Installation
WARNING!
PCI Express Serial Cards can be severely damaged by static electricity. Make sure
that you are properly grounded before you open your Computer Case or touch the
PCI Express Serial Card. You should wear an Anti-Static Strap when you install any
computer component. If an Anti-Static Strap isn’t available, discharge any built-up
static electricity by touching a large Grounded Metal Surface for several seconds. Only
handle the PCI Express Serial Card by its edges and don’t touch the gold connectors.
Jumper Conguration
Note: Jumper conguration is a requirement when connecting Serial Devices that
require power through a Serial Port.
This Jumper can be moved into one of three dierent positions in order to set the
power output voltage for the Serial Ports. The default setting for the Jumpers is RI,
which is the setting for no power. The Jumper can be moved to one of the other two
settings for 5V or 12V of power. To congure the Jumper, complete the following:
1. Locate the Jumper for Port One. Port One is located on the right hand side, labeled
as COM1 on the Printed Circuit Board. The Jumper is labeled as J1 on the Printed
Circuit Board.
2. Carefully remove the Jumper. Lift the Jumper straight up and o of the PCI Express
Serial Card.
Note: Always hold the Card by the edges.
3. Determine the power setting that is required for Port One.
4. Position the Jumper over the set of Pins that correspond with the desired Serial
Port Power Setting. See Figure 1 to determine where the Jumper should be
positioned.
5. Push the Jumper straight down and into place.
Note: Push the Jumper all the way into position for proper contact.

6. Repeat these steps to congure the Jumper for Port 2. This Jumper will be labeled as
J7 on the Printed Circuit Board.

Hardware Installation
Note: This PCI Express Serial Card is specially designed to allow for power output
from the ninth pin of the Serial Connector(s) for devices that support power over
Serial. This card allows users to set each Serial Port to 5V, 12V, or RI (no power). Users
can also choose to draw the necessary power from the Computer’s Power Supply by
connecting to the LP4 Power Connector.
1. Turn o the power to your Computer.
2. Unplug your Computer’s Power Cord.
3. Remove your Computer’s Cover.
4. Remove the corresponding Full-Height or Low-Prole Slot Brackets from an
available PCIe Slot.
5. (Full-Prole installations) Remove the four Screws from the Low-Prole Brackets,
using Needle-Nose Pliers. Insert the Serial Ports into the Full-Prole Bracket, with
the Serial Port that is connected via Ribbon Cable on the left-hand side. Insert and
fasten all four of the Screws, using Needle-Nose Pliers.
6. To install the Card, carefully align the Card’s Bus Connector with the selected
PCIe Slot on the Motherboard. Push the Card down rmly to ensure the Card is
properly seated into the PCIe Slot.
7. (Optional): Connect the LP4 Power Connector Cable from the Computer’s Power
Supply to the LP4 Power Connector Port on the Card.
8. Replace the Slot Bracket’s Holding Screw to secure the Card.
9. Replace the Computer’s Cover and reconnect the Power Cord.
10. Download the latest Drivers. See Driver Installation for more details.
