StarTech.com 1 Port Native PCI Express RS232 Serial Adapter Card with 16550 UART

Add a high-speed RS-232 Serial port to your computer through a PCI Express expansion slot

The PEX1S553 PCI Express Serial adapter card allows you to turn 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 to 4.11x, as well as MAC OS X 10.4 and above. The adapter card includes an optional half-height/low 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 PEX1S552 card.
