StarTech PCIe Card with Serial and Parallel Port, PCI Express Combo Expansion Adapter Card, 1x DB25 Parallel & 1x RS232 Serial, TAA

Upgrade your computer's connectivity with the StarTech.com PEX1S1P950 PCIe expansion card, designed to add both a DB25 parallel port and a DB9 serial port using a single PCI-Express x1 slot. This versatile card is ideal for connecting legacy printers, scanners, plotters, and scientific or medical equipment that rely on parallel and serial interfaces. The installation process is straightforward, with compatibility across a wide range of systems including Windows 7 and newer, Windows Server 2003 and higher, as well as Linux distributions starting from kernel 2.6.X. The card fits into standard PCIe x1 slots, providing a seamless upgrade for desktop and industrial computers alike.

The parallel port supports data transfer speeds up to 2.5 Mbps and is compatible with SPP, Byte, Nibble, and ECP modes, conforming to IEEE 1284 standards. This allows reliable communication with devices such as point-of-sale terminals, industrial PLCs, and scientific sensors. The serial port features bi-directional RS232 communication with speeds up to 921.6 Kbps, supported by a 256-byte FIFO buffer and an industry-standard 16C950 UART controller. An optional SATA power input enables enhanced power management by adjusting voltage output between 5V and 12V, which can be set via a jumper on the PCB.

Designed for broad application, this combo card supports automation, control, and data acquisition tasks in manufacturing, healthcare, and research environments. It features auto IRQ and IO address assignment, PCI Power Management 1.2 compliance, and supports IRQ sharing for optimal resource allocation. Backed by a lifetime warranty and supported by StarTech.com’s dedicated technical team, this expansion card ensures long-term reliability and professional-grade performance. Whether upgrading an existing system or building a new setup, the PEX1S1P950 provides a cost-effective solution for expanding legacy device compatibility with modern computers.
