Introduction
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 slot.
Based on a native single chip design, this 4-port serial adapter card allows you to
harness the full capability oered by PCI Express (PCIe), and 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 prole brackets allowing the
card to be installed into almost any PC case, regardless of form factor.
