The PEX4S553 4-Port Native PCI Express RS232 Serial Adapter Card with 16550 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 4 half-height/low-profile brackets, allowing the Card to be installed into almost any PC case, regardless of form factor.
