Introduction 11
4 Introduction
ARRI and cmotion have partnered up to develop the new intelligent cforce
mini RF motor.
The ARRI cforce mini RF is an intelligent lens motor with integrated white-
coded ARRI radio module, eliminating the need for an additional receiver unit
mounted on the camera.
The cforce mini RF can pair with up to three hand units for split focus, iris and
zoom operation and provides full lens data when used with the WCU-4 hand
unit.
The simple user interface includes two soft buttons and a display for setting
the motor axis, triggering motor calibration and selecting one of the 14 radio
channels.
Using the LBUS interface, the system can be expanded with up to two
additional cforce motors while the new CAM connector provides a versatile
interface for power supply and run/stop control for cameras including ARRI,
Red, Sony, Canon and Blackmagic.

12 Introduction
Main features
Integrated white radio module
Supports lens data with WCU-4 hand unit
Daisy-chainable via LBUS
Small and lightweight (~186g/6.56oz incl. gear and antenna)
Compatible with all hand units containing ARRI’s white-coded radio
module
4.1 LBUS
LBUS is a bus standard designed to allow multiple lens motors and control
devices to communicate with each other. Up to three cforce-type motors can
be chain-linked in a row. Each cforce motor has two identical, bi-directional
LBUS interfaces providing power and control signals to the motor.
