GSM parameters
This tab contains parameters related to SMS communication, including access to SMS
phonebook settings.
Recently, the formerly widely used prepaid credit SIM cards have taken a back seat and
the use of flat-rate SIM cards, which usually include a certain amount of free data, has
become more widespread.
For this reason, and also because the information about the remaining credit on the
prepaid SIM provided by the operator often changed in the form and structure of the
informative SMS, the device's FW stopped supporting the automatic calculation of the
remaining credit on the prepaid SIM card. Therefore, if the user selects an option other
than "General flat rate card" in the device parameters for the SIM card type, the calcu-
lated remaining credit will most likely not correspond to the reality.
The other GSM communication parameters can be left in the basic settings except for
the command line for setting the content of the periodic or informative SMS. This com-
mand line should be set according to the actual channel occupancy and the require-
ments of the station operator. The list of codes used in the command line is given in the
table on page 41.
Note: The H40G will also respond to incoming SMS containing individual codes sepa-
rated by a comma after the password.
The importance of other parameters will be explained in the chapter "SMS com-
munication".
