1. GENERAL DESCRIPTION
3
The new DMX-512 protocol-controlled PX249 audio player replaces the previous version – MP3
PX154.
The device can be controlled directly or with the use of any driver operating in the
DMX-512 standard. The player can mate with DMX devices in four- or seven-channel modes.
The SD/MMC card can be uploaded with up to 85 tracks in the WAV format of any length, the only
limitation is the capacity of the memory card.
Functions implemented by PX249 using DMX control allow for playback, selection of
a particular song, looping one and multiple tracks, smooth volume control, bass, treble and
balance control. Additionally, there is a possibility to connect an external START button.
Moreover, the menu of the device allows for defining the behaviour of the player if no DMX signal
is present.
The unit is produced in a housing adapted for mounting on 35-millimeter DIN buses which
facilitates installation to a great extent.
The PX249 Audio DMX Player is a device powered with 12 - 24V safe voltage. However, during
its installation and use the following rules must be strictly observed:
1. The device may only be connected to 12-24V DC current (stabilized voltage) with current-
carrying capacity compatible with technical data.
2. All the conductors should be protected against mechanical and thermal damage.
3. In the event of any conductor damaging, it should be replaced with the one of the same
parameters.
4. Connection of DMX signal should be made with shielded conductor.
5. All repairs and connections of outputs or DMX signal can only be made with switched off power
supply.
6. The PX249 should be strictly protected against contact with water and other liquids.
7. All sudden shocks - particularly dropping - should be avoided.
8. The device cannot be turned on in places with humidity exceeding 90%.
9. The device cannot be used in places with temperature lower than +2°C or higher than +40°C.
10. For cleaning use only a damp cloth.

5. PLAYER STATE AFTER TURNING ON THE DEVICE
When PX249 is turned on, the start menu appears on the screen. The menu design varies
depending on whether the device is receiving the DXM signal or not. Direct keyboard support
(played track control) is possible when the DMX signal is not being received.
Selecting the [Menu] screen button and confirming the selection by pressing the „enter” button
allows for entering the menu in which the DMX address, number of DMX control bytes, behaviour
of the player if no DMX signal is present and the parameters of a played track can be set.
If no DMX signal is received, you can change the playback settings directly on the initial menu. To
do so, you need to select the icon:
play
pause
stop
rewind
forward
and then confirm your selection by pressing "enter"
Similarly, you can change the volume level, playback mode and track number. To do this, use the
following keys: and

6. AUDIO FORMATS, MEMORY CARDS AND FILES NAMING
The Audio DMX Player supports audio files in the .wav format with the following parameters only:
ź *.wav files with bits per sample value of 16-bit on two-channels
ź acceptable sampling frequencies:
- 48 kHz
- 44,1 kHz
- 32 kHz
- 22,05 kHz
- 16 kHz
- 11,025 kHz
- 8 kHz
NOTE: The player supports only SD or SDHC cards formatted in the FAT32 file system.
Moreover, the memory card cannot contain more than 85 files. A higher number of tracks or
additional directories can result in the module's malfunctions when changing tracks.
Tracks on the SD card should be named according to the following principle:
xxx_ABCD....O.wav
where:
xxx - numbers from 001 up to 085
ABCD....O - up to 15 alphanumeric characters
*.wav - WAV files extension
Example:
001_Music.wav
002_Mozart.wav
003_Beethoven.wav
085_Chopin.wav
NOTE: If the correct track naming or the maximum number of tracks are not followed, playback or
track changing problems may occur.

ź run - the player automatically starts the track set in the [Default values] visible in the same
menu
ź last - the player resumes its operation
ź ext1 - starts a track using an external button in accordance with the parameters defined in
[Default values], each successive press of the external button will replay the defined track
ź ext2 - starts a track using an external button in accordance with the parameters defined in
[Default values], each successive press of the external button during the course of the track
will have no effect, the track will be played to the end
11. ADDITIONAL OPTIONS
In this submenu, you can change the interpretation of the 0
DMX value by the PX249.
By the default the 0 value for each channel is changing the
behavior of the device (e.g. For channel 1 stops playing), but
after checking the box in this menu the zero is interpreted as
neutral.
[DMX filter] - filtration of short-term changes in the DMX
signal. The player will react to the value if it remains
unchanged for at least 5 DMX frames.

13. FIRMWARE UPDATE
The PX249 firmware update procedure is as follows:
1. prepare an empty SD card (FAT32 file system)
2.upload only the update file to the card (extension: .upg)
3. disconnect the Audio DMX Player from the mains
4. remove the existing SD card and insert a new one that is updated
5. reconnect the updated device to the mains.
The update procedure is automatic. After the end of the process, the start menu will appear.
NOTE: After the update has been completed, remove the card with the update as otherwise it will
update your device whenever it is powered up.
[Equalizer] - turning the equalizer on allows for changing the sound timbre. Turning it off
increases the volume level.
[DMX volume lock] - when the DMX is used for control, the volume level is locked at a value set
using the keyboard. After restarting the device, it takes the value from the [DMX Settings] menu.
