2.5V to 12V digital input
If the supplied voltage is greater than 12 V, connect an external resistor in series to Pin D. The resistor
value should be R = [(Vin-1.2V)/10mA]-330.

Encoder Input
Encoder input is provided by an external encoder and consists of 2 RS-485 signals. These signals are
connected to Encoder_A and Encoder_B.
