*If your serial device requires power output from
the serial port, connect the system power source to
board's power connector. However, most serial
devices do not require additional power through
the serial port. Refer to your serial device's manual
for more information.

Hardware Installation
Note: For Low Profile systems, replace the currently
mounted bracket with the included Low Profile bracket.
General instructions for installing the card are provided
below. Since the design of computer cases and
motherboards vary, refer to your computer’s reference
manual for further information, if needed.
Static Electricity Discharge may permanently damage
your system. Discharge any static electricity build up in
your body by touching your computer case for a few
seconds. Avoid any contact with internal parts and
handle cards only by their external edges.
1. Turn OFF the power to your computer and any
other connected peripheral devices.
2. Unplug the power cord from the back of the
computer.
3. Remove your computer cover. Remove the slot
bracket from an available PCI slot.
4. Set J1 and J2 jumper settings to the desired voltage
only if your serial device needs additional power
from the serial port. However, most serial devices
do not require additional power. For more
information see Jumper Settings on page 2. The
jumpers can be removed if power is not required. If
power output is required, connect the board's power
connector.
5. Carefully align the card's bus connector with the
selected PCI slot on the motherboard. Push the
board down firmly, but gently, until it is well seated.
6. Replace the slot bracket holding screw.
7. Replace the computer cover and reconnect the power
cord.
