FTDI virtual COM port driver for SC and AC circulators
The communication between a PC (i.e. RheoWin) and the SC and AC circulators relies on a
virtual COM port driver which causes these circulators (which have
an USB interface) to appear as devices with a serial COM port to the PC (i.e. to RheoWin).
This driver (FTDI USB driver) must be installed separately and is available for download here FTDI USB Driver (*.zip file, 0.9 Mb)
