Clock+
Positive SSI clock input.
Clock+ together with clock- forms a current
loop. A current of approx. 7 mA towards
clock+ input means logic 1 in positive logic.

Clock-
UP/DOWN
Preset input for setting a preset anywhere
within the programmed encoder resolution.
The preset operation is triggered by a High
impulse and has to be in line with the
selected rotating direction UP/DOWN.
Connect to GND for maximum interference
immunity. Impulse duration >100 ms.
UP/DOWN counting direction input.
This input is standard on High. UP/DOWN
means ascending output data with clockwise shaft rotation when looking at flange.
UP/DOWN-Low means ascending values
with counterclockwise shaft rotation when
looking at flange. The rotating direction
may also be altered by programming.
TxD
Encoder transmitter output for RS232
programming interface.
RxD
Encoder receiver input for RS232 programming interface.

Negative SSI clock input.
Clock- together with clock+ forms a current
loop. A current of approx. 7 mA towards
clock- input means logic 0 in positive logic.
