10.8 Iris
About the Iris
When projecting images in light mode, a circular beam is used. As the device is equipped with a rectangular DMD, the corners do
not produce light to create the circular beam but it was still possible that for certain contents (darker images) the corners are slightly
visible and not really black. To avoid this and to create a really black area around the circular beam an iris is mounted in front of the
lens.
This iris can be adjusted from fully open to almost closed (± 1 cm remains open). When the projector is on, the small opening should
prevent overheating of the lens and the iris mechanism.

About EMP on/off
Before an EMP on/off command can be sent on channel 16, that channel 16 must be disarmed for at least 10 seconds.
So nothing will happens when sending e.g. combination Lamp On followed with EMP on/off . The status of the EMP will not change.
To change the status you should send the following combination : Lamp On – Disarmed for at least 10 seconds – EMP on/off .
