AdJ.
– Adjust default positions of yoke and effects. Occasionally, for
various reasons, the calibration of the moving parts within this fixture –
yoke, color wheels, effects wheel, zoom lens, and shutters – may become
slightly misaligned. You will know when this happens by looking at the
output of the fixture. If some of the apertures for the color wheel, effects
wheel, etc., are not centered in the beam correctly or if the default position
of the yoke is not where it should be, then the
adj. setting may be used
to remedy the problem. This setting allows you to make adjustments to
each parameter individually.
To adjust the default setting of a particular parameter:
1. Select the Adj. option from the SPEC function of the display
(see SPEC above).
2. Press the [ENTER] button.
3. Press the [UP] or [DOWN] button to select a parameter to
adjust. The options are: PAn , t!t , SPEd ( speed of movement),
CoL.o (color wheel), CYAn , MAGE (magenta), yELL (yellow),
CSPd (color change speed), MACr. (macros), EFEC (effects),
Z.oom (zoom), Stro. (strobe), and dimr (dimmer).
4. Press the [ENTER] button. The display will show the current
value in the range of 0 – 255.
5. Press the
[UP] or [DOWN] button to adjust the setting to the
desired value.
6. Press the
[ENTER] button.
7. After setting each parameter that needs to be adjusted, press the
[UP] or [DOWN] button until the display reads F.CAL .
8. Press the [UP] or [DOWN] button until the display reads A.rES .
The fixture will reset and the newly adjusted values will be written to
memory.
9. Press the [MODE] button twice to back out of the special
functions mode.
J. Setting the DMX512 Address
The DMX512 address for each fixture must be set in order for it to correctly
respond to a DMX512 controller. Each fixture uses a block of 16 DMX512
channels in order to control all of its attributes such as pan, tilt, color, etc. In a
system with multiple fixtures, each fixture should have a unique DMX512 address
and the starting DMX512 addresses of consecutively addressed fixtures should
allow for each 16-channel block of control channels. If, for example, four fixtures
are to be addressed and the first one has a starting DMX512 address of 001,
then the second should be addressed starting with 0017, the third, 0033, and the
fourth 0049.
