The controller scans the SMS memory locations in 1-minute cycles. The baud rate
and number of assigned SMS memory locations determine the duration of the
scan.
Example: Baud rate 19200
Assigned SMS memory 15
Duration of scan 5 seconds
The number of SMS memory locations that the controller has to take into
consideration during its scan routine must be specified in the ‘Assigned SMS
memory locations’ field. A potential problem can occur if the incoming SMS
exceed the scanned SMS memory. In this case, SMS are stored in the memory area
not taken into consideration by the scan and can thus no longer be processed by
the controller.
5.7.1.5 Selection Attempt
The number of object selection attempts can be specified for the situation where
selection is not immediately successful. This setting is active for the following:
• Transmittal of messages (alarm or routine SMS)
• Establishment of connection for alarm messages via a data connection
Establishment of connection for security callback.
Possible values are 1 to 12 (default is 3).
Only one transmission attempt is made for a confirmation SMS following a
parameter assignment via SMS.
5.7.1.6 Detect Field Intensity
The current field strength of the GSM signal is read out and graphically displayed.
Values below 12 indicate a weak field – the antenna should be relocated. A value
of 99 indicates that the field strength could not be determined, e.g., due to power
failure or damaged antenna.
If the antenna is relocated, a period of 5 to 10 s normally elapses before the field
strength is displayed correctly by the INSYS GSM 4.2 LOGO!.
