4 SOFTWARE & CONFIGURATION
4.2.3
Other Data Download Options
Decagon designed the Em50R to be part of a wireless sensor net-
work. In this mode, the Em50R transmits measurement data to a
DataStation. You can then download the measurement data from
all the Em50Rs in your network from one location. The communi-
cation protocol also confirms delivery of the data and continues to
request data until it receives the complete data package. See Section
6: "Em50R Radio Telemetry" for more information on setting up
logger networks.
We designed the Em50G logger to upload your measurement data
to Decagon Data Service using the cellular network. This makes it
easy for you to use the Internet to download your measurement data
from anywhere in the world. Please see Section 5for more informa-
tion.
Note: ECH20 Utility uses the default conversion equation for each
sensor when converting raw data to processed data. For more infor-
mation about the default conversion equations, please see your logger
or sensor manual.
An Em50R supports wireless data downloading. ECH20 Utility can
establish a two-way radio connection between your computer and a
remote Em50R through the Rm-1 Radio Modem. Once you estab-
lish this connection, you may download data from the Em50R just
like it is directly connected to the logger. Section 6 provides more
information on setting up two-way wireless communications.

Erasing Data
If you need to erase the data on your Em50, go to Data
Stored Data. You should erase your data if you change the Em50
configuration settings, such as what type of sensor is in each port.
After selecting the Erase option, it asks if you want to continue.
Click Cancel to return to the program, or Erase Data to continue.
