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® and Linux Kernel 2.6.11 to 4.11.x 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.

This product is a replacement for our PEX2S552 card.
