Product Description


Add 4 high-speed RS-232 serial ports to your PC through a low profile PCI Express expansion slot. The PEX4S952LP 4 Port Low Profile Native RS232 PCI Express Serial Card (16950 UART) turns a PCI Express slot into four RS232 (DB9) serial connections.

The card is constructed using a native single chip design that lets you harness the full capability offered by PCI Express (PCIe), while reducing the load applied to the CPU by as much as 48% over conventional bridge chip serial cards.

The PCI Express RS232 Serial Adapter Card is compatible with a broad range of operating systems, including Windows 2000/XP/2003/Vista, Linux Kernel 2.6.11 and up, and ships with a half-height/low profile bracket installed, but also includes an optional full profile bracket that lets you add four serial ports to virtually any computer (regardless of the case form factor).
