/**
\defgroup fc2machine FC2 NMR Spectrometer
\ingroup machines
Uses Spincore Pulseblaster 24 Bit and Spectrum MI4021, and some DACs
\par Starting the hardware
This procedure should assure the correct initialisation of the hardware:
\li Switch off main switches of SpinCore Pulseblaster and Computer (the main switch of the computer is at the rear)
\li Switch on Computer and start Windows or linux
