PROGRAMMING AND DIAGNOSTICS OVER THE INTERNET
The system parameters may be changed and the system status may be observed by connecting over
the internet. The data are transmitted according to TCP/IP protocol; the GSM module connects to the
internet via a GPRS cannel. The connection is established by the GSM alarm configuration tool
GAprog. The application is downloadable from the website of the manufacturer at
www.eltech.lt
.
Two conditions are necessary for connection over the internet.
The first condition: GPRS service should be activated for the SIM card of the GSM module.
Usually, GPRS service is activated automatically. You may contact your GSM service provider to
inquire about activation of the GPRS service.
The second condition: The GSM module or the computer that is used for connection to the
GSM module should have unique IP addresses. A unique IP address also is called a real address or
an external address. An external IP address is accessible from any internet-connected computer. An
IP address is automatically provided to the GSM module by the GSM network. Inquire your GSM
service provider to find out, if your SIM card has a unique IP address. Inquire your ISP to find out, if
your computer has a unique IP address.
Before connecting to the module, it is recommended to verify access point settings. Send the
following SMS message to GsmAlarm-500:
or
(if SMS password is deactivated )
The massage returned to the user by GsmAlarm-500 contains the access point name, the login name
and the login password:
AAAAAAAA APN:internet.tele2.lt, APLOG:wap, APPASS:wap,
Adjust the access point name, the login name and the login password as required. In Lithuanian
networks OMNITEL and BITE GSM, all fields may be blank (comma after colon). The access point
name of TELE2 network is internet.tele2.lt , other field may be blank. The SMS message with
adjustments is sent back to the GsmAlarm-500 module.
There are two ways to connect to a GsmAlarm-500 module over the internet.
The first method: the user connects to the GSM module (the module operates as a server). This
method is possible only if the GSM network has assigned an unique IP address to the module. The
user sends an SMS message to the GSM module:
or
(if SMS password is deactivated)
The GETIPA command activates the GPRS interface of the GSM module and the “server” mode.
The GSM module sends connection data to the user: the IP address and the port number. The user
should mark the option “Connect to GSM module” in the window “Connect over GPRS”, enter the IP
address and the port number, click the button “Connect”, and wait for establishment of connection.
The second method: the GSM module connects to the computer of the user (the module
operates as a client). This method is possible only if a real (unique) IP address has been assigned to
