Product Overview
The StarTech PEX2S952LP is a professional-grade, 2-port native PCI Express RS232 serial adapter card. Unlike conventional cards that use a bridge chip, this unit features a native single-chip design (Oxford OXPCIe952). This significantly increases reliability and speed while reducing CPU load by up to 48%. Engineered for high-performance and low-latency communication, it is the industry standard for connecting legacy serial peripherals to modern PCIe-enabled systems.
Key Features
Native Single-Chip Design: Harnesses the full capability of PCI Express for optimum performance.
Dual DB9 RS232 Ports: Provides two independent serial connections with data transfer rates up to 460.8 Kbps.
16950 UART Compatibility: Features 128-byte deep FIFO per transmitter and receiver for high-speed data handling.
Selectable Power Output: Pin 9 can be configured for 5V or 12V power output to drive connected devices without external adapters.
Broad OS Support: Fully compatible with Windows (XP to 11), Windows Server, and Linux.
Why Choose This Server?
In a server or industrial environment, the PEX2S952LP is prized for its low-profile footprint and efficiency. It allows you to maintain legacy infrastructure—such as console ports, CNC machinery, or POS equipment—within modern, high-density rack servers or SFF (Small Form Factor) desktops without sacrificing system stability or performance.
Why Buy This Config?
The PEX2S952LP is pre-configured with a low-profile mounting bracket, making it "plug-and-play" for slimline servers and workstations. The native Oxford chipset ensures that drivers remain stable across operating systems, preventing the "blue screens" often associated with cheaper, non-native serial cards.
Compatibility & Use Cases
HomeLab: Dedicated serial console access for managing enterprise switches and routers.
POS & Retail: Controlling receipt printers, barcode scanners, and cash drawers.
Industrial Automation: Reliable communication for PLCs, CNC machines, and scientific sensors.
Enterprise Management: Adding out-of-band management capabilities to headless servers.
Condition
Cleaned, working environment pull, minor cosmetic scrapes.
Removed from a working environment. Minor surface scuffs on the bracket may be present, which do not affect functionality.

FAQs
Does this support Windows 11? Yes, this card uses the native Oxford chipset which is supported by standard serial drivers in Windows 10 and 11.
Can I use this in a full-size PC? This listing is for the Low Profile version. While the card fits a full-size PCIe slot, you would need a standard-height bracket (not included) to secure it.
How do I configure the power output on Pin 9? This is set via onboard jumpers. Please refer to the manufacturer's manual for specific voltage settings.
