Chapter 12:
Fixture Motion Functions
This chapter describes mechanical control for the DL.2 fixture with it’s
internal projector.
Pan and Tilt
The DL.2 fixture has 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.2 fixtures, (see MSpeed
(Motor Speed) on page 120). To control Pan and Tilt movement timing via a DMX controller
crossfading, leave the Pan/Tilt MSpeed in it’s default Off setting.
Note: The DL.2 fixture uses 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
The DL.2 fixture has 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).
