With the evolution of EE architecture, 10Base-T1S (in-vehicle Ethernet) and CAN FD have become the two most common communication protocols in current vehicle networks. Traditional approaches often require engineers to configure multiple standalone devices to achieve simultaneous monitoring and simulation of both networks, increasing system complexity and testing costs. To help users develop and validate automotive networks more efficiently, TOSUN officially introduces the TC1052—a portable communication tool integrating 10Base-T1S and CAN FD to USB conversion.

Products
TC1052 is a communication tool launched by TOSUN, featuring an integrated 1-channel 10Base-T1S and 2-channel CAN FD to USB interface...
Users can transmit raw frame data from 10Base-T1S or CAN FD networks to a PC via the USB interface using this device, or send raw frame data from the PC to 10Base-T1S or CAN FD networks. Combined with TSMaster software, the TC1052 device supports monitoring, emulation, analysis, and testing of Ethernet data, and enables protocol functions such as DoIP and SOME/IP.

Beyond its core 10Base-T1S communication capabilities, the TC1052 also features two CAN FD bus interfaces with a maximum data rate of 8Mbps. It supports loading DBC and ARXML database files, enabling users to monitor, analyze, and simulate CAN FD bus data. Additionally, it supports UDS diagnostics, ECU flashing, and CCP/XCP calibration functions.
Typical application
- Vehicle-Level CAN (FD)/T1S Network Synchronized Data Acquisition and Analysis
- Simulation, Testing, and Diagnostics for Intelligent Domain Controllers (Cockpit, Intelligent Driving, etc.)
- Developing a Highly Reliable Automated Testing System and Durability Test Bench
- Vehicle diagnostics, ECU calibration, and software flashing

Product Features.
- Microsecond-level hardware message timestamps provide a precise timing reference for high-level simulation and diagnostics.
- USB 2.0 driver-free design, plug-and-play on Windows/Linux, with excellent system compatibility.
- CAN channels feature DC2500V isolation and automotive-grade quality design, withstanding harsh operating conditions.
- CAN features a built-in 120-ohm terminating resistor that is software-configurable, easily adapting to various network topologies. 10Base-T1S incorporates a built-in 100-ohm terminating resistor that is software-configurable, supporting flexible software configuration of node IDs, node count, and timeout parameters to effortlessly build T1S networks.
- Fully supports mainstream file formats such as DBC, seamlessly integrating with all advanced features of TSMaster; hardware captures raw Ethernet packets, enabling simulation, analysis, and testing of upper-layer protocols in conjunction with TSMaster.
- Integrated core functions including BLF data logging and playback, UDS diagnostics, CCP/XCP calibration, and Flash Bootloader
- Provide cross-platform secondary development interfaces to meet deep customization needs.
