Technical information

The HU3 supports 3D operation with control for both 3D rigs and stereo lenses. Lens

Tweak software compensates for differences between the stereo lenses so that they track

accurately across their range.

3D rig software allows the HU3 to control rigs in any of the common configurations,

beamsplitter or side-by side. Calibrations for up to five rigs can be stored in the HU3. The

display shows convergence angle and Interaxial (Interocular) separation. The axes can be

interlocked so that the convergence distance is kept constant which changing the

Interaxial separation. The convergence distance is read directly off the focus ring.

C. The zoom function is implemented by a Micro Force control. It can be directly

connected to the Hand Unit using a bracket or operated remotely using a cable. The

camera may be started either from the Micro Force or from the Hand Unit.

D. The Remote Iris Box provides a separate control for the Iris function. It is automatically

enabled when plugged into the Iris accessory connector on the Hand Unit.

E. Optional wireless units allow various lens and camera control functions to be split off

from the Hand Unit functions. The Focus-Iris unit is a single channel hand control. When

active, it takes over either the focus or iris function from the Hand Unit. The F/X unit adds

camera speed ramps with iris and/or shutter compensation as well as recording and

playback functions. The Radio Micro Force module allows the zoom function to be split off

from the Hand Unit.

F. The Motor Driver (MDR2) supports 3 motor channels, camera run/stop, and camera

speed and shutter control. It controls the speed and shutter angle over all of the major film

cameras in use today that support external control. The 30 channel transceiver allows the

simultaneous operation of both the Hand Unit 3 as well as the optional wireless hand

units listed previously. An integral voltage booster allows for operation over a voltage

range of 11 – 28 VDC. Switches are provided for adjusting Motor Torque and reversing

direction.

Special 3D software for the MDR2 allows a single HU3 to control a pair of motor drivers for

controlling a stereo lens pair.

G. DM-1X, DM-2, and DM4 cover requirements from the largest zoom lenses to small lenses

primes. They have proven their toughness under extremes of temperature, humidity and

vibration. All of them use hardened metal gears with super-hard coatings to give very low

backlash over thousands of hours of operation.

II. FI+Z Basic Operation Summary.

A. Set-up the Motor driver (MDR2) and Digital Motors.

a. Slide the motor brackets onto the matte box support rods. Position the motors and

brackets so that the motor gears mesh with the corresponding lens gears.

Couple

the lens motors to the lens gears

. Adjust the motors to have minimum backlash and

tighten the handles of the motor brackets. Do not couple the motor to the lens too

tightly or binding will result. Check that the motor brackets do not flex or slip on the

matte box support rods. For normal lenses, the Torque adjustment switches can be

set in the middle position of their range. Connect the motor cables from the motors

to the MDR2.
