K-Touch 1xEV-DO NMEA Device (COM4) Driver

The K-Touch 1xEV-DO NMEA Device (COM4) driver helps Windows recognize the USB-connected NMEA serial interface associated with compatible K-Touch hardware from Beijing Tianyu Communication Equipment. It is intended for users who need to restore device detection, resolve a missing-driver warning, or allow compatible software to access the device’s NMEA data interface.

Key Features

• USB interface recognition: Enables Windows to identify the supported NMEA interface rather than leave it listed as an unknown device.
• Serial communication support: Makes the interface available through a virtual COM port for applications designed to read NMEA data, commonly used for positioning information.
• Windows compatibility: Listed supported systems include Windows 10, Windows 8.1, Windows 7, Windows Vista, and Windows XP. Check the individual package for operating-system and 32-bit or 64-bit requirements.
• Device troubleshooting: Installing a matching driver may resolve recognition or communication problems caused by a missing, incorrect, or damaged installation.

How to Install K-Touch 1xEV-DO NMEA Device (COM4) Driver

1. Check your device and Windows version. Open Device Manager and locate the NMEA interface, which may appear under Ports (COM & LPT) or Other devices. Compare its hardware IDs with those supported by the driver package.
2. Select a compatible package. Before starting the K-Touch 1xEV-DO NMEA Device (COM4) driver download for Windows, confirm the supported OS and system architecture. If you need Windows 10/11 compatibility, note that Windows 10 is listed, but Windows 11 support is not confirmed.
3. Download and extract the files. Choose a trusted source, verify the publisher where possible, and scan the package. A free download should not require unrelated utilities or paid driver-update software.
4. Install the driver. Run the supplied installer if included. Alternatively, right-click the device in Device Manager, select Update driver, and browse to the extracted driver folder. Follow the prompts without bypassing Windows security warnings.
5. Verify the connection. Restart if requested, reconnect the hardware, and check that Device Manager shows no warning icon. Select the assigned COM port in your application; Windows may assign a number other than COM4.

Keep the driver updated when a compatible release addresses a problem or improves support for your system. Before you update, verify that the latest version explicitly supports your hardware and Windows edition, and retain the working package in case you need to roll back.
