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)”.
