5. CURRENT PLAYER STATUS
6. DIRECT CONTROL
Direct control (with the control keys) is possible when the DMX signal is absent (DMX LED off)
only. You can operate with the four following keys:
PLAY/STOP - plays / stops / pauses / restarts playing
VOLUME "+" and "-" - adjust the volume level
NEXT - next track selection
PREV - previous track selection
7. DMX CONTROL
With the DMX protocol the player control can be held through four or seven channels. In the 7-
channel control mode the following features are available: play / stop / restart, track number
selection, reproduction mode (one track or all tracks once and one or all tracks in a loop), volume
adjustment and a three tone equalizers (high, medium and low). When the 4-channel control
mode is set the equalizer is unavailable - you can adjust the tones manually in the player's menu
(dEF section).
When the PX154 player is switched on, the software version number is displayed. After
approximately 2 seconds the currently played track number appears. The direct control with the
functional keys is possible, when the DMX signal is absent. The player starts with the 0 volume
level and selects (does not play) track no. 000 then. The equalizer is set at the default level, as
well as the single playing of one track. By pressing the PLAY/STOP key you can start playing the
selected track. The special case is the "run" feature activated (refer to p. 8.3 of the manual).
When both volume keys are pressed simultaneously you can enter the player's menu, where the
following parameters can be set: the DMX address, number of DMX control bytes, player reaction
to DMX signal absence or interruption and the played track parameters.
ATTENTION: When the SD/MMC memory card is empty, the player can be used as the Master
Mass Storage device, that is a removable disc, only! The control with the functional
keys will not be possible.
Moreover, the number of files put on the SD/MMC card cannot exceed 26. If there is more files or
any additional folders are put on the memory card, it can cause improper player operation during
tracks changing. All the mp3 files must be saved in format 000.mp3, 001.mp3, ... , 025.mp3.

Channel 3: reproduction mode - single (the selected track is played once), single looped
(the selected track is played repeatedly), continuous single (starting from
the selected track, playing comes to the last track and stops when the last
track was played), continuous looped (starting from the selected track,
tracks are played in turn, after the last track was, the player starts to play the
first track, and so on)
DMX values:
0 - 63 - single reproduction
64 - 127 - looped single reproduction
128 - 191 - continuous single reproduction
192 - 255 - looped continuous reproduction
ATTENTION: each change of playing mode through the DMX protocol auto-
matically selects the track and realizes the start / stop command
Channel 4: 32-grades volume adjustment
Channels 5, 6, 7: tone equalizer - in sequence: low tones, medium and high (32 grades
each)

volume level
To enter the player main menu press both volume adjustment (VOLUME + and -) keys
simultaneously. Moving around the menu and options selection is performed with the following
keys:
VOLUME "+" - ENTER (enters the successive submenu and confirms your selection)
VOLUME "-" - ESCAPE (returns to the previous menu and discards changes made)
NEXT - scrolls the menu forwards and increases the parameters values
PREV - scrolls the menu backwards and decreases the parameters values
8. PLAYER MENU
The player menu allows to define the parameters of a played track, set the player reaction to DMX
signal interruption, choose the control mode (number of DMX control bytes) and to set the DMX
address. When the programming is performed, the tracks reproduction is not interrupted (the only
exception is the dEF menu parameters programming).

8.3. noS MENU
Defines the player reaction to DMX control signal absence or interruption. You may choose from
three following options:
oFF - playing is stopped and all the parameters are being reset, the player status is the
same as it is after turning the device on. Full control with the functional keys on the
front panel is possible.
run - the device automatically plays the track defined in the dEF menu with the
parameters set in the dEF menu as well
InP - you can launch the track with the external button, it is played with the parameters
set in the dEF menu, by pressing the external button once more, you will restart
the player with dEF parameters as well

8.1. Adr MENU
This is a first parameter to be set. In this menu you can select the player DMX address. The
address set corresponds to the first channel, the following channels will be ascribed to the
subsequent DMX addresses. The range you can choose from is from 1 to 505, regardless of the
control bytes number.
8.2. Cbn MENU
It defines the control mode through the DMX protocol. Allows to select one of two available
modes: 7-byte (7-channel) control (all playing parameters, volume and tone adjusting is
available) and 4-byte (4-channel) control, that ignore the tone equalizer. This parameter can be
adjusted manually in the dEF menu then.
VOLUME + NEXT
VOLUME + NEXT NEXT NEXT NEXT
8.4. dEF MENU
Allows to define the parameters of a played track. You have seven channels at disposal, for each
channel you can set the value in a range from 0 - 255, same as in a 7-channel DMX control. When
the parameters are being adjusted, you have the possibility to hear the changes made.
ATTENTION:
When the DMX signal is absent, the dEF menu settings after leaving the dEF
submenu, are held until any key is pressed - in this moment the playing mode,
if different, is changed into single.
When the DMX signal is present, leaving the dEF submenu causes the instant
launch of a command set on a DMX controller.
Ch1 - stop / pause / play / restart
Ch2 - track number
Ch3 - playing mode

9. COMMUNICATION WITH A PC COMPUTER
PX154 DMX-MP3 Player may be connected to the PC computer through the USB cable. When
connected, the USb inscription will be displayed and the MP3 LED will twinkle. The computer
identifies the player as a removable disc. The file transfer can be performed with the easiest
methods: "drag and drop" or "copy / paste". If the SD/MMC memory card is empty, the device can
be used as the Master Mass Storage device (removable disc) only. Moreover, if the PC is
equipped with the memory card slot, the files can be transferred directly to the SD/MMC card.
ATTENTION:
The number of files put on the SD/MMC card cannot exceed 26. If there is more files or any
additional folders are put on the memory card, it can cause improper player operation during
tracks changing. All the mp3 files must be saved in format 000.mp3, 001.mp3, ... , 025.mp3.
