5.4.1 GPS timing synchronization
C16 Series radar can synchronize its data with accurate GPS time. GPS Pulse Positive Second (PPS) signal provides the ability to calculate
the exact trigger time for each laser data point, which is useful for earth reference and other applications. The connection and performance
conditions of GPS timing module connected to radar are:

The serial data interface output from GPS receiver should be connected to the REC terminal of GPS wiring port on radar adapter box;

The PPS output from GPS should be connected to the PPS terminal of GPS wiring port on the radar adapter box;

The ground from the GPS hardware output wiring should be connected to the ground terminal of GPS wiring port on the radar adapter
box.

The serial configuration baud rate of the radar receiving GPS data output by default is 9600, 8N1.
