Installation Steps

Confirm the exact DAPPRA PLC cable model or chip type.
Download the corresponding Windows driver from the table above.
If the file is compressed, extract the ZIP package first.
Run the driver installer and follow the on-screen instructions.
Reconnect the USB cable and open Windows Device Manager.
Confirm that a COM port appears, then select this COM port in your PLC software.

Device Manager Reference

Before CH340 driver Device Manager may show a yellow exclamation mark and USB2.0-Serial.

After CH340 driver Device Manager may show USB-SERIAL CH340, followed by a COM port number.

Before FT232 driver Device Manager may show FT232R USB UART.

After FT232 driver Device Manager may show USB Serial Port, followed by a COM port number.

COM3 is only an example. The actual COM port number can be different on every computer.

PLC Cable Driver FAQ

Quick answers for common driver installation and communication problems.

How do I know whether my cable uses CH340 or FT232?

Plug the cable into the computer and open Device Manager. If it shows USB2.0-Serial or USB Serial, try CH340. If it shows FT232R USB UART or USB Serial Port with FTDI chip information, use FT232.

Why is there a yellow exclamation mark in Device Manager?

This usually means Windows has detected the USB device but the correct driver is not installed. Install the matching driver and reconnect the cable.

Why is my COM port different from the example?

The COM number is assigned by Windows. COM3 is only an example; use the actual COM port shown on your computer.

Can I use the USB-ETH driver for other PLC cables?

No. The USB-ETH driver is only for the DAPPRA USB-ETH communication cable model and is not applicable to other communication cables.

What should I do if the driver cannot be found automatically?

Right-click the unknown device in Device Manager, choose Update Driver, and select the folder where the extracted DAPPRA driver files are located.
