DMX ADDRESS setting 

 
The DMX address, also known as the start channel, is the 
first  channel  used  to  receive  instructions  from  the 
controller. For independent control, each rotator must be 
assigned its own control channels.  
The  DMX  address  is  configured  using  the  three  DMX 
ADDRESS selectors on the rotator. The selected DMX address states from which channels, on the 
lighting  desk,  the  rotator  is  controlled.  The  DMX  address  can  be  selected  from  1  –  505.  The 
Rotator 281 uses six DMX channels. 
 

DMX channel 1 – Position rough (16 bit DMX channel): 

This channel controls the position of the rotator, with the speed (DMX channel 3).   This  rough 
position works together with the fine position (DMX channel 2). The rough position and the fine 
position are multiplied in to a 16 bit channel. The rough position is the 

MSB

 

DMX channel 2 – Position fine (16 bit DMX channel): 

This channel controls the position of the rotator, with the speed set on DMX channel 3. This fine 
position  works  together  with  the  rough  position  (DMX  channel  1).  The  fine  position  and  the 
rough position are multiplied in to a 16 bit channel. The fine position is the 

LSB

 

DMX channel 3 – Speed: 

This channel controls the speed of the rotator. 
This channel defines the maximum speed. The  rotator  runs with the set max speed, but  slows 
down as closing in on the wanted position. This channel also works as a main brake; the motor 
does not run unless the channel is set above 0%. The speed-channel can also be used to make 
soft and slow movements or fast and sudden movements. 
 

DMX channel 4 – Manual CW / Set CW end position: 

This channel makes the rotator, rotate clockwise (CW). The channel value determines the speed.  
If DMX channel 6 is set between 51-54%, the end position for 

position mode

 is saved.  

 

DMX channel 5 – Manual CCW / Set CCW end position: 

This channel makes the rotator, rotate counter clockwise (CCW). The channel value determines 
the speed.  
If DMX channel 6 is set between 51-54%, the end position for 

position mode

 is saved. 

 
DMX channel 6 – Mode Control: 

 

Channel value

0-79%   

Position mode 

51-54%   

Position mode and enable ‘end position’ save

Attention!  The  positioning  run  in  positioning  mode  works  only,  when  the  rotator  has  been 

reset.
