USB Interface
6.3.3.1 General
The USB interface of the Teslameter FM 302 is realized with the FT232R, a
USB-to-serial converter from Future Technology Devices International Ltd.
(FTDI, http://www.ftdichip.com/).
That means, that the Teslameter FM 302 creates a virtual serial port after it
has been connected to a PC. For communication every ordinary terminal or
terminal program is suited. The control takes place text oriented which
makes it easy to integrate the Teslameter into existing environments.
The necessary USB driver can be found at the CD which is included in
delivery (see also section 5.3 Items Supplied). The newest drivers can be
found at the homepage of FTDI under the menu Drivers – VCP Drivers
(http://www.ftdichip.com/Drivers/VCP.htm).
6.3.3.2 Driver Installation Windows
Windows 7 and above contain the driver for the FTDI chip. Connect the
instrument to a free USB port of your computer. Windows automatically
detects the new device and installs the driver. This may take a moment.
Alternatively the driver from the included CD or from the website of FTDI can
be used.
Further installation guides for different versions of Windows are available (in
English language) at the homepage of FTDI.

Linux contains the necessary drivers since kernel version 2.6.31. A separate
driver installation is not necessary.
