At this moment the log in procedure is finished successfully. Next step is checking the GSM signal
strength. When the signal strength is evaluated the LED
RX
will also be switched off.
The evaluated GSM signal strength is visualized by the LED
Signal
. If the LED is illuminating this
means a good GSM signal strength, if the LED flashes GSM signal is poor.
The GSM signal strength and the LED
Signal
are updated every 60 seconds. When this actions
takes place the LED
Test
will flash.
When starting the KNX-GSM Gateway the current time needs to be adjusted. This is performed by
the KNX-GSM Gateway by sending a short message to it’s own mobile phone number. This action is
shown to the user by a blinking LED
Status
and an illuminating LED
Test
.
If the SMS sending fails the LED
Störung
starts blinking and the LEDs
Status
and
Signal
illuminate.
After sending the Test SMS successfully the KNX-GSM Gateway is waiting for the receiving. The
LED
Test
is switched off if the SMS is received successfully. After this SMS receive the system
startup phase is over and the KNX-GSM Gateway is ready for action.
Test mode
It is also possible to check if the KNX-GSM Gateway is in operation and is logged in the GSM net-
work even if you are on the way. You just have to call the KNX-GSM Gateway’s mobile phone num-
ber from any telephone. The KNX-GSM Gateway will accept the call and will answer with four differ-
ent tones. After these tones the gateway hangs up the call automatically.
Alarm input
The KNX-GSM Gateway offers an additional alarm input. This input offers the opportunity to connect
a contact of sabotage to the KNX-GSM Gateway. This contact can e.g. be a switch which can moni-
tor the door opening of your control cabinet. To use this alarm input feature the KNX-GSM Gateway
must be configured to activate the input. After the parameterisation the monitoring of the contact is
activated as soon as the contact is closed the first time.
