4. Introduction
cPRO PLUS hand unit cPRO hand unit cPRO ONE hand unit
The cPRO / cPRO PLUS hand unit is a 3-4 axis wireless hand-held control device for the cPRO
lens control system. The cPRO ONE is a 1-2 axis wireless hand-held control device. All 3 have
the red-coded cmotion radio module and share the same user interface, functions and features.
With their user friendly and intuitive interface, the cPRO / cPRO PLUS and cPRO ONE hand
units are lightweight and set new standards in both design and ergonomics.
The focus knob oers an ergonomic grip with a ngertip concave mold and mechanical hard
stops.
9 user buttons on the cPRO PLUS and 6 user buttons on the cPRO and cPRO ONE provide
quick access to cPRO’s extensive features. Illuminated key elements (focus marker ring, iris
slider strip and buttons) oer controllable ambient lighting for bright or dark environments.
The capacative touch display shows live lens and camera information.
The asymmetrical design and comfort grip keeps the hand unit balanced in your hand. Several
well positioned mounting points provide options for third party accessories including quick
release mounts, monitors, etc.
Up to three cPRO / cPRO PLUS or cPRO ONE hand units can connect to a cPRO motor /
cPRO camin wirelessly for split focus, iris and zoom operation. Real-time lens data is available
when used with the cPRO motor / cPRO camin.
Using the LBUS interface, the cPRO / cPRO PLUS or cPRO ONE hand unit can be hard-wired
with up to four additional cforce motors and other ARRI / cmotion control units including the
pan-bar / steady zoom, ARRI LCUBE-1, LCUBE-2, ARRI Master Grips or cnder III.

4.1. LBUS connector
LBUS is a bus standard designed to allow multiple lens motors and control devices to
communicate with each other. Up to four 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. For hard-wired operation the cPRO / cPRO PLUS or cPRO
ONE hand unit can be connected to the daisy-chain through its LBUS interface using any
LBUS to LBUS cable.
4.2. CAM interface
The cPRO / cPRO PLUS and cPRO ONE hand units are equipped with an LBUS connector
but do not have integrated CAM connectors. However, the CAM interface on the cPRO
motor / cPRO camin is also a fully functional LBUS connector. As such, it allows multiple
lens motors and control devices to communicate with each other through K2.0015760 Cable
CAM (7p) - LBUS. Using this cable the cPRO / cPRO PLUS or cPRO ONE hand unit can also
be connected to the daisy-chain through its LBUS interface for hard-wired operation.
In addition, the CAM interface on the cPRO motor / cPRO camin oers a versitile interface
for camera control. There are several camera interface cables available which, depending
on the camera, oer start-stop control with feedback, camera status, tally and even camera
control. (License required to control camera settings / available with Software Release
Package v3.0 or higher).
If a camera is detected in the LBUS daisy-chain, camera data and camera feedback will be
displayed on the cPRO / cPRO PLUS or cPRO ONE hand unit.

5.2.2.1. Mechanical hard stops
The cPRO knob has two mechanical hard stops which can be adjusted freely around the
knob barrel. The hard stops allow you to move the knob between two focus positions
precisely.
In oder to adjust your long focus distance
- match the desired long focus distance position to the datum line of the knob
- open the thumbscrew on the upper hard stop and slide the hard stop around
the knob barrel until it hits the panic button.
- lock the hard stop position by turning the thumbscrew clockwise
In oder to adjust your close focus distance
- match the desired close focus distance position to the datum line of the knob
- open the thumbscrew on the lower hard stop and slide the hard stop around
the knob barrel until it hits the panic button.
- lock the hard stop position by turning the thumbscrew clockwise
5.2.2.2. Panic button
The cPRO panic button is a unique feature of the cPRO / cPRO PLUS and cPRO ONE hand
unit. It allows you to override the mechanical hard stops without adjusting the predened
focus range. E.g. when shooting the slate outside of the predened focus range, or the
actor misses their mark.
In order to override the mechanical hard stops temporarily, simply press the panic button
and rotate the knob so it passes under the hard stop.
In order to disable the mechanical hard stops, press and turn the panic button clockwise
or counter-clockwise 90°. To re-enable the mechanical hard stops, press and turn the
panic button back to its home position.
