Due to driver signature enforcement, the legacy .sys file will be blocked. Here is the solution:
If the device does not plug-and-play, follow these steps to manually install the driver. Method A: Manual Driver Installation
: Requires a third-party software layer called IrComm2K . Note that IrComm2K does not support 64-bit operating systems . If your target industrial machinery relies strictly on 64-bit IrComm, the alternative ACT-IR100UD-v3 Intelligent USB-IrDA adapter must be used instead. 2. Windows 10 Workaround Restrictions
Before seeking a driver, one must correctly identify the hardware. Using , Linux lsusb , or macOS System Information , the Vendor ID (VID) and Product ID (PID) should be retrieved. For a hypothetical ACT-IR2012UL, the VID might correspond to ACTi or a generic IR controller (e.g., SigmaTel, SMSC). act-ir2012ul driver
If no driver is found, the device may be non-functional, counterfeit, or require a custom embedded driver.
For advanced users, the libircomm or irda-utils for Linux (or Windows via Zadig) can sometimes drive the chipset. Use Zadig to replace the driver with WinUSB or libusb and then map to a COM port via third-party bridging software. This is not plug-and-play.
Built on the ASIX/MosChip MCS7703 or MCS7840 controller platform. Interface: USB 1.1 / USB 2.0 compatible. Due to driver signature enforcement, the legacy
Before diving into the specifics of the , it is critical to understand what this hardware is. The device typically connects via a USB port (the "UL" suffix often denotes USB interface with low-profile or long-range capabilities) and emulates a standard serial COM port. It allows legacy systems that rely on IrDA (Infrared Data Association) protocols to communicate over distances far greater than standard IR ports (sometimes up to 1 meter or more).
Troubleshooting checklist
To help narrow down your specific issue, please let me know: Which version are you currently running? What error code or message does the Device Manager show? What specific device are you trying to connect to? Share public link Note that IrComm2K does not support 64-bit operating systems
: Supports SIR (9.6k–115.2kbps), MIR (1.152Mbps), FIR (4Mbps), and VFIR (16Mbps).
In the world of industrial automation and legacy computing, certain devices achieve a cult status for their reliability and specific utility. The is one such device. Manufactured by ACT (often associated with ACTiSYS or similar embedded solution providers), the IR2012UL is a high-performance, ultra-long-range infrared (IR) transceiver module. Unlike the common consumer IR blasters found in TV remotes, the IR2012UL is designed for industrial, medical, and serial communication applications.
Supports SIR (Slow Infrared) speeds up to 115.2 Kbps. Power: Bus-powered directly from the USB port. Operating System Compatibility
If the infrared connection drop-down menu disappears entirely from your Windows platform after a system update, Windows may have disabled the network stack components entirely.
