rotation speed are selected on channel 5 (channel 7 in 16-bit Extended mode). Fine tuning of this index

position or rotation is available on channel 6 (channel 8 in 16-bit Extended mode).

The gobo wheel can also rotate continuously in both directions at variable speed.

FOCUS

The beam may be focused from approximately 2 meters (6.5 feet) to infinity using channel 7. 16-bit

Extended mode provides finer tuning on channel 5 of the color setting selected on channel 4.

ROTATING PRISM

The prism is controlled using channel 8 (channel 10 in 16-bit Extended mode). It may be inserted and

removed from the light path. It rotates in both directions at varying speeds.

PAN AND TILT

Head pan and tilt are controlled on channels 9 to 12 (channel 12 to 15 in 16-bit Extended mode). The

course control channel sets first 8 bits (the most significant byte or MSB), and the fine channel sets the

second 8 bits (the least significant byte or LSB) of the 16-bit control byte. In other words, the fine channel

fine-tunes the position set by the course channel.

Speed control

TRACKING CONTROL

Tracking control for pan/tilt and the various effects is enabled by setting the speed channels, respectively 13

and 14 (channels 16 and 17 in 16-bit Extended mode) to 0.

With tracking control, the speed at which effects move is determined by the cross-fade time between two

positions or scenes. The controller divides the move into steps and updates the fixture with small changes

at the rate required to achieve the fade. The fixture “tracks” the changes and averages them with a digital

filter algorithm to provide smooth movement.

VECTOR CONTROL

Alternatively, with vector control, movement speed is determined by the speed values on channels 13 and

14 (channels 16 and 17 in 16-bit Extended mode). This provides a way to control speed on controllers

without cross-faders. Vector control also provides smoother movement, particularly at slow speeds, with

controllers that send slow or irregular tracking updates.

When using vector control, the cross-fade time must be 0.

BLACKOUT

When “blackout while moving” is selected on channels 13 and 14 (channels 16 and 17 in 16-bit Extended

mode), the shutter closes when the effect moves to make the transition invisible. The shutter opens when

the movement is complete.

PERSONALITY OVERRIDES

Channel 13 (channel 16 in 16-bit Extended mode) provides tracking values that allow you to override the

pan/tilt speed personality setting (PTSP in the control menu). Channel 14 (channel 17 in 16-bit Extended

mode) provides tracking values that allow you to override the shortcuts setting (SCUT in the control menu).

See the DMX table for details.
