3. General operation
The general operation of David30 is related to the Tersus Survey Nuwa
application, which is introduced in the software manual. This chapter describes
how to do the hardware connection only.
Install the radio antenna before switching the radio transceiver to
transmit mode, or the radio transceiver may be damaged due to
overheating. The energy to be transmitted cannot be emitted out
without the antenna, which may cause the temperature rise and
overheat of the radio module.
3.1 Install the GNSS antenna
Connect the AX4E02 GNSS antenna to David30 with the GNSS antenna cable.
Please ensure the connectivity is reliable.
!
The ideal place for a GNSS antenna is a point without GNSS signals
blockage from horizon to horizon and is far away from any potential
interfering source. The specific distance depends on type of the
interfering source.
To make David30 work properly, the customer needs to provide
qualified power to David30 (refer to chapter 5 for requirement),
power to the 28W radio (if 28W radio is used, refer to chapter 5 for
details) and an Android device to run Tersus Survey Nuwa app.
David30 may be damaged if devices from other companies are
used to replace the ones in the package. And the warranty may be
void if this situation happens.
