1 Port Low Profile Native RS232 PCI Express Serial Card with 16550 UART

StarTech ID: PEX1S553LP

The PEX1S553LP PCI Express Serial Card turns a PCI Express slot into an RS232 (DB9) serial connection.

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™/Windows 7/Server 2008 R2 (32 and 64 bit), Linux Kernel 2.6.11 and up, and
ships with a low profile/half-height bracket installed, but includes an optional full profile bracket that lets you add
a serial port to virtually any computer (regardless of the case form factor).

This product is a replacement for our PEX1S552LP card.
