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#'
<_hij][d[hWj_edkd_jm_j^i[YedZ][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.
