Introducing the CyberSerial Dual PCIe-DB
The CyberSerial Dual PCIe-DB high-speed serial I/O card
provides two additional 9-pin serial ports.
Features and Benefits
• Compliant with PCI Express Base Specification 1.0a
• PCI Express 1-lane (x1) serial I/O card works with
PCI Express slots with different lane width
• Installs into any available PCI Express slot and
provides two 9-pin RS232 serial ports
• 32-byte FIFO buffers dramatically increase data
transmit/receive speed and supports data rates up
to 230 Kbps
• Works as standard RS232 port or with 5V or 12V
power output for devices that require power
System Requirements
• PCI Express-enabled system with an available PCI
Express slot
• Windows 2000/XP/Server 2003

* Note: If the serial port requires power output,
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
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’s 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’s cover.
4. Remove the slot bracket from an available PCI
Express slot.
5. Change 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.
6. Plug-in the Connector bracket with 9-pin serial
port to Serial port 2, position the ribbon cable so that
the stripe is on the side farthest away from the slot
bracket. See Layout on page 2 for this connection.
Skip this step if only one serial port is needed.
