Given the age of this hardware (circa 2010-2015), many users ask if they should hunt for a driver or replace the system.
Choose the driver if: Your school has a budget of $0, the board physically looks fine, and you are using Windows 10.
Replace the hardware if: You are on Windows 11, you have lost the proprietary pen, or the IR receiver has dead zones. Refurbished USB IR receivers cost $50-$100 on eBay, but modern USB touch overlays for the same board cost $300 and require no special drivers.
In the world of industrial automation and legacy computing, certain devices achieve a cult status for their reliability and specific utility. The ACT-IR2012UL 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.
Before diving into the specifics of the ACT-IR2012UL driver, 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).
However, without the correct driver, this sophisticated piece of hardware becomes a useless, unrecognized USB device. This article provides a definitive resource for finding, installing, and troubleshooting the ACT-IR2012UL driver across various Windows operating systems.
Cause: Windows is assigning a generic HID driver instead of the ActivDriver.
Solution:
The ACT-IR2012UL driver is more than just a file—it is the key to unlocking reliable long-range infrared communication from a USB port. While Microsoft and hardware vendors have moved on, the industrial and retro-computing communities continue to depend on this device. act-ir2012ul driver
By following the identification, download, and installation steps in this guide—paying special attention to 64-bit Windows signature issues—you can resurrect your IR2012UL and connect to legacy equipment that has no other digital lifeline.
Remember: Always scan legacy drivers with antivirus software, and prefer virtual machines for running untrusted driver packages. The ACT-IR2012UL may be a relic, but with the right driver, it remains a remarkably capable tool.

ACT-IR2012UL is a high-speed USB-to-IrDA adapter used for wireless data transfer between PCs and IrDA-enabled devices like data loggers, PDAs, and industrial instruments. ACT-IR2012UL Driver Support Windows 7 & Older : The adapter features Plug-and-Play (PnP) support using native Windows drivers. Windows 10 & 11
: While compatible, these operating systems may require a manual driver installation using the TSPack driver from ACTiSYS. Legacy Hardware Note
: Older units may contain an EOL (End-of-Life) IC that does not support Windows 10. If your serial number indicates an older model, you may need a newer adapter. How to Obtain the Driver
ACTiSYS typically does not provide direct public download links for the latest Windows 10/11 drivers. To get the correct driver for your specific hardware version: Locate Serial Number : Check the physical label on your IR adapter. Contact Support : Email the ACTiSYS technical support team at tech-support@actisys.com to request the updated TSPack driver or a workaround solution. Manual Installation : If you have the driver files, go to Device Manager
, right-click the device, and select "Browse my computer for driver software" to point to the unzipped driver directory. Product Features Given the age of this hardware (circa 2010-2015),
: Supports SIR (9.6k–115.2kbps), MIR (1.152Mbps), FIR (4Mbps), and VFIR (16Mbps).
: Draws power directly from the USB port; no external supply needed. Compatibility
: Works with any IrDA-capable notebook, printer, or medical/industrial instrument. ACT-IR2012UL - ACTiSYS Corporation
ACT-IR2012UL is a high-speed USB-to-IrDA (Infrared) adapter from ACTiSYS Corporation. It is primarily used for bidirectional communication between a PC and medical devices, such as Automated External Defibrillators (AEDs). Driver Compatibility & Installation
Operating Systems: The device officially supports Windows 98SE through Windows 11, including 64-bit versions and Windows Server 2003.
Windows 10/11 Support: While listed as compatible, standard Windows 10/11 drivers may require a "workaround solution." Users are encouraged to email ACTiSYS Tech Support for the specific Windows 10/11 workaround.
Mac OS: There are known issues with the Mac OS IrDA stack. It is highly recommended to contact support before attempting to use the device with Mac.
Automatic Installation: For supported legacy systems, the installer typically runs from a driver CD and completes without user action before you plug in the dongle. Key Benefits Speed: Supports full IrDA speeds from 9.6K to 4M bps. Performance: Users have reported that the ACT-IR2012UL Cause: Windows is assigning a generic HID driver
is 5 to 7 times faster for medical device applications compared to older models like the ACT-IR2002UL.
Bidirectional Support: Unlike some legacy adapters that only allow data downloads, this model supports both uploading configuration data and downloading logs. Troubleshooting & Tips
BIOS Settings: Ensure that the computer's USB port is enabled in the BIOS settings before use.
Verification: After installation, the device should appear under Infrared devices in the Windows Device Manager.
IrComm/OBEX: The adapter supports Windows 7 through 11 (32- and 64-bit) specifically for IrDA-OBEX applications.
For long-term reliability in environments where future OS support for IrDA may be uncertain, the manufacturer also recommends the ACT-IR100UDv3-XX as a stable alternative. ACT-IR2012UL - ACTiSYS Corporation
ACT produced several variants of the IR2012 series. Look at the label on the device:
The driver package is usually identical for all UL variants, but it's best to verify with the exact part number.
