3. Operation
The
M7 GX
operates in a number of different “GPS Modes”, each mode specific to the application it is being
used in. The mode of operation is set with one simple command, the
GPS x

change the operation of the
M7 GX
in a number of ways. The serial-port data rate is set, the types of NMEA
formatted messages it will send out or accept is set, as will as how the internal UHF radio is used. The table
below summarizes this.
