1. GENERAL DESCRIPTION
2. SAFETY CONDITIONS
PX254 LED Driver 3 x 6A OC is a device powered with safe voltage 12-24 V; however, during its
installation and use the following rules must be strictly observed:
1. The device may only be connected to 12 - 24 V DC 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 damaging any conductor, it should be replaced with a conductor of the same
technical data.
4. Connection of power supply can only be made with a conductor of minimum cross-section area
2
of 2,5mm and DMX signal with shielded conductor.
5. All repairs and connections of outputs or DMX signal can only be made with cut off power
supply.
6. PX254 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. Clean with damp duster only.
PX254 driver is designed to control the LEDs. Built-in DMX receiver allows to control 3 DMX
channels (R, G, B) directly with the DMX protocol. Wide range of power supply voltage and high
current carrying capacity outputs (6A) permit a control of large quantities of LEDs. What is more
the PX254 has built-in fuses that can be replaced by the user by himself.
PX254 can be either controlled by DMX, and act independently. In this case, the user is offered a
fully programmable scene and 18 pre-programmed sequences, which can also freely change the
playback speed and fluidity changes in steps. By using 16-bit resolution control of each channel
is completely smooth. In addition, the PX254 driver gained control mode called effect mode to
control the programs built into the driver and the simultaneous change the settings of parameters
such as speed, brightness and fade using DMX-512 signal sent from the external controller.
The driver has a built-in tuning frequency signal system ("flicker free" technology), which makes it
particularly useful in applications for the television industry. The RGB LEDs often differ quite
substantially in parameters, this can cause problems in obtaining a white color (at full power
especially). Therefore PX254 comes with a very useful function called "white balance". Thanks to
it you can choose color correction for each set of LEDs controlled by the device to achieve at full
power the color white. What's more, this feature also allows you to adjust the color temperature of
white color.
The PX254 is produced in common anode version - it allows LEDs connection on common
anode.

5. DMX ADDRESS SETTING
The menu of the PX282 driver allows for setting the DMX address within a range between 1 and
506-511 depending on work mode of device. For example in RGB mode it occupies three
consecutive DMX addresses. If start address is set to 510, the last channel is occupied by
address 512.
To set the DMX address:
1. Set the Adr function.
2. Use the "next" or "previous" buttons to set the selected DMX address.

7. MASTER / SLAVE FUNCTION
The PX254 module has a built-in DMX-512 receiver and can be controlled from any desktop or
controller running in this standard. Moreover, it is equipped with a programmable function of
response to no DMX signal (noS). With 18 built-in default programs, it is possible to obtain
interesting effects without an external controller. However, in larger installations, several PX254
drivers implementing the same program cannot provide a full reproduction synchronisation.
Therefore, PX254 has a MASTER feature. When it is activated, the module changes from a DMX
receiver into a transmitter of this signal and sends self-realized programs to the other modules
(which are set as SLAVE). With this solution, it is possible to make a precise synchronization even
in very large installations.
To turn on the MASTER feature you must enter the
"C-d " section. Press the „enter” key, the "Con" message
will show up on a display.
To choose the number of emitted DMX
channels in the "Con" section press the
next key. The "Chn" will show up on the
display.

6. DISPLAY FLIP FUNCTION
As the driver should be installed in a small distance from the controlled LEDs, the lack of space
may force the necessity of mounting the device upside-down.
In such case the displayed messages become illegible, that does not have the influence on
device operation, but makes the programming much more difficult.
That is why the PX254 driver has a display flip feature available. It turns the screen 180°. The
keys order is reversed as well.
To activate this both middle buttons (PREVIOUS and NEXT) of the driver have to be pressed in
the same time for about 3s. To deactivate function the procedure is the same.
The figure below shows how flip function works.

9. COLOUR MODE
Sometimes, there can be problems with getting white colour on the RGB series LEDs. This may
be a result of using diodes with different technical parameters. For this reason, the PX254 module
is equipped with a white balance function. This option allows for choosing a correct colour
temperature for full activation of all 3 outputs (white colour).

To set the white balance:
1. Enter the bAL function.
2. Select an appropriate value for each of the selected channels.
bLr - for red
bLG - for green
bLb - for blue
3. Enter the bCn option to accept or reject the pre-selected
values.
4. on means that white balance is turned on.
5. oFF means that white balance is turned off.
The PX254 driver can operate in the 4-channel, 3-channel or 2-channel
HSL mode. The HSL mode (Hue, Saturation, Lightness) operates on
three channels, responsible for hue, saturation and lightness,
respectively. Working in the 3bd mode (4-channel, 4-byte) allows for
setting each colour individually: R (red), G (green), B (blue) and, on the
fourth channel, the Dimmer function is implemented - dimming all
outputs. In the 3-channel mode (3 -byte), each colour (R, G, B) can be set
separately. Whereas working in the 2-channel mode (2-byte) consists in
selecting lightness and one of the 256 colours defined by the
manufacturer. EFF (effect) mode is described on next page.

NEXT
ENTER
CAUTION:
PX254 basically sends three channels (R, G, B), but because the DMX standard defines the
minimal emitted channels number as 24, these three channels are duplicated eight times. If there
is such a necessity, you can increase them up to 512 channels (this setting is not recommended
because of the decrease of a transmission speed).
To select the colour mode, enter the Cbn function in the ALL menu, and then select the
desired colour mode: 2b for the 2-byte mode, 3b (3-byte mode), 3bd (RGBDimmer
mode), HSL or EFF for the Effect Mode. After setting one of the mode in the individual
settings menu (see section 10), the number of editable channels will be limited in
accordance with the selected mode (e.g. up to 2 channels for 2b-2byte).

11. NO DMX SIGNAL RESPONSE
This function is used both to protect the installation against the DMX signal loss and to obtain
control over LEDs without connecting an external controller. Once it is activated, if there is no
DMX signal the module will realize a desired function independently. Reconnecting the DMX
signal will automatically break the realized function and the module will once again follow the
commands transmitted via the DMX line.
To program individual settings:
1. Enter the individual settings function marked as Ind.
2. Go to the first output settings marked as Ad1.
3. Using the „next” or „previous” buttons set an appropriate
value. You can choose from 1 up to 512.
4. Set the address for the remaining outputs (defaults values
are subsequent values from 1 for the first output up to 7 for
the seventh output).

10. INDIVIDUAL SETTINGS
The PX254 module has an option that allows for changing individual settings. It enables
assigning any DMX address to every output channel. The simplest example of implementation of
this function is to control the lightness of one-colour LEDs connected to all outputs. In this
example, the same address must be assigned to all channels so that all outputs are controlled by
one slider on the control panel.
