Fixture setup
17
Manual control
The
MANUAL CONTROL
menu lets you reset the MAC Aura PXL and operate the fixture without a DMX
controller. To execute commands in the
MANUAL CONTROL
menu, select a menu item for the effect that
you want to control, then enter a value from 0 to 255 to apply a command. The menu items and values
correspond to the commands listed in the DMX protocol on page 22.
Service utilities
The control panel
SERVICE
menu provides utilities for technicians rigging or servicing the fixture:
•
ERROR LIST
displays any error messages that are stored in internal memory.
•
FAN CLEAN
lets you set all cooling fans to run at maximum speed for short periods for cleaning
purposes.
•
PT FEEDBACK
lets you disable feedback to the fixture software from the pan, tilt and effects positioning
systems. If feedback is set to
ON
and a pan, tilt or effect position error is detected, the shutter closes and
the effect resets. This feature can be disabled by setting feedback to
OFF
.
The
OFF
setting is not saved when the fixture is powered off, and the system will be re-enabled the next
time the fixture starts. If a pan/tilt position error occurs and the system cannot correct pan/tilt position
within 10 seconds, feedback is automatically disabled.
•
ADJUST
lets you set the pan and tilt home positions in the unlikely event that the fixture loses pan and tilt
adjustment. Adjustment may also be required by some firmware updates. If so, this will be mentioned in
the firmware release notes.
•
CALIBRATION
lets you set new default positions for calibration purposes, set effects to their factory
default positions or overwrite the factory default positions with new values. See ”Calibration” below.
•
USB
lets you updates the firmware (fixture software) using a USB memory device. For a detailed guide to
updating the firmware, see ”Installing using a USB memory device” later in this chapter.
Calibration
Martin fixtures are adjusted and calibrated at the factory, and further calibration should only be necessary if
fixtures have been subjected to abnormal shocks during transport or if normal wear and tear has affected
alignment after an extended period of use. You can also use calibration to fine-tune fixtures for a particular
location or application.
The
CALIBRATION
menu lets you define offsets in the fixture software to adjust the positions of pan, tilt and
effects relative to the DMX values the fixture receives. This allows you to fine-tune fixtures and achieve
uniform behavior in different fixtures.
Calibration can be carried out using the fixture’s onboard control panel and via DMX (see ”Changing
calibration offsets using DMX” on page 20).
A recommended procedure is to set pan, tilt and effects to the same DMX values in multiple fixtures and
then calibrate each fixture using its onboard control panel while comparing its light output with a reference
fixture. The calibration range available for each effect varies. Calibration values are expressed as
percentages. After selecting a value, press Enter to set the effect to that value.
Loading and storing default calibration offsets
In the
SERVICE
→
CALIBRATION
menu,
LOAD DEFAULTS
lets you erase the calibration offsets that you
have defined and reload the default calibration offsets that are stored in memory
.
SERVICE
→
CALIBRATION
→
SAVE DEFAULTS
lets you overwrite the factory default calibration offsets
that are stored in memory with any new offsets that you have defined. Overwriting is permanent, so once
you have saved new default offsets,
LOAD DEFAULTS
will load the new defaults, not the original factory
defaults.
