Chapter 3 – czoom II Set up 07-07 9/ 35
3CZOOM II SET UP
The czoom II (see Fig. 3. 1) provides all operational
functions necessary to control a zoom motor. It
comes with an integrated display which shows the
current motor position as well as other relevant
information.
The czoom II can be used in two different ways:
oAs stand-alone device with a connected zoom
motor.
oWith the c amin or camin mono (via a wireless
module or CBUS cable connection).
3.1 The czoom II in stand-alone operation
In stand-alone operation, the czoom II has a zoom
motor attached. In this mode of operation the c zoom
II is usually attached to the pan bar.
The czoom II c an be mounted to the pan bar in the
following ways:
oWith the cfast-c zoom, which is screwed on via the
rosette disc.
oDirectly screwed to a pan bar joint, e.g. by
Oppenheimer
.
3.1.1 Attaching the czoom II v ia cfast-czoom
For practical zoom control, the czoom II can be
attached to the pan bar with the cfast-czoom (see Fig.
3. 2). The cfast-czoom is composed of an arm, two
rosettes and a cfastener. It can be attached to any
rod 15-28 mm, e.g. the pan bar. Via cfast-czoom it is
also possible to adjust the angle between czoom II
and pan bar and thus achieve optimum user comfort.
Note The arm of the cfast-czoom has two rosettes.
One rosette is attached to the cfastener, the other is
attached to the czoom II. The rosette attached to the
cfastener can be switched from one side of the arm to
the other, so that the cfastener can be attached to
the inside or outside of the czoom II.. (see Fig. 3. 3)
Fig. 3. 1
Fig. 3. 2
Chapter 3 – czoom II Set up 07-07 10/ 35
1. Attach the czoom II to the cfast-czoom using the
rosettes. Secure tightly with the tightening lever.
2. Attach the cfastener to the pan bar (or any other rod
15-28 mm). Secure tightly with the tightening lever.
Note The angle between czoom II and pan bar can
be adjusted very easily. Loose the tensioning screw,
so that the rosettes can be rotated in opposite
directions, than adjust as desired.
3.1.2 Attaching the czoom II to the pan ba r joint
The czoom II can be directly mounted to a pan bar
joint (articulation), e.g. by Oppenheimer.
In this c ase, the Oppenheimer Articulation is attached
to the pan bar. The joint is directly screwed to the
pan bar adapter of the czoom II. ( ee Fig. 3. 4)
Note It is possible that the pan bar adapter of the
czoom II is screwed off.
3.1.3 Operating the czoom II
When operated in stand-alone mode, the czoom II is
usually powered by a camera yet it can also be
powered independently by an inserted battery.
Note The operating time of the battery inserted into
the czoom II will strongly depend on the frequency of
motor activity it usually covers 2-4 hours.
1. Use the ca mera cable to connect the czoom II with
the camera.
Note In the attac hment (Appendix A.2) of this user
guide you find a list of supported cameras and the
cables require d for their use.
2. Connect lens motors to the czoom II. The following
motors can be connected to the czoom II:
oARRI CLM-1 connect with RLM-2 (FI 7 p, FI 5p)
cable to CBUS connector (blue).
Fig. 3. 3
Fig. 3. 4

Chapter 3 – czoom II Set up 07-07 11/ 35
Note With the RLM-2 cable, cable lengths ove r 50
metres are possible.
oARRI CLM-2 connect directly with the
integrations cable (FI 12p) to the zoom motor
connectors (green).
oDenz connect directly with the integrations cable
(FI 12p) to the zoom motor connectors (green).
oHedén M26VE connect with the RHM-x (FI 12p,
LE 7p) cable to the zoom motor connectors
(green).
Note You can connect a 10m cable with Hedén
M26VE (c able RHM-4).
Note When using the Hedén motors (see Fig. 3.
5), the gear rings can be easily exchanged
acc ording to teeth size (see Fig. 3. 6). They can
also be placed on either side of the motor.
i. Push on the small rod exiting the opposite
side of the gear ring mount.
ii. Choose the gear ring with your desired teeth
size.
iii. Choose the side on which you would like the
gear ring to be placed.
iv. Place gear ring rod into the hole located on
the gear ring mount.
v. Gently push gear ring while slowly turning it,
until the rod pops into the hole.
vi. Push rod completely into the hole until it
clicks.
The height of the rod attachment ring can also be
adjusted this helps to assure that the motor
actually reaches the lens gear ring.
oPreston connect with RPM -1 (FI 12p, LE 7p)
cable to the zoom motor connectors (green).
oScorpio connect with RSM-1 (FI 12p, LE 7p)
cable to the zoom motor connectors (green).
Warning Make sure that cables do not get in the
way of equipment during operation or camera
handling (movement).

Fig. 3. 6
Chapter 3 – czoom II Set up 07-07 12/ 35
oENG lenses ENG lenses can be directly
connected to the c zoom II via a 16p EXT plug. In
this case, the czoom II cannot be powered by the
ENG lens interface. For a list of available cables,
see the attachment (Appendix A.2).
3. Switch c zoom II ON [Z12].
The czoom II comes with a two-level ON switc h.
oSwitch setting ON I: In this setting, the connected
motor is powered by supply voltage.
oSwitch setting ON II: In this setting, the czoom II
operates in boost mode. Voltage supply for any
connected motor is provided by a boost module.
The motor runs with higher speed. As long as the
zoom control joystick is operated steadily, the
motor will continue to move at a constant speed –
independent of actual supply voltage.
Note De pending on the supply voltage, the czoom II
in boost mode (ON = II) has a higher power
requirement. Not all cameras are capable of providing
the required power supply. For these cameras, a
separate supply for the czoom II is necessary (e.g. a
battery).
Typical values with a motor are as follows:
supply voltage ON=I ON = II
24V 0.5A 0.6A
12V 0.5A 1.1A

3.2 The czoom II used with the camin
The c zoom II can be used together with the camin or
camin mono in wireless m ode, in w hich case it will
control the camin zoom motor.
Note The czoom II can only be used in wireless
mode if it has been delivered with the option czoom
II-ext. In this case, the czoom II has a „wireless
extension“ label attached.
Note For radio operation no external a ntenna is
necessary. The czoom II comes with an internal
antenna.
The czoom II can also be operated in hard-wired
mode. Connect the czoom II and the camin with the
CBUS cable (FI 7p, FI 7p). As soon as the CBUS cable
is connected, the system’s wireless mode will turn off
automatically. In hard-wired mode the c zoom II does
not have to have a battery inserted, since it is
powered by the CBUS cable (see Fig. 3. 7).
Note Make sure to follow the setup guidelines for the
camin or camin mono. For further information see the
user guide “Lens & Camera Control System”.
3.2.1 Attaching the czoom II
In this operational mode the czoom II can also be
attached to the pan bar or another bar, yet in most
cases will be held by the user.
3.2.2 Operating the czoom II
1. Insert a battery. Press until it snaps in with an audible
click.
Note If you use the czoom II hard-wired mode no
battery is necessary.

Chapter 4 – System Operation 07-07 16/ 35
4SYSTEM OPERATION
For working with the system, the czoom II has to be
assembled as described in chapter 3 „czoom II
Setup“.
4.1 Motor calibration
Irrespec tive of the zoom motor being directly
connected to the czoom II or the camin, motor must
be c alibrated each time a lens is attached, each time
a motor is attached and in case the lens motor has
been moved/adjusted ma nually.
The blinking message CAL REQ on the display
indicates that motor calibration is required.
Simultaneous calibration of all connected
motors
Normally, the czoom II controls only the zoom motor
(stand-alone operation)
If there are several motors in the system (e.g. a focus
motor and a zoom motor are both connected to the
camin), all motors are usually calibrated
simultanously.
1. Push the yellow CAL button [Z15] located at the side
of the czoom II for one second.
Single motor calibration
If there are several motors in the system (e.g. a focus
motor is also connected to the camin), it is possible to
calibrate the motors individually.

Chapter 4 – System Operation 07-07 17/ 35
1. Push and hold the CAL button [Z15].
2. While holding the CAL button, push the LENS button
[Z18] of the czoom II to calibrate the zoom motor
only.
On the display, a calibration process is indicated by
the status information CAL in the position window.
Note If the camera is running, the motor cannot be
calibrated.
4.2 Zooming
With the blue zoom control joystick [Z10] the zoom
motor can be controlled directly at the lens. To move
the zoom motor, put pressure on the zoom control
joystick to move it into the direction you wish to
move the motor. The more pressure you put on the
joystick the faster the motor will move. (see Fig. 4. 1)
Note The zoom control joystick is sensitive to
pressure. The motor speed depends on the a mount of
pressure you are putting on the joystick, yet the
button does not physically move.
4.3 Setting the zoom speed
The speed of the zoom motor can be preselected via
zoom speed. If you press the UP [Z2] and DOWN [Z3]
buttons (see Fig. 4. 2), the speed is gradually
adjusted from 0 to 99. The longer the buttons are
pressed, the faster the adjustment is carried out.
The zoom speed presets the maximum s peed of the
zoom motor in case that maximu m pressure is put on
the zoom control button. If the zoom speed is set to
1, maximum pressure on the zoom control joystick
will yield a slower motor speed then if the zoom speed
were set to 99 and maximum pressure is put on the
zoom c ontrol button.
If "speed = 0" is selected, the motor does not move,
even if you press the ZAP button
Fig. 4. 1
Fig. 4. 2
Chapter 4 – System Operation 07-07 18/ 35
Note The motor speed depends on both the motor
itself and the power supply. The czoom II can be
switched on in two settings. In setting ON II the
motor voltage is boosted. The motor can move faster
in setting ON II. If the zoom motor is attached to the
camin, you c an also boost the voltage there.
4.4 ZAP – Zoom as Fast as Possible
Irrespec tive of the value the motor speed has been
set to with zoom speed, the motor can still be moved
with the fastest possible speed by pressing the ZAP
button (Zoom as Fast as Possible) [Z17].
The ZAP button is located at the rear side of the
czoom II. (see Fig. 4. 3)
1. With your index finger, hold down the ZAP button
loc ated at the rear side of the czoom unit. On the
display, “SPEED” changes to “ZAP”.
2. By using your thumb, put maximum pressure on the
zoom control joystick in the direction you wish the
motor to move.
3. While still holding the ZAP button, move to the desired
zoom position.
4.5 Set motor direction
The motor direction of the zoom motor can be
changed via the DIR switch situated on the side of the
czoom II. (see Fig. 4. 3)
1. Slide the DIR switch to change the motor direction.
You c an change the motor direction again by simply
sliding the switch back.
Note If a CLM-1 motor is connected, the motor
direction can only be changed on the CLM-1 motor
itself.
Note If the c zoom II works w ith the camin, and the
zoom motor is attached to the camin, the motor
direction can be changed on both the czoom II and
the camin.

4.6 Setting motor limits
Motor limits are set to control a limited range of the
scale only. Set limits remain as programmed until
they are erased by the user. They also remain as
programmed when the c zoom II is turned off.
Limits are set as follows:
1. By using the zoom control joystick, move the motor
to one of the two desired limits, and stop.
2. Push AND hold down the zoom LENS button [Z18]
(see Fig. 4. 5).
The position indicator on the display shows that the
limits are being set.
3. While still holding down the LENS Button, move the
motor to the other desired limit, and stop.
4. Release the LENS Button.
From now on the motor will move exclusively within
these set limits.
The position bar on the display shows the set limits.
To erase limits
1. Press the LENS Button.
4.7 Camera run
The camera is started via the green RUN button
situated above the zoom control button.
1. To start/stop the camera, push the RUN button [Z8].
On the RUN LED [Z9], the camera status is displayed
as follows:

please refer to Appendix A of this user guide.
Note If the camin is in the radio circuit, came ra run
is initiated via camin only. In this case, the cable
connecting w ith the camera has to be attached to the
camin.
RUN toggle mode
If a camera does not provide an output for camera
run (video ca meras) or this feedback channel in the
cable is not used, the came ra status will not be
displayed. In this case, to still have some control
whether the camera is running or in standby mode,
the czoom II can be started in RUN toggle mode.
1. The czoom II is turned off.
2. Press and hold the RUN button during powe r up
(switc h is moving from OFF to ON =I or II).
The czoom II is now in RUN toggle mode.
3. To start/stop the camera, push the RUN button.
Each time you press the RUN button, the RUN LED
switches between ON and OFF, irrespective of the
camera being in standby mode or running.

czoom II is turned off.

Chapter 4 – System Operation 07-07 21/ 35
4.8 MEMORY und RECALL
By pressing the ZAP [Z16] and LENS [Z17] button
simultaneously, the current motor position can be
stored. (see Fig. 4. 6)
This function is called MEMORY. A stored motor
position is indicated by a marker on the position bar
of the display. By pressing the RECALL button [Z7], a
motor can be automatically moved to any previously
stored motor position.
Note A stored position will be lost as soon the c zoom
II is turned off. Motor calibration will also delete a
stored position.
Note When using the Arri CLM-1 motor, no pos itions
can be stored.
By pressing the RECALL button, the motor is moved
to the stored motor position, i.e. the motor goes from
the current position A to the stored position B. The
speed used to move the motor from position A to
position B is set via the RECALL SPEED menu.
While the RECALL function is performed, the zoom
control button is loc ked. As long as the motor is
mov ing, no further position parameters can be set.
The RECALL function can also be performed with
limits set. If a motor position is stored before a limit
is set, the motor position can be situated beyond the
limit range. When pressing the RECALL button, the
motor will also move to the position beyond the limit
range.
Yet in this case, pressing the zoom control will move
the motor into the set limit range only a movement
away from the set limits is not possible.
According to the setting defined in the RECALL menu,
the RECALL button can be used in three different
ways:
oGOTO
oHOLD
oTOGGLE
For how to set functions, see c hapter 5 THE DISPLAY
AND ITS FUNCTIONS
Note By default, the czoom II is set to the function
GOTO.
Fig. 4. 6
Chapter 4 – System Operation 07-07 22/ 35
4.8.1 Function GOTO
The function GOTO moves the motor from current
position A to stored position B. The motor stops and
remains in position B. This is initiated by pressing the
RECALL button shortly.
After having reached the stored position B, the zoom
motor can be manually directed to another position.
Press the RECALL button again to go back to the
stored position.
If the czoom II is in the function mode RECALL GOTO,
a motor position is stored as follows:
1. The desired position is targeted via the zoom control
joystick.
2. By pressing the ZAP and LENS button simultaneously,
the value is stored.
The position indicator on the display shows a marker
for the stored value.
Note If you store another current motor position, the
previously stored value will be overwritten.
4.8.2 Function HOLD
In function mode HOLD the motor moves from current
position A to stored position B as long as the RECALL
button is pressed. If the RECALL button is released,
the motor moves back to its initial position A.
In function mode HOLD the motor positions are stored
as was described for function mode GOTO.
4.8.3 Function TOGGLE
In function mode TOGGLE, a short pressing of the
RECALL button will move the motor between two
stored values B and C. To use this function mode, two
values have to be replaced by MEMORY:

Chapter 4 – System Operation 07-07 23/ 35
1. With the help of the zoom control stick, move to the
first motor position.
2. Store this value by simultaneously pressing the ZAP
button and the LENS button.
The position indicator on the display shows a marker
for the stored value.
3. With the help of the zoom control joystick, target the
second position.
4. If you press the ZAP button and the LENS button
simultaneously, the second value is stored.
5. The position indic ator on the display shows a marker
for the stored value.
On the display, the motor position moved to from the
current position is shown as a closed memory marker.
The second marker is displayed as a concave marker.
Moving to a stored position will thus change the
graphic representation of markers.
Note If you subsequently store another current
motor position, the second stored value (the concave
marker) will be overwritten.
4.9 Replacing the marker strip
The czoom II comes with a replac eable marker strip.
A magnet fixes the strip to the casing it c an be
removed by a slight pulling movement. (see Fig. 4. 7)

irrespective of the czoom II being used in stand-alone
mode or with the camin.
For the torque, the following settings are available:
oLIGHT – the motor turns w ith minimum torque
oWEAK
oMIDDLE
oSTRONG – the motor turns with maximum torque
Note If the torque is too light, there is a risk of the
motor not reaching the lens limit. It is therefore
recommended to c heck during calibration whether the
motor torque is sufficiently strong.
Note The Arri CLM-1 motor torque as well as the
torque of ENG Lenses cannot be adjusted.
Note The default setting of the motor torque is
MIDDLE .
Press the MENU button to go back to the main menu.
5.1.2 RECALL menu item
