3. General Description

The ARRI Ultrasonic Distance Measure (UDM) provides
a continuous reflection-based distance measurement
and automatic focus tracking, using the built-in Lens
Data System of the ALEXA Plus, ARRICAM, ARRIFLEX
435 Advanced/Xtreme and ARRIFLEX 416plus cameras
or the UMC-3 lens motor controller.

Main features

• Measurement range from approx.
0,4 - 10m / 1ft 4in - 33ft

• Selectable Meter / Feet display

• Automatic focus tracking with ARRI Lens
Data System equipment

• Pre-set measuring limits for exact object
tracking

• Fine-trimming for best performance
in different environments

• Large transflective LCD display for good
readability under all light conditions

The UDM consist of two units, the Display Unit and the
Sensor Unit. 3/8“ UNC bushings allow the units to be
mounted on standard supports in convenient positions.
The UDM comes with an 1,5m (5ft) interface cable.
Connection cables for interfacing to cameras and
UMC-3 must be ordered seperately (page 9).
A large control wheel on the Display Unit allows easy
setting of the UDM parameters, supported by a set of
status LEDs.
The small toggle switch under the large LCD display
changes the unit of measurement between meters and feet.

4. Setup

4.1. Standard Setup -

Fasten the UDM units in convenient places on or around the
camera using the 3/8” support on both units. Connect the
Display to the Sensor Unit using the blue labeled cable.
Choose the applicable supply cable either for ALEXA ,
ARRICAM,
camera or the optionally available UMC-3 cable. You may
create custom supply cables at your own risk.
Refer to chapter 6 for detailed information.

ARRIFLEX 435 / 435Advanced / 435Xtreme / 416 / 235

4.2. LCS Setup -

Using suitable cameras and accessories, the UDM provides
the operator with actual Depth-of-Field information on the
LDD-FP and controls automatic focus tracking when
required.
The UDM sends the distance information repeatedly in a
serial data stream to the connected unit. Applicable units
are ARRI cameras providing a LDD connector and built-in
lens motor drives, like the ALEXA Plus, the ARRICAM-ST/LT
equipped with a Lens Data Box and an unit incorporating
a LDD-FP connector, an ARRIFLEX 435 Advanced/Xtreme
with FEM-2 or an ARRIFLEX 416 plus.
Alternatively a UMC-3 will also interface the UDM data to
an LDD-FP in non-ARRI set-ups (e.g. video camera usage). As
the LDD-FP provides the complete UDM information, the Display
Unit may be disconnected after parameters have been

5. Operation of the UDM

5.1 Switching on

The UDM has no dedicated power-switch.
Power-on the UDM by using the power switch of the
connected supply source (Camera/UMC-3) or connect
the appropriate UDM cable to the supply unit.

5.2 Controls and Status LEDs

The blue Control Wheel is used for configuration setup.
Push to select and turn to change values.

The Toggle Switch changes the unit of measurement
between Metres and centimetres and Feet and inches.

SENSE LED: steady green shows successful measurement
FILM PLANE LED: yellow blinking indicates film plane

offset adjustment mode
SENSTIVITY LED: yellow blinking indicates sensitivity
adjustment mode
LIMIT LEDs: yellow blinking indicates value setting mode,
steady light indicates limits set to other than maximum
(default) value.
LDS-DOF LED: steady light indicates the object as being
within the calculated Depth-of-Field range, blinking
indicates the object to being outside of the Depth-of-Field
range. No light indicates, that no camera Depth-of-Field
signal is available.

Operation

5.3 Operation Settings

During operation the following changes or adjustments
are available:

Selection of the unit of distance measurement

Operation

Use the toggle switch to select either m/cm or ft/in

Setting of sensitivity
Press the control wheel briefly - the SENSITIVITY LED starts
blinking, indicating the device is in sensitivity mode. Turn
the control wheel and set the new sensitivity value. The
value range starts at 0 (OFF) and ends at 100 (MAX).
Adjust so that you achieve a steady green SENSE light in
the desired measurement range. Press the control wheel
briefly again to return to normal operation.

Setting of Film Plane offset

When the Sensor Unit is not mounted on the film plane,
the Film Plane offset will need to be recalibrated.
Measure the distance between the film plane and the
object. Press and hold the Control Wheel for about

1.5sec, until the FILM-PLANE LED starts blinking.
Turn the Control Wheel until the correct distance is
displayed. Press the Control Wheel briefly again to return
to normal operation.

5.5 Depth-of-Field and Focus Tracking

Using the settings and accessories described in chapter

4.2, the UDM uses the LDD-FP or the WRC-2 with LDD-FP
software option as a display for the actual Depth-of-Field.
As the LDD-FP provides the complete UDM information,
the UDM Display Unit may be disconnected after
parameters have been set.

Indicators on the LDD-FP show the following:
An active UDM (or CTM), the measured distance and
actual Depth-of-Field. Depth-of-Field is shown graphically
as a bar graph and is also displayed as numeric value.

In a cabled configuration the Focus Tracking function can
be activated by pressing and holding the blue tracking
button on the left side of the WHA-3.

Using the wireless setup, press and hold the BRIGHT - UP
button on the LDD-FP.
As long the button is kept pressed, the focus motor will
follow the measured distance.
