZD's simulation interface device for vehicle bus simulation and rest-bus simulation. It covers a wide range of bus protocols, deploys quickly on Windows and Linux with no driver installation, and offers excellent compatibility. It provides microsecond (μs) hardware timestamps, hardware buffering that prevents frame loss, software-controlled 120 Ω termination and DC 3750 V CAN channel isolation, for use by R&D, testing, production and after-sales teams.

Key Features

01Broad bus protocol coverage

Supports CAN 2.0 (100 Kbps–8 Mbps), CAN FD, LIN 1.3/2.0, FlexRay, 100/1000M automotive Ethernet and Ethernet standards such as DoIP, SOME/IP and 802.1Q.

02μs-level hardware timestamps

Microsecond hardware message timestamps meet high-precision bus analysis and testing requirements.

03No frame loss with hardware buffering

Hardware message buffering ensures that no frames are lost when logging under heavy bus load.

04Software-controlled termination

Built-in 120 Ω termination, configurable in software to suit different bus topologies.

05DC 3750 V channel isolation

CAN channels provide DC 3750 V electrical isolation, protecting both the device and the system under test.

06Driver-free deployment

Runs on Windows and Linux without drivers, supports a range of APIs and custom development, and works seamlessly with host software such as ZD VBT.

Applications

REST-BUS

Rest-bus simulation

REST-BUS SIMULATION

During vehicle network development, when some ECUs are not yet available, the ZD Box series simulates the existing bus nodes in place of the real ones to complete network communication validation, supporting early bus data analysis, ECU development and functional testing.

Node simulation: CAN/CAN FD, LIN, FlexRay and Ethernet node simulation
Cold start: FlexRay channels (A and B) support cold start
