To initiate the update, open the MRD2 update program on your PC. The program CD and a
serial cable is included with the MDR2. Remove power from the MDR2. Connect the serial
cable between the PC and MDR2 serial receptacle. Open the MDR2 update program. While
holding the reset button down, apply power to the MDR2. Release the reset button. The
program should now report that it has found a connection to the MDR2 and asks whether
you want to proceed with the update. Choose yes. After the program has completed the
update, you can remove the serial cable from the MDR2.
The serial receptacle is used for additional purposes:
• It can accept motion control commands from an external computer using
RS-232 data.
• It can accept data from the Panatape device using the Panatape interface
cable p/n 4534. The distance data is displayed on the Main Display screen.
V. Digital Motors
There are three types of digital motors used in the FI+Z system. All of the motors use
digital encoders to provide positional feedback to the MDR unit. Digital encoders are
highly reliable and do not suffer from wear.
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 DM-3 is specifically designed for use with snorkel lenses. It combines very high torque
and mechanical stiffness to smoothly drive the Pan and Horizon axes of the Revolution
Snorkel lens.
Step-up gears are provided to allow the DM-1X, and DM-2 motors to drive Panavision Zoom
and Iris gears as well as the Focus, Iris, and zoom gears of Canon and Fujinon video lenses.
Please consult our price list for a complete list of available gears.
VI. Camera and Lens Installation
The FI+Z system includes bracket kits to provide robust support when used in conjunction
with industry standard cameras. These brackets have been designed to for maximum
rigidity and lens positioning accuracy. All of the brackets have one 15mm opening for the
motor rod and one 19mm opening for a matte box rod or a step-down bushing for use
with 0.625” Panavision rods or 15mm Arri rods.
