4000 Series GSM Audio Intercom - Technical Manual
4000 Series GSM Audio Intercom with Proximity
The following commands are reserved for the technical department for interrorgating the GSM PRO module when testing and
applying specic additional features that are not covered in this technical manual. For the application of these commands please
contact Videx Technical on tel: 0191 224 3174 for UK based customers and Videx customer support on tel: +39 0734 631699 for
overseas customers.
PROGRAM BY ‘AT’ COMMANDS PRG
This is an advanced feature of the system which can allow an ‘AT’ format command to be sent to the OEM GSM module.
1111PRG(command) Send an ‘AT’ command to the OEM module.
AT COMMAND SEND AT START UP AT1, AT2 AND AT3
The AT commands AT1, AT2 and AT3 are advanced commands of the GSM PRO that allows additional features to be incorprated into
the module for testing purposes and include additional features for a specic application that is not already covered in this manual.
The following commands can be sent to the GSM module.
1111AT1”ATxxxxxx”? Include any AT command for AT1.
1111AT2”ATxxxxxx”? Include any AT command for AT2.
1111AT3”ATxxxxxx”? Include any AT command for AT3.
ENABLE EXTENDED OUTPUT TIMES EXO
The extended output time feature EXO allows the existing output time of the GSM PRO’s relay (RLT) and two auxiliary outputs (A1T
and A2T) to be increased for every second programmed to be extended to 1 minute. For example if the relay time RLT was set to 5
seconds and the extended output feature was enabled then the relay time would become 5 minutes.
There are 7 set extended output codes, from 81 to 87, that can be used. When one of these codes is used (refer to the EXO code table
below) it will allow one or a combination of the outputs to have an extended output time. For example if code 83 was used then
both the relay and auxiliary output 1 will have the extended output time feature enabled. So whatever the programmed relay time
RLT and auxiliary output 1 time A1T are set to the time will be in minutes and not seconds and this will be the time the respective
output will activate for. In this example auxiliary output 2 time A2T would still be set in seconds.
EXO code Output(s) EXO code Output(s) EXO code Output(s)
81 Relay 82 AO1 83 Relay and AO1
84 AO2 85 Relay ans AO2 86 AO1 and AO2
87 Relay, AO1 and AO2 32 disabled (default)
By default this feature is disabled (set to code 32). The following texts can be used to set the extended output time.
1111EXOnn Enable the extended output time for the required output(s) using EXO code nn, where
nn = 81 - 87 (refer to EXO code table).
1111EXOnn? As above and also send a conrmation text back to the sender of EXO code.
1111EXO? Query the stored EXO code.
Example: To enable the extended output time of the GSM PRO’s relay to 5 minutes and auxiliary output 2 to 10 minutes, the
GSM’s relay time RLT must rst be set to 5 seconds using the 1111RLT05 command and auxiliary output 2 (AO2)
must rst be set to 10 seconds using the 1111A2T10 command. Then the following text message can then be sent
to the GSM PRO intercom:
1111EXO85?
Including a ? at the end of the programming command the GSM PRO intercom will reply with the following text:
EXO = 85
OK VIDEX GSM
In the example the extended output time for both the relay and auxiliary output 2 (AO2) has been enabled. Since the
original relay time RLT has been set to 05 and the original auxiliary output 2 (AO2) has been set to 10, when either of
these two outputs are triggered the relay time will activate for 5 minutes instead of 5 seconds and auxiliary output 2
(AO2) will activate for 10 minutes instead of 10 seconds. As code 85 was used auxiliary output 1 time (A1T) will still
only operate in seconds (whatever the A1T has been set to).
IMPORTANT NOTE: When the extended output time feature is enabled the respective output is still triggered in the same way
i.e. the relay can still be triggered by pressing 3 on the phone during a call, triggered remotely by sending the text 1111RLY or
if any dial to open numbers have been stored activated when a DTO number dials into the GSM PRO intercom.
