PCI Express x1 (compatible with x4, x8, and x16 slots).
The identifier PI40952-3X2B designates the physical layout layout of the PCB board. Depending on the production run, the board configuration relies on two distinct main chipsets. Identifying your exact chipset determines which operational driver download package your system needs: Delock PCI Express Card to 2 x Serial
Once you have identified the chipset or sourced the appropriate installation package, follow these sequential steps to install the driver:
If automatic methods fail, you can manually install the generic PLX/Oxford drivers:
Remove the corresponding metal cover from the back of your PC case.
: For hobbyists working with microcontrollers, a dedicated PCIe serial card often offers lower latency and better stability than cheap USB-to-serial adapters.
The is a widely integrated printed circuit board (PCB) assembly used across various legacy expansion cards. Most notably, it powers Delock PCI Express I/O Cards and STLab I-360 adapter cards , which bridge modern desktops with legacy infrastructure by adding dedicated serial (RS-232 DB9) or parallel (LPT DB25) printer ports.

Often serves as a Dual Serial (RS-232) Port Adapter or a Parallel (LPT) Port Adapter .
