On the top of controller there is an infinite 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)
Changing the presets is easy by pressing down the knob on the top of the device.
You can 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 one more time the
knob and you will enable the encoder again.
Emergency Stop: When you click top knob, controller will cancel every motor rotation. This
is useful when you need to stop the motor instantly.
