9. Troubleshooting
If LoggerNet/PC400W software is unable to establish a connection with the
modem:
1.
Check the account information (a phone call to the provider may be
required).
2.
Verify that there is coverage at the location.
3.
Check the SGNL Indicator LEDs on the front of the modem.
Ensure that the modem has successfully connected to the cellular
network.
4.
Make sure the modem and datalogger have sufficient power.
5.
Check the RSSI LEDs on the front of the modem or in the Web
Interface. If the measured signal strength is less than –110dBm no
LEDs will be illuminated. If the signal is greater than –105dBm, 1
LED will be on, - 100dBm equals 2 LEDs and any signal greater than
– 95dBm will show all 3 RSSI LEDs to be ON.
6.
If using a Dynamic IP account, a dynamic domain name server
(DDNS) name that LoggerNet can reference to make the connection
will be required.
