Xinje PLCs (Programmable Logic Controllers) are widely used in industrial automation due to their cost-effectiveness and reliability. To program or monitor these PLCs, you must connect them to a PC via USB. However, simply plugging the device in is often not enough; you must manually install the specific USB driver to ensure the programming software (Xinje XCP Pro) can recognize the hardware.
This guide walks you through the installation process for Windows operating systems.
Critical Warning: Installing the wrong driver for your series can cause Blue Screen of Death (BSOD) or prevent the programming software from seeing the PLC. xinje plc usb driver install
After installation, under Ports (COM & LPT) in Device Manager, you will now see “XINJE USB Serial Port (COMx)” where x is a number (e.g., COM5, COM7).
Pro tip: If you plan to use multiple XINJE PLCs on the same PC, note the COM number. You can right-click > Properties > Port Settings > Advanced to change the COM number to avoid conflicts (e.g., change from COM14 to COM3). Xinje PLCs (Programmable Logic Controllers) are widely used
Do not use generic USB-to-serial drivers. Xinje PLCs use a proprietary driver, often based on a Silicon Labs CP210x or a custom Xinje driver, depending on the PLC series.
Connect your Xinje PLC to your computer using a USB cable. After installation, under Ports (COM & LPT) in
There are two ways to install the driver, depending on how Xinje packaged the software version you are using.
| Error Code | Text | Likely Cause | Fix | | :--- | :--- | :--- | :--- | | Code 32 | Driver disabled in registry | A previous failed install left a flag. | Manual registry cleanup or System Restore. | | Code 39 | Driver corrupted | Windows update overwrote the driver. | Reinstall XINJE driver, then block Windows driver updates via Group Policy. | | Code 52 | Unsigned driver | Windows 10/11 secure boot. | Disable driver signature enforcement (see Part 2). | | 43 | Port reset failed | Power surge or faulty PLC USB chip. | Test PLC on another PC. If same error, RMA the PLC. |
Now that the driver is installed, you must tell the programming software which port to use.
