SMS
Storage Locations
The number of available SMS storage locations on the SIM card is read out by the
button ‘
Locate SIM SMS storage locations now’
.
The controller queries the SMS storage locations in intervals of one minute. The
baud rate and the number of SMS storage locations to be configured determine
the duration of the query.
Example:
Baud rate
19200
Configured SMS memory
15
Query duration
5 seconds
The number of SMS storage locations, which should be considered by the control-
ler during its query routine, must be specified in the dialog box ‘
configured SMS
storage locations’
. A problem may occur if there are more incoming SMS than SMS
storage locations are queried. In this case, SMS are stored in the storage location
which is not considered by the query and can therefore not be processed by the
controller.
5.7.1.5
Connection Attempts
The number of attempts to connect if the remote terminal does not answer can
be specified. This setting is effective for:
Dispatch of messages (alarm or periodic alive SMS)
Connection set-up for alarm messages via a data connection
Connection set-up for security callback
Possible values are 1 … 12, default is 3.
The dispatch will only be attempted once for an acknowledgement SMS after a
configuration via SMS.
5.7.1.6
Detect Field Strength Intensity
The actual field strength of the GSM signal is read out and displayed as a diagram.
Values below 12 are poor – the antenna location should be improved. The value
99 stands for not ascertainable field strength, e.g. due to network loss or a dam-
aged antenna.
When the location of the antenna is changed, it usually takes 5 to 10 seconds until
the field strength of the INSYS GSM 4.2 easy is displayed correctly.
