Introduction
The PEX4S952 4 Port Native PCI Express RS232 Serial Adapter Card with 16950 UART allows you
to turn a PCI Express slot into 4 RS-232 (DB9) serial connections.
The four port serial card is based on a native single chip design, that harnesses the full capability
of PCI Express (PCIe) - providing optimum reliability and speed, and reducing the load applied to
the CPU by as much as 48% over conventional serial cards.
Oering compatibility with a broad range of operating systems including Windows®, Linux and
Mac® OS for easy integration into mixed environments. Plus, an included optional low prole/
half-height bracket that allows the card to be installed in virtually any computer case – making
it that much easier to add serial ports to your PCI Express enabled computer, regardless of the
case form factor.
