Installation
WARNING! PCI Express Serial Cards can be severely damaged by static
electricity. Make sure that you are properly grounded before you open the
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 Configuration
Note: This PCI Express Serial Card is specially designed to allow for power output
from the ninth pin of the Serial Connector(s) for Serial Devices that support power
over serial. Jumper configuration is a requirement when connecting Serial Devices
that require power through a Serial Connector.
The Jumper can be moved into one of three different positions in order to set the
power output voltage for the Serial Connector. The default setting for the Jumpers
is RI, no power. The LP4 Power Connector must be connected after configuring the
Jumper to 5V or 12V of power. To configure the Jumper, complete the following:
1. Ensure the Computer's Power is Off.
2. Determine the power setting that is required for Port One.
3. Locate the Jumper for Port One and carefully lift the Jumper straight up and off of
the PCI Express Serial Card.
Notes: The Jumper for Port 1 is labeled as J1 on the Printed Circuit Board.
Always hold the Card by the edges.
4. Position the Jumper over the set of Pins that correspond with the desired Serial
Connector 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.
