{Expand}, or {Calibrate} button.
Note: To access these softkeys at any time, press down on an encoder.
Home
Each parameter has an associated {Home} key in the encoder LCD. This accesses any parameter and
returns it to its default position. Additionally, the control keypad has a [Home] key located below
[Sneak]. See Home (on page172)for more information.
Min and Max
{Min} and {Max} are displayed when the parameter is linear, such as a shutter. Use these keys to set a
minimum and a maximum setting for a parameter.
Next and Last
{Next} and {Last} are displayed when the parameter is segmented such as a fixed gobo or color wheel
or a color scroller. Use these keys to increment or decrement in full frames.
Mode
The {Mode} key is provided to select different modes for the encoder wheel such as rotate, index, or
special effects.
When more than two modes are available, the {Mode} key can be pressed repeatedly, advan-
cing through the various modes. Each mode will display beneath the current parameter set-
ting.
When only two modes are available, the alternate mode is indicated instead of a {Mode} key.
Toggling that button switches the encoder wheel to the alternate mode.
Expand
Some parameters will have an {Expand} button, which indicates that this parameter has “Expanded”
functions. When that button is pressed, the display repaints to display all the media settings available
for the specific wheel.
Flip
The {Flip} button, as displayed in the Pan/Tilt section of the encoder LCD, is used to flip the unit into
its exact same position, but from the other direction. Depending on the current values of pan and
tilt, there may be multiple flips.
This allows you to correctly focus a fixture that may be at the end of its pan or tilt range or to correct
a fade that may be moving in an undesired direction.
The following example illustrates the use of {Flip}:
[channel list] {Flip}
Trackball On/Off
The {Trackball On/Off}, as displayed in the Pan/Tilt section of the encoder LCD, is used to give pan
and tilt functionality to a mouse or trackball device.When this function is turned on, above the CIA
will be a message saying “Cursor as Pan/Tilt”.
