The FTDI USB driver provides a virtual COM port when the ZMC board is connected to the computer via mini USB J6.
On some computers (x64), it is necessary to manually install the FTDI driver. You can check if the driver is installed correctly by following the installation checklist.

To install the driver

1. goto <LabVIEW 2011 installation folder>\Targets\Schmid\FTDI\
2. open the folder matching your system (32bit or 64 bit)
3. run dpinst.exe
