“P” DMX Preset Mode
If you want to run the pre-programmed patterns and scenes by an external DMX-
controller you can use the DMX Preset Mode. Press the MODE button (5) until the
display shows “P”, indicating operation in “P” (DMX Preset) mode. Set the DMX starting
address by simply using the UP/DOWN buttons (6/7). The chosen DMX-address comes
effective approximately 3 seconds later and will show up on the display (2) in
alternation to the “P”.
The unit receives DMX values on a packet of four channels and mirrors the received
data on the DMX output (13). If a DMX signal is present the DMX LED (3) will turn on.
The four channels control the unit as follows:
If DMX-value of channel 3 is lower than 50 the unit works with static colours:
DMX Channel Value Range Function
CH1 000-255 Colour choice from presets (see “C” mode)
CH2 000-255 Dimmer
CH3 000-049 Static colour mode active
CH4 000-049 Strobe off
050-255 Strobe (050=slow / 255=max. speed 23 Hz)
Colour presets can be activated by means of CH1 whilst the chosen colour can be
dimmed by weighting the colour balance with CH2. If the value of CH4 is above 50 the
unit is set to strobe mode. The strobe speed for any fixed colour chosen on the first
channel can be adjusted from zero (value <50) to 23 flashes per second (value 255).
If DMX value of channel 3 is equal or higher than 50 the unit works in pattern mode:
CH1 Pattern CH1 Pattern
000-015 Soft fade red-green 136-150 Hard switch green-blue
016-030 Soft fade green-blue 151-165 Hard switch red-blue
