Cygnus™ Operation
RGBMaster and RBGWhite Mode
The Cygnus™ can be operated in either RGBMaster or RGBWhite mode.
In RGBWhite mode, the DMX channels (or channel pairs in 16-bit mode) directly
control light output of the four LED colors independently. Achieving a “white” is
done through the user selecting values for the four color channels. There is no
master fader channel in this mode.
In RGBMaster mode, all color is selected only through the RGB channels. A
fourth channel acts as a master fader for the color mix. If the RGB channels are
all at the same level then the fixture will produce a white light as a combination of
white and other LEDs to achieve a desired white balance. In RGBMaster mode
there is an additional channel to select the white color temperature. If this channel
is set to 0-7% the default white color temperature of 3500 degrees K will be used.
DMX values of 8-100% allow a continuous color temperature selection from
2000 to 7500 degrees K. Color temperature values for specific DMX values can
be found in Appendix B.
Strobe Mode
The Cygnus™ can strobe at rates between 0.25 and 30hz. The Strobe Frequency
channel is used to enable strobing and to select the strobe frequency. If this
channel is set to 0-7%, strobe mode will be off and the unit will operate normally.
If this channel is set to 8-100%, then strobe mode will be on and the strobe speed
will vary from low to high. The unit will strobe with a color and intensity selected
from either the RGBW or RGBM channels.
The Strobe Duration channel allows the user to control the strobe pulse duration
from near 0% to near 100% of the strobe period. A strobe duration of 20-50% will
produce a brighter strobe than if this channel is left at zero.
The Strobe Effects channel allows the selection of pre-defined color jump
sequences in strobe mode. Use Table 1 to set this channel to a specific value to
select a color sequence. In order to enter strobe effects mode, a minimum
DMX value of 8% is required on the Strobe Frequency AND the Strobe
Effects channels.
If strobe effects are selected, then the RGB channels have no effect. If the unit is
in RGBMaster mode and strobe effects are selected, then the Master channel will
still control total light output. If the unit is in RGBWhite mode and strobe effects
are selected, then the White channel will be used as a master fader channel.
