Installing the driver for the cable
The USB–serial cable requires a specific driver to be installed on the computer. It is
available from www.ftdichip.com/Drivers/VCP.htm. Select the latest
Windows®-certified driver that is suitable for your computer.
To install the driver for the cable:
1 Download a suitable Windows®-certified driver from
www.ftdichip.com/Drivers/VCP.htm.
1 Double-click on the self-extracting .exe file.
NOTE: Some older drivers are delivered as a zip file. Extract the files
(using folder names) from the zip file. Right-click on the
ftdibus.inf file, then select Install.
Identifying the COM ports used by a USB–serial connection
When you connect the computer to the device via a USB–serial cable, the computer

ports when selecting a COM port for the email client.
To identify the numbers of the COM ports used by the USB port:
1 On the desktop of the computer, right-click on the My Computer icon, select
Properties—[Hardware]—Device Manager.
1 Connect the USB cable between the device and the computer.
1 Wait for two new ports to appear in the Device Manager under Ports (COM &
LPT).
You need to use the higher COM port in the email client.
