Programming the GSM Intercom
SHUTDOWN AND RESTART (RBT)
This command feature allows the GSM LITE intercom to be remotely shutdown and then rebooted again. The following command
can be sent to the GSM module.
1111RBT
Shutdown and restart the GSM module.
IMPORTANT NOTE: This feature should not be confused with the ‘hard-wired’ reset (described on page 26). The RBT function
simply powers down the GSM module and then powers it back up again.
SIMULATE A BUTTON PRESS VIA SMS MESSAGE FOR BUTTONS 01-04 (BUT)
It is possible to simulate a button press (for the call button range 01 - 04) on the intercom by sending the following programming
command, shown below, to the GSM LITE intercom. This feature can be useful if there is suspected fault with a call button or if there
is an issue with the wiring for the buttons into the GSM’s button matrix.
1111BUTnn
Simulate a button press for button number nn, where nn = button number 01 - 04.

OBTAIN THE GSM’S IMEI NUMBER (IME)
If the IMEI number (unique 15 digit number of the main internal hardware chip) of the GSM LITE intercom is required the following
text message can be sent to obtain the number.
1111IME?
Query IMEI number of the GSM module, also send confirmation to the sender.
Example:
Obtain IMEI number of the GSM module, the following message can be sent to the GSM intercom:
1111IME?
The GSM LITE intercom will reply with the following text:
IMEI-357803045065535
OK VIDEX GSM
IMPORTANT NOTE: If installing the GSM LITE for the first
time, when registering the SIM card with the chosen network
provider they may ask for the IMEI number of the GSM module.
As the programming command described above will only work
with a SIM card that has already been registered with a network
the command will not work.
Instead to obtain the GSM’s IMEI number, which is located on
the main hardware chip internally, the GSM module will have
to be opened. The IMEI number is printed on the Telit chip label
just below the model number, as shown in
Fig.61
.
IMEI: 357803045065535
GL865-DUAL V3
IMEI: 355856050228416

It is recommended that you contact Videx Technical on tel: 0191 224 3174 for UK based customers and Videx Customer Support:
+39 0734 631669 for overseas customers for advise on how to do this.
Alternatively use a SIM that is already registered with another network provider and fit it into the GSM LITE intercom (following
the procedure on page 25 for initialisation), then use the programming command above 1111IME? to obtain the GSM LITE’s
IMEI number so that when registering the actual SIM that will be used with the GSM LITE with the chosen network you will have
the appropriate IMEI number to hand.
