StarTech PEX8S1050 – 8-Port PCI Express RS232 Serial Card with 161050 UART

Overview :

The StarTech PEX8S1050 is a high-density, professional-grade serial expansion card designed to provide stable, legacy connectivity for modern computer systems. It is utilized by industrial engineers, IT administrators, and retail system integrators who need to interface multiple RS232 peripherals—such as barcode scanners, receipt printers, PLCs, and satellite receivers—with a single server or workstation.

Technically, the card is built around the high-performance Systembase 16C1050 UART, which features an expansive 256-byte FIFO (First In, First Out) buffer. This larger buffer significantly reduces the CPU overhead and prevents data loss during high-speed transmissions compared to standard 16C550 UARTs. The card supports data transfer rates up to 921.6Kbps and features native single-chip architecture, ensuring maximum compatibility and reliability by reducing the complexity of the PCIe-to-Serial bridge.

Deployment is simplified in high-density environments through the use of an included VHDCI 68-port to 8x DB9 breakout cable, which prevents port crowding at the back of the PC. The card features a universal design that includes both full-profile and low-profile brackets, making it compatible with standard towers and small-form-factor (SFF) systems. It is optimized for continuous operation but should be installed in a PCIe x1 slot or larger (x4, x8, or x16).

Key Features :

• High-performance 16C1050 UART with 256-byte FIFO for reduced CPU load.
