Device Operation Checking / Troubleshooting
In order to check that the Intelimax+ is operating correctly both locally and remotely
please follow the below procedures.
Local Checking:
In order to verify that the modem is operating correctly locally follow the below steps:
1. Check that modem Power LED is either solid on or mostly on. The better the signal
strength the more time the Power LED will stay on.
2. In serial modem mode:
a. Connect to modem with GUI via USB interface and check the registration
and signal strength of the modem. The status page will show whether the
modem is currently registered as well as showing the signal level in dBm,
which should be better than -93dBm.
b. Trigger a connection through the modem (either CSD or PPP connection)
and ensure that the data light will correctly flash to indicate data transfer
through modem.
3. In IP Stack auto mode:
a. Connect to modem with GUI via USB interface and check the registration
and signal strength of the modem. The status page will show whether the
modem is currently registered as well as showing the signal level in dBm,
good levels are better than -81 dBm.
b. Ensure that the modem has a data connection which should be
automatically set up by the IP auto modem connection function. If the
data LED is flashing then this connection has been established.
Remote Connection Checking:
In order to verify that the modem is correctly operating when the modem is remotely
located please follow the below steps:
1. In serial modem mode with CSD connection, dial into the modem data number:
a. If the response is ‘BUSY’ then the SIM card is not correctly provisioned.
b. If the response is ‘NO CARRIER’ immediately then the SIM card is off line
and not registered.
c. If the response is ‘NO CARRIER’ after some time, then the modem auto
answer is not working correctly but the SIM card is registered.
d. If you are able to connect to the modem (response is ‘CONNECT’, then
you can remotely check the settings on the modem by changing to an IP
mode and making a connection to the modem using the configuration
GUI.
