Universal Motor Controller UMC-4 – User Manual – V 02/2015 Page 11 of 54
Introduction
The Universal Motor Controller UMC-4 is an advanced 3-axis motor
controller. Up to three different hand units can connect to the UMC-4 at the
same time, controlling focus, iris and zoom on any camera. The intuitive
user interface helps to quickly setup the system and makes it easy to use.
The high-performance radio system offers reliable radio connectivity.
The UMC-4 incorporates the LDS Lens Data Archive and generates frame-
accurate lens data with any lens. Lens data is used for lens mapping to
pre-marked focus rings and depth-of-field display on the WCU-4 hand unit.
It also enables focus tracking – setting the focus motor to continuously
follow a subject by using an ultrasonic distance measurer. For VFX tasks in
post, the UMC-4 records lens data with timecode and inclinometer data,
helping match the virtual lens to the recorded image.
The UMC-4 supports internal and external timecode that is recorded with
frame-accurate lens data onto SD card, making the lens data usable for
postproduction. The internal timecode clock can be jam-synced from
external devices, but can output LTC timecode as well.
The UMC-4 includes multiple interfaces for maximum flexibility on set. Two
serial interfaces connect peripheral equipment such as ARRI’s UDM-1
distance measure. Optional connector modules interface directly with focus
and zoom demands from Fujifilm and Canon. An Ethernet connector
integrates the UMC-4 with standard IT equipment.
The UMC-4 is splash-proof and embodies the reliability and durability for
which ARRI is famous. The worldwide ARRI Service network ensures rapid
second level support if needed. New firmware versions can be installed to
the unit by means of an SD card.
Visit www.arri.com/ecs/umc-4 for up-to-date product information and
software updates.

QUICK START GUIDE
This quick start guide walks you through setting up the UMC-4 with one
hand unit and three motors for wireless lens control.
Mounting on Camera
Mount the UMC-4 on the camera, preferably in a vertical position by using
the L-Bracket, with the antenna pointing upwards and the motor connectors
pointing towards the lens. Such a position is necessary for the generation
of valid tilt and roll data from the built-in inclinometer.
Powering up
Connect the UMC-4 to a power source with one of the power cables listed
on pages 41 and 42. Power-up the unit by pressing the power button
momentarily.
Setting Time and Date
The time and date of the device are factory preset; however, they are set to
Central European Time, which might not be suitable for your location. To
set time and date, go to Menu>System>Date/Time>Set Date/Time.
Time and date are used in the naming of metadata files recorded to SD
card, as well as in the log file. The UMC-4 will keep time and date even if it
is disconnected from a power source, as it includes a built-in lithium battery
that normally lasts for more than five years.
Setting up Motors
Attach the motors for focus, iris and/or zoom to the lens. Make sure the
motors are properly mounted to their respective lens axes and will not
loosen up when operated.

Page 14 of 54 Universal Motor Controller UMC-4 – User Manual – V 02/2015
Connect the motor cables to their respective FOCUS, IRIS and ZOOM
connectors on the UMC-4.
Go to the Focus, Iris or Zoom sub-page of the Home screen and press
CAL. ALL to calibrate all motors.

Universal Motor Controller UMC-4 – User Manual – V 02/2015 Page 15 of 54
Set up the motor mounting side and torque (if applicable) in the Focus, Iris
and Zoom sub-page of the Home screen.
Side refers to the side of the lens the motor is mounted to (on standard
support rods underneath the lens).
Torque refers to the motor torque; a higher value means higher torque.
Connecting to Hand Unit
Set the radio channel on the UMC-4 in the Radio sub-page of the Home
screen. Make sure that the radio power is switched on and that the
selected radio channel is not already in use by another motor controller.
Set the hand unit to the same radio channel (see the hand unit’s user
manual for further instructions). Once connected, the UMC-4 status LED
will turn blue and the number of connected hand units will display on the
UMC-4 Home screen.
Selecting a Lens File
Select a lens table if you want to display lens data on the WCU-4 hand unit,
or use lens mapping to pre-marked focus rings and focus tracking with the
WCU-4 hand unit, or record lens data to SD card:
Go to the Lens sub-page of the Home screen.
Go to Add to Favorites and select the lens you want to use from the list.
Press ADD+USE to use the lens table and add it to your list of favorites.
You are now ready to shoot.

Page 16 of 54 Universal Motor Controller UMC-4 – User Manual – V 02/2015
Note: After connecting a lens motor to the UMC-4 and the lens, it must be
calibrated. The lens motor must be recalibrated under the following
conditions:
•When the lens motor is detached from the lens
•After changing lenses
•After a change in motor position while powered down
Omitting motor calibration might lead to damage of the lens due
to the high level of motor torque!
Note: You can program a custom lens file through the ALEXA web
interface or with the Wireless Compact Unit WCU-4 (SUP 2.0 onwards)
