CHANGE THE 4 DIGIT MASTER CODE (CDE)
The four digit master code (by default = 1111) can be any combination of numbers between 0 - 9, but must be 4 digits long. The
code allows access to the full programming menu and must be used when sending text messages to the digital GSM. Use the
following message to change the four digit master code (also see notes on page 41).
1111CDEnnnn
Change the 4 digit master code to nnnn (where nnnn = new 4 digit master code).
CHANGE THE 4 DIGIT ADMIN CODE (CDA)
The four digit admin code (by default = 0000) can be any combination of numbers between 0 - 9, but must be 4 digits long. The code
allows access to the admin menu and must be used when sending text messages to the digital GSM. Use the following message to
change the four digit admin code (also see notes on page 42).
1111CDAnnnn
Change the 4 digit admin code to nnnn (where nnnn = new 4 digit admin code).
CHANGE THE 4 DIGIT TRADE CODE (CDT)
The four digit trade code (by default = 2222) can be any combination of numbers between 0 - 9, but must be 4 digits long. The trade
code can only be used when a timeclock has been connected to the trade input (TRD terminal) on the digital GSM when a trade
code facility is required. Use the following message to change the four digit trade code (also see notes on page 42).
1111CDTnnnn
Change the 4 digit trade code to nnnn (where nnnn = new 4 digit trade code).
TRIGGER THE RELAY (RLY)
There are several ways to trigger the digital GSM relay. The first is to press button 3 on the telephone during a call and the relay will
operate for the programmed time. Another way is to send the following text message.
1111RLY
Operate the digital GSM relay (for the programmed time).
1111RLY?
Operate the digital GSM relay (for the programmed time) and send a confirmation text
back to the sender.
TRIGGER AUXILIARY OUTPUT AO (A1O)
It is possible to trigger the auxiliary output AO for the programmed output time (
A1T
, also refer to page 43 for setting A1T time).
Please note that this method of triggering auxiliary output AO is only possible when the
A1M
mode has been set to mode 001, also
refer to page 39 and the examples on pages 13 and 14. Triggering the auxiliary output can be achieved by shorting terminals AI
and GND on the digital GSM intercom, pressing button 6 on the telephone during a call or by sending the following text message
to the digital GSM panel.
1111A1O
Trigger auxiliary output AO (for the programmed time).
1111A1O?
Trigger auxiliary output AO (for the programmed time) and send a confirmation text back
to the sender.
STORE BALANCE CHECK DIAL STRING (SDL)
Several network providers offer the facility to check available balance on their pay as you go tariffs. For example, on Vodafone the
string is *#1345# and on O2 the string is *#10#. Other networks may also have this feature. Since the digital GSM intercom will not
know the details of the network provider’s SIM card which you have inserted it will be necessary to store the correct string in order
to use the credit balance check features.
1111SDL”*#1345#”
Store the balance check string for a Vodafone pay as you go.
1111SDL”*#10#”
Store the balance check string for an O
2
pay as you go.
IMPORTANT NOTE: Videx are only aware of the balance check dial string codes for the network providers mentioned above.
Check dial string codes for other networks are currently unavailable at this time. Please also note that this programming
function is only applicable for pay as you go SIM cards.
CHECK CREDIT BALANCE (BAL)
The balance can only be checked if the correct balance check string has previously been stored using the
SDL
code explained
above. At any point the user will be able to send the following text message and the digital GSM intercom will reply with the current
balance stored on the SIM card.
1111BAL?
Check current balance of the SIM in the digital GSM intercom and send a confirmation
text back to the sender.
