I bought a few days ago a Durst 138 s with the b&w head plus a CLS 100 "color head" and the CCD 100 "control" unit, wich was a bonus. The seller didn't know how to operate that unit. Can anyone tell me what it does and how? I don't understand nothing of it, it has a lot of buttons but very few of them are familiar to me, except the "focus", "stop", "start" and "on/off". I couldn't find nothing on the web about this CCD 100 or CLS 100.
