grandMA3 User Manual » Operate Fixtures » Encoder Resolution

Version 2.0

Sometimes precise handling is required, and you may want to change the resolution of an encoder.

The default encoder resolution of attributes can be defined from the user configuration menu:

1. ​Press Menu, tap Settings, and tap User Configuration. The user configuration menu opens.
2. On the left side of the window, tap Profiles.
3. Tap Edit Encoder Bar. The Default User Attribute Preferences menu opens.

It is also possible to change the encoder resolution directly on an encoder.

To do so:

1. Press and hold MA, this will display the possible resolutions in the channel function area of each encoder.
2. While holding MA, tap Link Resolution and select Single or FeatureGroup. Then tap the resolution area of an encoder; the encoder's selected resolution will change to the next resolution.
3. When the desired resolution is selected, release MA.

	Hint:
	- For one revolution, an encoder has 24 clicks. - 5 turns of an encoder are needed to cross the whole range of the attribute from its minimum to maximum.

The possible resolutions are:

1. Coarse: One encoder turn click will change the value depending on the readout:
   • Percent: 1
   • PercentFine: 1
   • Physical: (MaxValue-MinValue)/ (24*5)
     When multiple fixture types are selected, the smallest physical range of a fixture is taken to determine the size of one click. This allows having the same value change when for example, turning the tilt encoder.
   • Dec8: 255/(24*5), therefore 1 click equals 2.125
   • Dec16: 65 535/(24*5), therefore 1 click equals 546.125
   • Dec24: 1 677 216/(24*5), therefore 1 click equals 13 976.8
   • Hex8: 255 (=FF)/(24*5), therefore 1 click equals 2.125
   • Hex16: 65 535 (FFFF)/(24*5), therefore 1 click equals 546.125
   • Hex24: 1 677 216 (=FFFFFF)/(24*5), therefore 1 click equals 13 976.
2. Fine: Fine has a 10x finer resolution than coarse.
3. Increment: When the resolution is set to Increment, one encoder turn click will change the lowest digit of the displayed readout.
4. Native: The value Layers absolute and relative offer this mode to have direct access to the smallest possible value change of the parameter resolution.

	Hint:
	When Native mode is selected, if a dimmer channel is based on 8/16/24 bit, one encoder turn always results in a one digit change in DMX output.

 An encoder displays the current resolution in the center of the encoder symbol within the encoder bar:

Furthermore, the factors of value change between turning the inner encoder and all other encoder actions can be defined. See User settings for more information.

All factors can be selected from a list of predefined factors:
