StarTech - PEX4S552 - 4 Port Native PCI Express RS232 Serial Adapter Card with 16550 UART

The PEX4S552 4-port PCI Express-based serial adapter card lets you turn a PCI Express slot into 4 RS-232 (DB9) serial connections.

The adapter card is based on a native single chip design, that allows you to harness the full capability of PCI Express (PCIe) - providing optimum reliability and speed while reducing the load applied to the CPU by as much as 48% over conventional serial cards.

The RS-232 Serial Adapter Card is compatible with a broad range of operating systems, including Windows® 2000/XP/2003/Vista/Windows 7/Server 2008 R2 (32 and 64 bit), Linux Kernel 2.6.11 and up, as well as MAC® OS 10.4 and above.

To ensure broad compatibility, the 4 port PCIe Serial Adapter card includes an optional low profile/half-height bracket that allows the card to be installed in virtually any computer case â?" making it easier to add serial ports to a PCI Express enabled computer, regardless of the size of the computer case.
