    They have a wiring diagram which shows the E-Stop wired from the GND of the DC 12/24V power supply to input 1 of the board (IN1). But you could use any of the inputs (IN1,IN2,IN3,IN4). What control software are you using (e.g. Mach. LinuxCNC)?

    With it wired like this it is just a software E-Stop (it relies on Mach to stop the machine for you). It's safer to also have a relay which can shut down your motors independently of the control software.
