Auto-Image Rotation and Pan Position
The MMS100 has an Auto-Image Rotation feature built into the graphic server. This feature uses the commanded pan
position to rotate the image as the mirror is moving. This rotation is necessary due to the folded optical path the projected
image follows. There are multiple modes that the Auto-Rotation feature can function, see chart below. The effect is
accessed via a global effect channel set to 158
In addition to the effect modifiers for control of the auto-rotation feature, there is the necessity to determine the auto
rotation direction. This setting accounts for the fact that a MMS may be attached with mirror facing 'UP' or mirror facing
'Down' with respect to the attached projector. This setting is found in the CMA and can be set to 'Clockwise' or 'Counter
Clockwise'
Auto-Image Rotation Pan Position.
Note:On the Hog controller, this effect can only be used as global effect 2, 3 or 4.
