Calibrating Effects Via Dmx - Martin MAC One User Manual

Overwriting factory default calibration values
It is possible to overwrite the factory-set calibration values and replace them with the currently defined
calibration values, but take care when doing this. Please contact Martin Service if you have any questions
about making this change.
Important! Overwriting factory default calibration values with custom values is permanent. If you have set
a custom value and applied a CALIBRATION → LOAD DEFAULTS → SAVE command, you will not be
able to recover the original factory default value.
To overwrite the factory default calibration values:
1. Set new calibration values for the effects that you want to recalibrate by adjusting them as described
above.
2. Apply a SERVICE → CALIBRATION → LOAD DEFAULTS → SAVE command.
Deleting all factory default calibration values
It is possible to delete all factory-set calibration values and return all the fixture's calibration values to zero
using the DEFAULT SETTINGS → LOAD control menu, RDM or P3.
Important! Setting all the default calibration values to zero is permanent. You will not be able to recover
any of the original factory default calibration values once you have set them all to zero.

Calibrating effects via DMX

You can adjust the home positions of pan, tilt and all the fixture's effects remotely via DMX by setting
custom calibration offsets on the Control/Settings DMX channel. The DMX option has the advantage of
letting you calibrate multiple fixtures from the DMX controller when the fixtures are in position in the
lighting rig.
Setting calibration offsets
To set a custom offset in the position of an effect:
1. Set the effect 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 first fixture's Control/Settings channel and hold for 5 seconds to
activate.
3. The fixture now registers the current positions of all effects and holds them there. To select an effect
to adjust, you must first release it from its hold position by changing the value on its DMX channel by
+/- 10%. The effect then returns to its hold position. The effect's DMX channel now represents the full
calibration range. The range can vary but is typically +/- 5-10%. In this case you can adjust the effect's
position using that effect's DMX channel (8- or 16-bit) as follows:
• DMX value 0 = -5%
• DMX value 127/32767 = 0%
• DMX value 255/65535 = +5%.
4. Adjust the effect until it is in the required position (for example, adjust the zoom angle on each fixture
in the group until the angle on all fixtures is identical – this is the position that you will obtain when you
send DMX value 200).
5. Send a 'Store XXX calibration' command on the Control/Settings channel for each effect that you
adjust and hold that command for 5 seconds to activate. The new calibration offset is now stored in
memory.
6. When you have finished adjusting calibration offsets, send value 0 on the Control/Settings channel
and hold for 5 seconds to exit the DMX calibration procedure and return to normal DMX control. You
can now calibrate the next fixture.
Calibration offsets that are stored in memory are not affected by powering the fixture off and on or by
updating the fixture software.
