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. 

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.  

 
 
 
 
 
 
 
 
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!.
