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 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".
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 98SE, the COM port emulation driver will be automatically installed from 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".

USB to RS-422 / RS-485 Adapter
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.
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)”.
