Preston MDR-4 Motor Controller

Control up to two digital motors and camera run/stop functions with G4 wireless link Preston hand controllers, such as our HU3, in a more compact form factor than the MDR-3. Serial port connects to the Light Ranger 2, transmitting distance information wirelessly to the HU4 and Video Interface unit. The MDR-4 automatically finds the span of the lens once each motor is plugged in, and each channel has its own three-level torque adjustment and direction switch to drive virtually any lens. The Analog port lets you plug a Micro Force or broadcast-style control directly into the MDR-4, controlling the motor of your choice as configured in the HU4 Mode menu.
