Hi Philip

The connecting lead is a serial cable and you need to speak to someone at www.g-codetechnology.co.uk for the connection diagram - from memory, there are very few connections to make. They also supply upgrades for the dated controler. I may be wrong here, but I think you only need the Galaad 'Kay' licence to drive the machine [no dongle,200 euro]. You can use free stuff to design and create toolpaths.
