Start with the Demo Setup above and add an RS-232 cable connection to your computer as shown in Figure 3. The RS-232 connection is used with a terminal program to provide a basic terminal interface for the stepper motor. If your PC has USB and does not have a serial port, you may use the Silicon Laboratories CP2102 EK to provide a virtual COM port connection.
