This simple encoding allows a microcontroller to drive three independent loads using just 6 GPIO pins (2 per channel) plus an enable line.
Below is a complete technical guide covering its identity, hardware specifications, driver installation, and advanced configuration.
The PI40952 3X2B is a robust, versatile driver designed for those who need reliable power management in a small footprint. Whether you are repairing a piece of industrial equipment or designing a new lighting solution, understanding the thermal and communication requirements of this chip is the key to a successful project.
Whether you are connecting CNC machinery, vintage receipt printers, barcode scanners, or telemetry systems, installing the precise underlying driver is critical to overcoming the notorious "PCI Serial Port" yellow warning triangle in your system properties. Hardware Breakdown: Understanding the PI40952-3X2B Board
Modern motherboards rarely include native COM ports. For hobbyists working with microcontrollers or professionals using legacy diagnostic tools, this card provides a more stable and high-speed alternative to flaky USB-to-Serial adapters. The 128-byte FIFO ensures smooth data handling even under load.

was distributed by original equipment manufacturers (OEMs), there is no single, dedicated standalone website for the card. Users can reliably source operational drivers from several major repositories: Delock PCI Express Card to 2 x Serial
The low-profile design makes it versatile for mini-PCs. Cons:
If you are creating a custom board, follow these layout guidelines: This simple encoding allows a microcontroller to drive
If you have a high-end modern PC but still need to talk to a 20-year-old CNC machine or a scientific scanner, this card is your translator. Design & Fit : It uses a compact Low Profile
Most modern Windows versions (10/11) may automatically detect and install the driver through Windows Update once the card is seated. Shopping Options
Once you have identified the chipset or sourced the appropriate installation package, follow these sequential steps to install the driver:
However, to get this hardware communicating seamlessly with modern operating systems like Windows, locating and installing the correct is essential. Without it, your OS will not recognize the PCIe card, leaving your legacy equipment dead in the water. Understanding the PI40952 3X2B Adapter Whether you are repairing a piece of industrial
Depending on your specific version of the card, you’ll likely need one of these two driver sets to get those RS-232 serial ports humming:
By locating the correct and properly mapping your legacy equipment, you can save hundreds or thousands of dollars by continuing to use older, fully functional industrial or business peripherals on modern workstations.
