Introduction 11
4 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 frameaccurate 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. All packed in a durable, splash-proved
housing
NOTICE
To tap the full potential of the device, have all connected units
updated to the latest available firmware.

Quick start guide 13
5 Quick start guide
This quick start guide walks you through the required steps, to set
up the UMC-4 with three motors and a wireless hand unit.
Mounting on camera
Mount the UMC-4 on the camera, by using the L-Bracket, with
the antenna pointing upwards and the motor connectors pointing
towards the lens. This orientation is necessary for the generation
of valid tilt and roll data recorded as metadata (See "Metadata",
page 40)
Powering up
Connect the UMC-4 to a power source with a designated power
cable (See "Part Numbers", page 42) and power the unit up,
by pressing the power button.
Setting Time and Date
The time and date of the device are factory preset for Central
European Time. To set time and date, go to Menu>System>Date/
Time>Set Date/Time. Time/date are obligatory for proper
metadata and log file recording. The UMC-4 will keep time and
date even if it is disconnected from a power source because of an
built-in buffer battery.
Setting up Motors
Properly mount the motors to the lens. Take care for a
mechanically rigid setup. Connect the motors to the related axís
connectors, if cforce motors are used, select the corresponding
axis on the motor. Go to one of the axis motor menu and press
CAL. ALL to calibrate all motors. Set up the motor mounting side
and torque in the dedicated motor menu. Side refers to the side of
the lens the motor is mounted to (rods underneath the lens).
Torque refers to the motor torque (1=low to 4=high).

14 Quick start guide
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. Set the
hand unit to the same radio channel. A successful connection is
indicated by the number of connected hand units on the UMC-4
Home screen.
Selecting a Lens File
For the features listed in chapter "Lens", page 21 this step is
obligatory, otherwise this step could be skipped. 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.
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
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)
