Use the versatile ARRI UMC-4 LDS Universal Motor Controller to remotely control focus, iris, and/or zoom, and to record lens metadata for post and VFX use. The UMC-4 Controller can govern up to three lens motors, and is compatible with WCU-4, SXU-1, Master Grip, and ARRI zoom controls. This controller is compatible with any ARRI or third-party pro camera, and with CLM-3/4/5 lens motors.
The downloadable SUP 2.0 update for the UMC-4 adds several key functions like wireless lens-file transfer, the ability to set and display your gear motor teeth-count (for correct lens data), support for the cmotion cfinder III, and improved motor characteristics. AMIRA/ALEXA Mini–specific updates include full playback control, selection of user setups, and a PLAY/ERASE status display. An updated LDA (lens data archive) is detailed below in the Features section.
This standard version of the UMC-4 includes two serial ports; optional modules are available separately for linking the UMC-4 to Canon and Fuji focus/zoom controls. The UMC-4’s internal timecode clock can be jam-synced, or it can be used to output LTC timecode. The included SD card can be used for recording lens data and timecode, and for updating the controller’s firmware. The UMC-4 motor controller features a 2.4″ LCD display, a water-resistant design, and a durable, outdoor antenna.
