U2IrDA Mini — 4 Mbps FIR USB IrDA Adapter

Overview

The U2IrDA Mini is a compact USB-to-Infrared (IrDA) adapter that supports Fast Infrared (FIR) data transfer at up to 4 Mbps. It enables IrDA-capable devices (phones, PDAs, some printers, and legacy equipment) to communicate wirelessly with modern computers that lack native infrared ports. The adapter is plug-and-play on supported systems and is aimed at users maintaining legacy device connectivity or transferring small files and synchronizing settings.

Medical Equipment: Often used to pull data from heart rate monitors or defibrillators in clinical settings. Driver & Compatibility Notes UIR-33 - USB to IrDA adapter - Tme.eu

Effective transmission distance of up to 1 meter within a 30-degree viewing angle. Fully bus-powered—no external power bricks required. Visual Feedback: U2IrDA Mini 4 MBPS FIR USB IrDA 20

The Critical “4 Mbps FIR” Advantage

Why not just use a slower, cheaper 115.2 kbps dongle? Because many industrial devices require FIR for firmware flashing. For example, a medical glucometer that stores 500 readings will transfer data in 12 seconds over 4 Mbps FIR versus nearly 3 minutes over SIR. The U2IrDA Mini explicitly supports the 4 Mbps FIR mode, which requires precise timing and a clean USB host controller. Medical Equipment : Often used to pull data

Buy from a seller who provides a datasheet and confirms 4 Mbps FIR operation with screenshots.

High-Speed Transfer: Supports Fast Infrared (FIR) modes with speeds up to 4 Mbps, significantly faster than the standard 115.2 Kbps of older SIR devices.
