over the BGAN satellite network by accessing the built-in web interface. See Remote
access to the web interface on page 25.
• The distributors may have their own Graphical User Interface, which could be built on e.g.
Inmarsat's M2M API or similar. Contact your distributor for information.
To access the terminal using AT commands
The EXPLORER 540 supports a number of M2M specific AT commands as well as a set of
general AT commands. For a list of the most common commands, see AT commands on
page 99.
AT commands can also be encapsulated in an SMS sent to (and from) the terminal’s phone
number. See Remote access with SMS on page 20.
1. Connect your computer (or M2M equipment) to the EXPLORER 540 terminal.
You may connect locally to the terminal or use a remote connection.
2. On the connected computer, start a Telnet session.
3. Select TCP/IP and type in the IP address and port number.
•For local connection, use the local IP address of the EXPLORER 540 (default
192.168.0.1) and port number 5454.
•For remote connection, use the external IP address
1
of the terminal. The port number
for AT commands is normally 5454 but can be changed in the web interface Remote
management page under AT commands (see Remote management on page 68).
Important
Before putting the EXPLORER 540 into operation, remember to set up the
security features in order to avoid unintended use. See Security setup on
page 27.
1. The external IP address is found in one of the following ways:
1. If you are using SMS activation, you will receive an SMS with the IP address.
See ACTIVATE: Activate a data connection with an SMS on page 21
2. Otherwise, you can use the GETINFO (ALL) command to obtain the external IP address, if you
already have a session running.
This is the IP address you must use to access the terminal.
Note: If Static IP is included in your airtime subscription, we recommend using this static public
IP address for the terminal in order to provide easy access to the terminal. To use the static IP
address, you must set the APN source to SIM default. For details, see To change the APN for a
connection package on page 43.
