Vision software Option 486 enables coverage mapping. Option 407 allows you to view live data, record data related to given limit lines, or record GPS-assisted measurement results. Use the Port Scanner menu to insure that the correct boxes are checked. Figure: Port Scanner Options and Settings Configuration shows a typical setup. Once you have verified your settings, start monitoring, recording and driving the route. All data is saved on the laptop’s hard drive. Because the data is gathered continuously, stop the measurement when you are finished.
