3 Assembling the DRW-1
3.1
Mounting the DRW-1 base!
!
The bottom of the DRW-1 mounting base offers multiple mounting options:
3/8” threads for long camera dovetail plates,
like the O’Connor plate code 08283, !
Euro style quick release plate code 2575-120,
or the Sachtler sideload plate M code1164.
At the bottom there are three circular arranged
thread sets for Mitchell and Euro mounts.
Mitchell Mount K2.0010427, !
Euro Mount K2.0010426 and the !
O’Connor Mitchell Base code 08281
can be mounted to the bottom of the DRW-1 base.
NOTE
To ensure a tight fit, use a minimum of two 3/8” screws
when a dovetail plate is used and four screws
for the Euro Mount and the Mitchell Mount.
3.2!
Mounting the DRW-1 modules
!
There are three M3 threads positioned at the left,
at the bottom, and the right side of the DRW-1
module.
Place the DRW-1 module carefully into the
DRW-1 carrier and tighten all three screws!
using a 3mm hex key.
NOTE
Ensure that all three screws are tightened evenly,
otherwise the DRW-1 module will have a loose fit,
which may affect the application.
3.3 !
Mounting the hand wheel!
!
Turn the location pin of the drive shaft to a 12:00 o’clock position.
Turn the blue fluid drag ring (friction) to the right to reach full friction.
Locate the groove inside the mounting hole of the hand wheel and
bring it into the 12:00 o’clock position too.
Now place the wheel onto the conic drive shaft. !
When the hand wheel has reached its final position, !
tighten the blue locking screw.
NOTE
Turn the fluid drag ring (friction) fully back to the left to reach
the lowest possible friction level.

4 Connecting the LBUS cables!
4.1 Introduction
Every DRW-1 module is equipped with two LBUS connectors
and daisy chain technology. !
Up to three DRW-1 modules can be linked up in a row. !
Each DRW-1 module has two identical, bi-directional
LBUS interfaces providing power and control signals
to the DRW-1 module.
4.2 Connecting the DRW-1 modules
The DRW-1 Set comes with the following LBUS cables:
1 x Cable LBUS 0.3m/1ft K2.0006750
1 x Cable LBUS 0.5m/1.5ft K2.0006751
The illustration shows how to
daisy chain one wheel to the other
and then with the remote control panel.
The LBUS sockets are located at the
sides of the SRH remote control panel.
Risk of electric shock and fire!
Short-circuits may entail lethal damage!
Before use, read and follow all relevant instructions.
Use solely and exclusively as described in the instructions.
Never open. Never insert objects.
For operation, always use a power source as indicated in the instructions.
Always unplug the cable by gripping the plug, not the cable.
Never try to repair. All repair work should be done by a qualified !
ARRI Service Center.
Never remove or deactivate any safety equipment !
(incl. warning stickers or paint marked screws).
Always protect from moisture, cold, heat, dirt, vibration, shock, or aggressive
substances.
!DANGER
Risk of fire!
Risk of short-circuits and back currents to power supplies/batteries:
Always use original ARRI/cmotion LBUS cables to external power sources !
(D-Tap, XLR)! ARRI/cmotion LBUS cables to external power sources provide !
a protection circuit to prevent back currents to power supplies/batteries.
!DANGER

5 Selecting the axes
Each DRW-1 module has a selection button for !
Pan, Tilt and Roll, at the top.
Initially Roll of P T R will be selected and visible, !
after the SRH remote panel had been connected !
to the LBUS.
By pressing the button Pan, Tilt and Roll, the desired
axis for each wheel can be selected.
CAUTION
Ensure that each wheel is assigned to only one individual axis. !
Avoid assigning two wheels to the same axis.
CAUTION
A blue blinking LED indicates a problem in the LBUS daisy chain.
6 The brake
!
The DRW-1 wheels are equipped with a brake
lever, which goes back to the ARRI Gear Head.
The brake lever allows the operator to engage or !
disengage the wheel from the selected motor axis.
NOTE
An unlocked wheel will be indicated by a green LED,
A locked wheel will be indicated by a red LED.
NOTE
Disengaging the wheels can also support operation.
When you need to reproduce a movement and you want the position of the crank
to be at a certain angle, for example at the end of the movement, than first move the
head to the desired end position, disengage the wheel and bring the crank to the
required angle.
Now engage the wheel again and move the head backwards to the starting point.
Start the movement from the beginning.
7 Fluid Drag Ring (friction)
!
The DRW-1 wheels are equipped with a fluid drag ring, !
which allows friction to be adjusted.
!
This unique feature allows the operator to manage the
accuracy of the head through a mechanical friction
adjustment, instead of a software value like
Ramp or Damp.
The mechanical friction allows the setting of Ramp values !
in the remote SRH-3 remote control to zero, or close to zero. !
This will ensure that the DRW-1 wheels and the remote head
reacting prompt and precise.!

Speed
In the factory preset setup, the Speed is !
assigned to the knobs K1, K2 and K3.
Changing the speed value will also change the
turns required to do a 180° Pan.
!
NOTE
In Speed Mode you will do a 180° turn:
• with two full turns of the wheel, when the speed is set to 100%
• with three full turns of the wheel, when the speed is set to approximately 68%
• with four full turns of the wheel, when the speed is set to approximately 48%
By adding a positive Ratio value, you will gear up the wheel more and more
Depending on the camera payload, one 360° turn of the wheel can cause a 180°, !
or even a 360° turn of the head.
NOTE
Ratio will not make the head move faster, but a high positive value will allow you to reach
the maximum speed more quickly.
NOTE
A negative Ratio value will divide the maximum speed. If the ratio value is set to the lower
negative value the head will only reach 1/5 of the possible maximum speed.!
