Marketing blurb (brief):
The is an expansion card used to add legacy ports to modern computers through a standard PCI Express (PCIe) slot. Sold under various brand labels including Exone , Espircom , and Manhattan , this hardware adapter is typically configured either as a dual serial port card or an LPT/parallel printer port expansion adapter.
: Comes with low-profile brackets, making it suitable for standard PCs and Mini-PCs alike. Reliable Performance
: 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 pi40952 3x2b driver
Before diving into pinouts, let’s break down what the keyword implies.
Design note: prefer batch writes with bitmasking to reduce bus operations; provide atomic update functions to avoid transient invalid states.
If connected peripherals drop data packets during industrial data logging, access the device properties via Device Manager. Open Port Settings , select Advanced , and reduce the FIFO Transmit/Receive Buffers from maximum limits down to safer median thresholds. Marketing blurb (brief): The is an expansion card
The driver ecosystem for the core powering the PI40952-3X2B is highly flexible, supporting classic server platforms as well as modern 64-bit desktop environments: Delock PCI Express Card to 2 x Serial
The "3x2B" revision represents the third major iteration of the layout, optimized for a 2-layer PCB design with improved thermal relief.
Finding an official datasheet for the PI40952 can be challenging. Based on cross-referencing with similar drivers (e.g., TI DRV8432, ST L6206), we can derive a for the PI40952 3x2B. Reliable Performance : Windows 10 and 11 often
: Most variants utilize an Oxford (Plx/Broadcom) or a WCH (Nanjing Qinheng Microelectronics) PCIe-to-UART/Parallel bridge chip (such as the CH382 or OXPCIe952 series).
If the card is listed as an or "PCI Serial Port" in Windows Device Manager: Right-click the device and select Properties . Go to the Details tab and select Hardware IDs . Look for the Vendor ID ( VEN ) and Device ID ( DEV ). VEN_1415 : This is an Oxford/PLX chip. VEN_1C00 : This is a WCH chip.
