FiX™ 82 & 86 Firmware Update for TüN™ 2.0 Software

FiX™ 82 and 86 require firmware updates to take advantage of TüN™ 2.0 software. Follow the steps below to complete the update procedure.


Important: Make sure to exit TüN™ 2.0 before proceeding.

  1. Download the latest firmware for your FiX™ model to your PC. Choose one of these links:
    FiX-82 Firmware (V0116)
    FiX-86 Firmware (V010C)


  2. Unzip the downloaded FiX™ firmware file. The contents will include one file with a ".dfu" extension and one with a ".dsp" extension. The firmware update will require both of these files.
