Grounding terminal
The GND terminal is designed to be connected to a grounding cable. You must use a
different grounding cable ended in a different grounding rod than the grounding
connected to the Franklin spike for lightning protection. Failure to comply with this
will expose the logger to lightening damage.
The wire must be made of copper and with an appropriate section. The grounding rod
should have the minimal resistance to the earth. Depending on the soil resistance a
special grounding installation (net) should be considered.

Modem
The
Orbit 360 data logger has an internal quad-band GSM-GPRS modem that works
worldwide. For CDMA or satellite communications an external modem is used, the
modem is connected to the loggers’ External COM port. The GSM antenna must be
connected to the antenna connector shown below:
