Remote access to the web interface
There are two methods of getting remote access to the web interface:
• Using the AT command _IREMWEB, e.g. sent in an SMS (ATCO command)
• Using an EXPLORER 540 that is pre-configured with trusted IP addresses
The following sections describe these two methods.
To use AT commands to get remote access to the web interface
You can send the AT commands encapsulated in an SMS (ATCO commands). For details, see
Remote access with SMS on page 20.
Relevant commands:
_IREMWEB
Se ATCO commands on page 100 for syntax and parameters.
1. To use an SMS to allow access to the web interface for specific IP addresses, send the
following command:
ATCO <resp_mode> <rsms_pwd> _IREMWEB=1,<ip address>[,<ip address>]
Example: ATCO 2 remote _IREMWEB=1, 214.123.189.119
In this example the command specifies no immediate response, only when the global IP
address is sent along (2). The remote SMS password is remote and the IP address
214.123.189.119 can get remote access to the web interface (if two IP addresses are
listed, it is interpreted as a range of IP addresses).
2. The EXPLORER 540 should now return an SMS response with the external IP address of the
terminal.
Example: _IREMWEB:81, GlobalIP:161.30.181.31
81 is the response code for a remote web connection that was set up successfully. It is
followed by the global IP address, which is the IP address to enter in your browser to
access the web interface from the remote device with the IP address you specified in the
command.
3. On the remote computer, open your web browser.
4. In the address bar of your browser, enter the global IP address of the EXPLORER 540
(received in the response above).
Note
When using remote access, the web interface may take a long time to load the pages,
because the Internet connection may be slow.
Note
Only one PDP context at a time can be used for remote web interface access.
Note
If remote SMS command access has been disabled, you can enable it either using the
web interface or using AT commands. See To set up remote access with SMS on
page 69 and To set up the security with AT commands on page 27 (step 4.).
