WELCOME TO THE AFX
How the AFX’s AUTOFOCUS functionality works
In order to generate the distance to the focus target that is required to move the lens focus
to the correct position, the AFX incorporates a LIDAR sensor.
The LIDAR sensor calculates distance by transmitting an eye safe beam towards a target
and then measuring the time it takes to return when it is reflected back. This process,
known as Time Of Flight, produces an accurate measurement with an effective range of
between 2 cm and 12 metres and has the advantage of being able to be used in low and
even no light situations.
The AFX uses this measurement to automatically move the lens on your camera to the
relevant position for that distance thereby adding a centre point continuous autofocus
capability to cameras that do not provide it and also, with the use of optional Tilta Nucleus
N or M motors, to manual focus lenses.

GENERAL OVERVIEW
How the AFX system’s components connect
The standard and optional components that make up the AFX system connect with a
combination of wireless and wired connections.
The primary hub of the system is the AFX main unit which contains the LIDAR sensor and
processes communications with the camera, the R1 Controller, single Tilta Nucleus N or
M motor connected to its integral interface port, the optional MMX unit to control up to
three motors and the optional Tilta Focus Wheel.
Using the optional MMX unit, the AFX can use the additional motor capability to provide
zoom and iris control as well as focus. For setup and operational instructions for the MMX
please refer to the OPTIONS - MMX section of the User Guide.
You are able to use all of the AFX’s focus controls in the same way, irrespective of if are
using it to control a native electronic lens on a Pocket 4K or Pocket 6K camera, via a
motor on its integral interface port or via a motor connected to the MMX.
All motor interface ports on the AFX and MMX use 4 pole 3.5mm cables (included) and
these connect to Tilta Nucleus N motors with the included adapter. For Tilta Nucleus M
motors, we offer adapter cables and these are connected to the EXT 2 port of the motor.

SYSTEM OVERVIEW
Battery charging and power on.
The internal battery of the AFX is charged using the supplied USB-C cable and a full
charge from flat should take approximately two hours and we recommend doing this
before following the rest of the guide. Similarly we also recommend fully charging the R1
controller, which should take approximately 60 minutes.
The AFX is powered on using the reset switch of the unit, or by pressing the Bbutton if it
is in Hibernate mode or automatically by applying USB power when the battery is empty.
Prior to using the AFX for the first time, you will need to configure it for use with your type
of camera, which is selected in the SETUP MENU.
When you power on the AFX unit, you can access the SETUP MENU during the period
that the message above is on screen by pressing the B button.
The process for selecting your camera control type is described in the next section of the
User Guide.

GETTING STARTED
Selecting your AFX CONTROL TYPE.
With the SETUP MENU open, you can now choose the type of control type you want to
use with your AFX.
IMPORTANT NOTE : As the AFX will restart and launch into the main application when
this procedure is completed, please refer to the POWER ON SEQUENCE section of this
User Guide to ensure that you have all necessary units powered correctly before
completing it. If you are using an MMX it must be active for all CALIBRATION steps.
The full description of each AFX CONTROL TYPE can be found in the AFX CONTROL
TYPE DEFINITIONS section of the MENU REFERENCE GUIDE so you should consult
that first to determine the correct one to choose for your particular system before
proceeding.
When you have determined which type to use, navigate to the AFX Control Type field
using the B button on the AFX unit and then press the A button to step through the
available options until the one you require is displayed.
To save this configuration, you should then press the Bbutton to navigate to the Restart
field and press the Abutton.
The preference will then be retained and used by the AFX until you choose to change it by
using the SETUP MENU to choose a different type.
The AFX will now restart and launch the main application."

GETTING STARTED (continued)
Bonding the AFX to your Blackmagic Pocket 4K/6K Cinema Camera.
Before you can use the AFX to control your camera for the first time, you must first
perform the initial bonding process.
To initiate this process, switch your camera on before booting the AFX, navigate to the
Bluetooth control page of its SETUP menu and ensure that Bluetooth is set to ON.
When the AFX boots with the Pocket 4K or Pocket 6K variants set as its AFX Control
Type, it will scan for the camera and automatically connect to it when it finds it.
Your camera will display a PIN number to be entered and the AFX will invoke its PIN entry
screen below.
Use the Abutton on the AFX to increase the value of the number to match the first one in
the requested PIN, then press the Bbutton to move to the next number and repeat the
process until you match all six numbers. Finally, move to the OK field and press the A
button to submit the PIN after which you should see a confirmation message on the
camera screen and the AFX will reboot and you will be able to control your camera.
If you make a mistake, simply wait for the AFX to reboot and the camera will display a new
PIN for you to try again. This bonding process is only performed the very first time you
connect to your camera and all subsequent connections will be automatically authorised.

FIRST LAUNCH - P4K/P6K Cameras Only
Overview.
To perform focus control of the lenses attached to your camera, whether electronically in
the case of the Blackmagic Pocket Cinema Cameras or physically through an attached
Tilta focus motor, each lens must have its focus positions mapped to a specific distance.
This is achieved with a semi-automated calibration process with the AFX moving the lens
to a set of focus positions, you moving the camera until the subject is in focus and, once
confirmed, the range sensor capturing the value of the distance to the subject.
This calibration procedure is performed once for each lens and the resulting data
generated is then stored in a CALIBRATION FILE in the AFX’s LENS DATABASE.
The CALIBRATION FILE is then loaded from the LENS DATABASE each time the
specific lens is subsequently used and up to 128 CALIBRATION FILES can be stored on
the AFX.
To aid with the calibration process, you can download the focus target chart above from
our website at www.cdatek.com and either print it out or display it as an image on a tablet
or monitor screen.
The accuracy of the AFX’s auto-focus performance for each lens is directly linked to the
accuracy of its initial calibration so it cannot be stressed enough that care must be taken
to follow the calibration procedure correctly and allocate a suitable amount of time to do it.
The amount of time will vary between approximately 5 minutes and 20 minutes depending
on the lens type used as the AFX uses a different number of calibration “TRACKS” for
different lens types but this will only ever need to be done once for each lens.
IMPORTANT NOTE : If you are using an MMX it must be active for all CALIBRATION steps.

FIRST LAUNCH - Lens Calibration Steps
Creating a new lens CALIBRATION FILE.
The actual process for creating a new CALIBRATION FILE is identical for both electronic
lenses on the Blackmagic Pocket Cinema Cameras and manual lenses controlled through
an attached Tilta focus motor but the process of initially invoking it will differ dependent on
which type of lens control you are using.
For the Blackmagic Pocket Cinema Cameras, the process is invoked automatically upon
the AFX detecting that you have a lens attached which does not already have a
CALIBRATION FILE in the LENS DATABASE.
If you are using a Blackmagic Pocket Cinema Camera, please skip to the next page.
For cameras using manual lenses controlled through an attached Tilta focus motor, the
process is invoked by a long press of the Abutton on the AFX unit to invoke the AFX
LENS DATABASE MENU.
With this menu invoked, navigate to the Calibrate New Lens field using the Bbutton on
the AFX unit and then press the A button to invoke the ADD NEW LENS MENU.
IMPORTANT NOTE : If you are using a Tilta Nucleus-N or M motor for focus control either
connected directly to the AFX or via the optional MMX you must use the motor’s own
calibration routine before using the AFX calibration process and when changing to a
different lens.
