🔎 Top 5 FAQs (Most Discussed Recently) — TC1014 Multi‑Channel CAN FD Bus Tool

1) What are the core capabilities of the TC1014 for automotive CAN FD testing?

Answer:
The TC1014 is a 4‑channel CAN FD‑to‑USB interface device designed for automotive testing, calibration, and development. It supports ISO/non‑ISO CAN FD protocols with up to 8 Mbps data rates, μs‑level hardware timestamps, software‑configured 120Ω termination, and high isolation. It also enables supported data logging (BLF/ASC), DBC/ARXML loading, UDS diagnostics, CCP/XCP calibration, and secondary development via APIs for Windows and Linux.

2) Does the TC1014 require a USB driver on Windows or Linux?

Answer:
On Windows, the TC1014 uses a driver‑free (plug‑and‑play) USB 2.0 interface, meaning it is automatically recognized without manual driver installs. On Linux, it typically works with provided libraries (e.g., libtscan / tsdev) and may require loading specific modules or using APIs.

3) Can TC1014 be used for both real‑time testing and offline analysis?
