ORACLE OVERVIEW
This section will cover the basic functions
of the ORACLE and what each button and
dial controls in the system.
a. Backlit LCD screen
The LCD screen displays menu options and
current status of the ORACLE. Below is a
sample of the home screen and values.
1. 2. 3.
4. 5. 6.
1. MAX SPEED value (28 - 1000) see g.
2. DAMPING in seconds (.055s -
2.55s) see h.
3. DEADBAND mode (LIN or LOG) see i.
4. Current Joystick Y speed value (+/-)
5. Current Joystick X speed value (+/-)
6. LIN/LOG value (0-99 in LIN mode
and 99-0 in LOG mode).
To access child menus from the home
screen, press the
MENU button ( b. ) on the
ORACLE.
b. MENU Button
The MENU button is used to call up the
ORACLE menu when on the home screen. It
can also be used to escape back to parent
menus and cancel changes when altering
settings in the ORACLE options.
c. ENTER Button
The ENTER button is used to save settings
when making changes to the ORACLE
options. Alternatively, the center
JOYSTICK
BUTTON ( j. ) can also be used in most cases.
d. e. f. Memory banks 1, 2, and 3
The ORACLE has 3 memory banks for
storing and playing back camera moves.
Each bank can be cleared by holding the
corresponding button down for 5 seconds.
The
1, 2, AND 3 BUTTONS can also be used
to select their corresponding menu options
when navigating the ORACLE settings
menus.
For more information on recording and
playing back camera moves, reference that
section in this quick start guide or in the
ORACLE manual.
g. MAX SPEED control dial
This dial is used to control the maximum
speed of the elektraDRIVE motors. The value
is adjustable from 28 (being the slowest) to
1000 (being the fastest) and is displayed
in the left column of the top row on the
home screen. For the sliders, these values
are arbitrary and will vary depending on the
which series of motor you are using. Adjust
and test as needed to achieve the speed
required.
This dial can be adjusted in real-time during
a camera move to ramp speed up and down.
These values are also recorded if creating a
recording to one of the memory banks.
h. DAMPING control dial
This dial is used to control the damping
of the elektraDRIVE motors. The value is
adjustable in seconds from .055s to
2.55s and is displayed in the center
column of the top row on the home screen.
Damping is the amount of time the motor
takes to achieve maximum speed (
g. ). This
helps smooth the motion of moves.
A low value will make the motor jump to full
speed quickly creating snappy moves.

A higher value will slowly ramp the motor
up to speed and then back down when the
joystick is released.

High (2.55s) Damping
This is useful when wanting to create very
smooth moves with gradual start and stop
motions.
Select the time frame you want in seconds to
determine how much damping is applied to
the motor start up and shut down.
i. DEADBAND control dial (LIN/LOG)
The DEADBAND dial controls the sensitivity
of the joystick. The values can be adjusted
from 0 - 99 in LIN (linear) mode and 99 -
0 in LOG (logarithmic) mode.
Deadband is the circle of travel from the
center of the joystick before power is sent to
the motor(s).
Low DEADBAND setting.
Full range of joystick sensitivity.
High DEADBAND setting.
Limited range of joystick sensitivity.
In LIN (linear) mode, 50% travel of the
joystick equates to a 50% increase in
speed. By adjusting the LIN value, you
can increase and decrease the sensitivity of
the joystick. Higher numbers will make the
joystick less sensitive toward the middle.
Any remaining travel of the joystick will be in
linear values.

In LOG (logarithmic) mode, the movement
of the joystick has an exponential effect on
the speed of the motors. In this mode, the
first 50% of joystick will increase power from
0 to approximately 10% on the motor(s).
The remaining 50% of joystick will increase
speed from approximately 11% to full power.
