WARNING:
Antenna may not exceed the maximum gain specified in RF exposure (p. 49).
In more complex installations, such as those requiring long cable lengths and/ or multiple
connections, you must follow the maximum dBi gain guidelines specified by the radio
communications regulations of the Federal Communications Commission (FCC), Industry
Canada, or your country's regulatory body.
7.4 Hardware and software setup
You will need to know how your RV50(X) was configured, either with a private dynamic or public
static IP address. The Provisioning Report received from Campbell Scientific or another cellular
provider should provide this information.
See QuickStart (p. 8) for more information.
8. Operation and maintenance
8.1 Ports
The RS-232 port is the main port used with Campbell Scientific dataloggers. Its function is
described throughout this manual.
The USB port is not used in Campbell Scientific applications.
The Ethernet port may be used in place of PPP Mode to get to the IP stack of the data logger.
However, this method comes with higher current drain for both the module and the data logger.
See Using the RV50(X) Ethernet port (p. 45) for more information.
