PCI Express to Serial Port Card
460.8 Kbps Data Transfer Rate

The PEX2S553 PCI Express serial card lets you turn a PCI Express slot into 2 RS232 (DB9) serial ports. Based on a native single chip design (no bridge chip), this 2-port serial adapter card allows you to harness the full capability offered by PCI Express (PCIe), and reducing the load applied to the CPU by as much as 48% over conventional serial cards.

The RS232 Serial Adapter Card (PEX2S553) 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 MAC OS 10.4 and above.

Plus, the serial card includes an optional half-height/low profile bracket that allows the card to be installed in any PCI Express slot, regardless of the size of the computer case.

Add Two Serial Ports to Your PC Based on the native single-chip, single lane PCI Express chipset, the StarTech PEX2S553 card adds two RS232 (DB9) Serial ports to any PCIe equipped computer for easy connection to serial devices.
Low Profile Bracket Included Standard and low profile/half-height brackets are included to ensure fitment in any system.

drandrae 8/30/2011 12:01:09 PM Tech Level: 4/5 Ownership: 3/5 Verified Owner	Rating: 3/5Infant Mortality Pros: I am giving this three eggs because this card was easy to install, supported by older and current OSs and their technical support was surprisingly easy to access and helpful - confirm using the latest driver, re-seat the card, try a different PCI-e slot/computer, get another card. Cons: I am not giving it five eggs because it only worked for two days before starting to fail - it would drift in and out of being recognized by Windows XP and eventually was unresponsive after about a week. Other Thoughts: Now it is up to Newegg's RMA process to get a replacement and see how it performs. 1 out of 1 people found this review helpful. Did you?
