Adjusting settings via DMX
Certain fixture settings and parameters can be adjusted from the DMX controller on the fixture
control/settings channel, DMX channel 33.
Commands sent on this channel override any settings previously entered in the fixture’s onboard control
menus.
To help you avoid accidentally applying a setting that may disrupt a light show, for example, most of the
commands must be held for a certain time before they are applied. For example, the command that turns off
the display illumination must be held for one second to activate it. The command that resets the fixture must
be held for five seconds to activate it. The times required to apply DMX commands on the Fixture
control/settings channel are listed for each command on page 24 in the DMX protocol.
Resetting
Either the entire fixture or individual effects can be reset to their initial positions. Resetting individual effects
can allow on-the-fly recovery if an effect loses its correct position, for example, without having to reset the
entire fixture.
Settings
A range of fixture personality and behavior settings can be adjusted via DMX, overriding any settings
previously entered in the onboard control menus. See DMX channel 33 in the DMX Protocol on page 21 for
a full list of the settings available for adjustment via DMX.
Illuminating the display
Among the useful features on the fixture control/settings channel is the fixture display setting. The fixture’s
display panel can be brought out of sleep mode with a DMX command. This makes it possible to read the
fixture’s DMX address while the fixture is installed in the rig.
After being illuminated in this way, the display will return to sleep mode according to the setting entered in
the onboard control menus.
Changing calibration offsets using DMX
The Fixture control/settings DMX channel allows pan, tilt and zoom to be calibrated by changing their
factory default offsets in percent values from the DMX controller.
To set an effect offset:
1. Set the effect you want to calibrate to a specific value via DMX (for example, set all the fixtures in a
group to DMX value 200 on the zoom channel).
2. Select ‘Enable calibration’ on the Fixture control/settings channel and hold for 5 seconds to activate.
3. The DMX control channels for pan, tilt and zoom now adjust the calibration offsets for those effects.
Adjust each offset until the effect is in the required position (for example, adjust the zoom offset on each
fixture in the group until the beam angle on all fixtures is identical – this is the position you will obtain
when you send DMX value 200).
4. Send a ‘Store ...’ command for the effect on the Fixture control/settings channel and hold for 5 seconds
to activate. Calibration offsets are now stored in memory and normal DMX control is restored.
Calibration offsets that are stored in memory are not affected by powering the fixture off and on or by
updating the fixture software.
You can reset all calibration offsets to their default values by sending a DMX value on the Fixture
control/settings channel. You must hold the value for 5 seconds. The fixture will return to factory default
calibration values. If you have overwritten the factory default values by applying a CALIBRATION
→
SAVE
DEFAULTS command in the SERVICE menu, the fixture will return to the last default calibration values that
were saved).
