Introduction
The PEX2S952PW 2 Port PCI Express RS232 Serial Adapter Card with Power Output
turns a PCI Express slot into 2 RS-232 (DB9) serial connections and the ports provide
power output to your devices.
Suitable for many RS232 powered serial applications, and including both low and full
prole brackets, the selectable 5V or 12V power option is able to output using pin 1,
4, 8 or 9, allowing you to congure the card to suit the requirements of your powered
RS232 devices.
The PCI express serial card is based on a native single chip design, that allows you
to harness the full capability of PCI Express (PCIe) - providing optimum reliability
and speed while reducing the load applied to the CPU by as much as 48% over
conventional (bridge chip) serial cards.

Installation
WARNING! PCI Express cards, like all computer equipment, can be severely
damaged by static electricity. Be sure that you are properly grounded before
opening your computer case or touching your PCI Express card. StarTech.com
recommends that you wear an anti-static strap when installing any computer
component. If an anti-static strap is unavailable, discharge yourself of any
static electricity build-up by touching a large grounded metal surface (such
as the computer case) for several seconds. Also be careful to handle the PCI
Express card by its edges and not the gold connectors.

system for details.
3. Locate an open PCI Express slot and remove the metal cover plate on the rear of the
computer case (Refer to documentation for your computer system for details.). Note
that this card will work in PCI Express slots of additional lanes (i.e. x4, x8 or x16 slots).
4. Gently insert the card into the open PCI Express slot and fasten the bracket to the
rear of the case.
NOTE: If installing the card into a small form factor/low prole system, replacing the
pre-installed full prole bracket with the included low prole installation bracket may
be necessary.
