PRESTON FIZ3 LENS CONTROL MDR-2 SYSTEM
The FI+Z system controls the complete array of both lens and camera functions. The system is modular, giving the user a wide range of choices from a basic cable connected system to a full wireless microwave system. The System consists of the Hand Unit, Motor Driver, Digital Motors, optional Microwave Link, cables and motor mounting bracket.
The heart of the system is the Hand Unit. Its robust construction, ergonomic design and quick set-up have all contributed to its position as the "industry standard". It's carefully machined exterior matches the phenomenal precision offered by its advanced digital architecture. The unit provides 16 bits of position resolution - 1 part in 64,000 - for incredible smoothness. A bright bargraph display shows the position of the zoom lens. A "Snorkel Mode" enables electronic Pan and Horizon control of Snorkel lenses.
The zoom function is implemented by a Micro Force control. It can be directly connected to the Hand Unit using a bracket or operatedremotely using a cable. The camera may be started either from the Micro Force or from the Hand Unit.
A unique scale adjustment system makes set-up extremely quick. Any portion of the lens focus, iris, or zoom range may be expanded tothe full-scale range of the corresponding control knob with the touch of a switch. In the case of zoom, electronic limit stops can be set. An optional Remote Iris Box provides a separate control for the Iris function. It is automatically enabled when plugged intothe Iris accessory connector on the Hand Unit.
The Motor Driver MDR2 (shown below with the microwave transceiver) interfaces the FIZ Hand Unit with the DM-1, DM-2, and DM-3 digital motors. It provides 3 channels of motor drive, the camera run function for film cameras and the VTR function for video cameras. In addition, it allows wireless control of both the camera frame rate and shutter angle when used in conjunction with the F/X box.
The unit automatically calibrates the motors to the mechanical end limits of the lens. Each of the three channels has a separate three level torque limit selected by a switch.
The power requirements of the MDR2 are 24 - 30 VDC at .15A quiescent, 3A peak (all 3 motors stalled. When fitted with the Microwave transceiver, the operating voltage range is extended from 12 - 30 VDC input.
