### Prompted install ###

If Windows prompts you to install a driver for a CP210x device (for example, when you plug the reader into your computer):

  1. Use the dialog to browse for the driver location
  2. Locate the driver folder (that you previously downloaded from Dropbox location)
  3. Follow the system prompts

### Manual install ###

  1. Using Windows File Explorer, locate the driver folder (that you previously downloaded)
  2. Determine if you have 32-bit or 64-bit Windows
  3. Double-click to run the .exe file named CP210xVCPInstaller_xnn.exe
  4. (where xnn is x64 for 64-bit and x86 is for 32-bit)
  5. Follow the system prompts

### Device Manager Driver Installation ###

In case the Prompted or Manual driver installations are not successful, the below instructions will walk you through setting up the driver manually from Device Manager. This method works on PC’s running Windows 7.

Step 1: Confirm 32 bit vs 64 bit

Step 2: Download RFID Reader driver folder to desktop

Folder: 2018 Windows Drivers CP210x

Step 3: Plug UHF RFID Reader into USB port on computer

(System tries to automatically install device driver)

Step 4: Note device driver did not successfully install

Step 5: Open Device Manager (while leaving RFID Reader connected)

  • Start – Open Control Panel
  • Select Devices and Printers – Device Manager

Step 6: Note the problem device under Other Devices > CP2102N USB to UART Bridge Controller

Step 7: Right-click on the problem controller and click Update Driver Software

Step 8: Browse my computer for driver software (option)

Look on the Desktop, select the Root Folder,  make sure Subfolder option is checked, select “Next”

Step 9: In device manager, Device is now working correctly

Step 11: Load the Reader application that came with the Reader and follow steps in the user manual

eChain USB Reader Application – Select Com Port, Select Connect, Select “Get” Firmware Version. If you get response version 1.9, then you have successfully connected to the reader.
Final confirmation is reading RFID tags.
