1 - Présentation

MicroPlayer MKII reads WAV and MP3 audio files. This standalone player can read files automatically
according to a broadcast schedule or upon triggering by external events (input dry contact, RS232,…).
Files are stored on a SD/SDHC memory card or on a USB flash drive.
MicroPlayer MKII broadcasts music, sounds or messages in many environments like museums,
showrooms, shop windows, attractions,touristic places, exhibitions..

2 - Functionalities

Interactivity: MicroPlayerMKII is an interactive player that reacts depending on events.

- Playback pattern is defined by the name of files or folders

- Electrical contacts: 4 inputs combinable up to 15 inputs to trigger files through sensors, push­buttons,relays …

- 2 outputs can control Leds, relays, motors or any other external equipment thanks to Mosfet up to
500mA switch.

- Commands through the RS232 serial link. A simple protocol is used to send instructions to the player.

- Infrared sensor allows the use of a remote control.

Autoplay: MicroPlayer MKII starts automatically on powering on. This function is configurable and can
be disabled.

Playback: The audio files stored on a SD/SDHC memory card - USB flash drive can be organized in a
particular way to define playback pattern. The playback pattern is defined by the names of the files and
the folders, allowing a wide flexibility of use.

Audio output: 2 types of output are proposed.

- A line level stereo audio output on a RCA standard connector

- An amplified stereo output on a removable terminal block (RTB).
Power supply: A 12v external power supply is required.

The player is protected against polarity reversals and against usage, by mistake, of an alternative power
supply instead of the D.C. power supply provided.
Caution! The player can accept a tolerance of the power supply voltage between 10 & 15V. Apart from
this voltage range, the player can be damaged.
The input supply is transferred to the RS232 connector and the output terminal (RTB) to supply the
connected accessories.

The power of the PSU determines the output power of the amplifier. When a line level output is used , a
500mA (6w) power supply is adequate to run on the player. When the amplified output is used for large
powers, a supply of at least 3,45A(45w) is obligatory. If you use a PSU of an inferior power, you can
have a very poor sound and also a overheating PSU till broken down.

Serial link RS232: MicroPlayer MKII can be controlled by a PLC, a computer, a remote control using a
serial link. MicroPlayer MKII receives data on its Rx input and sends datas on its Tx output. A specific
protocol is described in this manual.

2 - Connect speakers or a sound system to the audio output and switch on the player thanks to the PSU

Power Supply Unit: We recommend you to use the PSU provided with the player. If you use another
PSU or a battery, you have to respect the 12V specified voltage although the player can be power
supplied between 10V and 15V. The power consumed depends on the power level of the amplifier.

Preparation of the medias:

Brand new SD/SDHC memory card and USB flash drive are usually "FAT" or "FAT32" formatted.
If you must format a card or a stick, select the FAT or FAT32 format depending on memory size. (FAT32
above 512Mb).Other types of formatting do not work.

If you use Windows PC computer, latest versions do not allow to format high capacity medias(>32Go)
system FAT. In this case you must obtain a formatting software. Many software are available , some free,
others paying that you will easily find on internet.

4 - Operating mode

Compatibles files:

.MP3: audio files MP3 format ( see annex C)
.WAV: audio filesWav format ( see annex C)

The file and folders names define the playback mode. The files and folders must be stored and copied
according to a specific organisation described below.

4.1 Organisation of the folders:

Only ONE folder level is allowed at the root. The folder names
are composed of 3 digits (000 to 999) followed by optional
parameters and the name of your choice.
You should not use special or accentuated characters
.
Example :
001
003 [J002]
034 folder name
247 [V+02] [SEQ] my folder

●●

●●

● The first three digits represent the folder No and therefore its main name

Folders are numbered from 000 to 999.
Example :

000 : Folder N°000 - "Autoplay" folder which is automatically played when the device is powered on.
001 : Folder N° 1
034 : Folder N° 34

The folder number is used to define the playback order, it identifies the folder to use during a jump or an
input triggering. You can use any number between 000 & 999.

IMPORTANT : The 4 input contacts allow the triggering of the folders numbers corresponding to these
3 digits, as per a binary order from 001 to 015. It is possible to modify the numbers of the triggered folders
by editing file config.txt. (See chapter 5).

Folder 001- > Input 1
Folder 002 - >Input 2
Folder 003- > Input 1+2
Folder 004- > Input 3
Folder 005- > Input 1+3

Special case: Folder 000 is the folder which will be played by default when powering on. When
powering on, presence of this folder is checked ; if it is present, the player plays files of this folder.
If this folder is missing, the player turns in to sleep mode.

Note: The folder which is read by default when powering on can be modified in the configuration
menu.

Additional Parameters - Optional Tags:

To modify the conduct of the player, you can add optional parameters within the folder name. These
parameters are boxed with the symbols "[" "]". You can add several parameters within the folder
name.

[Jxxx] - Jump to another folder after reading the current folder.
[RET] - Returns to the previous folder after reading the current folder.
[RND] ou [SEQ] - Specifies random or sequential playback mode for the current folder.
[RLxy] - Activate the output contacts
[V+xx] ou [V-xx] - Controls the volume level of the folder
[NT] Or [DT] – Define interruption modes
[RSxxx] – Sending of RS232 codes

Note: If no optional parameter has been indicated, the player reads randomly the folder in full and
then stops. The folder can be intterupted

●●

●●

● [Jxxx] – Assign the folder No. to read after the reading the current folder.

By adding this parameter within the name of the folder, you define the conduct of the
player after reading the current folder so that it starts reading another folder for example. This option
is also used to read a folder in a loop mode .
Example:
001 [J002]: Jump to folder 002 after reading folder 001
003 [J003]: Jump to folder 003 after reading folder 003-> create a loop of the 003 folder
008 [J023]: Jump to folder 023 after reading 008
458[J999] : Jump to folder 999 after reading folder 458

To play loop files on powering on, you will use the folder 000 and the tag [J000] ( value by default that
can be modifiable through config file )
Exampe:
000[000]

●●

●●

● [RET] - Returns to the previously read folder after reading the current folder.

You are reading a folder. A command arrives in order to read another folder having [RET] tag. The
player jumps in the new folder, reads the content of this new folder and once all files are read the
player goes back to the reading of the previous folder. You can use this function to broadcast a same
message after the reading of folders.

Several different folders can appoint a same folder in order to come back to the folder that has called him.
Example:

001 [J100]: After reading folder 001, jumps to folder 100
002 [J100]: After reading folder 002, jumps to folder 100
100 [RET]:After reading folder 100, returns to the previous folder (001 or 002)

® Waves System V 1.0 - 2013

I.D. AL - MicroPlayer mkII - Wav MP3 Audio player - User manual

- 1 1 -

In the above example, after reading folders 001, 002, a jump to folder 100 is made to read the content.
After reading folder 100, the reading occurs in the previous folder, it has to say the folder recently
called.

●●

●●

● [SEQ] or [RND] - Specifies sequential playback mode of the current folder. By default or without

parameter, the folder is read in a random mode.
[SEQ]: reading in a numerical order
[RND] or without any parameter : reading in a random mode

Example:
001 [SEQ]: read folder 001 in a sequential numerical order and stop at the end of the folder.
002[RND][J002]: reading of the folder 002 in a random mode or in a loop.
003[J001]: reading of the folder 003 in a random mode then jump to folder 001.

By choosing [SEQ] you select the sequential mode, meaning a reading in a defined order. The sorting
is made through a numerical order it has to say in the order of the numeros of the names of the files
(see next chapter related to files organisation within the folders for the naming details).
In a defined order [SEQ], the files which are not numbered are ignored.
The folders which do not comply with the naming rules are ignored.

By default, if optional parameter is not present, the reading is made in a random mode.

●●

●●

● [[RLxy] - Enable or disable the 2 outptut contacts

Each folder can directly activate different output contacts without any additional programming. You
can switch on a light, motors or any other actions depending on the folder read.

[RLxy]: x,y represent the 2 outputs (x=output 1 – y= output2) and can accept 3 values
x or y = 0 : outputs are disabled

x or y = 1 : outputs are enabled during the reading of the current folder
x or y = 2 : outputs are permanently activated. An order is necessary to inactivate outputs.

Example :
000[RL00][J000]: the folder 000 is read in a loop on powering on. Outputs are disabled.
001[RL10][J000] : enable output 1 when the reading of the folder 001 occurs then go back to folder 000
with disabling output 1 after reading folder 001.
002[RL02][J003] : enable pemanently the output 2 during the reading of the folder 002 then jump to
folder 003 without disable the output 2.
003[J003] :

Output contacts are switched from the beginning of the reading of the folder. If the files within the
directory have an activation or inactivation option of the outputs contact, the different outputs will
evolve.

●●

●●

● [V+xx] ou [V-xx] – Volume setting

The name of the folder can act on the output volume. This function is used to broadcast messages
loud more or less than others files.
Example :
001[V+05]: increase the volume level from 5 steps during the folder
001[V-03] : decrease the volume level form 3 steps during the folder

® Waves System V 1.0 - 2013

I.D. AL - MicroPlayer mkII - Wav MP3 Audio player - User manual

- 12 -

At the end of the reading of the folder, the volume level goes back to its previous level.

- If the variation values exceed the minimum or maximum values of the player, the levels are settled to
their maximum or minimum.

- If the volume level is yet to its maximum or minimum, the instruction is ignored.

●●

●●

● [NT] or [DT] - This option defines the interruption mode of the folder currently read.

If these options are registered in the folder name, the read file cannot be interrupted and instructions
received are ignored or executed at the end of the file.

Without this option, the reading of the currently read directory can be interrupted at any
time by an external action. (input, Ethernet, RS232 ...)

Example:
001 [NT] - The folder can NOT be interrupted.
In that case, an action on one of the input contacts through RS232 or other is ignored and the reading
of the current file is not stopped. Caution! The action is not memorised and the triggering information is
lost.

001 [DT] - Interruption instruction is memorised and will be executed at the end of the folder.
An action on one of the input contacts through RS232 link is memorised but the reading of the current
file is not stopped. Caution! If several actions occur while reading the file, the history of actions is not
memorised and triggering information is lost. Only the lastest action is memorised and executed.

●●

●●

● [RSxxx] – This tag allows to send octets onto the RS232 output.

When the folder is called, a list of bytes is transferred by the serial link in order to control other devices
( another player, switching grid, projector, ..)
The bytes to send are included in a text file that will be especially created for.
Value by default : 19200 Bauds ( modifiable through the setup file ) - 8 bits – no parity – 1 bit start – 1
bit stop
[RSxxx]: xxx appoint the number of the line of the file serial.txt that must be sent ( value from 001 up
to 999)
The file definition of the bytes to send must be named : serial.txt
This file will be copied at the root of the media ( memory card/flash drive)

This file is a text file (raw text without page setting ) that can be created with any easy text editor like
« notepad « from windows or similar. When recording, use «ANSI» coding . Do not use special
characters.

The file «serial.text» of RS232 codes is a text file containing one or several lines. Each of these lines
will include a sequence of bytes expressed in hexadecimal and separated by a space ( from 00h to
FFh). You must only indicate the two characters of the wished hexadecimal value.

Each beginning of line of this file should present the following parameter:
# xxx : the xxx number of the line containing the bytes to send related to the xxx of the tag.
[RS002]-> line # 002 – the tag [RS002] will send the sequence of bytes of the line

# 002 of the serial.txt file.
The separator between each byte is a space.

●●

●●

● Specific conduct:

-If a folder is missing but a command designates this folder, the command is ignored.

-When triggering designating a folder that does not contain a file and if a name contains an optional
tag, this option is executed. If no playback option ( for example a jump )is indicated, the player turns into
stop mode.

® Waves System V 1.0 - 2013

I.D. AL - MicroPlayer mkII - Wav MP3 Audio player - User manual

4.2 Organisation of files inside folders.

Like for folders, files name define the playback conduct.

Note: The naming of the files is free if the reading is in
a random mode. («RND» option or no option in the
folder name). In this case, all the files will be read and
can be interrupted.

In a sequential mode, you should number the files.The
names are composed of 3 digits (000 to 999) and of a
name of your choice. Optional informations (tags) can
be added following your need, like the interruption of
the file or the triggering of the outputs.

Example:
001 [J367] my message.mp3
063 [R020] file name.wav
845 [V+12][RL01] my file.mp3"
MY SONG [NT].wav

Note: In sequential mode (SEQ), if numbered and non­numbered files are present, only the numbered files
will be read. In random mode, all the files be read.

●●

●●

● The first three digits represent the file number and thus its principal name from 000 to

999.

Example:

001.mp3 - file No.001

063.wav - file No.063
If the folder indicates random mode [RND], the files don’t have to be numbered and playback will be in

random mode. In sequential mode [SEQ], file are read in the first three digits order and the non­numbered files are ignored.

Optional parameters

T o modify the conduct of the player , you can add optional parameters in the file name. These parameters
are boxed by the symbols «[« and «]». You can use several parameters in the file name.

[Jxxx] - Jump to a folder after reading the current file.
[NT] or [DT] - The file can not be interrupted or the action is memorised to be executed at the end of

the file.

[RLxy] – Enables or disables output contacts
[RSxxx] – Sending of a sequence of bytes through RS232 link

Note: Without any option, the files are read the ones after the others according to the selected mode
(random or sequential) and can be interrupted at any time by external action.

● [Jxxx] designates the folder number to use after reading the current file.

By adding this parameter within the file name, you define the conduct of the player at the end of the
reading of the current file in order to read another file.
If the destination folder does not exist, the action is ignored.
If the destination folder do not have any file , the player turns into stop mode.
Example:
My file [J002].mp3 - Jumps to folder 002 after reading file.
003 [J023][RL02].mp3 - Jumps to folder 023 after reading file 003 and enable output2.
034 [J034].wav - Jumps to folder 034 after reading the file. It’s not a loop with the file 034 but a jump
to folder 034.

This function allows for example to survey a file in order that he is followed by a Jump.
Several files can designate the same directory of jump.
Example :
001[J100].mp3 – after the reading of the file 001, Jump into folder 100
002[J100].wav – After the reading of the file 002, Jump into the folder 100

●●

●●

● [RLxy] enables or disables the 2 output contacts

Each file can activate output contacts directly without any additional programming.
You can switch on lights, run a motor or any other action according to the files read.
[RLxy]:x,y represent the 2 outputs (x= output 1 – y = output 2) and can be from 3 values

x or y = 0 : outputs are disabled
x or y = 1 : outputs are enabled all along the reading of the current file.
x or y = 2 : outputs are permanently enabled. Another instruction is needed to disable outputs.

Example :
My file [RL00].mp3 : read the mp3 file. Outputs are disabled
001[RL10].wav – Enable output 1 during the reading of the file 001.wav then go on the reading of the
following file with desactivating output 1.
Message[RL02].mp3 – Enable output 2 during the reading of the file then go on reading of the following
file without disabling output 2.
004[RL21].wav – Enable the two outputs during the reading of the file 004.wav then go on the reading
of the following file without disabling output 1 and with disabling output2.
Output contacts are switched at the beginning of the reading of the file and disabled at the end of the
file.

●●

●●

● [NT] or [DT] - This option defines the interruption mode of the file currently read .

If these options are registered in the file name, the file cannot be interrupted and instructions received
are ignored or executed at the end of the file.

Without this option, reading of the current file can be interrupted at any time by an external
action except if the option is included within the name of the file.

Example:
001 [NT].mp3 - The file can NOT be interrupted.

An action on one of the input contacts, through RS232 link or any other is ignored and the reading of
the current reading is not stopped. Caution! The action is not memorised and the triggering information
is lost.

001 [DT].mp3 - The instruction of interruption is memorised and will be executed at the end of the file.
An action on one of the input contacts, through RS232 link or any other is memorised and the reading
of the current file is not stopped. Caution! If several actions occur while reading the file, the history of
actions is not memorised and the triggering informations are lost. Only the last action is memorised and
executed.
The files that can be interrupted and those that can not be interrupted can coexist in the same folder.

● [RSxxx] – This tag allows to send bytes through RS232 output.

This tag allows to send bytes onto the RS232 output. When the file is called, a list of bytes is
transferred by the serial link in order to control other devices ( another player, switching grid, projector..)
The bytes to send are included in a text file that will be especially created for that purpose.
Value by default : 19200 Bauds ( modifiable through the setup file ) - 8 bits – no parity – 1 bit start – 1
bit stop

[RSxxx]: appoint the number of the line of the serial.txt file that must be sent (value from 001 up to 999)
The file definition of the bytes to send must be named : serial.txt

This file will be copied at the root of the media ( memory card/flash drive)
This file is a text file (raw text without page setting ) that can be created with any easy text editor like

« notepad « from windows or similar . On recording, use «ANSI» coding . Do not use special characters.
The file «serial.text» of RS232 codes is a text file containing one or several lines. Each of these lines

will include a sequence of bytes expressed in hexadecimal and separated by a space ( from 00h to
FFh). You must only indicate the two characters of the wished hexadecimal value.

Each beginning of line of this file should present the following parameter:
#xxx : xxx number of the line containing the bytes to send in connection with the xxx of the tag.
[RS002]-> line #002
The separator between each byte is a space.
Example of a line contained in the serial.txt file.

#001: 45 85 63 21 78 A5 B2
#002: 98 75 21 35 45 98
#100: 21 35 45 78 A5 B2

It is also possible to add comments within the file by using two times the type «/» (slash writer)
// example file

#001: 05 A1 FF E4 // comment in the line

5 - Setup file

Some functionalities are only accessible via a setup file. This file is a text file (raw text without page
setting ) that can be created with any easy text editor like « notepad « from windows or similar. On
recording, use «ANSI» coding . Do not use special characters.
This configuration file must be named : config.txt and have to be copied on SD memory card or USB
flash drive and located at the root of the media.
If this file is missing, the factory setting values will be implemented by default.

The configuration file allows to make the following settings:

5.1 - #ID:xxx – Assign a number to the MicroPlayer to use it with others players through RS232

5.2 - #VOLUME:xx – Define the output volume used on powering the player.

5.3 - #POWER:x – turn into «energy saving» mode when the player is not reading

5.4 - #BAUDRATE:xxxx – Modify the speed of the serial port RS232

5.5 - #RS_MONITORING:x – Configure the monitoring mode of the serial link RS232

5.6 - #BOOT:xxxfonction - Define the reading folder of the input contacts

5.7 - #INPUTxx:fonction – Configure functions of the input contacts

5.8 - #BUTTONx:fonction – Assign other functions to the 2 front buttons.

Note: The command layout is made of « # «symbol, followed of a key word, followed by « : « symbol
and at last the associated value. The commands can be entered in the order you wish. If a command
is missing , the player will use by default the factory settings.

5.1 - Assign a device number - #ID:xxx

It is possible to make several MicroPlayer MKII coexist in a same installation and to make them communicate
amongst themselves from a main device through RS232. For this a number is assigned to each
MicroPLayer mkII among the choice of 127, meaning that 127 MicroPlayer mkII can be use in the same time
( see chapter 6 ).
Command line :

#ID:xxx xxx a number between 001 and 127

Example:
#ID:023 Assign number 23 to the choosen player

If the line is missing , the factory setting value by default is used , it has to say 001 to assign player

001.

Note: several player can have the same number. All the player having the same number will react
same time.

000 is a particular case and should not be used. When code 000 is sent through serial link, it means that
all the players react on command sent in an overall way.

5.2 - Output volume setting - #VOLUME:xx

On powering , it is possible to set the output volume level. This volume can be modified by the front
buttons, RS232 or infrared remote control.
The volume setting goes from 00 to 64, it means 64 steps.
00 is minimum volume setting ( mute) and 64 is the maximum volume setting.

® Waves System V 1.0 - 2013

I.D. AL - MicroPlayer mkII - Wav MP3 Audio player - User manual

- 19 -

Command line:

#VOLUME:xx xx = a value between 00 and 64

Example :
#VOLUME:18 the volume will be from 18 on powering

If the line is missing the last known value by the player will be used.

5.3 - Energy saving mode ( stand by ) - #POWER:x

MicroPlayerMKII can turn into energy saving mode during its standby mode. It is possible to use a
battery as a power source. The player turns into this mode automatically when he does not read a file.
Only the input contacts are watched. When an input contact is detected, the player « wakes up» et
and executes the command.

Note: When the folders contain numerous files, the waking time is lenghtened.

Command line:

#POWER:x x = value 0 or1

0 = normal mode withon saving mode management

1 = energy saving mode
Example : #POWER:1 The player is in energy saving mode
If the line is missing, the factory setting value is used by default, it has to say 0, normal mode without

energy saving management.

5.4 Configuration of the speed of the RS232 - #BAUDRA TE:xxxx

By default, the serial link RS232 in and out is 19200 Bauds; With this option you can modify this value.

Command line:

#BAUDRA TE:xxxx x = a value among 9600, 19200, 38400

Example :
#BAUDRATE:9600 The player send and receive 9600 bauds.

If the line is missing, the factory setting by default is used it has to say 19200 bauds.

5.5 Monitoring of the player through RD232 - #RS_ MONITORING:x

The MicroPlayer MKII has one serial input and one serial output RS232 standard.
This link can be used to control the player but also to watch him.
Four configurations are possible to define the kind of outgoing link.

● Mode 0 : no monitoring , No data sent by the player

● Mode 1 : «Daisy Chain» mode

This mode allows to chain up the players the ones after the others with one only RS232 link. The serial
Tx output of a player is connected to a serial Tx input of the next one and so on. When the first player

® Waves System V 1.0 - 2013

- 20 -

receives an instruction, this same instruction is sent to its output and so on. Caution , when numerous
players are chained up a latente period can exist at the end of the chain.

● Mode 2: Monitoring mode

In this mode, the player send onto its Tx serial output, some information on its status.( see previous
chapter describing the procedure )
An external device can therefore receive informations to know if the player is in a reading mode or in a
stop mode. These functions can be used to check the good functioning of the player.

● Mode 3: Advanced monitoring mode

The advanced mode has the same functions that the standard monitoring mode and the additional
function is the regular sending of informations on its status. A frame is sent every 250 ms describing the
status of the player among 3 possibilities:

1 - Stop - send a frame indicating that the player does not read and wait for a command.
2 - Playback - send a frame indicating that the player reads a file
3 - Other -No frame sent : the player is not available. The memory card is missing or defective, power
supply default or the player is out of order.

This mode is used in a context of security message management. A frame fault reports an error and
allows to intervene to solve the default

Command line:

#RS_MONITORING:x x = a value 0,1, 2 or 3

0 = no monitoring
1 = "daisy chain" mode
2 = monitoring mode
3 = advanced monitoring mode

Example :
#RS_MONITORING:1 The player is on "daisy chain " mode

If the line is missing , the factory setting value by default is used it has to say 0, no monitoring.
See chapter 6 for informations on RS232 protocol.

5.6 - Choose of the playback folder when powering - #BOOT:xxx

Sometimes, it can be necessary to define the folder that will be used when powering. By default, the
directory 000 is used as a starting folder.

Command line:

#BOOT:xxx xxx a number between 000 et 999

Example:
#BOOT:015 the player will read the content of the 015 folder when powering..

If the line is missing, the " factory setting" value by default will be used , 000 for the folder 000.
If the folder does not exist , the player turns into standby mode and waits for an instruction

5.7 - Assign particular functions to the inputs - # INPUTxxx:function

By default, input contacts trigger folders in order to read their content. For a better versatility of the
player, it is possible to assign input contacts to others functions.

PLAY : Reading known file
STOP : Stop the current reading
NEXT_TRACK :. Reading of the next file of the folder currently read.
PREV_TRACK : Reading of the previous of the folder currently read.
VOLUME_PLUS : Increase the volume from one step
VOLUME_MINUS : Decrease the volume from one step
FOLDERxxx : Jump to the folder xxx - xxx can be a value between 000 and 999
RSxxx : Send the line n° xxx of the file " serial.txt " on the output RS232 ( with xxx from 000 to 999 ).

Command line :

#INPUTxx:function xx on input from 01 to 15 - function among the list below

Example of a command keypad using the 4 inputs.
#INPUT01:PREV_TRACK previous file playback
#INPUT02:STOP stop the playback
#INPUT04:PLA Y launch playback
#INPUT08: NEXT_TRACK next file playback

The 4 inputs are amongst themselves combinable in order to offer 15 different functions upon the
following table below.

#INPUT01 -> input 1
#INPUT02 -> input 2
#INPUT03 -> input 1+2
#INPUT04 -> input 3

5.8 - Assign particular functions to buttons - #BUTTONx:function

The two front buttons are dedicated by default to the volume setting. With the file config.txt, it is possible
to assign them other functions.

PLAY : Reading of the last known file
STOP : stop of the current reading
NEXT_TRACK : Reading of the next file of the folder currently read.
PREV_TRACK : Reading of the previous file of the folder currently read.
VOLUME_PLUS : Increase the volume from one step

6 - RS232 serial link protocol

The MicroPlayer can communicate with other devices by receiving instructions onto the Rx input or
transferring data through its Tx output. The player complies with the RS232 norm (see annex for
features).
V alue by default: 19200 Bauds ( modifiable through config.txt file) - 8 bits - no p arity - 1 bit start - 1 bit stop

6.1 - Reception Protocol

With the input protocol, the player can receive instructions to launch a folder playback or sets the volume
control. On the other hand , in a framework of the using of several players on the same link, the player
answers its own number ( defined in the file congig.txt, see chapter related ) or to a general command

The reception protocol is made of a 3 bytes frame.

Byte 1 (statut) + Byte 2 (command) + Byte 3 (data)

Reminder:

- a byte is composed of 8 bits: b7 b6 b5 b3 b2 b1 b0

- a binary representation is noted: 10000000b or in hexadecimal : 80h

Byte 1 : Status - 1xxxxxxxb

The byte status is a synchonization information of frame. Its Byte 8 ( b7) is always at 1. All others bytes
( commands or datas ) have their byte 8 to 0.

b7 = 1: refer to a status byte
b6 - b0: identification of the player to be addressed from 001 to 127 (000001b - 1111111b)

- The address of the player is by default (ID) 001. You can modify it in the conffiguration file.

- Several players may have the same identification number to create groups.

- Identification 000 is the "overall" code, all players are concerned by the command (unique command for
all the players).
Example:

80h = "overall" code for all the players
81h = player n°001
9Eh = player n° 030
FFh = player n°127

Byte 2 (Command) 0xxxxxxxb + Octet 3 (Data) 0xxxxxxxb

The Byte 2 is a command and the byte3 is a data that completes the command byte. A command byte
is always followed by a byte of data. A full frame is therefore made of 3 bytes.

b7 = 0 : refer to a byte of command or data
b6, b5, b4 : bank selection for the directory jump command
b3, b2, b1, b0 : command code sent to the player

● 00h - 00000000b: not used

●●

●●

● 01h à 71h - 0xxx0001b: command of jump towards a folder

The folder is designated by the bank number and the next data byte.
xxx is the bank number. To launch 1000 folders ( from 000 to 999 ) , it is necessary to divide this number

in several directory ranges (bank) of 128 values.
0xxx0001b: xxx= bank number depending of the folder number

01h - 00000001b: Bank 0 -> from 000 to 127
11h -00010001b: Bank 1 -> from 128 to 255
21h - 00010001b: Bank 2 -> from 256 to 383
31h - 00110001b: Bank 3 -> from 384 to 511
41h - 01000001b: Bank 4 -> from 512 to 639
51h - 01010001b: Bank 5 -> from 640 to 767
61h - 01100001b: BanK 6 -> from 768 to 895
71h - 01110001b: Bank 7-> from 896 to 999
(The binaries values beyond 999 are ignored)

Method of calculation:

1) bank = value in the above table depending on the folder number

2) value = folder number - (bank x 128)
Example of a frame triggering folder 278 in the player number 1:

Folder number = 278

1) 278 is in bank 2 (from 256 to 383)

2) Value = 278 - (2 x 128) = 22
The frame is:81 21 16

Byte 1: 81h - 10000001b: status byte, player number 001
Byte 2 :21h - 00100001b: bank 2, command of jump towards a folder
Byte 3 :16h - 00010110b : value 22 (reference of folder 278 in bank 2)

●●

●●

● 02h - 00000010b: Transport bar command

The transport function is defined by the data byte as follows:
value of the datas of the byte 3 (datas)

01h - 00000001b : Playback
02h - 00000010b: Stop
03h - 00000011b: Next file in the current directory
04h - 00000100b: Previous file in the current directory

Note: the other values are ignored.

● 03h - 00000011b: volume control command

The value of the volume is defined by the datas byte that follows:
00h - 00000000b : mute - volume at 0

20h - 00100000b : half volume - value 32
40h - 01000000b : maximum volume - value 64

Note : the others values are ignored

Byte3 : 0Eh - 00001110b : volume setting at 14

6.2 - Transmission Protocol - Monitoring

The MicroPlayer MKII can convey several kind of datas onto RS232 port.

- Personalised datas sent by tags [RSxxx] (see chapter "naming of files and folders).

- Command datas of the player sent in " Daisy Chain" mode

- Status datas of the player sent in mode "monitoring" and "advanced monitoring"
To define the kind of sent datas through RS232, 4 monitoring modes exist.
Mode 2 and 3 are defined in the configuration menu (see chapter configuration menu)

The "Daisy Chain " mode and the monitoring mode are added up with the sending information mode
through tags.

Mode 0: no monitoring mode

Only the datas sent through tags [RSxxx] are sent to TX output.

Mode 1: "Daisy Chain"

In this mode, any information received on the Rx line is resent out as received onto the line Tx.
This mode allows to chain up several players the ones after to the others. By connecting Tx output of the
first player to the Rx input of the second player and so on , the information received by the first player
on its Rx socket is resent to the others players in chain. Caution ! if numerous players are connected in
this way, a slight delay can exist on the end of the chain.

Mode 2: "Monotoring" mode

In this mode, the player send informations onto the Tx output depending on the actions executed. This
mode do not allow to chain up the players. The player allows to a PLC, a computer, a security system, to
know the status of the player and to make operating tests. In this mode, the player send datas of its
status upon each change.
The transmission protocol is made from a 3 bytes frame, similar to the reception protocol.

Byte 1: Status

7 - From the MicroPlayer to the MicroPlayer MKII

The MicroPlayer MKII has evolved and the file/folder naming mode has changed. To ease this proceed
from the old model to the new one, please find hereafter some elements that might help in this proceed.

Naming of the folders:

Loop playback of a folder in a random mode:

001001R -> 001[J001]
or
001001R -> 001[J001][RND]

Loop playback of a folder in a sequential mode:

001001S -> 001[J001][SEQ]

Random playback of a folder then the player stops

001###R -> 001

Naming of the files:

Jump in another folder after the reading of the file, the file can be interrupted:

001001T.mp3 -> [J001] my file.mp3

Jump in another file after the reading of the file, the file can NOT be interrupted:

001001N.mp3 -> [J001][NT ] my file.mp3

Files playback in a sequential mode, files can be interrupted:

001###N.mp3 -> 001.mp3
002###N.mp3 -> 002.mp3
003###N.mp3 -> 003.mp3
004###N.mp3 -> 004.mp3

Without any option, no change, files can carry any name:
