CONFIGURATION FILE
The configuration file «conf.txt» gives access to all the product settings with a list of parameters using the format :
CODE;PARAMETER_NAME;VALUE;
The format of each line is important and omitting a semi-colon leads to an error on this parameter.
The code is essential to identify the parameter and this number must not be modified.
The parameter name is optional and can be modified by the user but it cannot be empty.
The parameter value must take one of the possible values. For each parameter, the list of values is described in this doc-
ument, but also in the «conf.txt» file itself, in parenthesis at the end of each line.
If an error occurs in one of the parameters, the warning LED (red) lights up and an «error.txt» file, describing this error, is
created in the µSD card. The warning LED (red) also lights up if the µSD card is pulled off.
In case of any error on a parameter, of a missing µSD card or if the configuration file «conf.txt» is deleted, default values
are used.
These default values are also used for any missing parameter in the configuration file, but in this case no error will be dis-
played. This choice has been made to propose shorter and simpler configuration files, containing only a few parameters.
6.1 OPERATING MODES
The Maestro has one of 2 main operating modes, selected by using the following parameter :
• 100;MODE;1;
With the standard mode (1), used by default, you just need to dial the Maestro number to make an announcement from
any phone. To end the announcement and disconnect the communication, you can hang up the phone or remain silent.
If you hang up the phone, a few busy tones will be broadcast throughout the PA system (cf. §6.6).
In this mode, you can trigger any of the 6 input contacts to broadcast the matching pre-recorded message.
It is also possible to program the automatic broadcast of messages using a calendar (cf. §6.11).
The Maestro handles messages priority if another message is already in process (cf. §5).
The ambiance mode (2) broadcasts permanently the message held in the «Ambiance» folder.
In this mode, all other functionalities are disabled and no other broadcast is allowed.
In the standard mode, and only in this mode, the DTMF option can alter the main operating mode :
• 110;DTMF_OPTION;0;
By default, the DTMF option is disabled (0).
It the DTMF option is enabled (1), then the phone announcement process is altered as dialling the Maestro number does
not automatically start the communication with the PA system.
Indeed, once the product has picked up, it waits for a DTMF dial to decide which action to perform :
- dial «0» to start the communication with the PA system and make an announcement from any phone;
- dial «1» to «9» to broadcast a pre-recorded message, held in the matching folder.
You can trigger any of the 6 input contacts as in the standard mode and the message priority handling is extended to the
DTMF messages : a message triggered by one of the input contacts or a DTMF dial, and which has a higher priority level,
will stop any message in progress and will be broadcast instead (cf. §5).
It is also possible to program the automatic broadcast of messages using a calendar (cf. §6.11).
6.2 AMBIANCE MODE
In the ambiance mode (cf. §6.1), the Maestro broadcasts permanently the message held in the «Ambiance» folder.
In this mode, all other functionalities are disabled and no other broadcast is allowed.
• 113;VOLUME_AMBIANCE;0;
The ambiance message has a volume (0) by default. Value 0 is for the maximal volume and 80 for the minimal volume.
The audio output can also be tuned using the volume button (MES.) on the front panel.
•
114;RELAY_AMBIANCE;1;
During the broadcast of the ambiance message, it is possible to activate output relays.
By default, output relay R1 is activated (1) during the broadcast of the ambiance message.
It is possible to activate relay R2 (2) or both relays R1 and R2 (3). Relays can also be deactivated (0).
