Working on a film set is a hectic business, and the equipment must meet high standards
so you can perform your job as efficiently as possible. In designing this new generation
of components for the Wireless Remote System we have carefully looked at the needs of
the assistants and talked to many of you about existing lens and camera remote systems.
In addition we have talked to many rental houses about their needs. As a result these new
components are substantially smaller and lighter than before, while at the same time having
longer battery life and a more robust radio transmission.
No shoot is like the other, and a fast Steadicam chase requires a different wireless setup
than a camera on a crane for a music video with speed ramps. To make sure that you can
quickly assemble a wireless system for any type of shoot, the new system is modular to the
core. It is as easy to assemble a minimal configuration that controls just focus and camera
as it is to add wireless control for complex ramps or the Lens Data Display for an accurate
display of lens rings and camera status. This system has the flexibility to provide just the
right tool for the job, while offering an unrivaled list of features.
Our new Wireless Remote System can control almost all camera and lens functions for
ARRI cameras, including tight integration with ARRICAMs and the 435 Xtreme, and all
lens functions for many other cameras. We have simplified some procedures, like setting
limits, and made sure the old components still fit the new gear.
It has been fun to develop this system, and we hope that it helps you on your next job.

A lens and camera control system as modular and flexible as the ARRI Wireless Remote System necessar-
ily consists of many individual parts. This guide is designed so you can easily navigate those parts and get an
overview of what is available and how the system can be configured. For clarities sake, we have divided the
individual parts of the system into the following categories. Please note that many of the smaller accessories
are not listed separately on this page. A full listing can be found in the Compatibility Table at the end of this
guide.
>WdZHWZ_ei
These are held in the hand of the assistant and are responsible for creating the radio link to the camera radio.
The technical name for the hand radios is “Wireless Main Units”. The Wireless Remote System includes the
Wireless Main Units WMU-1, WMU-2 and WMU-3.
>WdZ]h_f7jjWY^c[dji
Handgrip attachments can be used instead of hand radios when a cable connection is preferred. The Wireless
Remote System includes the Wired Handgrip Attachments WHA-1, WHA-2 and WHA-3.
>WdZ9edjhebb[hi
These attach to the hand radios or handgrip attachments, and control or display aspects of the lens and camera.
They may control focus, zoom or iris, they may control speed ramps or display lens information. Hand
controllers for lens control include the Wireless Focus Units WFU-1 and WFU-2, plus the Wireless Zoom
Units WZU-1 and WZU-3. You can also control the zoom with the ZMU-3. The Wireless Remote Control
WRC-1 is a hand controller for complete camera remote control, and the Lens Data Display for Focus Puller
LDD-FP can accurately display lens and camera status.
9Wc[hWHWZ_ei
Camera radios are attached to the camera and communicate with the hand radios. Camera radios include the
Universal Radio Module URM-1, URM-2 and URM-3. Camera radios are also part of the Lens Data Boxes
LDB and LDB-2 for ARRICAM Studio and Lite.
Cejeh9edjhebb[hi
Motor controllers contain the electronics to drive the lens motors. In the case of the ARRICAM Lens Data
Boxes, both motor controller and camera radio are combined into one unit. Motor controllers include the
Universal Motor Controller UMC-1 and UMC-3, the Functional Expansion Module FEM-2, plus the Lens
Data Boxes LDB and LDB-2 for ARRICAM Studio and Lite.
B[diCejehi
Lens Motors connect to the motor controllers, and physically move the lens rings. The Wireless Remote
System includes the Controlled Lens Motors CLM-1 and CLM-2.

The radio modem provided with the WMU-3, Arricam Studio LDB-2, Arricam Lite LDB-2,
UMC-3 and URM-3 offers several advantages over previous units, including smaller size,
less power comsumption and improved transmission. Due to these improvements, it cannot
cross-communicate with the previous radio modems originally used in the WMU-1, original
Arricam Studio LDB, original Arricam Lite LDB or Radio Modem URM-1.
However, all of these units can be upgraded via installation of the new radio modem.
In order to maintain discrete designations for all WRS units, a naming convention was ad-
opted as follows:
<_hij][d[hWj_edkd_jm_j^\_hij][d[hWj_edhWZ_eceZ[c0 NNN#'

I[YedZ][d[hWj_edkd_jm_j^i[YedZ][d[hWj_edhWZ_eceZ[c0 NNN#)"
where „XXX“ denotes the actual unit referred to: for example, „WMU-3“ would be the
Wireless Main Unit, second generation with second generation radio modem.
To denote presence of the second generation radio modem, a colored washer has been added
to the antenna port. The color of this washer was originally blue. However, with advances in
video transmitter technology, a software change was necessary to minimize interference. To
denote the software change, a green washer replaces the blue washer. It is important to note
that units with green washers cannot communicate with units with blue washers.

There are two ways to connect the hand controllers with cables to the cameras: First, the
Wired Handgrip Attachments WHA-2 or WHA-3 connect with cables to the cameras, and
the hand controllers can be attached to them. Use cables LC-M1, LC-Z1 or LC-Z2 to con-
nect to the LCS port of a 435 Xtreme, ARRICAM, 416 Plus, or UMC-3; use cable KC-70
to connect to the CAC port of an ARRICAM. The Wired Handgrip Attachment WHA-1
connects the Wireless Remote Control WRC-1 with cable WC-W1 to the CCU port of the
ARRIFLEX 435, 535 and 16 SR 3 or to the remote port of the ARRIFLEX 235.
Second, it is possible to connect a cable between the antenna connector of the hand radios
and the camera radios. Cable WC-A3 can be used to connect the WMU-1 antenna connector
to the antenna connector of URM-1, Studio LDB or Lite LDB. The same cable is also used
to connect the WMU-2 or WMU-3 to the antenna connector of URM-2, URM-3, Studio
LDB-2 or Lite LDB-2. You can also use the WC-A3 cable to connect the WMU-3 to the
UMC-3. Don’t use cable WC-A1. Authorized ARRI Service Centers can upgrade cable
WC-A1 to WC-A3.
Please note that with or without cable, compatibility between units is dictated by radio
modem compatibility as described in „New Radio Modem“ above.
Cable WC-A2 can be used for extending the antenna away from a radio unit.

Most parts of the wired Lens Control System can still be used with some minor limitations.
Below is a short run down of compatibilities. Details can be found in the Lens Control
System manual.
The Zoom Main Unit (ZMU-1 or ZMU-2) can be connected with a cable to the UMC-1,
Studio LDB, Studio LDB-2, Lite LDB, Lite LDB-2 or FEM-2 to control zoom. It is also
possible to connect the Zoom Main Unit directly to the CLM-1 motors, which in turn
must be connected to a UMC-1, LDB, LDB-2, FEM-2 or external power supply.
For wireless use, the ZMU-3 becomes now part of the ARRI Wireless Remote System.
Via the Wireless Zoom Bracket WZB-3 it attaches to the Wireless Main Unit WMU-3. It isIt is
also possible to use the ZMU-3 in wired mode, connected with a cable to the the UMC-3,
Studio & Lite LDB-2, FEM-2 or the UMC-1 in combination with URM-2 or URM-3.
Having multiple zoom controllers connected (like a ZMU and a WZU, for instance) is not
a problem, even though one of them will be the master and the other one will not function.
One or two Focus Iris Units (FIU-1) can be connected to a ZMU-1 or ZMU-2. From
ARRICAM Software packet 03E on this configuration will also work with the ARRICAM
system. When using the FIU-1 with the ARRICAM system, it is recommended to
not use a Wireless Main Unit or WHA-2 at the same time.

The Wireless Main Unit is the heart of the ARRI Wireless Remote System. It accepts the
hand controllers for focus and iris (WFU-1, WFU-3), zoom (WZU-1, WZU-3), camera
remote control (WRC-1), the Lens Data Display for Focus Puller (LDD-FP) and it com-
municates with the camera. Up to three Wireless Main Units can talk to one camera at the
same time.
The WMU-3 is small in size and lightweight, making it easy to hold for long periods of
time. In addition, the new radio modem has a more robust transmission and less power
consumption than its predecessor. An ergonomic hand strap assures that the whole unit
stays safely in the assistant’s hand. With the new software version (green washer) the
transmission is reenhanced.
Unique to the WMU-3 are the abilities to accept the Lens Data Display for Focus Puller
(LDD-FP) and to accept two control units at once using the Wireless Expansion Bracket
(WEB-3). It is possible, for instance, to use the Lens Data Display for Focus Puller (LDD-
FP) together with a Wireless Focus Unit (WFU-1 or WFU-3). Another possible combina-
tion is the Wireless Remote Control (WRC-1) with a Wireless Focus Unit (WFU-1 or
WFU-3). By employing two Wireless Main Units WMU-3, it is possible to have focus,
zoom, iris, camera remote control and the LDDFP all at the same time.
Compatibility: The WMU-3 communicates with UMC-3, URM-2, URM-3, Studio LDB-2
and Lite LDB-2. As power supply the Wireless Battery Unit WBU-3 has to be used;
WBU-1 and WBU-2 cannot be used. The WRC-1 needs to run at least software version
1.08. When using the WMU-3 with the Wireless Remote Control (WRC-1) or the Lens
Data Display for Focus Puller (LDD-FP), neither WZU-1 nor WZU-3 should be attached
between the units. LDD-FP and WRC-1 cannot be used on one WMU-3 at the same time.
Neither can two WRC-1 or two LDD-FP units.

The WFU-3 is used to control focus and/or iris. Focus and iris can be assigned freely to
hand wheel and slider, and electronic lens and knob limits can be easily set. In addition
it is possible to set mechanical knob limits.
The WFU-3 is similar to the WFU-1 except that it is lighter than the WFU-1 and the
index marker can be rotated 180° for better viewing. This movable index marker is
especially useful when the WFU-3 is mounted on the WMU-3, WHA-2 or WHA-3,
since the resulting remote control is so small that it can easily be swapped between the
left and the right hand and can be held at many different angles.
Compatibility: The WFU-3 can be attached to any Wireless Main Unit (WMU-1,
WMU-2 or WMU-3) for wireless operation with any camera or to the
Wired Handgrip Attachments WHA-2 or WHA-3 for wired operation with
ARRICAM, 416 Plus or 435 Xtreme.

The WZU-3 is used to control zoom. Zoom speed can be adjusted and zoom limits can
be easily set. The WZU-3 is similar to the WZU-1 except that it is lighter than the WZU-
1 and the position of zoom knob and the LENS limit controls are reversed. The reversed
zoom knob is in the perfect ergonomic position for the assistant’s thumb when the WZU-3
is used on WMU-3, WHA-2 or WHA-3.
Compatibility: For wireless operation, the WZU-3 was especially intended for use with
the WMU-3, although it can be used with other main units. For wired operation with
ARRICAM, 435 Xtreme or 416 Plus, WZU-3 can be used with Wired Handgrip Attach-
ments WHA-2 or WHA-3. The WZU-3 can be placed between the Wireless Focus Unit
and a Wireless Main Unit or Wired Handgrip Attachment, so focus, iris and zoom controls
are together on one small and lightweight controller. The WZU-3 should not be placed
between LDD-FP or WRC-1 and a Wireless Main Unit.

The Wireless Remote Control WRC-1 allows for remote operation of all current ARRI-
CAM and ARRIFLEX cameras. Its basic application includes the use as an extension of the
camera display in setups where the camera is difficult to access. More sophisticated features
are manual or programmed speed, shutter or iris ramps, speed change with exposure
compensation through shutter and/or iris, and shutter changes with exposure compensa-
tion through iris (or vice versa) for a shift in depth-of-field. The WRC-1 can be operated
wirelessly on the Wireless Main Units (WMU-1, WMU-2, WMU-3) or hardwired with the
Wired Handgrip Attachment (WHA-1, WHA-2, WHA-3).
Compatibility: For use on a Wireless Main Unit with the new radio modem WMU-2 or
WMU-3, the WRC-1 should always have the latest software version. Otherwise some
functions will not work. To work the WRC-1 together with the 235, SW-Version 1.22
is needed. It is not possible to operate the WRC-1 and the Lens Data Display for Focus
Puller (LDD-FP) on the same Wireless Main Unit. For wireless operation of WRC-1 and
LDD-FP at the same time, two Wireless Main Units must be used. The same is true for two
WRC-1 and LDD-FP units.

The LDD-FP is a small and lightweight display showing critical lens information and
camera status. It can be configured to show focus scale, zoom scale, iris scale and came-
ra status in any combination. Because of its small size it can be mounted in many ways,
allowing the assistant to see precise lens and camera information while keeping an eye on
the action. The screen of the LDD-FP is a high contrast Advanced TFT color screen with
adjustable brightness.
Compatibility: It is possible to use the LDD-FP together with the Cinematography Elec-
tronics Cine Tape Measure. The CTM calculates the distance between the filmgate and the
focus target. This distance is marked with a litle arrow in the focus scale of the LDD-FP,
as long as you hold a button on LDD-FP or WMA-3. The Lens Data Display for Focus
Puller (LDD-FP) can be operated wirelessly with the Wireless Main Unit 3 (WMU-3). To
use the LDD-FP on the WMU-3, compatible software is required for the LDD-FP, Studio
Lens Data Box LDB-2, Lite Lens Data Box LDB-2. UMC-3 and FEM-2. The LDD-FP is
not compatible with WMU-1, WMU-2, WHA-1, WHA-2 or WHA-3. It is not possible
to operate the WRC-1 and the Lens Data Display for Focus Puller (LDD-FP) on the same
Wireless Main Unit. For wireless operation of WRC-1 and LDD-FP at the same time, two
Wireless Main Units must be used. The same is true for two WRC-1 and LDD-FP units.
