Section 3 — Control Surface Description
Joystick
The Zodiak system Joystick is a precision three-axis device. Moving the
Joystick towards or away from you controls the Y-axis, moving the Joystick
left and right controls the X-axis, and rotating the Joystick controls the Z-
axis (
Figure 83 ).

Joystick Button
The Joystick button on the top of the Joystick can be used to accelerate the
change of the delegated parameter, to allow quicker placement on the
screen.
The
Joystick
button is also used to pick a backing color when auto setting up
a chroma key.
Joystick Delegation
Because the Joystick acts as a positioner for many different functions, mul-
tiple stages of delegation can be required to access and control a specific set
of parameters. Different types of delegation are available, depending on
the parameters being controlled. Delegations are made by selecting indi-
vidual buttons in separate delegation button groups. The individual Joy-
stick delegation buttons are discussed in detail later in this section.
The Joystick subpanel delegation buttons have three tally levels, corre-
sponding to the condition of that delegation. A lit button indicates the
current delegation. If the delegation is valid, the button will high tally. If the
delegation is invalid, the button will low tally (delegated but not active).
Low tally can occur if you attempt to delegate the Joystick to a resource like
a Transform Engine that is not present. Low tally can also occur when the
Joystick is delegated to multiple points of use.
