If you give me that, I can track down the exact datasheet and write up the complete post (pinout, application circuit, voltage range, control logic).

PI40952-3X2B is a specialized PCI Express adapter card manufactured by

that adds two external serial RS-232 ports to a PC. Often used to breathe life into legacy hardware, this card is a "quiet achiever" in the world of industrial and niche computing. The "Legacy Lifeline" Review

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

form factor, making it a perfect fit for Mini-PCs and slim workstations. The Brains : Powered by an Oxford chipset , it handles data transfer rates up to 230.4 Kbps pi40952 3x2b driver

. While that sounds slow by modern fiber-optic standards, it's the "speed of light" for the RS-232 devices it’s meant to control. Driver Compatibility

: DeLOCK has kept this card relevant with broad driver support. It’s verified for everything from older Windows versions to Windows 11 Performance 128-byte FIFO

buffer and compatibility with 16C950 UART, it ensures that data streams remain steady and don't "drop" when your legacy equipment is doing heavy lifting. Why It’s Interesting

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 Common typos / near-matches:

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

Previous versions suffered from ground bounce during high-current switching events. The 3x2B revision addresses this by:

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:

    • In the world of precision motion control and industrial automation, the driver IC is the silent workhorse that translates low-voltage logic into high-current actuation. Among the myriad of part numbers that populate datasheets and BOMs (Bills of Materials), the PI40952 3x2B driver stands out as a specialized, albeit often misunderstood, component.

    If you have landed on this article, you are likely searching for technical documentation, pinout configurations, or programming insights for the "PI40952 3x2B." Whether you are repairing a legacy CNC machine, designing a custom PCB for a multi-axis robot, or reverse-engineering a proprietary board, this guide will provide the comprehensive details you need.

    Note: The identifier "3x2B" typically refers to the driver's output topology—often interpreted as three half-bridges (3x) with two binary inputs (2B) or a 3-channel, 2-bit logic interface. We will decode this fully below. Can you provide:

    The board features a standard 2.54mm pitch header layout for easy integration into breadboards or perf-board projects.

    Before diving into pinouts, let’s break down what the keyword implies.

    If you cannot source the exact PI40952 3x2B driver (due to obsolescence or regional shortages), consider these drop-in or functional equivalents:

    | Part Number | Channels | Control Type | Voltage | Current | Compatibility | |-------------|----------|--------------|---------|---------|----------------| | DRV8412 | 2 | 2x2B | 50V | 6A | Needs external logic for 3rd channel | | L6206 | 2 | 2x2B | 52V | 5.6A | Dual channel only | | TB6612FNG | 2 | 2x2B | 15V | 3.2A | Low voltage, not a direct replacement | | BD6231 | 1 | 2B | 32V | 3A | Use three ICs for 3 channels | | MC33887 | 1 | 2B | 40V | 5A | Robust, but single channel only |

    For a proper 3-channel replacement, two DRV8412s or three MC33887s would be required. The PI40952 remains unique in its 3x2B monolithic integration.
