DMX-controlled operation
The Stage Cyclo may be operated with any USITT DMX (1990) lighting
control device. The fluorescent tubes can be dimmed from maximum output
right down to zero using four channels on a DMX controller. This allows a
wide range of color shades with almost infinitely variable intensity to be
obtained using additive color mixing. The color temperature of white light
can be fine-tuned by running the white tube at high power and adding blue
or red at low power. Replacement white tubes with various color
temperatures are available (see “
Accessories ” on page 31).
The four DMX channels are used to control the tubes as follows:
S e t t i n g a D M X c o n t r o l a d d r e s s
The DMX address, also known as the start channel, is the first of the four
DMX control channels used. It must be set on the fixture’s DIP switch before
the controller can send commands to the fixture. The Stage Cyclo responds
to commands sent to the DMX address and the next three channels. For
example, if the DMX address is set to 100, the Stage Cyclo uses channels
100, 101, 102 and 103.
Allow enough channels when setting the DMX address. If control channels
for two fixtures overlap, one of the fixtures will receive the wrong
commands.
If two or more Stage Cyclos
share the same DMX address,
they will receive the same
c o m m a n d s a n d r e s p o n d
identically. Individual control
will be impossible.
To access the fixture’s DIP
switch, slide the hatch open
by pulling on the pin in the
connections panel recess (see
Figure 11)
