===X2 pinout===
{{damage|Connect X2 only to 3.3V or 5V logic systems.}}

X2 is main control and [[setpoint]] signal port consisting Global Enable input signal, Global Fault output signal, [[pulse and direction]]/[[PWM]] setpoint inputs and digital outputs for servo ready signals. X2 is directly wired to conform most common parallel port style pulse & direction CNC controllers.
