Testing the Signal Quality
The signal quality at the INSYS GSM location can be tested as follows:
¾
Use the button "Read GSM field strength now" on the tab "Basic settings" in the
group "GSM connection" of the software HSComm.
¾
Use the AT command AT**SIGNAL?
The GSM signal should have a field strength of at least 12.
For lower values or the value 99 you will need to change the antenna location.
The value 99 means that the field strength can not be ascertained. This occurs during
network loss or if an antenna is damaged, for example.
The signal quality is indicated with an update interval of 1 minute (in idle state) by the
LED Signal:
