This image shows you a typical installation of one of the QS6001 QuickSilver™ sticks in the wild. The interface connector isn’t strictly necessary, but each of the units comes with one, and we find it very convenient to use them, and some simple quality Velcro to mount the unit in place. The only thing not shown here is the power supply – but it’s a very simple wall-wart type of device that just gets plugged into the side of the stick.
Funnily enough, we have a couple of monitors here in the office that have a USB output, and although we do NOT recommend that as the USB specification doesn’t actually allow for it, some of them will power the stick with nothing but a USB lead – not recommended as an approach!
