Test GPS with Listing
After all the settings above have been input and the GPS receiver is attached to the serial port on the DVL,
the test option allows the user to check that the DVL is receiving the GPS output.
If the NMEA strings are successfully being read by the DVL they will appear on the DVL screen. This is a
good time to note the prefix of the last NMEA string in the list and input it in the End String setting above.
If the NMEA strings do not appear, check that the port settings are correct. It is also possible that a
crossover cable is required between the output cable of the GPS receiver and the serial port on the DVL.

Test GPS with Plotting
Once the GPS system is running successfully, selecting Test GPS with Plotting can be used to graphically
display the GPS data. This screen displays the GPS Time, Latitude, Longitude and Altitude as well as
other values indicating the accuracy of the GPS reading. The GPS position is also displayed in a square
that can be Zoomed from 2 metres square to 16384 metres square.
