1Introduction
1.1 What is DINplayer?
DINplayer is an advanced MP3 player with solid state memory, which has been designed
to play warning messages, voice alerts and all types of audio files, recalled by the use of
logical inputs in binary combination.
Standard DIN clamp housing allows to use it with different automation systems: PLC,
industrial computers, touch screen operated terminals, automatic distributors, commercial
promotion systems and various uses on switchboards.
1.2 What is Mp3?
Mp3 is an acronym for Mpeg-1 layer 3. This is an audio compression standard which
eliminates sounds which the human ear cannot hear via a psycho-acoustic algorithm. The
purpose of this compression is to reduce the space taken up by an audio file while still
ensuring excellent quality. The greater the compression, the less the audio quality. The
right compromise, which guarantees a quality comparable to that of a Compact Disc, is
128 Kbps (thousands of bits per second) which represents the most widely used manner,
and reduces the size of an uncompressed file by 10 times.
1.3 Encoder
Software which compresses audio CDs or wave files into MP3s. There are many software
of this kind, and it is virtually impossible to say which is the best.
1.4 Decoder
Software which decompresses an MP3 audio file in order to send it to a digital-analog
converter and reconstruct the original audio signal.
1.5 Player
Hardware and software system able to read MP3 audio files. DINplayer is able to carry out
this function.
1.6 Wave
High quality audio format (extension .wav), compatible with the tracks of normal music
CD’s. If one uses a wave file in format 44.1 KHz/sec. at 16 bit in stereo, one will get
exactly the same quality as a music CD, but the size of the file is about 10Mb per minute.
1.7 Audio compression in various formats.
The following graphic shows the space taken up by an uncompressed audio file of about 5
minutes (.wav) and compressed in MP3 at 128Kbps (MP3).
Wave 51,1 MB
MP3 4,6 MB

3.3 Power supply
DINplayer may operate with the following voltage power supplies: 12÷24VDC.
In the case of configuration with power amplifier, the use of a suitable power supply is
recommended to supply the required audio power . With a 4Ωloudspeaker, DINplayer can
absorb current peaks of 2A.
The standby consumption is 1W.
3.4 Vplay output for external relay
The output of the DINplayer is of a transistor type and is
optoisolated towards the inside CPU.
When activated, it provides on the output terminal the
same feeding voltage applied on the module. This voltage
may be applied to the input of a PLC or else it may
directly pilot the spool of an outside relay.
The output can provide a maximum current of 150mA and
is equipped with a protection diode for inverse currents
induced by the spool of any outside relay.
The output is activated at the time when the reproduction
of an audio file starts, and is maintained in this state
throughout the duration of the file.

3.5 DINplayer Configurations
DINplayer in addition to the 6 logic inputs for the audio files activation has a mono 20W
amplifier to directly drive an external loudspeaker and it can be connected through the
serial port to an RS485 bus, to be controlled by a master system or by a computer.
To configure the device to meet your needs, gently use a screwdriver to lift the clamps
cover and to move the P1, P2, P3, P4 jumpers as displayed below.
1. DINplayer with 6 logical inputs and preamplified STEREO output.
In the "factory default configuration" the logical inputs mode is active and the power
amplifier is NOT active.

3.6 Logical inputs
DINplayer has six optoisolated logical inputs, to trigger the audio files. To activate an input,
apply a tension between 12 and 24Vdc to the Common inputs pin and the desired logical
input.
Using the binary combination of logical inputs, it is possible to activate a maximum of 63
audio files (see table 5.2).
The positive pole can be indifferently connected to the common inputs or to the logical input.
Logical input connected to ground (GND)
and external power supply:
connect Common input (pin 1) to a tension
between
12 and 24Vdc. To activate the
input connect it to power supply ground.
Logical input connected to external
power supply (12-24Vdc):
connect Common input (pin 1) to the power
supply ground. To activate the input connect
it to the power supply positive.

4Configuration file
4.1 What is the configuration file?
DINplayer is a very versatile device which can be adapted to the needs of the application
in which it is used. Different applications may require adjustment of volume, tone,
loudness, special parameters of communication or timing. The text file, called
‘configuration file’ and stored in the main directory of the flash memory, together with the
audio files, makes it possible to programme the various parameters of DINplayer.
This file must be assigned the name config.txt (this extension has been used so it can be
modified by any text editor, including those for portable PocketPC terminals).
4.2 Content of the configuration file
Each line of the configuration file consists of:
Mnemonic code of the parameter to be set. It always consists of four CAPITAL
alphanumeric characters, and must always be at the beginning of the line. No more
than one parameter is permitted on the same line.
Separating character. ‘=’.ThisMUST be inserted just after the mnemonic code, without
any spacing or tabulation character.
The relevant numerical parameter expressed as a decimal, to be inserted directly after
the separation character, without any spacing or tabulation character.
Example file config.txt:
LOUT=14
LLOU=10
LTRE=14
LBAS=10
Audio adjustment parameters
TPCM=10
MICP=1
MIRS=1
Logical inputs parameters (direct or binary combinaton)

CMBR=3
CMPR=0
CMSB=1
CMDB=8
CMDR=0
CMNR=0
RS485 serial port communication parameters

DINplayer User Manual v.2.3
Page 16
4.3 How it is managed by DINplayer
At the time the device is turned on, or when the flash memory is inserted, DINplayer will
start to read the main directory of the memory; once it has found the file config.txt,it
interprets the parameters inserted in each line, memorising them permanently in its
internal memory, of a non volatile kind. The parameters therefore stay in memory even
after the device has been turned off. This is why it is not indispensable for the
configuration file to be always present in the flash memory: once all the parameters have
been acquired, this file can also be deleted.
NOTE: If it is necessary to configure various DINplayers with the same parameters, one
can prepare a single flash memory with the appropriate config.txt file, alternately insert this
memory on all the modules to be configured, then insert the memory with the audio files
only.
4.4 Preparing the file
To create the file, one can use an ordinary text editor (like Windows Notebook). The file
must be saved as a pure text file (.txt). Should other programmes be used (e.g. Microsoft
Word) one must be careful to save the document as “text only”: otherwise, control
characters would be inserted which would make it impossible for DINplayer to interpret this
file.
4.5 Memorising the files in the flash memory
The configuration file and all the MP3 audio files can be memorised in the flash memory
via a special USB reader/writer for PC.

DINplayer User Manual v.2.3
Page 17
4.6 Audio adjustment parameters
DINplayer allows for the following audio adjustments:
adjustments general amplified/pre-amplified output.
adjustment of loudness level.
adjustment of high tone level.
adjustment of low tone level.
The following tables show the relation between the value set in the configuration file and
the actual value of the audio parameter.
