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.

Instruction Manual 3
Setting Power Mode
This card is specially designed to allow for power output from the ninth pin of the DB9
connector(s) for devices that support power over serial. This card allows users to set each port
with 5V, 12V, or RI (no power). Users can also choose to draw the necessary power from the
system power supply by connecting to the LP4 power connector.
Hardware Installation
1. Remove the cover of your system (see your computer’s user manual for details, if necessary)
and gently turn your computer onto its side, so that the PCI Express expansion slot openings
on the motherboard are facing upwards.
2. Locate an empty PCI Express slot and remove the metal plate that covers the corresponding
rear bracket. You may need a Phillips screw driver to perform this step. Retain any screws! You
will need them to secure the card later. Refer to documentation of your computer system for
further details.
PEX2S5531P Only: Please ensure that the metal plate that covers the rear bracket adjacent
to the above mentioned bracket is vacant, so that it can be used for the parallel port
installation).
3. Gently insert the card into the empty slot, making sure it is rmly seated, then secure the card
in place using the screw you removed in Step 3, if applicable.
4. PEX2S5531P: Connect the ribbon cable provided by the (separate) parallel port to the
provided slot on the PEX2S5531P board (please see diagram on previous page), then secure
the parallel port to the slot adjacent to the one used to secure the main PEX2S5531P board.
5. OPTIONAL: If supplying power from the computer system power supply, (see “Setting Power
Mode”) connect the LP4 molex plug into the card.
6. Once the card (and additional port, if necessary) are secured to the motherboard (and within
the case), replace the computer cover and power on the computer, then proceed to the next
section, titled Software Installation.
