Add a RS-232 serial port to your standard or small form factor computer through a PCI Express expansion slotThe PEX1S553LP PCI Express Serial Card turns a PCI Express slot into an RS232 (DB9) serial connection.

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 4.11. x, 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. Backed by a StarTech. com 2-year warranty and free lifetime technical support.
