B.
Function of the DMX channel No. 7.
The DMX channel 7 is functioning as so called virtual colour changer.
DMX 7 value
0
The function of the channel 7 is switched off.
1 - 255
In the range of these DMX values 30 fixed memories are available, in which
you can store any colour or any colour shade.
This has been added for reasons, when the user wants to have the exact shade of color placed
directly in the luminaire and does not want to be dependent on the type and capabilities of the
lighting control console.
The use of this function is practical especially when setting the colour temperature by taking photos
or motion-picture operations or when the control is made with a small control console, which does
not have controls for colour mixing.
The term "virtual color changer" perhaps best describes the function of the DMX channel No. 7. In
case of classical color changer we would scroll a mechanical band of 30 gel strings. In our case we will
change over between 30 memories. The advantages again a classic scroller are clear. The user may
anytime change any of the colors or change over the color sequence. Also there is no time delay by
the scrolling of the gel strings!
ATTENTION! When the DMX channel No. 7 is active and its value is higher than 0 then the RGBW
color mixing is disabled. The color in the memory has the priority over the RGBW color mixing! If
you will not use the channel 7 then it is more practical to disable this channel.
