The Digitus USB Serial Converter connects compatible serial equipment to a computer through a USB port. Its driver allows Windows to recognize the adapter and create a virtual COM port that serial applications can use to communicate with connected devices. For Windows 11, 10, 8, or 7, choose a driver package that matches your adapter model and operating system.

Key Features

• Virtual COM port support: Makes the USB-connected adapter available as a serial port for compatible terminal software, configuration utilities, and other serial applications.
• USB-to-serial communication: Enables data exchange between your PC and compatible equipment, such as modems, industrial controllers, and diagnostic devices.
• Serial connection settings: Allows supported communication parameters, including baud rate, parity, and flow control, to be configured through Windows or your application.
• Windows device integration: Helps Windows identify the converter correctly so you can check its status and assigned COM port in Device Manager.

How to Install

1. Identify your adapter and Windows version. Check the model number on the Digitus USB Serial Converter or its packaging. Confirm whether your Windows installation is 32-bit or 64-bit, and select a package intended for that model and system.

1. Download and extract the driver. Save the matching package to your computer. If it is compressed, extract its contents before starting installation. Follow any included instructions about when to connect the adapter.

1. Install the driver files. Run the supplied installer if one is provided, approving the Windows administrator prompt when required. For a manual installation, open Device Manager, locate the converter or unidentified device, select Update driver, and browse to the extracted driver folder.

1. Connect the converter and verify detection. Plug it into an available USB port, then check Device Manager. A correctly installed adapter typically appears under Ports (COM & LPT) with an assigned COM number. Restart the computer if the installer requests it.

1. Configure and test your serial connection. Select the assigned COM port in your software and match the communication settings to the connected equipment. If communication fails, check the serial cable, device power, and port settings before reinstalling the driver.

Different Digitus adapters may require different driver packages, even when their product names look similar. Matching the exact model helps avoid installation errors and compatibility problems.

Common Issues and Fixes

• Driver install fails or rolls back: Disconnect the Digitus converter, run the driver installer as administrator, and reconnect only when prompted. If setup still fails, uninstall any previous USB-serial driver, reboot, then reinstall.
• Device not detected / no COM port: Try another USB port and cable, then check Device Manager under Ports (COM & LPT) or Unknown devices. Reinstall the Digitus driver and reboot; a missing COM port usually means the USB-serial driver did not bind.
• Version or COM-port conflicts: Remove old USB-serial drivers and hidden COM ports in Device Manager, reinstall the current Digitus driver, and assign an unused COM number if another adapter already holds the same port.
