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
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.
