8. WHITE BALANCE
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).

3. Enter the

option to accept or reject the pre-selected
values.

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.

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).
