The Acer Nuvoton CIR Transceiver driver enables Windows to communicate with the consumer infrared hardware built into compatible Acer computers. It helps the system recognize supported infrared remote-control commands, allowing you to control media playback and other assigned functions without using a keyboard or mouse.

Key Features

• Infrared remote input: Lets compatible applications respond to commands from a supported infrared remote, such as play, pause, and navigation.
• Hardware recognition: Identifies the CIR transceiver in Windows so the system can use the correct driver rather than leaving it listed as an unknown device.
• Integration with Acer hardware: Provides the software interface for the Nuvoton infrared component fitted to supported Acer models.
• Windows-specific support: Use a package matched to your Acer model and Windows 11, 10, 8, or 7 installation. Driver availability and supported functions can vary by model and operating system.

How to Install

1. Confirm your computer and Windows version. Find your Acer model number and check whether Windows is 32-bit or 64-bit. Make sure your computer includes the Nuvoton CIR hardware; installing this driver will not add infrared capability to a system without it.
2. Choose the matching driver package. Download the Acer Nuvoton CIR Transceiver driver intended for your model and operating system. Do not assume a package made for an older Windows release will work on Windows 11 or 10.
3. Extract and run the installer. If the download is compressed, extract it to a folder first. Launch the included setup program, approve the administrator prompt if requested, and follow the on-screen instructions.
4. Use Device Manager if needed. If there is no installer, locate the CIR transceiver or corresponding unknown device in Device Manager. Select “Update driver,” choose “Browse my computer for drivers,” and point Windows to the extracted folder. Let Windows check for a compatible match.
5. Restart and test the remote. Reboot if prompted, then try the remote in an application that supports its commands. If there is no response, check the remote’s batteries, keep the infrared receiver unobstructed, and confirm that Device Manager shows no warning for the device.

Common Issues and Fixes

• Install fails or rolls back: Use the Acer package that matches your exact model and Windows version/architecture. Run the installer as administrator, disconnect other IR receivers, reboot, then retry.
• Device not detected: Check BIOS/UEFI for a disabled CIR/IR or “Wake on IR” option and enable it. In Device Manager, scan for hardware changes and show hidden devices; the transceiver may appear under Human Interface Devices or USB controllers.
• Version conflicts with Windows’ generic IR driver: Uninstall the existing CIR device and select “Delete the driver software,” reboot, then install the Acer Nuvoton driver. If Windows reinstalls a generic driver, roll back to the Acer version and confirm the device status shows no errors.
