 THIS CABLE IS DIFFERENT BY OLD ONES

 EHEH! NICE NEWS! WITH THIS I CAN PUT MY LAPTOP AT MAX 104 meters away
from the scope with only one cable: two webcams, autoguiding parallel
interface (much easy to build than lx 200) and future mod toucam pro!

laptop-usb-port<->usb-line-ext-trasmitter<->~~max104meters~~<->receiver<->4p
orts-hub<->2webcams,two usb to parallel cables!!!

 notes: hub is active, not passive and i have to decrease bandwidth for
one cam.... nothing of special but drivers must be designed to permit
bandwith regulation on usb device.

 FUTURE IS WITHOUT CLOUDS!
