How far away can the touchscreen be from the computer?
It depends on the touchscreen controller configuration. If you use a serial controller, either internal or external, then the distance between the serial controller and the PC can usually be up to 200 feet. Short-haul modems can be used as necessary beyond 50-200 feet. Note that VGA cable lengths will probably be the limiting factor, as video amplifiers or specially shielded cables are generally required beyond six feet. With AccuTouch bus or external serial controllers, you can build your own straight-through cable and easily extend up to 50 feet. While usually not a problem, noise from long cables will be indicated by excessive coordinate jitter. When using the USB touchscreen interface, distances of up to 95′ can be achieved by daisy-chaining our USB extender cables. For maximum distance applications, our KVM extender can be used to extend video and serial touch up to 1000′.
