Main Init Tab
The above screen shot shows the default configuration of the unit set to ET Command mode,
some of the settings are described below for more details refer to the Configuration Tool Userguide.
Default Mode
When the unit powers up it can start in 3 modes
ET Mode
- standard operating mode
AT Mode
- the unit behaves like a standard GSM/UMTS wireless modem where the user controls
the internal cellular module directly without using the MCU. – For further assistance on using the
ETM9xxx-xxx as an AT modem please contact ETM.
GPS-capture Mode
- data coming from a GPS connected to the serial interface is stored in the unit.
Miscellaneous
Switch to ET-mode locally when CD is active -
The unit will operate in ET command mode
whenever a dial in connection is active - useful for programming the unit over a dial up connection.
NOTE: Incoming CSD calls are only possible on UMTS/WCDMA when the modem does not have
an IP Address allocated (is not connected to the internet).
Do SIM PIN Check at Startup
- If this is checked, which it is the default configuration, the modem
will check to see if the SIM PIN is required and if it is the SIM PIN as entered will be sent to the
module.
If this option is unchecked then the modem will not check the SIM PIN nor will it send any of the
commands listed in the AT-Command list – refer to Configuration Tool Userguide for further details.
SMS Polling
Both ‘Read SMS Memory’ options should generally be checked, though the lower checkbox will
generally be greyed out.
Init AT-Command Table
Here you may set various initialisation commands that are executed at power up.
Caution
Do not uncheck the “Do SIM Pin
Check at startup”item unless you
are certain this setting is
applicable.
In typical operation the unit needs
this setting to be active to correctly
initialise the module, even if the
SIM has had its PIN deactivated
