Pi40952 3x2b Driver _best_ Jun 2026

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.

: Drivers typically support Windows 7, 8.1, and 10 (both 32-bit and 64-bit).

Download the CH38XDRV installation package from Nanjing Qinheng Microelectronics. This package supports Windows 11/10/8.1 and Linux. 3. Installation Guide

Locate an empty PCIe slot (usually a short × 1 slot, though a × 4 or × 16 will also work). pi40952 3x2b driver

This is often the most user-friendly method for those who prefer a hands-off approach.

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.

Right-click the item and choose , then navigate to the Details tab. Because these devices are often engineered for long

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.

Most versions of this hardware utilize the Oxford (PLX/Broadcom) or MCS (MosChip) serial/parallel controller chipsets, such as the OX16PCI952. 2. Driver Specifications

PI40952-3X2B is a PCI Express expansion card designed to add two RS-232 serial ports (DB9) and typically one parallel port This package supports Windows 11/10/8
