2-Port PCIe RS-232 DB9 Serial Port Card – Windows XP/7/8/10/11 & Linux Compatible (32/64bit) for Fast Data Transfer (PCIe1X Dual Serial Card)

Description

Product Overview

The BZIZU 2‑Port PCIe RS‑232 DB9 Serial Card is engineered to expand the connectivity of modern desktop and industrial computers. Housed in a compact 2.57 × 0.63 × 2.36 inch metal enclosure, the card weighs just 3.2 ounces, making it unobtrusive while delivering robust performance. Powered by the ASIX AX99100 controller, the card supports a 256‑byte deep FIFO buffer, ensuring smooth, loss‑less data flow even under heavy traffic. The dual DB9 connectors are fully compliant with the RS‑232 standard, providing reliable communication with legacy equipment such as point‑of‑sale terminals, barcode scanners, industrial control panels, and serial printers.

Designed for universal compatibility, the card works seamlessly with Windows XP, Vista, 7, 8, 10, 11 (both 32‑ and 64‑bit) and a wide range of Linux kernel versions from 2.6.x through 5.x. The driver package, delivered on a Mini‑CD, includes installers for Intel, AMD, and ARM platforms, guaranteeing plug‑and‑play operation across diverse hardware ecosystems. Whether you are upgrading a legacy system or building a new industrial workstation, this card provides a cost‑effective solution for adding high‑quality serial interfaces.

Usage

In retail environments, the BZIZU serial card enables seamless integration of POS cash registers, receipt printers, and barcode scanners that rely on RS‑232 communication. Manufacturing floors benefit from the card’s ability to connect PLCs, CNC machines, and diagnostic tools without the need for external adapters. Security installations can link legacy alarm panels and access control readers directly to a central monitoring PC, simplifying cabling and reducing latency.

Because the card occupies a standard PCIe ×1 slot, it can be installed in full‑size desktop towers as well as compact workstations. For slim cases, the included low‑profile brackets replace the full‑size bracket, ensuring a clean fit without obstructing other components. The card’s hot‑swap capability allows technicians to replace or add the card without powering down the system, minimizing downtime in mission‑critical applications.

Engineers developing embedded Linux solutions appreciate the straightforward driver installation process, which supports kernel versions from 2.6 to 5.x. The card’s low power consumption and stable signal integrity make it suitable for long‑run data logging, remote sensor networks, and automated testing rigs where reliable serial communication is paramount.
