Programming the GSM Intercom
CHANGE THE FOUR DIGIT CODE (CDE)
The four digit code can be any combination of numbers between 0-9 but must be 4 digits long. The code allows access to the
programming menu in dial in mode and must be used when sending text messages to the GSM intercom panel. Use the following
message to change the code.
1111CDEnnnn
Change the 4 digit code to nnnn (where nnnn = new 4 digit code).
TRIGGER THE RELAY (RLY)
There are several ways to trigger the GSM PRO 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 GSM relay (for the programmed time).
1111RLY?
Operate the GSM relay (for the programmed time) and send a confirmation text back to
the sender.
TRIGGER AUXILIARY OUTPUT AO1 (A1O)
It is possible to trigger the auxiliary output AO1 for the programmed AO1 output time (please note that this method of triggering
auxiliary output AO1 is only possible when the
A1M
mode has been set to mode 01, refer to page 35 and the example on page
21). This can be done by shorting terminals g & 5 on the GSM PRO intercom, pressing button 6 on the telephone during a call or by
sending the following message to the GSM intercom.
1111A1O
Trigger auxiliary output AO1 (for the programmed time).
1111A1O?
Trigger auxiliary output AO1 (for the programmed time) and send a confirmation text
back to the sender.
TRIGGER AUXILIARY OUTPUT AO2 (A2O)
It is possible to trigger the auxiliary output AO2 for the programmed AO2 output time (refer to page 35). This can be done by
sending the following message to the GSM intercom.
1111A2O
Trigger auxiliary output AO2 (for the programmed time).
1111A2O?
Trigger auxiliary output AO2 (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. Because the 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 GSM PRO intercom will reply with the current
balance stored on the SIM card.
1111BAL?
Check current balance of the SIM in the GSM PRO intercom and send a confirmation text
back to the sender.
In addition to this feature the GSM PRO intercom also has the facility to monitor the available credit and then text the user to inform
them when the credit has fallen below £5.00, €5.00 or $5.00. It will then remind the user with another text after every 5 calls until
the credit has either increased or if it runs out.
To use this feature, the following settings must first be made:
A Pay As You Go SIM card from a provider that offers this service (Vodafone, O2) must be used.
