User manual // DMX  

1  Setting of DMX address.  The DMX address is set on the 3 DMX wheels mounted inside the 

motor box. The red lamp flashes when addresses outside 1 to 512 are chosen.     

2  Connecting of DMX .  The DMX signal is applied with a standard 5-pole XLR-plug.  

The red lamp shows a constant light when a good signal is found and flashes if the DMX signal 

is bad or missing. 

3  Mounting of the disk.  The disk is mounted on the motor axle.  When the desired angle has 

been found, the disc can be tightened with the small black screw.  For this you may use the 

small screwdriver included with the projector shutter. 

4  Use of the projector shutter.  When 220 volts and the DMX have been connected, the 

projector shutter is ready for use. By changing the percentage of the chosen DMX address, the 

motor axle can be made to turn forward and backward following the DMX percentage. The 

motor axle can turn from 0 to 180 degrees, 0% equalling 0 degrees and 100% being 180 

degrees.
