IFC200/IFC202/IFC300/IFC400 Troubleshooting

Posted on

I’m having trouble with my Interface cable (IFC200, IFC202, IFC300, IFC400).

MadgeTech 4:

Please follow the steps below to install the USB drivers:

  1. Your interface cable (for example, IFC200, IFC300, IFC400, RFC1000) should be unplugged.  
  2. Download the latest USB drivers  Save this in a location that is easy to find such as your desktop.
  3. Locate the “” file that you just downloaded. Right-click the file and select Extract all and follow the prompts to extract the contents of the zip file to a folder.
  4. Open the new folder that you extracted (the folder will also be called USB-Drivers_w_64 but will not have a zip icon) and open it. Double-click “PreInstaller” to run the USB driver installer. Let it scan your computer and install the new drivers.
  5. Once it is successful you may plug your IFC back in (preferably to a different USB port than before) and wait for the blue light to come on.
  6. Launch the Software.
  7. Plug in your data logger.
