Because there is no 5V on the parallel port? Using a common 0V allows the Gecko to connect directly to the LPT port, something that is simply not possible with the Chinese drives or others that use 5V common. Or I didn't understand your question...
" I got a G203V in the post today, and am confused. Why on earth do Gecko drives use a common ground on the inputs, especially if they're targetting the parallel port market? Even the ching drive referred to in this discussion has it the right way, a common Vcc.
