Hallo,
also der Ilda Standart schreibt Dieses:
Controls the horizontal beam position. This is a bipolar analog signal whose voltage range is 10V peak-to-peak differential.
A differential voltage level of -10V shall deflect the laser beam to the left side of the projection area. A differential voltage level of +10V shall deflect the signal to the right side.
A differential voltage of +10V occurs if the normal signal line has a voltage level of +10V with respect to the voltage level of the inverted signal line. When compared to the ground level of the differential driver, the voltage level of the normal signal line shall be +5V and the voltage level of the inverted signal shall be -5V
Und für die Y Achse das gleiche
Aber es gibt doch bestimmt die möglichkeine das Signal abzuschwächen.
