  1. Disconnect the PS-2100A and close DataStudio.
  2. Connect the PS-2100A USB Link to your computer without a sensor (or PS-2158) connected.
  3. Go to and download the UsbLink2.hex file
  4. Save it to the C:\Program Files\DataStudio\Plugins\DataSheets directory (replace the same-named file that already exists in the directory)

  6. When prompted to update the firmware on the PS-2100A, click Yes.
After the firmware is updated, the PS-2100A should give correct sensor data.
