# CP210x VCP Driver Installation Guide

### **In This Guide**

we explain how to install the **CP210x VCP driver**, which is required to configure or receive data from **GrowSpace UWB devices** (Tags, Anchors, and Listeners) via USB connection to a PC.\
\
This manual covers why the driver is needed and provides step-by-step instructions for downloading and installing it.

***

### What Is a USB to UART Driver?

GrowSpace devices communicate using serial communication.\
However, most modern PCs no longer have a built-in serial (RS-232) port, so they can't connect directly.\
\
To solve this, the device includes a **USB to UART (serial conversion) module**, which allows the PC to recognize the USB connection as a **virtual COM port**.\
\
The software required for this is the **CP210x VCP driver**.

***

### What Is the CP210x VCP Driver?

The **CP210x VCP (Virtual COM Port) driver** allows a USB device to function like a serial (COM) port.\
\
It is required for communication between GrowSpace UWB devices and your PC.\
Once installed, the device will appear as a **“COMx” port** in your system.

※ If the driver is not installed, the device will not be recognized by the web setup tool or configuration software.

***

### **Before You Begin Installation**

* **Operating System**: Windows 10 / 11
* **Administrator Rights**: Required during installation
* **Internet Connection**: Needed for downloading the driver
* **Web Browser**: Chrome is recommended (for using the web setup tool)

### Verifying Successful Installation

To check if the driver was installed correctly, follow these steps:

#### How to Check

1. Press **Win + X**, then click **Device Manager**
2. Expand the **Ports (COM & LPT)** section
3. If you see **`Silicon Labs CP210x USB to UART Bridge (COMx)`**, the driver has been installed successfully

※ The port may appear as “COM3,” “COM4,” etc. — the number may vary depending on your system.

***

### Troubleshooting Installation Issues

If the device is not recognized or the COM port does not appear after installing the driver, check the following:

#### 1) Reinstall the Driver

* In **Device Manager**:\
  Right-click on `Silicon Labs CP210x USB to UART Bridge` → Select \[**Uninstall device**]
* Then, run the driver installer again to reinstall it.

***

#### 2) Try a Different USB Port

* Some USB ports may not work reliably.\
  → Disconnect and try a different USB port, then check again.

***

#### 3) Check for Windows Updates

* If your OS is outdated, the driver may not install properly.
* Apply the latest Windows updates and try the installation again.
