Press GPS Setup to see the screen in Figure 4-24.
The following buttons are explained below:
o GPS Mode –you can select whether to use the internal GPS, external GPS or no GPS at
all (Off).
Note that, due to limited accuracy, the Internal GPS cannot be used to position Line
Scans in MapView; only the External GPS will do this.
Ensure that you have the right GPS selected prior to your survey.
o Format – GPS units can be either UTM (Universal Transverse Mercator) or
Latitude/Longitude coordinates
o GPS Test – pressing this will return to the screen in Figure 4-22
o Serial Port Power - the serial port on the back of the Display Unit can output power,
thereby enabling a single cable to be used for the GPS (power and data). When you
purchase a GPS from Sensors & Software, this cable is included. However, if you use a
rd
3 party GPS, you need to determine if the GPS can accept power via the serial port.
Pressing the On button will turn power to the serial port on, but it will display a warning
message first (Figure 4-25). Press Off to disable power to the serial port.
