02Technical Specifications

The Papağan is a compact, intelligent audio module with a CANBUS communication infrastructure, capable of managing audio files from an external memory card.

Thanks to the SD card slot on the device, audio content can easily be uploaded, updated and managed through external storage. Supported audio files are played by the built-in playback system and delivered as voice notifications through the external speaker output.

The product can operate in integration with different control units over CANBUS communication. In this way, specific audio recordings can be triggered by predefined commands.

With its compact dimensions, mounting holes for secure installation and robust enclosure design, it ensures safe operation in confined spaces.

How to read the CANBUS LED

Blinking irregularly

There is no current data exchange, or communication has not been established.

Blinking steadily

The device is actively operating and data communication over CANBUS is working.

04Mounting Dimensions

The Papağan device is designed with compact dimensions and standard mounting holes to make installation easy in field applications.

MOUNTINGRequirements

The mounting holes are 4 mm in diameter; fix the device to the surface with suitable screws and fastening elements.
Place the device on a stable, flat and vibration-free surface.
After installation, position the cables neatly and without tension.
Leave sufficient space around the device for maintenance and servicing.

05SD Card Structure

All the audio files the system needs are stored on the SD card. Its contents are organised into a specific folder structure, and the device operates based on that structure.

SD card
├── ARABIC/     language folder
│   ├── FLOOR/  floor and door announcements
│   └── INFO/   informational and warning announcements
├── FARSI/
├── FRENCH/
├── RUSSIAN/
├── SPANISH/
├── TR/
├── 1/          active usage folder — the device reads only this one
└── PL/         music files

Language folders

Folders in the root directory such as ARABIC, FARSI, FRENCH, RUSSIAN, SPANISH and TR contain the announcement audio for different languages. Each language folder is divided into two subfolders:

Subfolder	Contents
`FLOOR`	Floor and door announcements — for example floor information, door opening direction
`INFO`	Informational and warning announcements — for example "door opening", "emergency"

Screenshot showing the contents of the SPANISH language folder — Image 3 — Contents of a language folder

Active usage folder — `1`

The 1 folder on the SD card is the folder the system actively uses. While the device is running, it reads only the audio files in this folder.

Music folder — `PL`

The PL folder holds the music files. Music files and announcement files are kept separate, and the system operates with that distinction in mind.

General operating logic

Folder	Role
Language folders	Predefined announcement archive
`1`	Announcements actively in use
`PL`	Music files

Requirements

All audio files must be in a format supported by the system — WAV.
The file naming convention must be followed.
The SD card structure must not be modified and folder names must be preserved.
Safely removing the card after copying files is recommended.

06Changing the Announcement Language

You do not need to make a separate setting to change the language of the device — copying folders is enough.

STEP 1Pick the language

Open the folder of the language you want the announcements in on the SD card (for example TR or SPANISH).

STEP 2Copy

Copy the FLOOR and INFO contents from that language folder into the 1 folder.

STEP 3Eject the card safely

When copying is finished, eject the card safely and insert it into the device. The device will now play the announcements in the new language.

07What PapaganApp Is

The Papağan Audio Management Application is a desktop application developed for organising and managing the audio files on the SD card.

With the application you can:

add audio files to the library,
delete files,
view file information,
convert MP3 files to WAV format,
save converted files to different folders.

The application consists of two main screens.

08Main Screen

The main screen is the primary control panel of the application. All operations are started from this screen.

Audio library

The audio library is the section where all audio files added to the application are listed, and it is on the left side of the main screen. It represents the Lib folder inside the application directory.

Lists all audio files in the Lib folder.
Supports .mp3 and .wav file formats.
Long file names are automatically shortened for display.
Details of the selected file are shown in the right panel.
Converted files are marked in the list.

To add audio files to the list, use the Add Audio File button or drag and drop the files directly.

File details

This panel is on the right side of the main screen and its information is updated instantly for the selected file. When no file is selected, the area remains empty.

Field	Information shown
File name	Name of the selected audio file
File path	Folder path where the file is located. After conversion it shows the target folder.
File format	`.mp3` or `.wav`
File size	Size of the file on disk
File duration	Total duration of the audio file, in minutes and seconds
Sample rate	Sampling frequency in Hz — for example 44100 Hz
Channels	Mono or stereo
Bit	Bit rate or bit depth

Adding, deleting and editing files

#	Operation	How it is done
01	File adding	One or more files can be selected from the computer with the Add Audio File button. Drag and drop can also be used.
02	File deletion	The file selected in the list is removed from the `Lib` folder with the Delete Audio File button. Confirmation is required before deletion.
03	File editing	The selected file is transferred to the editing screen with the Edit button.

Delete and Edit operations cannot be started without selecting a file.

09Editing Screen

This is where the conversion and renaming operations for the audio file selected on the main screen are performed.

PapaganApp editing screen — file name, format, target folder and save fields — Editing screen

#	Field	Description
01	File name	Shows the name of the selected file according to the naming rules. A new name can be entered.
02	Format	The format the file will be converted to. `.wav` by default.
03	Target folder	Where the converted file will be saved. Set with the Select Folder button.
04	Save	Starts the conversion with the chosen settings. Progress is shown on the progress bar.

File name editing

By default the name of the selected file is adjusted according to these rules:

a maximum of 10 characters,
Turkish characters converted to their English equivalents,
spaces replaced with underscores (_).

Format selection

The selected audio file is converted to .wav format; this option is set by default.

The source file must be MP3

The selected file must be in .mp3 format. Otherwise the application returns an error when the file is added to the audio library.

Target folder selection

This sets where the .wav file will be saved after conversion. The converted file does not appear in the Audio Library — only the location of the converted file changes, while the files in the Lib folder remain unchanged.

Conversion process

Once the required settings are configured, pressing Save starts the conversion. When it is complete, the converted file is copied to the target folder and a check mark (✓) appears next to the file in the Audio Library.
