Instruction Manual

31
Three categories of output data are possible (NMEA,
differential and raw data) but in most rover applications, only
the use of NMEA messages makes sense.
However, to allow raw data to be recorded in the rover, you
should make sure the appropriate messages are set on the U
and M ports.
Follow the instructions below to program the desired
messages:
•On the Configuration tab, click on the Data Output menu.
• Click on the NMEA Messages submenu. Use the page that
opens as explained below:
– All possible NMEA message types are listed below.
