The PX1-4S-9904 4-Port Native PCI Express RS232 Serial Adapter Card with 16C550 UART lets you add 4 RS232 (DB9) serial ports, using a single PCI Express expansion slot.

Based on a native single-chip design, this 4-port serial adapter card allows you to 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 RS232 Serial Adapter Card includes 2 half-height/low-profile brackets, allowing the card to be installed into almost any PC case, regardless of form factor.
