Parameter Descriptions
Individual parameters are described in the following sections.
Note: All DMX values indicated in the detailed parameter descriptions are in
decimal units.
Positioning Parameters
Fixture Pan and Tilt
The SHAPESHIFTER fixture has a 630° pan range and a 270° tilt range. Two DMX channels
provide 16-bit adjustment to a fraction of a degree for pan and tilt position.
An MSpeed function is available for
Pan
and
Tilt
parameters when the MSpeed parameter. For
information on implementing MSpeed, see
MSpeed (Motor Speed)
on page 41.
Note:
Optical encoders for pan and tilt 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, the fixture “times out” to
prevent wear on the motors. If the fixture has timed out, remove the
obstruction and home the fixture to return it to normal operation.
Module X and Y Position
In addition to fixture positioning, you can control the six outer LED
modules’ positioning. Each outer modules is capable of shifting 36°
(18° either side of the nominal position) in both the X and Y
direction.
In Reduced protocol, the six outer
modules are positioned as a unit. The
Master LED Function
channel allows you
to enable all of the LED modules when the
DMX value = 0-127 or disable the center
Module when the DMX value = 128-187.
In Expanded protocol, the
Master LED
X/Y Function
let’s you enable X/Y
positioning for all the modules as a unit
with a DMX value = 0-127 or enable
Independent X/Y Control with a DMX
value = 128-187. With Independant X/Y
control enabled, you set the module
position using the
X
and
Y
parameters
associated with each of the seven
modules.
