4.1  Overview 
4.1.1  Operation Modes 
The NewStep Controller has two major Modes of Operation, REMOTE and 
LOCAL At power up, the Controller will default into REMOTE Mode. In 
REMOTE Mode the controller will respond to Computer Communications only 
and the Speed Adjustment Knob is disabled. In the LOCAL mode, the Speed 
Adjustment Knob is enabled and the Computer Communications is disabled.  
The Three colored LED (Yellow, Green, Red) on the body of the NewStep 
Controller is used to indicate the mode of operation of the Controller. Different 
colors in conjunction with blinking state represent different operating conditions 
of the NewStep Controller. The LED Status Table summarizes the possible states 
for the LED.  
A Solid Yellow indicates that the Controller is in REMOTE mode and only 
Computer Communications is active. A Solid Green is indicative of the 
Controller being in LOCAL mode, where only the Speed Adjustment Knob is 
active. A Solid Red is seen whenever a motion related error is detected. The 
motion related errors are “Motor Not Connected” and “Hard or Soft Travel 
Limit” detected errors. Also, a blinking Yellow is used when Firmware 
Download is in progress.
