New Products | TOSUN Technology Multi-Channel CAN FD to USB/WIFI Device, Solving Proximity Wireless Communication Problems

New Product Release

In January 2024, TOSUN Technology continuously released FlexRay series product TP1034 and Ethernet series product TP1051, and last week released multi-channel bus logger product TLog1004. on January 19, TOSUN Technology launched another 2/4-channel CAN FD to USB and WIFI tool to solve the problem of wireless communication in the near distance.


1. Product profile

TC1113B and TC1114B are 2/4-channel CAN FD bus to USB and WIFI tools introduced by TOSUN Technology, CANFD bus rate up to support 8M bps, the product uses a high-speed USB2.0 interface to connect with the PC, the OBD port to connect with the car end, support for the WIFI function, the Windows system drive-free design makes the device has excellent system Windows driverless design makes the device have excellent system compatibility.

Together with the powerful TSMaster software, which supports loading DBC and ARXML database files, it can easily monitor, analyze, and simulate CAN FD bus data, as well as support UDS diagnostics, ECU flashing, and other functions.

WIFI mode is recommended for message listening, diagnostics, not for emulation.

Secondary development API for Windows and Linux, which can support various development environments, such as C++, C#, LabView, Python, etc. Easy to integrate into various test systems, efficient and easy to use.

2. Typical applications

  1. OBD data viewing and analysis
  2. Wireless transmission of OBD data
  3. DTC fault viewing and clearing
  4. Vehicle/ECU flashing
