Dim

SHAPESHIFTER fixtures provide 16-bit brightness control utilizing the Dim Coarse and Dim Fine
parameters. The dim values range from Off at a DMX value = 0 to fully on when the DMX value =
255 for both parameters.

MSpeed (Motor Speed)

MSpeed is the time required for a motor to complete movement when changing from one position
to another. In SHAPESHIFTER fixtures, MSpeed provides a means for Pan and Tilt motors to reach
their target position at the same time, even though each motor may have different distances to
travel. MSpeed movement is extremely smooth because the fixture controls movements
independent of DMX refresh rates.
MSpeed times vary from 0.15 seconds to 252.7 seconds. However, when MSpeed is applied to a
parameter, the delay value (length of time allowed for the entire scene) needs to be longer than
the MSpeed value to allow the motors to complete their movement before the end of the scene.
An MSpeed value that is longer than the delay value could produce an undesirable result; for
example, no light output during the scene. For a listing of exact MSpeed times, see Chapter A:
MSpeed Conversion Table on page 57.
