Shutter blades are superficially comparable to an iris because both systems sharply define the light beam. However, unlike the iris, shutter blades are mechanically much more complex and require up to eight individually controllable actuators to remotely control the numerous individual blades typically installed in the shutter blade module via DMX. With the help of a shutter blade module, the light beam can be shaped into a precise illumination of objects and scenes, for example, in the form of a triangle or rectangle, such as in theatre productions. For graphical control, the GUI provides a corresponding Control Panel.

Case	Code example
Blades are retracted via one DMX channel, and the second channel determines the angle	<blades> <bladetop dmxchannel="0" /> <bladetopangle dmxchannel="1" pointofrotation="center"> <range range="60" mindmx="0" maxdmx="255" /> </bladetopangle> <bladeright dmxchannel="2"/> <bladerightangle dmxchannel="3" pointofrotation="center" > <range range="60" mindmx="0" maxdmx="255" /> </bladerightangle> <bladebottom dmxchannel="4" /> <bladebottomangle dmxchannel="5" pointofrotation="center"> <range range="60" mindmx="255" maxdmx="0" /> </bladebottomangle> <bladeleft dmxchannel="6"/> <bladeleftangle dmxchannel="7" pointofrotation="center" > <range range="60" mindmx="255" maxdmx="0" /> </bladeleftangle> </blades> Shutter blade module from DMX channel 1: Depth of retraction of the upper blade via DMX channel 1 and inclination in a range of +/-30° via DMX channel 2. Depth of retraction of the right blade via DMX channel 3 and inclination in a range of +/-30° via DMX channel 4. Depth of retraction of the lower blade via DMX channel 5 and inclination in a range of +/-30° via DMX channel 6. Depth of retraction of the left blade via DMX channel 7 and inclination in a range of +/-30° via DMX channel 8.
Blades are retracted via two DMX channels, whereby the inclination is realized by a value difference between the corresponding DMX channels	<blades> <bladetop dmxchannel="0" /> <bladetop dmxchannel="1" /> <bladeright dmxchannel="2" /> <bladeright dmxchannel="3" /> <bladebottom dmxchannel="4" /> <bladebottom dmxchannel="5" /> <bladeleft dmxchannel="6" /> <bladeleft dmxchannel="8" /> </blades> Shutter blade module from DMX channel 1: Depth of retraction of the upper blade via DMX channel 1 and 2. Depth of retraction of the right blade via DMX channel 3 und 4. Depth of retraction of the lower blade via DMX channel 5 und 6. Depth of retraction of the left blade via DMX channel 7 und 8.
Indexing of the entire shutter blade module	<blades> <bladeindex dmxchannel="0"> <range range="90" mindmx="0" maxdmx="255" /> </bladeindex> </blades> Rotation (indexing) of the entire shutter blade module in a range of +/-45° via DMX channel 1.
