Device Setup Instructions (Before running the application): 1. Open DeviceManager. On Windows 7, the Device Manager can be found at: Control Panel => Hardware and Sound => Device Manager. 2. In Device Manager panel, choose Ports (COM & LPT). Find out the port number from the list of ports. You can verify the port number by unplug and plug in the device. The port number, or ID, is whatever the number is at the end of the labels, eg. for (COM10), the port number is 10. 3. In the Application folder, find the ZStepperSettings.xml file. Open this file with text editor and find the tag name "Connection". In this tag, make changes if necessary to match the value of "portID" field with the port number from step 2 above.
