GND Encoder ground connection relating to UB. Data+ Positive, serial data output of differential linedriver. Data- Negative, serial data output of differential linedriver. Clock+ Positive SSI clock input. Clock+ together with clock- is forming a current loop. A current of approx. 7 mA towards clock+ input means logic 1 in positive logic. Clock- Negative SSI clock input. Clock- together with clock+ is forming a current loop. A current of approx. 7 mA towards clock- input means logic 0 in positive logic.
