- Ensure the USB cable is securely connected to both the device and the PC.
- Verify that the PWR indicator is lit. If not, check the USB connection or try a different USB port.
- Reinstall the device drivers from the Waveshare Wiki.
- No CAN Communication:
- Check the physical connections to the CAN bus terminals (H, L, G) for correct polarity and secure wiring.
- Verify that the 120Ω terminal resistors are correctly enabled or disabled according to your network's requirements.
- Ensure the baud rate configured in the software matches the baud rate of your CAN network. Use the auto-detection feature if unsure.
- Check the SYS indicator. If it is continuously lit, there is a bus error. Investigate the CAN network for issues such as short circuits, open circuits, or incorrect termination.
- Confirm that the CAN1/CAN2 indicators are blinking when data is expected. If not, check software configuration and network activity.
- Mathata a Software:
- Ensure you are using the latest version of the CAN FD Tools software and drivers from the Waveshare Wiki.
- Restart the software and/or your computer.
- For Linux systems, ensure all necessary dependencies are installed as per the Wiki instructions.
