Adjusting settings via DMX 15
Adjusting settings via DMX
Certain fixture settings and parameters can be adjusted from the DMX controller on the Fixture
control/settings channel.
Commands sent on the fixture control channel override any settings 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 23 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.
Illuminating the display
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.
Control menu setting overrides
The following fixture settings can be adjusted via DMX, overriding the settings entered in the onboard
control menus. See under “Control panel menus” on page 26 for details of these settings.
• Dimming curve
• Pan and tilt speed
• Effect shortcuts
• Video tracking
• Focus tracking
• Cooling mode
• Pan/tilt and zoom calibration offsets
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 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.
