Rotary Encoder Knob 

On the side of controller there is an infinite turn - rotary knob. This digital encoder knob simulates your 

focuser’s knob. In every small step turn, motor will respond clockwise or anticlockwise. 

Rotary encoder has two presets. The fast step (50 steps in every click of your turn). and 1/10 reduction. 

(5 steps in every click of your turn) 

Switching these two pre-sets is easy by pressing down the knob on the side of the device. 

You can also disable the encoder functionality by keep pressing the knob for two seconds. Led will turn 

to orange and the encoder will not obey at your commands. Press the knob one more time and you will 

enable the encoder functionality again. 

 

  Emergency Stop: When you press the knob, controller will halt every motor operation. This is 

useful when you need to stop the motor instantly. 

 

LED Indications 

Yellow Light 

Knob encoder set to 1/10 speed (5 steps) 

Green Light 

Knob encoder set to normal (20 steps) 

Orange Light 

Knob encoder is disabled 

 

Please  note  that  rotary  encoder  is  in  operation  in  parallel  with  PC  commands.  They  both  work 

simultaneously and update the exact position of the motor.
