Thermit Gsm Module



The main module contains a GSM module and a RF-receiver module. The main module receives data from the wireless sensors 6 or 8 times per hour , and every hour sends the main module the last received sensor data to our central server. The main module can handle up to 32 sensors.

How can I see the mainmodule works

  • The mainmodule LED indicator should flash red one time per second.

      That indicates connection to the Teleprovieder*
  • The mainmodule LED indicator lights stedaily.

      That indicates that there is power to the module
      That also can indicate that the module is sending data (but it should only do that in a couple minuts, then it must start to blink again
  • The mainmodule LED indicator dos not light.

      That indicates no power to the module, try another poweroutlet, or if power is ok in the outlet, then try another poweradapter.

SMS (txt) commands

SMS (txt) can be sent to the main modules and the following functions are available via SMS.

Note USERID and PASSWORD is only required if the telecommunications company requires this in order to gain access to the telecommunications company APN. These commands are not normally used .

How do I force the module to send data to server

Send TXT with SND (SND must be with capital letters)

How do I change the interval for sending data to server

Send a TXT with ITV interval (where interval = minuts from 10 to 240) Default = 60 min. ITV ITV must be capital letters

How do I change the APN in the module

Send txt to the mainmodule _APN internet_ where the "internet" must be the accesspointname.

Who to change USERID

Send TXT with the command _USE test_ (USE smust be capital letters). Bemærk hvis userid skal være tomt for det pågældende teleselskab er det ikke nødvendigt at sende USE med mindre man tidligere har ændret det.


Send TXT with PAS test (PAS Must be capital letters). Remark ! If password must be blank, then it is not nessacerry to send PAS, unless you have done so earlyer.
