        • Add 2 high-speed RS-232 serial ports to your low profile/small form factor computer with a PCI Express expansion slot

          The PEX2S553LP low profile/half-height PCI Express Serial Card turns a PCI Express slot into two RS232 (DB9) serial connections.

          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®; and 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 2 serial ports to virtually any computer (regardless of the case form factor).

          This product is a replacement for our PEX2S552LP card.

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