Thirty channels (0-29) selected by up/down buttons are split into two sets. The first includes the spread-spectrum coding used in the MDR3.
The Preston DM1X Digital Motor is compatible with Preston MDR-4 motor drivers, the Digital Micro Force and the single-channel Video Lens Control. The motor housing is machined from a solid bar of Magnesium alloy and is coated with a special ceramic before painting for resistance to salt spray and moisture. The DM-1X features gears coated with Diamond-like Carbon (DLC) to provide toughness and efficiency.
The motor can be mounted to a variety of swing-arm brackets with conventional 15mm rods or directly mounted to matte box support rods with the Integral Motor Mount (sold separately).
The Preston MDR-4 improves upon Preston’s MDR-3 potential to provide lightweight wireless connectivity to your gimbal, drone or small camera configurations. The unit is designed to interact with lens control systems like the Preston FI+Z hand units and the LR2 Light Ranger. The MDR-4 device offers a built-in antenna (unlike the MDR-3 which attaches to the exterior), two sets of 30 channels, plus a reset button. It also provides a serial connector for LR2 & Cinetape, with no interface units required, and an analog connector for Canon and Fujinon video-style lens controls or for Microforce/broadcast zoom controls.
Thirty channels (0-29) selected by up/down buttons are split into two sets. The first includes the spread-spectrum coding used in the MDR3. The Blue Dot upgrade in the second set harnesses advanced coding to remove interference from adjacent channels.
There are a few helpful devices which allow you to keep an eye on specific statuses with a glance. Simple push buttons facilitate a switch in motor direction while an LED on/off light indicates which direction is in use. Also, a tri-color LED provides status on the torque level which can be modified via switches near the LEMO connectors.
Power the MDR-4 via an 11-32 VDC power connector or with an R/S camera connector (ARRI, RED, Sony, and more) as an alternate.
Use the Wooden Camera MDR4 Mount accessory to attach your Preston MDR-4 to a RED or ARRI camera.
