Chapter 14:

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 14-180). 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).
