NeXus-32: How to check the USB/Fiber connection

When the USB/Fiber connection fails, the NeXus-32 automatically tries to connect via Bluetooth. If that does not work, an error message will appear in BioTrace+. But because the FUSBI and Fiber cable are still connected, you might think you are recording via USB/Fiber.

Please check if the FUSBI is recognized correctly by the computer:


  • the FUSBI must appear in the Device Manager when it is connected to the computer via USB;

  • the green light on the FUSBI turns on;

  • one of the 'pins' inside the FUSBI shows a red LED light.

  • When the Fiber cable is connected, also one of the pins on the other end of the cable must show a red LED light.

  • When the the Fiber cable is plugged in the NeXus-32 and a recording is started, the word 'Fiber' appears on the NeXus-32 display.
    When the Bluetooth connection is used to record, the word 'Serial' appears on the display.
