Extrovert 4G LTE Modem for EMEA/NA
NWK200
Technical Functions (cont.)
Configuring Access Point Name (APN) (cont.)
Configure the APN using Windows
Windows 7 users should use Skylight. Windows 8 and 10 users may use the Windows connection manager by clicking the network icon
(“PC and cable” or “signal bars”) in the system tray and selecting Network Settings, then clicking the cellular network connection in the
new window and selecting the option for APN settings.
Alternatively users can navigate to Settings -> Network & Internet
Configure the APN using AT commands
Ubuntu users can use minicom (see above sections “Connecting to the modem via…”) to configure the APN by sending AT commands
through terminal.
Windows users can use PuTTY (see above sections “Connecting to the modem via…”) to configure the APN by sending AT commands
through terminal.
The AT command
AT+CGDCONT
is used to set the APN using the format:
AT+CGDCONT=<index>,”<IPType>”,”<apn>”
For example,
AT+CGDCONT=1,”IP”,”internet.carrier.com”
AT Commands
Report current status
View operational status of modem using AT command
AT!GSTATUS?
Switching SIM Card Slots
The NWK200 comes with two built-in SIM slots. It does not have any provision for automatic SIM switching, so a user must intervene in
order to change SIMs. SIM slot 1 on the card connects to UIM0 on the modem. SIM slot 2 on the card, or any motherboard or external
slot, connects to UIM1.
• To select the “operating” SIM slot, run
• AT!UIMS=n Where n is 0 or 1
• A password is not required for this command.
If an error is received switching to UIM1 then it is currently disabled (likely by a modem reset).
Use AT!CUSTOM=”UIM2ENABLE”,1 to enable UIM1.
IMPORTANT NOTE: Hot-swapping a SIM card (e.g. via external slot) may reset the selected UIM at which point it will have to be
configured correctly again.
Password-protected AT Commands
Some of the EM7455’s AT commands are protected by a password and will return an error if a password has not been entered. To
enter the password, from the terminal, send
AT!ENTERCND=”passwd”
