2. Remove the computer cover. For more detailed instruction on how to perform this
step, please refer to the documentation that was included with your computer at the
time of purchase.
3. Locate an empty PCI Express slot, removing the metal bracket covering the
accompanying empty port/socket.
4. Position the serial card above the open PCI Express slot, ensuring that the card is
properly aligned with the slot. Insert the card firmly into the slot, distributing force
evenly across the length of the board. Once inserted, secure the card into the
adjoining socket (previously covered by metal bracket), using the correct size screw (if
necessary, please consult documentation that accompanied purchase of computer).
5. Replace the computer cover and re-connect all power to the computer.

Windows will detect the PCI serial card, and prompt for driver installation. When asked
to specify a location where the driver is located, insert the driver CD into your CD/DVD
ROM drive and browse to one of the following locations, based on the operating system
that is installed on the computer. Once you have specified the correct file, click OK to
complete the driver installation:
Windows 95/98SE/ME: D:\IO\PCI IO\Win9x *
Windows 2000/XP/2003 Server: D:\IO\PCI IO\win2k & xp & 2003 *
Windows NT 4.0: D:\IO\PCI IO\WinNT *
Windows CE.NET: D:\IO\PCI IO\WinCE*
*Please note: D:\ specifies the CD ROM drive
DOS:
Following the physical installation of the PCI Express card, you will need to install the
necessary drivers. For detailed steps on how to do so, please consult the text file
located on the software CD ROM in the following path: D:\IO\PCI IO\DOS *
Linux:
Following the physical installation of the PCI Express card, you will need to install the

Verifying installation
Once the serial card and the accompanying software has been installed, please launch
the Device Manager (Start > Control Panel > System > Device Manager) to verify that
the hardware has been successfully installed. Once the Device Manager has loaded,
please click on the (+) symbol located next to Ports (COM & LPT). Check to see that
the correct number of ports appears in this section. For PEX2S650, you should notice
two additional serial ports. For PEX4S650, you should notice four.
Port Settings
Once you have verified that the serial card has successfully been installed, you can
modify the setting for each serial port from within the Device Manager:
1. Right-click on the newly installed COM port(s), and select Properties.
2. Select the Port Settings tab to modify COM port settings as needed.
3. By clicking on the Advanced button, you can modify the COM port number, as well as
the FIFO settings.
