PI40952-3X2B is a PCI Express expansion card designed to add two RS-232 serial ports (DB9) and typically one parallel port (DB25) to a PC. It is commonly associated with manufacturers like Driver Identification & Downloads Because this card is often rebranded, the driver you need depends on the used on the physical board. Most versions of the PI40952-3X2B use one of the following: Oxford Chipset : Common in Delock-branded models (e.g., Delock Item 89220 ). Drivers for Windows 7 through 10 are available on the Delock Service Page WCH Chipset (CH382L/CH384) : Frequent in newer or generic versions. You can find official drivers on the WCH (Nanjing Qinheng) Download Center Moschip (MCS9901/9922) : Used in cards providing both serial and parallel functionality.

user wants a long article about "pi40952 3x2b driver". I need to gather comprehensive information to write an article. I will start by searching for various aspects of this keyword. search results show some references to "pi40952 3x2b driver" related to a PCI-Express card and possibly a Raspberry Pi device. There are also some irrelevant results. I need to open the relevant ones to gather more details. search results have provided some information about the "pi40952 3x2b driver". The NPM package page and a blog post mention it in the context of Raspberry Pi. There's also a French website listing a product "PI40952-3X2B" as a PCI-Express adapter card. These seem to be related but possibly different things. The user might be looking for information on a specific driver. I need to structure an article that covers the possible interpretations: a PCI-Express serial card, a driver for Raspberry Pi, or possibly a misidentified component. I will also search for more details on the PCI-Express card and the Raspberry Pi driver. search results show that "PI40952-3X2B" is a PCI-Express to 2-port RS232 serial adapter card. The "pi40952 3x2b driver" might refer to drivers for this card or for a Raspberry Pi device. There's also an NPM package that seems to be a driver utility. The user likely wants a comprehensive article covering all these aspects. I will structure the article to include an introduction, description of the hardware (PCIe serial card), driver installation for Windows and Linux, troubleshooting, and safety tips. I will also address the confusion with Raspberry Pi-related references. Now I will write the article.ofiem Electronics also has the card listed, describing it as "CARTE ADAPTATEUR PCI-EXPRESS 2 PORTS RS232 9-PIN DELOCK PI40952-3X2B LOW PROFILE". This shows its function is to add two 9-pin RS232 serial ports to a desktop PC via a PCI-Express slot. 📑 Understanding the "Pi40952 3x2b" Name The name "PI40952-3X2B" likely represents a specific product model for a legacy PCIe serial card from brands like Delock (note the description includes 'DELOCK'). The "3x2b" part does not refer to a standard technical specification like a "3-phase, 2-bridge" driver but is part of this unique product identifier. 🔌 The Core Hardware: A PCIe-to-Serial Card The PI40952-3X2B is a low-profile PCI-Express adapter card. Its job is to convert a PCIe slot inside a computer into two standard RS232 COM ports. These older 9-pin serial ports are still crucial in many professional and industrial settings for connecting:
Industrial Equipment: CNC machines, PLCs, and other legacy industrial automation hardware. Network Infrastructure: Managed switches, routers, and UPS devices. Point-of-Sale (POS) Systems: Cash registers, barcode scanners, and receipt printers. Scientific Instruments: Laboratory scales, analyzers, and measurement devices.
Because these devices are often engineered for long life cycles, a modern computer may lack native serial ports, making the PI40952-3X2B a vital tool. 🛠️ Step-by-Step: How to Install Drivers for Your PI40952-3X2B Finding and installing the correct driver is key to getting the card to work. The exact process will vary slightly between Windows and Linux. Here are your options. Option 1: Installing Drivers for Windows (XP to 11) Most modern Windows versions have built-in drivers for standard serial port controllers. pi40952 3x2b driver
Automatic Installation:
Power off your PC, install the PI40952-3X2B card into an available PCI-Express slot, and power on. On newer Windows versions, the OS should automatically detect the new hardware and attempt to install a generic driver.
Using Device Manager (If the card isn't working): PI40952-3X2B is a PCI Express expansion card designed
If the card isn't working, open Device Manager . (Press Windows + X and select "Device Manager"). Look for the Pi40952 3x2b Device, which might be listed under "Other devices" with a yellow exclamation mark. This indicates the driver is missing or incorrect. Right-click on the device and select "Update driver" . Choose "Search automatically for drivers" .
Manually Install via Hardware ID:
If the automatic search fails, you can find drivers using the device's Hardware ID . In Device Manager, right-click the device > Properties > Details tab. Under Property , select Hardware Ids . Right-click and copy the first value (e.g., PCI\VEN_xxxx&DEV_xxxx ). Search the web for this Hardware ID, which can often lead you to the correct driver packages. Drivers for Windows 7 through 10 are available
Option 2: Installation on Linux / Raspberry Pi If you are using this card with a Linux system (such as a Raspberry Pi running a full desktop OS like Ubuntu), the setup is often even simpler.
Many Linux distributions have built-in support for a wide range of serial hardware. The system will likely auto-detect the card when it's connected. The drivers are often already present in the kernel. The NPM package 04qox_odx mentions installing drivers for a "Raspberry Pi device", but this is distinct from the PI40952 card itself. It's more likely a utility to help configure a Pi to act as a USB device. The PCIe card, on the other hand, would only be compatible with a standard x86-based computer, not a Raspberry Pi.
