Understanding the PI40952-3X2B Driver: A Complete Guide The PI40952-3X2B is a common hardware identifier found on Delock PCI Express expansion cards. These cards are typically used to add legacy serial (RS-232) or parallel (LPT) ports to modern computers that lack them. If you have recently installed this card and your operating system hasn't automatically recognized it, you will likely need to install the specific drivers associated with its chipset. Hardware Specifications
Before downloading a driver, it is helpful to identify exactly what hardware you have. The PI40952-3X2B marking is most frequently associated with the following configurations:
Chipset: Often uses the Oxford OXPCIe952 or WCH CH382 controllers.
Interface: PCI Express x1 (compatible with x4, x8, and x16 slots).
Ports: Typically provides 2 x Serial RS-232 DB9 ports or a combination of serial and parallel ports.
Data Rates: Supports data transfer rates up to 230.4 Kbps for serial communication. Where to Download the PI40952-3X2B Driver
To ensure system stability, always prioritize official manufacturer sources over third-party driver "update" sites.
Delock Official Website: If your card is a Delock 89220 or similar, search for your specific model number on the Delock Support Page.
Chipset Manufacturer (WCH): If the card uses a WCH chipset, you can download the latest CH38XDRV.ZIP package, which supports Windows 7 through Windows 11.
Driver Scape/Third-Party: While sites like Driver Scape host these drivers, use them only if official manufacturer links are unavailable. Supported Operating Systems pi40952 3x2b driver
Most modern drivers for this hardware support a wide range of Windows environments: Windows 11 / 10 (32 and 64-bit) Windows 8.1 / 8 Windows 7 Windows Server (2012, 2016, 2019, 2022) Installation Steps
Insert the Card: Power down your PC and install the card into an available PCIe slot.
Download the Driver: Get the .zip or .exe file from one of the official sources listed above.
Run the Installer: If it's an executable (like CH35XDRV.EXE), run it and follow the prompts.
Manual Update: If you have a .zip file, go to Device Manager, right-click the "Unknown Device" (often listed under Multi-port serial adapters), select Update Driver, and point it to the extracted folder.
Verify: After a restart, the new COM or LPT ports should appear in your Device Manager under "Ports (COM & LPT)". Delock PCI Express Card to 2 x Serial

PI40952-3X2B Delock PCI Express card designed to add two external serial RS-232 ports to a PC. It is a practical solution for modern computers that lack legacy serial connections, allowing the connection of devices like scanners, printers, and mice. Bridging the Gap: The Delock PI40952-3X2B Adapter Card
In an era of USB-everything, legacy hardware often gets left behind. If you're managing industrial equipment, specialized scanners, or classic peripherals, the Delock PI40952-3X2B Adapter Card Understanding the PI40952-3X2B Driver: A Complete Guide The
is your bridge back to connectivity. This PCI-E card expands your system by providing two high-speed serial ports without taking up excessive space. Key Features Dual RS-232 Connectivity : Features two external 9-pin DB9 male serial ports. Low Profile Compatibility
: Comes with low-profile brackets, making it suitable for standard PCs and Mini-PCs alike. Reliable Performance
: Built on a stable chipset (often Oxford or WCH) that supports data transfer rates up to 230.4 Kbps Wide OS Support
: Compatible with Windows 7, 8.1, 10, and 11, as well as various Windows Server versions. Why You Need It
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. Quick Installation Guide Hardware Set : Power down your PC and insert the card into a free PCI Express x1 Driver Setup
: Windows 10 and 11 often detect the card automatically. For older systems, you can download the latest drivers from the Delock Service & Support Verification Device Manager
to confirm the two new COM ports are active and ready for use.

If you need a draft blog post on how to approach troubleshooting or identifying unknown driver chips like this one, I can write that for you instead. Just let me know.
I’m unable to generate a specific technical report for "pi40952 3x2b driver" because that exact identifier does not match any widely documented electronic component, IC, or driver module in public datasheets or technical databases (as of my latest knowledge update).
However, I can provide you with a template report for a generic “3x2-bit driver” (likely meaning a 3-input, 2-output or 3-channel, 2-bit parallel driver) and guidance on how to complete it with real data if you have access to the part or its datasheet.

As of 2025, the trend in embedded systems is towards higher integration and lower BOM count. The PI40952 3x2B driver fits this trend perfectly. However, keep these advanced tips in mind:
VEN_10EC)Based on the "3x2B" pattern, the PI40952 internally comprises three H-bridges (or three half-bridge pairs) with a common logic interface. It is designed to operate from 12V to 48V DC, with peak currents ranging from 2A to 5A per channel, depending on the package (likely a multiwatt or HTSSOP).
