AvaSoft does not recognize my spectrometer, what can I do?

First, check whether the spectrometer is powered externally or by USB.

  • If the spectrometer is powered by USB, then check whether the green LED on the front of the spectrometer indicates it is on. Make sure the sound of your computer is on as well. When you connect the spectrometer to your computer, you should hear a sound. That sound means the computer recognizes the spectrometer.
  • If the board is externally powered, check the 12V adapter. Check the voltage of the main source. Make sure the power switch at the back of the spectrometer is switched to the external power position. Check whether the green LED at the front of the board is on. If the green LED won’t turn on, install the driver and check again.

If you’re still experiencing problems after following these instructions, please call us or send an e-mail to and we will help you figure it out.
