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 is for use by Martin® Service and its authorized agents only.
• 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 firmware using a USB memory device” later in this chapter.
Calibration
Martin® fixtures are adjusted and calibrated at the factory, and further calibration will normally only be
necessary if fixtures have been subjected to abnormal shocks during transport, 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
zoom 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 ”Illuminating the
display” on page 15).
A recommended procedure is to set pan, tilt and zoom 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.
Firmware installation
The currently installed firmware (fixture software) version can be viewed in the control panel INFORMATION
menu. Firmware updates are available from the Martin® website and can be installed using a USB memory
stick or a Windows PC running the Uploader application in the Martin® DMX Tools suite (available for
download free of charge from www.martin.com) and a Martin® M-DMX compact USB-DMX interface.
Calibration data is stored in the relevant modules wherever possible so that a module will stay calibrated if is
removed from the fixture or installed in another fixture.
