BC125AT (COM5) Driver

The BC125AT (COM5) driver enables Windows to communicate with the Uniden America BC125AT handheld scanner through its USB connection. You need it if you want compatible programming software to recognize the scanner, manage channel settings, or resolve a missing USB serial connection. The “COM5” label identifies the serial port assigned by Windows; your computer may assign a different port number.

Key Features

• USB serial communication: Provides the connection that compatible scanner programming software uses to exchange settings with the BC125AT.
• Device recognition: Helps Windows identify the connected scanner as a serial device rather than leaving it listed as an unknown device.
• Programming software access: Makes an assigned COM port available so you can select the scanner’s connection in your programming application.
• Support for listed Windows releases: Intended for Windows 10, 8.1, 7, Vista, and XP, subject to the compatibility requirements of the specific driver package.

How to Install BC125AT (COM5) Driver

1. Check your system. Confirm your Windows version and whether it is 32-bit or 64-bit before choosing a BC125AT (COM5) driver download for Windows. For Windows 10/11 systems, note that Windows 10 is listed as supported here, but Windows 11 compatibility should be verified separately.
2. Get the correct package. Look for a free download from Uniden’s official support resources or another trusted source. Choose the latest version that explicitly supports your operating system and scanner.
3. Extract and install. Unzip the download if necessary, then follow the included instructions. If there is no installer, use Device Manager’s “Update driver” option and browse to the extracted driver folder.
4. Connect the scanner. Use a USB cable that supports data transfer. Follow the package’s instructions about when to connect the BC125AT, and allow Windows to finish detecting it.
5. Verify the connection. Open Device Manager and check “Ports (COM & LPT)” for the scanner’s assigned COM port. Select that same port in your compatible programming software; it may not be COM5 on every computer.

Keep the driver updated when a compatible release addresses a connection problem or supports a system change. Before you update, review the package’s compatibility notes and retain a copy of your working driver so you can restore it if needed.
