Including a ? at the end of the command the GSM intercom will reply with the following text:
MEM OPEN 004 = 01912243174,A3
MEM OPEN 005 = 01912241558,A2
MEM OPEN 006 = 07771234567,A1
VIDEX 4G
In the example the DTO numbers are stored from memory location 004 onwards as this is the next available location
and the access level for each DTO number is shown after the telephone number being stored.
CHECK/SET DATE & TIME CLK
The check date and time feature relies on the network providers time zone setting (also refer to notes on source of time/date
updates on pages 62 - 63). After a SIM has been placed into the GSM intercom and powered up the SIM will attempt to register with
the network and automatically synchronise with the network providers time zone setting. The following text messages can be sent
to the GSM intercom to check and set the current time and date. The date and time format is as follows: yy/mm/dd, hh:mm, where
yy = year, mm = month, dd = date and hh = hour, mm = minutes.
1111CLK? Check current time & date and send a conrmation text back to the sender.
1111CLK”yy/mm/dd,hh:mm” Set current time & date.
1111CLK”yy/mm/dd,hh:mm”? Set current time & date and send a conrmation text back to the sender.
Example: Setting the current time & date to 10:05am, 18th April 2016, the following text can be sent to the GSM intercom:
1111CLK”16/04/18,10:05”?
The GSM intercom will reply with the following text:
CLK = 16/04/18, 10.05

CHECK INPUT STATUS CHK
IMPORTANT NOTE: This feature is only applicable when auxiliary output AO1 mode has been set to mode 02. If auxiliary output
AO1 is set to any other mode then this feature will not work (also refer to Fig.28 on page 24 and setting auxiliary output AO1
mode, A1M, on pages 43 - 44).
If auxiliary output AO1 (A1M) mode has been set to mode 02 then the status of this mode can be checked by sending the following
text to the GSM intercom.
1111CHK? Check the current status of auxiliary output AO1 and send a conrmation text back to the sender.
Example: Check the current status of auxiliary output AO1, the following text can be sent to the GSM intercom:
1111CHK?
The GSM intercom will reply with either of the following texts:
IN = OP
VIDEX 4G
or
IN = CL
VIDEX 4G
(status open)
(status closed)
SILENT DIALLING MODE AUE
When the GSM intercom is calling the telephone number stored there is a choice of either hearing the ringing noise from the
intercom panel or just hearing beeps to indicate a call is in progress.
• Ringing heard during calling: nn = 01
• Beeps heard during calling: nn = 00
The following texts can be sent to the GSM intercom to enable (00), disable (01) or query the setting of the silent dialling feature.
1111AUEnn Set the silent dialling mode nn: 01 or 00.
1111AUEnn? Set the silent dialling mode nn: 01 or 00 and send a conrmation text back to the sender.
1111AUE? Query the current mode stored. A text message will be sent back to the sender conrming which
silent dialling mode has been set.
SEND DTMF TONE AFTER CALL ANSWERED FOR CALL BUTTON 1DTP, DTD AND DTT
It is possible to set the GSM intercom to send a DTMF tone after a call is answered. This option is only available for both the primary
number of button 1 and the divert 1 number for button 1. This feature is useful if the intercom is dialling into a telephone system
where an automated menu is present and a DTMF tone is required to select a particular option from the menu. This feature is
disabled by default. The following programming text messages allow the user to setup the DTMF tone(s) required.
