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 provides control over 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.
G. DM-1X and DM-2 digital motors provide the ultimate in power and reliability. They have
proven their toughness under extremes of temperature, humidity and vibration. Their
housings are machined from solid magnesium billets and protected by a special ceramic
coating before painting. This provides exceptional resistance to salt spray and moisture.
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.
b. Use the appropriate camera cable to connect the MDR2 to the camera accessory
receptacle. Please note that a special molded “Y” cable is required to control both the
speed and/or shutter angles of 24V Arri cameras (p/n #4535) and Panavision
Millennium (p/n #4537).
c. Connect the power cable from the MDR to the camera or battery power receptacle.
d. Apply power to the MDR2. Press the reset button. The motors will calibrate
themselves to the mechanical span of the lens rings.
