7.9.3 Modem Connection using Ethernet
In some cases it may be desirable to connect using the Ethernet
interface available on the 4GMini/4GPlus cellular modem. To
do this, a CR1000 or CR3000 with either a NL120 Ethernet
Interface, NL116 Ethernet/Compact Flash Module, or any
datalogger using a NL2XX series device is required. A
crossover Ethernet cable is needed to connect the two devices.
Please review the literature for the specific interface for more
details.
7.10 Testing the Cellular Connection
After the Device Map has been configured, it is recommended
to test the cellular connection using the
Connect
screen. Click
on the appropriate station, then click the
Connect
button to
initiate a call to the datalogger. Be sure all connections are
complete and power is supplied to both the modem and
datalogger.
If the call is successful, the connectors at the bottom of the
screen will come together and time information from the
datalogger will be displayed the
Station Date/Time
field. If the
connection fails, a
Communications Failure
message is
displayed.
