Use Cases and Applications

Step-by-Step for Windows 10/11:

1. Plug in the U2IRDA. The OS should detect a “USB-IrDA Adapter” or “SigmaTel USB-IrDA Adapter.”
2. Driver automatic install – Windows Update may fetch the generic IrDA driver. If not, download the driver from the manufacturer (usually based on the SigmaTel STIR4210 or National Semiconductor PC87111 chipset).
3. Locate IrDA settings (Windows 10/11 hides them). Type control → Run → Control Panel → View by: Large icons → Infrared (or “Wireless Link”).
4. Set speed: In the Infrared tab, set “Maximum connection speed” to 4 Mbps (Fast Infrared).
5. Enable file transfer: Check “Allow infrared file transfer” and set a default receive folder.
6. Test alignment: On your legacy device, initiate an IrDA send. The U2IRDA’s red activity LED (if present) will flicker.
