6.2 External connections
6.2.1 Antenna connector
SMA antenna input is used to connect external GSM antenna. To establish connection
with GSM network an external antenna must be used. Type of antenna depends on GSM
coverage. In good circumstances (level of received signal is high) use antenna which is
attached in the package. If range of GSM is low or none, an outdoor or indoor (for instance
in place where GSM range is sufficient) antenna should be used.
Note: If there is no antenna connected to SMA connector, the connection with GSM
network is impossible.
6.2.2 Memory slot
RB800 can be optionally equipped with memory card slot to store all the measured
data. The slot type is microSD. Memory card can be controlled only by Python script using
special AT commands which is sends through SER2 interface, see chapter Python Script
Interpreter and AT Reference manual.
