I. Introduction A. System. The FI+Z system controls the complete array of both lens and camera functions. It consists of the Hand Unit HU3, one or more Motor Drivers, a set of Digital Motors, a Micro Force zoom control, and a variety of optional controls including wireless Focus/Iris, Zoom, and F/X units. B.
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.
b. Use the appropriate camera cable to connect the MDR2 to the camera accessory receptacle. (See pages 24, 25 for the cable list). Connect the power cable from the MDR to the camera or battery power receptacle. c. Apply power to the MDR2. Press the reset button. The motors will calibrate themselves to the mechanical span of the lens rings. d. Select the MDR wireless channel with the channel selection switches on the top cover. Set the slide switch on the MDR2 cover to Radio. B HU3 Set-up a.
e. To use a blank focus marking ring, turn off the Focus mapping: Press the Menu key. Select Lens. If the focal length and serial number of a lens appears to the right of “Lens”, press Fmap OFF. The HU3 is now ready for basic operation. The blank focus marking ring, and iris marking strip can be used to mark lens calibrations. f. Focus mapping eliminates the need to manually mark separate rings for each lens. Data from the lens library is matched to pre-printed focus marking rings.

Menu Screen Options. Press the MENU soft-key; the MENU screen appears. 3.
5. The Camera selection (Fig 1) provides for control of both camera speed and shutter angle for those cameras supporting remote operation. Pressing Choose brings up the Manufacturers folders (Fig 2). Pressing Choose again brings up the list of supported cameras (Fig 3). Fig 5.1 Fig 5.2 Fig 5.3 Press the left pad of the Nav key to return back to the Camera selection. Press the Set-Up key to bring up the camera Control menu (Fig 4).
To use a lens from the library, choose a lens folder shown Fig 6.4. Using the Nav key select the manufacturer (fig.6.5, the lens type (fig.6.6), and the lens (fig6.7) and press either OK or ENTER. Use the focus knob to set the lens to infinity as shown in Fig 6.9 and press NEXT/ENTER. The lens name now appears on the main screen (Fig. 6.9). Fig 6.4 Fig 6.5 Fig 6.7 Fig. 6.8 Fig 6.6 Fig. 6.9 To calibrate a new lens: Name the lens and store it in the lens library.
After the lens focus ring is set to infinity (FIG 17), the display indicates the first of ten calibration distances. There are two versions of this display screen, one for lenses with linear focus mechanisms, and a second for lenses with non-linear focus. Choosing a lens type automatically brings up the corresponding display screen. The display screen for lenses with linear focus mechanisms allow the user to scroll up and down with the Nav key (FIG 6.15, and 6.16). Fig 6.15 Fig 6.16 Fig 6.
The printed labels Ai - Ei are pictured below. Note that the midpoint of each scale is about twice the minimum focus distance. Although the ring can be chosen to cover the entire focus range of the lens, it is often advantageous to choose the ring which covers the minimum focus required for the actual shooting. Fig.23 Increasing the “throw” of the focus knob by choosing focus ring minimum focus. For example the Summilux 18mm lens has an 18” near focus, matching the Bi ring.
The Custom mode (Fig. 7.3) has two functions. The first allows the three MDR motor channels, focus, iris, and zoom to be assigned to user-designated Hand Unit controls. For example, in a multi-camera set-up, the focus knob of a single hand unit can be assigned to focus, iris and zoom, allowing the focus knob to control the focus rings of up to three separate lenses simultaneously. This mode is indicated by the icon C, (Fig. 7.5), displayed on the main screen. Custom Mode Fig. 7.3 Snorkel Icon Fig. 7.
Zoom Mode Set-Up Fig. 7.9 Fig 7.10 Fig. 7.11 To choose a Zoom Mode press the Set-Up key (Fig. 7.9). The Normal Zoom mode (Fig. 7.10) means that the Hand Unit controls the position of the zoom motor and this position is shown on the zoom bargraph display. Limits can be set to the zoom range using the Set/Reset keys. The Video Zoom mode (Fig. 7.11) allows the MDR to control lenses with integral servo units.
The OPTIONS (Fig. 8.6) selections consist of selecting distance units and knob direction. Use the Navigation key to select the desired function. The default knob direction is CW. Optional labels for the focus rings are available for CCW direction use. 9. The Zoom Bargraph indicates the position of the zoom when the zoom is in Normal mode (See section 7. Operating Modes.
Pressing the Fshow button switches the display from the remote distance measuring device (Fig. 11.1) to a dual display (Fig 11.2) and finally to the default display (Fig. 11.3). Fig 11.1 Fig. 11.2 Fig. 11.3 11. Software updates can be downloaded from the website http://www.prestoncinema.com/downloads.html. To load an update into the HU3: Install the boot loader program from the CD which is shipped with the FI+Z system to a PC. Make sure that the Hand Unit is not powered.
IV. MDR. Detailed Description MDR2: Torque and Direction Switches Channel Selector Switches MDR2 with 15mm rod bracket p/n 4335 and swing arm p/n 4302 The three channel Motor Driver (MDR2) is responsible for driving the motors, providing control signals to the camera, and transferring camera operating data to the wireless network through the transceiver module. The MDR2 uses a lens calibration sequence to determine the mechanical limits of the zoom, focus, and iris rings of the lens.
The Microwave Transceiver is located in the lid of the MDR2. It provides wireless bidirectional communication between the MDR2, Hand Unit, F/X unit and other clients in the wireless network. The lid also contains a voltage booster enabling MDR operation over an input voltage range from 11 to 30 volts. The wireless channels are selected by turning the two channel switches located on the MDR2 top cover. There are 30 channels numbered 0 – 29.
V. Digital Motors DM-1X p/n 4505 DM-1X p/n 4205A (integral bracket) DM2 p/n 4201A (integral bracket) DM4 p/n 4206 & 4206A both have integral brackets The DM-1X is a high speed and high power motor. It is specifically recommended for driving the focus ring of cinema lenses. The DM-2 is a smaller and lighter weight motor. It is recommended for driving the zoom and iris of all lenses, and the focus for all but very stiff lenses. The DM4 motor (right) is the smallest member of the family.
The swing arm has rosettes on two sides. This permits the motor to be mounted horizontally (above, left) or vertically (above, right). The two adjustable handles lock the rosette position and the motor bracket to the matte box support rod. Important tip: to prevent the motor position from changing as the handles are tightened, first tighten the handle which clamps the motor to the rod and then tighten the rosette handle.
VI. Camera and Lens Installation Digital motors can be mounted to matte box support rods with either the integral motor mounts as described in the previous section or with separate brackets. All of the brackets have one 15mm opening for the motor rod and one 19mm opening for a matte box rod. A step-down bushing is required for 0.625” Panavision rods or 15mm Arri rods.
