8-Port PCIe RS-232 Serial Adapter

The StarTech PEX8S1050 adds eight DB9 serial ports to a desktop through a single PCI Express slot. It targets technicians and system integrators who must connect legacy RS-232 equipment such as industrial controllers, PIN pads, or modems to modern platforms.

Low-profile bracket with 8-port breakout cable

A compact bracket fits standard and low-profile chassis while the included breakout cable routes eight DB9 connectors to accessible locations. Each port supports speeds up to 921.4Kbps, and broad Windows and Linux support simplifies driver deployment in mixed environments.

Replaces multi-card serial expansions

One card consolidates what previously required multiple single or dual-port adapters, freeing expansion slots and reducing cabling clutter. The jump is worthwhile when a workstation or server must drive several serial devices simultaneously without occupying additional PCIe lanes.
