Chapter 5
Fixture Control
This chapter describes mechanical movement control for SHOWPIX™ and
StudioPix™ fixtures in all protocol modes.
Pan and Tilt
SHOWPIX fixtures have a 400° pan range and a 240° tilt range. StudioPix fixtures have a 540°
pan range and a 210° tilt range.
Two DMX channels for Pan and two for Tilt provide 16-bit position adjustment to a fraction of a
degree.
MSpeed values can control the timing of pan and tilt motion for SHOWPIX and StudioPix
fixtures. To control Pan and Tilt movement timing via a DMX controller crossfading, leave the
Pan/Tilt MSpeed in it’s default Off setting.
Note: SHOWPIX and StudioPix fixtures use optical encoders for pan and tilt
to instantly correct the fixture’s position if the fixture is jarred from its
programmed position.
If a physical obstruction prevents the fixture from correcting its position, this
correction feature “times out” to prevent wear on the motors.
If the fixture’s position correction has timed out, remove the
obstruction and home the fixture to return it to normal operation.
MSpeed (Motor Speed)
The MSpeed parameter adjusts the time required for a motor to complete movement when
changing from one position to another. MSpeed provides a method for all 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. In general, allowing the console to
crossfade the pan and tilt values for a SHOWPIX fixture is acceptable. However, extremely slow
movements may require the use of Mspeed instead of console crossfades. For a listing of exact
MSpeed times, see Appendix A: MSpeed Conversion Table on page 97.
