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 Configuration
Note: Jumper configuration is a requirement when connecting Serial Devices that
require power through a Serial Port.
This Jumper can be moved into one of three different 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 configure 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 off 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.
