6. Keystones
If an image output from the Robin ProMotion is at an angle, the image may be skewed.
Two keystone channels (Keystoning Vertical, Keystoning Horizontal) in DMX chart adjust the image shape, aspect
ratio is kept. Default DMX value for both channels is 128, it means that no keystone correction has been used.
The channel " KeyStoning Vertical" turns image along X-axis.
The channel " KeyStoning Horizontal" turns image along Y-axis.
The keystone values can also be used to create interesting skewing effects.
The option "Save AutoKeystoning" from DMX chart (channel Special functions, range 230-234) allows you to
save adjusted values of the keystone channels and correct them automatically when head position is changed:
First use the Keystoning Vertical channel and the Kyestoning Horizontal channel to adjust image shape, after
that go to
"Save AutoKeystoning" and stay at this DMX range for 3 seconds to write keystoning values into
memory. To activate AutoKeystoning, set channels Horizontal and Vertical Keystoning to 0. Now, if you move
the fixture head on another place in the same plane, the image shape will be automatically corrected.
If you move the head in a tilt into opposite position, the image shape will be automatically corrected again and
the image will not be turned:
Note: DMX keystone channels 9/10 (Keystoning Vertical/ Keystoning Horizontal) can be used for both HDMI
inputs - internal and extenal.
