parks & tourist attractions…
2 - Functionnalities
Interactivity: VP250HDi is an interactive player that reacts according to events.
- Playback pattern is dened by the name of the les or the folders
- Electrical contacts: 1 input to trigger les through sensors, push-buttons,relays …
- 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: VP250HDi starts automatically on powering on. This function is congurable and can be disabled.
Playback: The audio les stored on a USB ash drive can be organized in a particular way to dene
playback pattern. The playback pattern is dened by the names of the les and the folders, allowing a
wide exibility of use.
Video output : 3 types of output are proposed :
- HDMI output (digital)
- VGA analog - 15 pins Sub D
- Analog video composite output (4 points mini-jack - video + audio)
Ethernet : Use this link to update the les on the medias (USB, SD card) from your netmwork or through
internet
Power supply: A 12v external power supply is required.
The player is protected against polarity reversals.
Caution! The player doesn’t accept a tolerance of the power supply. Apart from the 12V, the player can
be damaged.
The input supply is transferred to the RS232 connector and the output terminal (RTB) to supply the
connected accessories. (limited current)
The power of the PSU determines the output power of the amplier. When a line level output is used , a
1A (12w) power supply is adequate to run on the player. When the amplied output is used for larger
powers, a supply of at least 3,50A (45w) is compulsory. If you use a PSU from an inferior power, you can
have a very poor sound and also an overheating PSU till broken down.
Serial link RS232: VP250HDi can be controlled by a PLC, a computer, a remote control using a serial link.
VP200HD receives data on its Rx input and sends datas on its Tx output. A specic protocol is described
in this manual.

4 - Operating mode
See in annex at the end of this manual, the compatible les.
The name of the les and folders dene the playback mode. The les and folders must be stored and
copied according to a specic organisation described below.
4.1 Organisation des dossiers :
Only ONE folder level is allowed at the root. The folder naming is 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
127 [SEQ][J001] my folder
Conguration folder: SYSTEM
SYSTEM folder is used for optional conguration les. See next chapter.
● The rst three digits represent the folder number 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 - Triggerable by the contact input 1
034 : Folder N° 34
The folder number is used identies the folder to use during a jump or an input triggering. You can use
any number between 000 & 999.
IMPORTANT : The trigger contact input select folder to be played
See at the end of chapter 4 the details of the use.
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 les of this folder.
If this folder is missing, the player turns in wait mode (black screen) or play the «waitscreen.jpg» le.
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] - Species random or sequential playback mode for the current folder.
[Vxx] - Controls the volume level of the folder
[NT] - Dene interruption modes
[RLSx] or [RLEx] - Active or deactive the outputs contacts (when play folder or at the end)
[RSSxxx] or [RSExxx] - Sending of RS232 codes at the begining or at the end of the folder
Note: If no optional parameter has been indicated, the player reads in sequential the folder in full and then
stops. The folder can be interupted
●[Jxxx] – Assign the folder No. to be read after the reading the current folder.

- 10 -
By adding this parameter within the name of the folder, you dene 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
127[J000] : Jump to folder 000 after reading folder 127
To play loop les on powering on, you will use the folder 000 and the tag [J000]
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 les 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 di󰀨erent 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)
●[SEQ] or [RND] - Point out the sequential playback mode for the current folder. By default or without
parameter, the folder is read in a sequential mode.
[SEQ] or without any parameter: reading in a alpha-numerical order
[RND]: 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 sequential mode then jump to folder 001.
By choosing [SEQ] you select the sequential mode, which means a reading in a dened order. The sorting
is made through a alphanumerical order it has to say in the order of the letter/numbers of the names of
the les.
By default, if optional parameter is not present, the reading is made in a sequential mode.
●[Vxx] - Volume setting

® Waves System V 1.0 - 2014
I.D. AL - VideoPlayer VP250HD - Video/Audio player - User manual
- 11 -
The name of the folder have an e󰀨ect on the output volume. This function is used to broadcast messages
loud more or less than others les.
Exemple :
001 [V05] : Volume is set at 5 from 32 step (00 to 31)
001 [V31] : Volume is set at 31, maximum value
001 [V00] : Volume is set at 00, minimum value (Mute)
- If the variation of values exceeds the minimum or maximum values of the player, the levels are settled
to their maximum or minimum.
- If the volume level is set to its maximum or minimum, the instruction is ignored.
●[NT] - This option denes the interruption mode of the folder currently read.
If this options is registered within the name of the folder, the read le cannot be interrupted and instructions
received are ignored.
Without this option, the reading of the currently read directory can be interrupted any time by an
external action. (input, 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 le is not stopped.
Caution! The action is not memorised and the triggering information is lost.
●[RLSx] and [RLEx] - Active or deactive the outputs contacts (when play folder or at the end)
The output contact is switched on/o󰀨 by the name of the folder when player start to play the folder [RLS]
or at the end of the folder [RLE].
[RLSx] : x is the state of the output wheb start to play the folder. 0 = o󰀨 / 1 = on
[RLEx] : x is the state of the output at the end of the folder. 0 = o󰀨 / 1 = on
With thos 2 options, you can swith on a lamp during the audio le and swith o󰀨 at the end.
x is the state of the output :
If x = 0, the output is switched o󰀨, no contact.
If x = 1, the output is switched on, a contact is made from output to the ground (GND)
Example :
001[RLS1] The output is switched on when start to play the folder 001
002[RLE0] The output is switched o󰀨 at the end of the folder 002
003[RLS1][RLE0] The output is switched on when start to play the folder 003 and switched
o󰀨 at the end of the folder
●[RSSxxx] ou [RSExxx] – These tags allows to send bytes 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 le that will be espe-
cially created for.
Value by default : 19200 Bauds - 8 bits – no parity – 1 bit start – 1 bit stop
The le denition of the bytes to send must be named : serial.txt
This le will be copied in the SYSTEM folder of the media (memory card/ash drive)
[RSSxxx]: xxx appoint the number of the line of the le serial.txt that must be sent (value from 001 up to
999) when player starts to play the folder
[RSExxx] : xxx appoint the number of the line of the le serial.txt that must be sent (value from 001 up
to 999) at the end of the folder
The «serial.txt» le is a text le (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 le «serial.txt» of RS232 codes is a text le 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 le should present the following parameter:
#xxx : the xxx number of the line containing the bytes to send related to the xxx of the tag.
[RSS002]-> line #002 – the tag [RSS002] will send the sequence of bytes of the line #002 of the serial.txt le.
The separator between each byte is a space.
Example of a line contained in the serial.txt le.
#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 in the le by using
two times the type «/» (slash) = //
// example le
#001: 05 A1 FF E4 // comment in the line
#005: 45 85 63 21 78 A5 B2

5 - RS232 serial link protocol
The VP200HD 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).
Value by default: 19200 Bauds - 8 bits - no parity - 1 bit start - 1 bit stop
5.1 - 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 using several players on the same link, the player answers
to its own number ( dened in the le 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: identication 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 conguration le.
- Several players may have the same identication number to create groups.
- Identication 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, b3, b2, b1, b0 : command code sent to the player

6 - Ethernet
Via the Ethernet link, the VP250HD communicates either to update content via FTP (SD card or USB stick).
You can use the player in a local network. An adequately congured Modem/Router will allow update the
player via the Internet.
Caution! Network administration requires good computer skills.
In a local network installation, the player requires an IP address. This address is set in the Option menu
(see option menu chapter). The player is then recognized on the network as a FTP server with a FTP
software such as «Filezilla».
In an installation where only the player is present or in a local network with external access, you must use
a Modem/Router to create a gateway between the player and the Internet.
Since the Modem/Router is congured with an IP gateway, you must declare this gateway to the VP250HD
so it can communicate outside (to be congured in the Option menu).
Note: The VP250HD o󰀨ers a DHCP mode to get an IP address automatically.
Default user : idalftp
Default password : idalftp
How to change the default user and password :
To change the user name and password of the FTP access, you need to use a text le which is copied on
the main media including the audio/video les. You can create this le with the «Notepad» software or all
other simple text editor.
