StarTech PEX8S1050LP – 8-Port Low-Profile PCI Express RS232 Serial Card with 161050 UART

Overview :

The StarTech PEX8S1050LP is a specialized high-density serial expansion card designed specifically for small-form-factor (SFF) systems. It is utilized by industrial automation specialists, IT technicians, and POS system integrators who need to add extensive RS232 connectivity to compact servers or workstations where internal space is at a premium.

Technically, the card is identical in performance to the standard-profile PEX8S1050, featuring the high-performance Systembase 16C1050 UART. This controller includes a 256-byte FIFO buffer, which manages high-speed data more efficiently than standard 16-byte buffers, significantly lowering CPU utilization during multi-port transmissions. The card supports baud rates up to 921.6Kbps and uses a native single-chip design to improve speed and reliability by eliminating the overhead of bridge chips.

Deployment is tailored for slimline chassis, as the card comes with a low-profile bracket pre-installed. It utilizes a high-density VHDCI 68-pin connector and includes a breakout cable that provides eight individual DB9 male ports. This allows for a clean, single-slot installation that can support an entire array of serial peripherals—from CNC machinery and scientific sensors to receipt printers—without requiring a full-sized desktop tower.

Key Features :

• Low-profile bracket pre-installed for small-form-factor (SFF) computer cases.

• High-performance 16C1050 UART with 256-byte FIFO for efficient data handling.

• VHDCI 68-pin to 8-port DB9 breakout cable simplifies cable management.

• Supports high-speed RS232 data transfer rates up to 921.6Kbps.

• Native single-chip PCI Express x1 architecture ensures low latency and high stability.
