Fixture Motion Functions
This chapter describes mechanical movement control for DL.3 and DL.2
fixtures.
Pan and Tilt
DL.3 and DL.2 fixtures have a 400° pan range and a 240° 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 DL.3 and DL.2 fixtures, (see
MSpeed (Motor Speed) on page 242). To control Pan and Tilt movement timing via a DMX
controller crossfading, leave the Pan/Tilt MSpeed in its default Off setting.
NOTE: DL.3 and DL.2 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.
Dimmer
DL.3 and DL.2 fixtures have a mechanical iris located in front of the projector output lens that
functions as a dimmer for the fixture’s output. This feature gives the operator the ability to fully
shutter the output and eliminate the residual luminance from video black. The Dimmer
parameter controls the dimming iris adjustment from closed (DMX value = 0) to fully open
(DMX value = 255).
Focus
The Focus parameter controls the fixture’s mechanical focus from near (DMX value = 0) to far
(DMX value = 255).
Zoom
This Zoom parameter controls the fixture’s mechanical zoom from narrow (DMX value = 0) to
wide (DMX value = 255).
