PEX4S952LP PCI Express Card

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).

Backed by a Lifetime warranty and free lifetime technical support.
