In an era where everything is USB-C, the PI40952-3X2B is a reminder that serial ports (COM ports) still run the world's infrastructure. Whether you're connecting a POS system, a protocol converter, or an IoT device, this card provides a native PCI Express x1
connection that is far more stable than cheap USB-to-Serial adapters.
: It’s not flashy, but it is essential. If your hardware needs an RS-232 port, the PI40952-3X2B from DeLOCK is a robust, "set it and forget it" solution. Do you need help locating the specific drivers for a particular operating system version? Delock PCI Express Card to 2 x Serial
Description. The PCI Express card by Delock expands a PC by two external serial ports. Different devices such as scanner, printer, Delock PCI Express Card to 1 x Parallel IEEE1284
PI40952-3X2B is a versatile PCI-Express adapter card, most commonly found as a dual RS232 serial port
expansion, though some variants offer a parallel (LPT) port instead. It is typically branded by manufacturers like Product Specifications Interface: PCI Express x1 (V1.1 compatible). Serial Variant: 2 x RS232 (DB-9) male ports. Parallel Variant: 1 x Parallel (DB-25) female port. Often powered by the Oxford OXPCIe952 Form Factor: PI40952-3X2B is a specialized PCI Express adapter card
Low-profile design, making it compatible with mini-PCs and small form factor (SFF) desktops. Data Rates: Supports serial speeds up to 230.4 Kbps (Oxford) or 460.8 Kbps Performance Review Reliability:
Users and sellers frequently note its functionality in legacy industrial environments for connecting scanners, printers, or laboratory equipment. Compatibility:
The card is widely compatible with Windows 7 through Windows 11, as well as Linux kernels which often have native support for these chipsets. Ease of Use:
While often sold "as-is" without a driver CD in the used market, drivers are generally available via the manufacturer's website or third-party repositories. Driver Information
If you are looking for the driver, it is critical to identify the specific chipset on your card (usually the largest black square chip): Oxford Chipset: Drivers can be found on the Delock Support Page for similar models. WCH Chipset: Drivers are often hosted by TITAN Electronics for universal PCI-E serial cards. Automatic Detection:
Most modern Windows versions (10/11) may automatically detect and install the driver through Windows Update once the card is seated. Shopping Options Scenario: LED matrix controlled by pi40952 3x2b driver
This card is primarily available through electronics refurbishers and second-hand marketplaces: Refurbished Units: Available at retailers like D-Stock Micro Used Listings: Frequently listed on for prices ranging from approximately $15.00 to $55.00 USD depending on the seller and condition. exact chipset version for your specific OS installation? Delock PCI Express Card to 2 x Serial
Based on the hardware identifier pi40952, this refers to the Azurewave Realtek RTL8852BE Wi-Fi 6 Bluetooth 5.2 combo module. This card is commonly found in HP laptops (such as the HP Pavilion and HP 15 series).
The 3x2b part of your string is likely a fragment from the hardware ID (PCI\VEN_10EC&DEV_3x2B) or a component of the device path.
Here is the breakdown of the driver you need and how to install it.
14. Case Study (Hypothetical)
- Scenario: LED matrix controlled by pi40952 3x2b driver.
- Use batch writes to update rows atomically.
- Configure channels as push-pull with adjustable drive strength.
- Use PWM-capable output mode if supported for dimming.
- Add rate-limiter in software to avoid over-temperature on sustained high brightness.
How to Install the Drivers
Because Windows Update often struggles to find the correct driver for this specific Realtek card, it is best to download it manually.
12. Example Implementation Notes
- For Linux: use regmap for MMIO or SPI/I2C convenience, implement platform_driver probe/remove, support dev_pm_ops, and provide sysfs attributes for channels.
- For RTOS/bare-metal: modularize transport and use function pointers for hardware abstraction; keep ISR fast and delegate processing to tasks/threads.
2. Device Overview (Hypothetical)
- Part Number: PI40952
- Function: 3-channel, 2-bit parallel driver
- Package: [e.g., SOIC-16, TSSOP-20]
- Logic Family: [e.g., LVCMOS, TTL]
- Output Type: [e.g., push-pull, open-drain, tri-state]
2. Automated Test Equipment (ATE)
- Why: Controlling three independent solenoids or pneumatic valves in a test fixture.
- Benefit: Binary states (off, low, medium, high flow) allow granularity without complex DACs.
Likely Architecture
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).
Option 1: Official HP Support (Recommended)
This card is an OEM part for HP. The most stable driver comes from the HP support page.
- Go to the HP Customer Support - Software and Driver Downloads page.
- Enter your laptop's serial number or model number (e.g., HP 15-dyxxxx).
- Look for the Network or Driver-Network section.
- Download the driver named Realtek RTL8852BE Wi-Fi 6 or Bluetooth Driver.
Direct Link Search:
If you prefer to search manually, search for the driver file usually named something like:
sp142198.exe (This is a common HP package for this card) or sp137299.exe.
