System startup phase
Power up
When switching on the power supply the KNX-GSM Gateway switches
all LEDs on and off
. The
LEDs are switched one after another in the following order:
Status
Æ
Signal
Æ
Test
Æ
Störung
Æ
TX
Æ
RX
Æ
EIB
Check Parametrization
After Power up the KNX-GSM Gateway checks its parametrization. If the gateway is not yet config-
ured or the parametrization is incorrect or inconsistent the LEDs
Störung
,
Test
,
Signal
and
Status
are blinking simultaneously. In this case you have to configure the KNX-GSM Gateway
before you can use it (see „
Configuration with the EIBDoktor software
“).
Initialization
If the KNX-GSM Gateway is configured correctly the initialization phase starts. First, the gateway
checks if a SIM card exists in the SIM cardholder. If there’s no SIM card present in the KNX-GSM
gateway, the LED
Status
is switched on and the LED
Störung
starts
blinking
(ca. 1Hz). The
KNX-GSM gateway will stop in this state and no further initialization steps will be executed.
Important:
You have to switch of the power supply before inserting the SIM card in the SIM card-
holder! This is important to save the SIM card from damage!.
Next, if a SIM card is inserted in the KNX-GSM Gateway, the configured PIN is checked. If the PIN is
rejected by the SIM card, the LED
Störung
starts
blinking
(ca. 1Hz) and the LED
Signal
is
switched on
. In this case the initialization phase is also cancelled and the KNX-GSM Gateway stops
in the current state.
Note:
Normally SIM cards are locked if you enter an invalid PIN three times. If the KNX-GSM Gate-
way shows an invalid PIN, you have to correct your parameterisation and upload this parameterisa-
tion into the KNX-GSM Gateway. If you boot the KNX-GSM Gateway three times with an incorrect
PIN your SIM card will be locked! In this case the SIM card can not be used anymore in the KNX-
GSM Gateway. You have to unlock your SIM card with the corresponding PUK (Personal Unblocking
Key) in a normal mobile phone.
The LED
RX
will
blink
(ca. 1Hz) if the configured PIN is accepted by the SIM card. After the PIN
checking phase the KNX-GSM Gateway will try to log in to the GSM network. The LEDs
Status
,
Signal
and
Test
will show the current state of the log in action. Thereby the three LEDs will be
illuminated in the following order:
•
Status
