Introduction
Universal Serial Bus (USB) port technology has emerged in response to the proliferation of external
peripheral devices (scanner, digital camera, portable hard-disk drive, cell phone, PDA, MP3 player,
etc.) that are increasingly being connected to the latest generation of PCs. The USB behaves in a
similar fashion to conventional bus ports like Serial (COM), Parallel and PS/2. As it doesn’t require
any IRQs, more devices can be attached to the system without conflicts.
This USB to Serial converter provides an external plug-and-play connection for RS-232 enabled
devices with PC or any computerizing devices that support the USB specification. The converter
comes with the standard connectors of Serial DB-25 or DB-9 and USB Type A or B to fulfill your
working requirements. With the link of USB to Serial cable, communication starts interacting
without any barriers.
For further convenience, this product is designed to work by using the power drawn from the
Universal Serial Bus and no external power is required. As it is an USB compliant device, features
of plug and play, hot-swapping, energy-saving suspend, and resume are provided.
Since the most computers have limited USB and COM ports, USB hubs can be employed to gain
more USB ports for numerous USB peripheral devices to be connected up with your PC at the time.

Windows 98 Installation Guide
If a device of the same type has been installed on your machine before and the drivers
that are about to be installed are different from those installed already, the original
drivers need to be uninstalled. Please refer to the uninstalling instruction.
Download the latest available drivers from the FTDI website and unzip them to a
location on your PC.
Connect the device to a spare USB port on your PC. This will launch the
Windows Add New Hardware Wizard. Windows may display a message reading
"Building driver database" at this point which may take a few minutes to pass.
Click "Next" to proceed with the installation.
Select "Search for the best driver for your device. (Recommended)." as shown below
and then click "Next".

7-60
· Check the box next to "Specify a location" and uncheck all others as shown below.
Click "Browse" and locate the driver files. Once the files have been located, click
"Next" to proceed with the installation.
Windows may display a message reading "Building driver database" at this point
which may take a few minutes to pass. Once Windows has found the required

8-60
files, click "Next" to install the device.
If the driver being installed does not have Microsoft WHQL signature files (.CAT files),
the wizard will request a driver disk to attempt to find them. Click "OK" on the "Insert
Disk" message box.
The following window will appear to assist in locating the file. To proceed with the
installation without the .CAT file, click "Skip File".

9-60
If the driver being installed is Microsoft WHQL certified, then the .CAT files will be
located with the other driver files and should be installed automatically.
Windows should then display a message indicating that the installation of the
serial converter driver was successful. The COM port emulation driver must now
be installed. Click "Finish" to complete the installation of the serial converter and
proceed to the COM port emulation driver.
Under Windows 98, the COM port emulation driver will be automatically installed from

10-60
the same location as the serial converter driver. However, if the driver is not WHQL
certified as explained above for the serial converter driver, the wizard will ask for the
location of .CAT files. Click "OK" on the "Insert Disk" message box.
The following window will appear to assist in locating the file. To proceed with the
installation without the .CAT file, click "Skip File".
If the driver being installed is Microsoft WHQL certified, then the .CAT files will be
located with the other driver files and should be installed automatically.

11-60
Open the Device Manager (located in "Control Panel\System" then select the ""Device
Manger" tab) and select "View devices by type". The device appears as an additional
COM port with the label "USB Serial Port".
Please note:
1. For multiple-port converter, each port has to be installed with the driver individually, i.e.
you have to repeat this installation procedure 2 times (2-port converter) or 4 times (for
4-port converter).
2. If you have any
difficulties with the drivers we provided in this CD, you may download
the updated or appropriate versions from FTDI Web site
www.ftdichip.com/Drivers/VCP.htm, supported device “FT232BL(M)”.

Troubleshooting
1. Windows 98 cannot find drivers for my device
This error can occur if the VID and PID programmed into the device EEPROM do not
match those listed in the INF files for the driver. The VID and PID programmed into the
device EEPROM may be found by using the USBView utility from the FTDI website.
These can then be checked against the VID and PID entries in the driver INF files. If
they do not match, that driver cannot be installed the VID and PID entries in the driver
INF files. If they do not match, that driver cannot be installed for that device without
either re-programming the device EEPROM or modifying the list of VID and PID
numbers in the INF files. Please note that only your own company VID and PID or
FTDI's VID (0x0403) and FTDI PID issued for use by your company should be used in
the EEPROM and INF/INI files.
2. Windows 98 forces a reboot after installing a device
This problem can occur if an application is accessing a file while the New Hardware
Wizard is trying to copy it. This usually occurs with the FTD2XX.DLL file. If installing a
D2XX device, selecting not to restart the computer then unplugging and re-plugging the
device may allow the device to function properly without restarting. Restarting the
machine will allow the device to work correctly.
3. Driver installation fails and Windows 98 gives error code 10
Windows error code 10 indicates a hardware error or failed driver installation. This error
may appear if a device has insufficient power to operate correctly (e.g. plugged into a
bus powered hub with other devices), or may indicate a more serious hardware problem.
Also, it may be indicative of USB root hub drivers being incorrectly installed. Please refer
to the example schematics on the FTDI website for standard device configurations. If
the error persists, please contact the FTDI support department.
4. Device hangs randomly during operation under Windows 98
This is not caused by the driver, but is a hardware compatibility problem. Some newer
USB 2.0 hubs and host controllers can be susceptible to noise and can cause random
device failures. This can be overcome by fitting 47pF capacitors to ground on the
USBDP and USBDM lines on the USB connector side of the 27W series resistors.
5. Windows 98 complains about missing .CAT files
Files with the .cat extension are signature files issued by Microsoft that indicate a device
driver is WHQL certified. If a driver is not certified, there will be no .cat files available.
When installing drivers in Windows 98 or Windows ME, the user is prompted to locate
the .cat files if the operating system cannot find them. If the driver is not certified but you
wish to install it anyway, the files may be skipped by clicking the "Skip" button.

15-60
6. Windows 98 complains about missing ftccomms.vxd file
This can occur when the USB Composite driver has been installed if the user has not
browsed to the location of the driver files. If this message appears, do not skip it but
browse to the driver file location. The wizard will then be able to correctly install the
device.
