1-Port PCI Express Serial Card with RS232 DB9 Interface, 16C1050 UART, 256-Byte FIFO, Low-Profile Bracket, and COM Retention for Desktop and SFF Systems
The StarTech 11050-PC-SERIAL-CARD is a PCI Express serial card that adds one RS232 (DB9) serial port to any desktop or small form factor system through a PCIe x1 slot, providing reliable serial communication for POS terminals, industrial controllers, security systems, and legacy peripherals at speeds up to 921.6 Kbps. The card features a 16C1050 UART with 256-byte transmit/receive FIFO for high-throughput serial data handling, and COM port retention preserves port assignments across reboots for consistent device addressing. A 1-port PCIe serial card from StarTech with low-profile bracket included, serial port LED status lights, Windows and Linux support, and a 2-year warranty.
The included low-profile bracket enables installation in small form factor and slim desktop cases alongside the standard full-height bracket, and plug-and-play driver support across Windows and Linux eliminates manual configuration for immediate deployment in production environments.
Where the 11050-PC-SERIAL-CARD Fits
- Retail and POS environments where the RS232 serial port connects receipt printers, barcode scanners, cash drawers, and payment terminals that rely on serial communication for transaction processing
- Industrial and manufacturing systems where the 16C1050 UART with 256-byte FIFO handles high-throughput serial data from PLCs, CNC controllers, measurement instruments, and automation equipment at speeds up to 921.6 Kbps
- IT infrastructure upgrades where COM port retention preserves serial port assignments across system reboots, maintaining consistent device addressing for managed switches, UPS units, and out-of-band management consoles
What the 11050-PC-SERIAL-CARD Delivers
- 1 RS232 serial port via PCIe x1: DB9 connector with bi-directional communication at speeds up to 921.6 Kbps. PCIe x1 interface provides dedicated bandwidth without sharing the legacy PCI bus.
- 16C1050 UART with 256-byte FIFO: Hardware UART with deep transmit and receive buffers reduces CPU overhead and prevents data loss during high-speed serial communication with industrial and POS peripherals.
- COM retention and LED status lights: COM port numbering persists across reboots for consistent device addressing. Front-panel LED indicators show serial port activity for quick connection verification.
- Dual-profile with Windows and Linux support: Full-height and low-profile brackets included for standard desktop and SFF installations. Plug-and-play driver support on Windows and Linux for immediate deployment.
