4.3.1 No response on commands
INSYS GSM 4.2 easy and the terminal device (configuration PC or controller) have
to operate the serial interface with the same baud rate and the same data
format.(Default: 19.200 bps, 8N1)
The INSYS GSM 4.2 easy can be reset to the factory settings by pressing the Reset
key for an extended period (> 25 seconds).
4.3.2 No connection established
Check the signal quality of th GSM network.
Has the INSYS GSM 4.2 easy been logged in?
Has the SIM card been enabled for incoming data connections?
Was the phone number for the data connection dialed?
Is the power supply during sending sufficient?
4.3.3 Alarm SMS is not dispatched
Was the SMS service center number entered correctly?
Was the SMS destination number entered correctly?
4.3.4 Signal Quality
The query of the signal quality at the reception location takes place using the
button Detect GSM field strength now at the tab Basic settings or using the AT
command AT**SIGNAL?. The response should deliver a value larger than 12; the
best value would be 31. If you experience difficult signal conditions, change the
antenna location. The response 99 indicates that no field strength can be detected
(e.g. for network failure, defective antenna).
