    7. Complete the installation.
    8. The required USB drivers to use the EVM are installed in your PC.
  2. Please follow proper safety precautions working with sensitive electronics as well as high voltage and high current hardware.
  3. Power sequencing: The USB cable must be plugged in first between the EVM and the computer. Then turn on the power supply to the EVM. Powering the EVM external bench supply before connecting the USB cable can cause the USB device to not start up properly and result with driver error.

  4. Setup the bench supply to 12 V with current limit set to appropriate requirements of the Stepper motor (up to 5 A can be required to avoid triggering UVLO in the motor driver IC).

  5. The computer then recognizes the USB device is connected and enumerates as serial ports in the system as shown below. The COMxx numbers can vary according to your system.
