Frequently Asked Questions for USBCAN-II FD
Q
Does it support CAN FD, and how does it differ from the II C or II Pro?
▼
Does it support CAN FD, and how does it differ from the II C or II Pro?
Yes, the II FD is our dedicated CAN FD model supporting up to 5 Mbps (both ISO and Non-ISO). The II C and II Pro only support standard CAN 2.0A/B. If you need to analyze high-speed automotive or industrial CAN FD networks, the II FD is the direct choice.
Q
Do I need to wire external 120Ω resistors for a loop test?
▼
Do I need to wire external 120Ω resistors for a loop test?
No. Unlike the I Pro (single-channel) and older II C models, the II FD has built-in 120Ω terminal resistors for both channels, controlled independently via DIP switches (R1/R2). You just flip the switch to ON for self-reception testing.
Q
Why does ECANTools show "Open Device Error"?
▼
Why does ECANTools show "Open Device Error"?
Usually due to incorrect device type selection or driver issues. Ensure you select "USBCAN-FD" in the software dropdown (not USBCAN-I or II). Check Windows Device Manager for any yellow exclamation marks on "GC-TechUSBCANFD-IDevice" and reinstall if necessary.
Q
How to set custom baud rates outside the standard list?
▼
How to set custom baud rates outside the standard list?
The CAN controller uses a 24 MHz clock. While ECANTools provides standard baud rates, calculating custom values requires the 24MHz formula. For non-standard rates, please contact our support to calculate the exact timing parameters, as manual input is not supported directly in the GUI.
Q
How many devices can I connect to one PC for multi-channel testing?
▼
How many devices can I connect to one PC for multi-channel testing?
You can connect up to 8 identical USBCAN devices simultaneously (e.g., 8 x II FD = 16 channels). Note that the driver does not allow opening the same device across multiple processes—call OpenDevice once in your main application.
Q
My C#/Python application hangs when using the Receive function. Why?
▼
My C#/Python application hangs when using the Receive function. Why?
If Wait is non-zero and called in the main thread, it will block and freeze your app. For polling, set Wait = 0. The II FD driver provides a 100,000-frame software buffer and a specific nFrames = 0 trick to check notifications without blocking. Also, disable Windows Sleep/Standby to prevent hardware buffer overflow.
