2PowerBox-Systems − World Leaders in RC Power Supply Systems
Dear PowerBox-Pilot,
Our ATOM radio control system establishes a new standard in the market segment of upper mid-range systems. Based on the
considerable expertise we have gained from the CORE, together with new developments in electronics, revised software, a smal-
ler Linux computer and a revision to the method of case manufacture, we have been able to create a system which has few rivals
in terms of price : performance ratio.
The system’s crucial feature is the ingeniously simple operating system, which is exactly the same as that of the CORE.
As you would expect from PowerBox, we have allowed no compromises in the matter of redundancy: the radio system and its
power supply are of fully redundant design.
We are confident that we can guarantee our customers durability and quality at the very highest level, because we exclusively use
components of the highest possible industrial quality, produced by top manufacturers.
The entire production process – starting with circuit board assembly and extending right through to final assembly in our own
premises – takes place in Germany. Each ATOM is hand-made, and represents an example of German craftsmanship at its best!
All our staff are united in their shared aim: perfection!
We wish you many hours of pleasure and countless successful flights with your new PowerBox ATOM!

2. First Steps
• Switching on
The ATOM is switched on by holding the -button pressed in until it lights up red. Release the button briefly, then confirm the
power-on process by briefly pressing the button a second time. The transmitter is switched off in exactly the same way. The
button changes to green when the Linux system starts booting; this process takes about 25 seconds. Once the ATOM is
running, you will see the Home display on the screen: this shows fields containing telemetry values, timers, servo positions or
quck-select buttons for menus. These fields are known as widgets.
• Entering the Menu
The main menu is accessed by swiping a finger downwards from the top edge. You can now touch the left-hand menu symbol :
There is no need to press firmly, as the capacitive touch-screen simply responds to touch, like all modern smartphones. The sym-
bols in the Main menu are arranged in order of importance.
You can transfer any menu point to your own personal menu. This is accomplished simply by holding your finger on
the appropriate menu for a few seconds. When the “Person symbol” appears, the menu point is transferred into your
personal menu, which you can access conveniently using the quick-select button at the bottom of the screen. If
you wish to remove a menu point again, use the same procedure: keep your finger on the menu symbol in question,
and that entry is duly erased.
NOTE
The ATOM is fitted with a fully redundant power supply system, which is deliberately kept separate from the Linux
computer and the other processors. This means than any malfunctions in the complex Linux system cannot possibly
result in the transmitter switching itself off. The two real-time processors also function completely independently of
the Linux computer. The model remains fully controllable even if the Linux computer is pulled out when the system is
running!
NOTE

• Main Screen
1Battery indicator
The two green battery symbols indicate the state of charge
of the two internal batteries. The charge status is divided up
into five blocks, each of which stands for 20% of charge. The
charge symbols change to orange and then red if the state of
charge falls below 20% and 10% respectively. You can also
set up a telemetry widget to display the exact battery voltage.
Setting up a telemetry widget provides the opportunity to add
an audible or spoken alarm.
2Processor Status
This symbol is displayed when the workload on the Linux computer reaches a particular level. The symbol flashes briefly when
data is being processed.
3Flight Mode
This field shows the current flight phase (flight mode). The name of the flight phase can be set individually in the Flight Mode
menu.
4Wifi
This symbol is cancelled with a red line if WiFi is not active. WiFi is only active when it has been switched on manually, or automa-
tically during the Update process.
5Aerial symbols
The aerial symbols illustrate in graphic form the LQI value of the Atom’s aerials, i.e., it corresponds to the reception quality of the
return channel.

These settings are global for all models.
3.1.1. System
• Pilot name, Date and Time
Enter your name at Pilot ‘s name. You can change the name at any time. It is very important to set the correct Time of day and

Teacher / Student Vario Sequencer Differential
Telemety Controls Remove before flight

8PowerBox-Systems − World Leaders in RC Power Supply Systems
• Language
The Language setting affects the output of speech and telemetry data. When the sensors are scanned, the selected language
is sent to the sensor, which then sends back the telemetry values using the terminology in that language - if implemented.
• Units
It is also important to set your preferred units of measurement: the system sends your choice of Metric or Imperial to the tele-
metry sensors, and the sensors then deliver all telemetry values using your preferred units, such as kilometers / miles or liters /
gallons.
• Software
The Software menu will be discussed later; the transmitter and receivers can be updated at this point.
• Servo/Data
The Servo / Data setting determines whether the 3-pin output under the cover generates a PWM servo signal to act as a servo
tester, or a real-time telemetry output in the P²BUS format. The latter makes the telemetry data from the model accessible at the
transmitter itself for further processing. Typical uses of this would be for recording devices or variometers with expanded functi-
ons used for Triangle competitions.
Since Version 2.35 this socket has acted as S.BUS or SRXL input for the Teacher / Student system. These two protocols can
be generated by the receivers used by virtually all radio control systems. This allows the Atom’s Teacher / Student system to be
very flexible in operation, even in conjunction with low-cost Student transmitters made by a variety of manufacturers.
• FastStart
This feature stores the currently loaded model settings in the real-time computer when the transmitter is switched off. Next time
you switch on, you immediately have control of the model. The Linux computer boots in the usual way. Settings and trims are
only available once the Linux computer is running. This feature is extremely practical for competition work, or if you simply want
to extend or retract the undercarriage when rigging or dismantling the model.
• Telemetrie Logger
This button activates or disables the recording of telemetry data on the SD card. The default setting for this feature is ON.
• Calibration
Another important point is the Calibration menu; this is described in full at a later stage.
• System Informations
This button exports the system informations to an external memory stick.
3.1.2. Screen
Background,Color, Icons, Brightness
You can select your preferred color scheme here. The bright-
ness control should be set to a value which enables you to see
the screen content clearly and distinctly. Please note that the
screen brightness does have a perceptible effect on battery
duration!
• Dimmer
The Dimmer time setting determines the point at which the
screen is automatically darkened.
• Automatic lock
The automatic screen lock can be released again using the - button.

www.powerbox-systems.com
• Idle Alarm
Enter a time here after which you wish the transmitter to generate an alarm if the sticks have not been moved. The purpose of
this feature is to help you to avoid leaving the transmitter switched on accidentally.
• Intro
The Intro Video setting enables you to switch the brief ATOM logo sequence on or off when the system is switched on. Disa-
bling it shortens the initial boot time by a few seconds.
3.1.3. Audio
The Audio menu enables you to set different volume levels.
In the right-hand field you can set the volume to a fixed value.
However, you also have the option of assigning a rotary control
or switch for this purpose. The first step is to click on the central
field, which causes a further context window to open where
you can assign a transmitter control. All you have to do here
is move the rotary control or switch which you wish to use for
volume adjustment. When you leave the Context menu in which
you assigned the control, you will see directly in the Audio
menu how the rotary control or switch alters the volume level.
3.1.4. Wifi
If you wish to use the Online Update function, a Wifi Dongle has to be connected and the Wifi connection has to be set up. You
can use any stock Wifi Dongle with a RTL8188CU chipset. The Wifi Dongle can be connected to the USB port inside the radio.
The ATOM transmitter can be bound to your stationary router at home, or to a hotspot which you create with your mobile phone.
This means that you can even update your system at the flying field!
You will find the WiFi settings in the System settings menu. First switch on the WLAN module by pressing the OFF button.
The WiFi module in the transmitter immediately searches for all WLAN hotspots which are in range.
Select the hotspot you wish to use. You will now see the Network Password mask. Enter this, and press Connect. As soon as the
connection is made, your IP address is displayed, and the WiFi symbol at the top turns green.

10 PowerBox-Systems − World Leaders in RC Power Supply Systems
All passwords are stored in encoded form in the transmitter’s
Linux computer memory, and cannot be read out. The purpose
of the Forget button is to erase this information.
At the bottom right you will find two input fields for the Portal
login. This feature will be available as soon as the web portal
goes online. This enables you to store model files and log files
online in a cloud or to evaluate telemetry logs.
3.2 Model Menu
Select the Model button in the Main menu, and you will see
an overview of all models stored in the transmitter. You can also
set up, rename or erase models and model folders.
At this point you can also store pictures (215 x 100 pixels, *.jpg
or *.png) for your model, and reset the model operating time.
The Export function makes it swift and simple to export a model
file onto a USB memory stick.
To create a new model, briefly touch the + button at the bottom
of the screen. Assign a name to your model, and confirm your
choice with OK. You will now see the Select screen for the
model type. At this point you can select the appropriate model
type, with the additional options of delta wing and V-tail.
Do not delete the Deme model. If all models are deleted the radio cannot start!
NOTE

11
www.powerbox-systems.com
On the next screen you select one of the ranges on the right-hand side, e.g. Wing. The screen now shows a diagram of a wing
corresponding to your chosen type. If your configuration is more specialized, that presents no problems: at a later stage you can
very easily program individual functions manually.
Briefly press Control, and move the aileron stick to select the Aileron control in the Context menu. Now you select a transmitter
control which is to control the left aileron; this will be the left or right primary stick, depending on the transmitter mode you prefer.
The software of the ATOM has no modes – it is only the mechanical settings of the transmitter sticks which determi-
nes the stick mode.
NOTE
If you now leave the Select screen again, you will see that the same transmitter control has also been assigned automatically to
the right aileron. The next step is to select the servo outputs to which you intend to connect the aileron servos; this is accomplis-
hed by pressing +. Note that you can assign up to eight servos to a single function.
If your model is an aerobatic aircraft, you would naturally select two or three servos at this point, if you have multiple servos me-
chanically connected to a single control surface. At a later stage you will be able to set the travel, direction of rotation and center
position for each servo separately. If these parameters are too coarse for your application, you can set an individual curve with up
to 17 points for each servo.
Back in the Assignment screen it is also possible to rename the functions to suit your own preference.
If you decide to assign the wing flaps at this point, you will learn to appreciate one of the truly unique features of the ATOM. As
with the ailerons, you again assign a transmitter control to the flaps. If each flap is operated by a separate servo, you won’t notice
anything unusual: you simply assign the flaps to your preferred servo outputs. However, if you also want the ailerons to double as
flaps, or want the ailerons to be mixed in to the flaps, you also assign the aileron outputs to the flap function. These functions are
now superimposed, i.e. the mixing is accomplished simply by assigning the servos. At a later stage you can adjust the servos
individually, both for the Aileron function and the Flap function. Servo travel, center and direction can be set separately for both
functions!
An even clearer example of this exceptional feature relates to models with a Delta wing. If you select a delta using the Assistant,
the correct functions are assigned automatically. To clarify this, the manual method would be as follows:
As an example, servos 1 and 5 are assigned to Aileron. Servos 1 and 5 are also assigned to Elevator. Since the servos are
installed in a mirror-image arrangement, it is logical that the servos always operate as ailerons, regardless of whether the pilot
moves the elevator stick or the aileron stick. Now we switch to the Elevator function and reverse the direction of rotation of one
servo. The elevator function now works correctly, but the “reversed” elevator function has no effect on the servo direction when an
aileron command is applied, i.e. the ailerons still work correctly. That’s all there is to setting up a “Delta mixer”.

12 PowerBox-Systems − World Leaders in RC Power Supply Systems
Back to our Wing screen: when all the assignments are complete, press the button, amongst the quick-select buttons at the
bottom in order to return to the overview. You can now continue assigning transmitter controls and servos to all the remaining
assigning transmitter controls and servos to all the remaining functions. When everything is finished, touch Continue at bottom
right. The functions and servo assignments are complete.
3.3 Function Menu
You now arrive at the most important screen display: The
Function overview. In principle, the set-up of the whole mo-
del is carried out from this starting point. The display is arranged
logically from left to right:
Function > Control > Trim > Setup > Failsafe > Servo(s)
The individual points in detail:
3.3.1. Function
Each function always contains a transmitter control, the associated trim, the settings for the transmitter control – such as Expo
and Travel, Failsafe or Hold – and the assigned servos. Each function can also be renamed just as you wish at this screen: simply
touch the Function name.
3.3.2. Control
Here you can assign a transmitter control or a fixed value to the
function. The transmitter control can be a stick, a slider, a rotary
control, a switch or a button.
3.3.3. Trim
• Flight Mode
Here you can select whether the effect of any trim adjustment
is to be Global – i.e., the trim value should be the same in all
flight modes – or Single – i.e., the trim value should be variable
separately in each flight mode. The method of using flight
modes is discussed later.
• Trim Control
It is necessary to assign a trim control as the first step here.
This can be one of the four trims located adjacent to the pri-
mary sticks, or two of the four rubberized push-buttons. If you
select the push-buttons, the buttons always work together left
and right as the trim.

13
www.powerbox-systems.com
• Trim Mode
You can choose any of four different trim modes. The stan-
dard one is Offset mode: In this mode a trim adjustment
affects the entire range of stick travel, i.e. including the
end-points. Alternative trim modes are Left and Right;
typically, these are intended for idle adjustment in the case of
engines and turbines. In the Center trim mode any adjustment
only affects the center range, i.e. the end-points remain
unchanged.
• Trim Range
At this point you can limit the permissible trim range. The
percentage value defines the max. throw which the trim can move.
• Steps
Here you can set the number of trim steps or increments; not the size of the step.
If you alter the Min./Max. values, the increment size also changes - assuming that the number of increments remains
the same.
NOTE
• Direction
Here you can set the direction of the trim control; for example, you may need this function in connection with the trim buttons.
• Signal
At this point you can set whether the trims are to generate an audio signal when they are adjusted, or when they pass through
the center point. A vibration signal is also available.
3.3.4. Setup
At this point you can adjust the transmitter control input, Expo, transit time and curves.
• Flight Mode
If you want the adjustments you make to affect all flight modes, set this menu point to Global. If you set this point to Single,
you can carry out individual adjustments for each flight mode separately. This tool is extremely powerful, but if you wish to make
use of it, you must first create flight modes – more on this later. Once you have set up the flight modes, all you need to do is ac-
tivate them, then enter your preferred adjustments for the transmitter control concerned. The transmitter control settings (travel,
curve, etc.) which you enter for, say, the “Landing” flight mode, will then have no effect in the “Thermal” flight mode.

14 PowerBox-Systems − World Leaders in RC Power Supply Systems
• Transmitter control Rate
Here you can select a transmitter control which switches the rate on and off, or sets it to linear. The transmitter control can be
any of the primary sticks, proportional controls or switches.
• Rate
The purpose of the Rate button is to adjust the travel of the transmitter control. If you select nothing for Transmitter control
rate, the value is fixed. If you assign a transmitter control to Transmitter control rate, you can set different values on three
levels. The level initially selected with the transmitter control you have selected is shown in green. If you select a proportional
control as transmitter control, the values are applied in a linear fashion within the three levels.
• Transmitter control expo
At this point you can select a transmitter control which is used to switch an Expo characteristic, or set it to linear. You can choo-
se any transmitter control from the primary sticks, proportional controls or switches.
• Expo
The purpose of the Expo button is to adjust the exponential factor. If you select nothing for Transmitter control expo, the
value is fixed. If you assign a transmitter control to Transmitter control expo, you can use it to set different values on three
levels. The level initially selected using the transmitter control you have selected is shown in green. If you select a proportional
control as transmitter control, the values are applied in a linear fashion within the three levels.
• Curve editor
he curve editor is used to set up special curves, for example,
to program throttle curves.
- The first step is to select the number of points: up to 17 can
be specified.
- Use the arrow buttons to select the point which you wish to
move; the selected point changes color to green.
- Adjust the percentage value to shift the point up or down.
- The Smooth option can be used to even out the curve, and
thereby avoid jerks in the servo’s response.
- Raw removes the effect of the curve smoothing.
• - Reset curve resets the curve to linear travel.
• Transit time
At this point you can set two transit times: one determines the servo transit time to the left, the other to the right. The time in
seconds determines how long the servo takes to move from one end-point to the other.
3.3.5. Hold / Failsafe
If you want a servo to take up a pre-determined position in case
of radio signal loss, you should select Failsafe here. The Learn
button now appears, enabling you to store the current position
in the receiver.
The receiver or receivers do not need to be bound at
this point. The Failsafe positions are repeatedly trans-
mitted to the receivers at regular intervals.
NOTE

15
www.powerbox-systems.com
3.3.6 Servo
Here you will find the assigned servos again. Up to eight servos
can be assigned to each function. As already mentioned in the
Assistant, the travel and end-points of each servo can be
adjusted separately here. Any adjustments you make to a servo
at this point have no influence on the settings of the same servo
if it is also assigned to another function. This provides a simple
means of mixing in aircraft with multi-flap wings, delta wings and
V-tails.
• If you wish to adjust a servo’s travel or center position, the first step is to touch the appropriate button; you can now adjust the
value. As soon as you move the associated stick, the Select button shifts to the corresponding position. This means that you
do not need to select Left, Right and Center when adjusting the control surface; instead, you select each point very conve-
niently using the transmitter stick, altering the position of the control surface using the arrow buttons at the bottom of the screen.
At the same time, you can observe the effect of any change directly on the servo.
• Servo number
Indicates the receiver output at which this servo signal is present.
• Servo name
The servo name can be changed individually. Hold your finger on it to open up the keypad.
• Limit
Works like a mechanical stop – the servo does not move beyond the set point.
• Way
Adjusts the servo travel.
• Center
Offsets the servo center position. Acts like a “mechanical” center offset – it also affects the end-points.
• Direction
Reverses the direction of rotation of the servo.
• Curve editor
The travel of each servo can be adjusted using a 17-point
curve to match the mechanical installation even more accu-
rately. The most common use for this function is to match
servos to each other where they are mechanically linked
(servo matching). At top right you will see the name of the
servo whose curve you wish to adjust, and the function which
the servo controls. If you alter the servo curve in the selected
function, the change will have no effect on the travel which
you have set for the same servo in other functions.
- Center
The Center button is used to set a center offset which affects the whole of the servo’s travel. You will see the effect of the
change immediately in the graph on the left-hand side.
- Curven Editor
Press Edit, when you wish to adjust servo travel using a maximum of 17 points.

16 PowerBox-Systems − World Leaders in RC Power Supply Systems
This is the procedure: use the arrow buttons to select the point you wish to adjust. Briefly press the displayed setting at Value,
then adjust the servo for this position. The Smooth button can be used to even out the course of the curve. Right at the bottom
you will find a Reset button which sets the curve back to a straight line. Once you have set the desired curve, return to the Ser-
vo Curve menu, where you will find three Preview buttons:
- Servo curve
This displays the shape of the pure servo curve.
- Function curve
This displays the shape of the pure function curve. If you have
already set up Expo or Dual Rates, this will be shown in this
view.
- Result
This displays the net result of the function curve and the servo
curve.
If you wish, you can reset the servo curve once you
return to the Servo Overview. If you accidentally find
yourself at the Reset button, that is not a problem: sim-
ply select the Curve Editor again, and the curve will still
be present there with the settings you last selected.

3.4 Binding a receiver
Select the Receiver button from the Main menu. As you will
now see, up to two receivers can be bound to the ATOM
simultaneously.
It is even possible to use different types of receiver; for exam-
ple, one PBR-9D and one PBR-5S can be bound. All two
receivers are of “equal value”, i.e. there is no Master / Slave
assignment, and no restrictions in terms of telemetry. Teleme-
try sensors can be connected to all four receivers, all of which
send data to the ATOM on an equal footing.
The receivers are identified by the four capital letters A to D. The same letters appear in the telemetry data sent from the receivers,
helping to differentiate between them.
3.4.1. Binding
There are two methods of binding receivers:
• Option 1
Connect a power supply to the receiver, and it will respond by flashing green at high frequency for ten seconds. Press the Bind
button on your ATOM transmitter, and the receiver now binds to it; the LED lights a continuous green.
If you do not press the Bind button within the ten-second period, the LED switches to flashing slowly red – at this point the
receiver can no longer be bound to the transmitter. You can only re-start the process if you first disconnect the power supply.
• Option 2
Press the Bind button on your ATOM, then connect the receiver to a power supply. The LED switches to continuous green
once the receiver is bound.
Technical information: during the binding procedure the PowerBox ATOM generates a random sequence from a total
of more than 32 million numbers; this is then used as the basis for calculating the hopping sequence and encoding
the signals. The likelihood that two identical codes could be generated is therefore very close to zero.
NOTE
3.4.2. Remove
The Remove button has an important function: if you wish to uninstall a receiver from a model, it is essential to remove that recei-
ver from the model memory beforehand using this button. If you simply uninstall the receiver without first removing it at the trans-
mitter, then the other bound receivers will not work when you next switch the system on. This is an important safety feature, as it
ensures that all the bound receivers are working when you switch the system on, i.e. before you take off!
3.4.3. Range check
The Range check function reduces the transmitter’s output power, thereby simulating a large distance between transmitter and
model. This enables you to determine any possible weaknesses in reception in the receivers. In range check mode all the con-
trols should work perfectly at a range of at least 50 m. During the Range Test you can see the values for Link Quality (LQI). This
enables you not only to see whether the radio link is working, but also the quality of the link. This can be helpful in determining the
optimum aerial positions in the model before you fly it.

It is possible to adjust settings such as channel shift,
frame rate, iGyroSAT and others at the receiver itself.
These settings are usually accessed using a Telemetry
widget, but are also available if you press the receiver
image in the Bind menu.
NOTE
3.4.4. Selecting ATOM/M-Link
If your transmitter is equipped with a supplementary Multi-
plex M-Link aerial, you will find the button for switching from
the ATOM system to the M-Link system right at the top.
The M-Link system offers two binding modes:
• Bind 12K
14ms frame rate, 12 channels
• Bind 16K
21ms frame rate, 16 channels
Choose your setting. If you do not need more than twelve channels, you should always give preference to Option 12K, as the
servos are addressed at a higher rate in this mode. This can be advantageous in respect of smooth running, transit speed and
precision. In contrast, Option 16K offers sixteen channels and a slower frame rate; this is the best choice for use with older
servos.
Your choice applies to the current model, and is stored in the model file together with the relevant Bind information. If you change
the setting for a model which has already been bound, you will need to re-bind the receiver!
3.5 Differential
The Differential function is a simple method of setting up differential aileron travel. It is possible to set differential as a fixed value,
assign it to any transmitter control or trim, and also set different levels for individual flight phases. These features enable you to
adjust the degree of differential accurately in flight. To set up differential, select the Differential menu point, and you will see this
screen display. Press the +button, and select from the list the function to which the differential should apply:

– The next step is to select the servos which the differential travel is to affect:
– Now briefly press the button under Diff. Value in order to set the percentage value, or to assign a transmitter control for
adjusting the value. As the screenshot shows, you can also see any Expo values which you have already set..
• Setting up differential using a fixed value:
Enter a fixed value at Diff. Value. This value can also vary according to flight phase, if you select Single at the Flight Phase
point..
• Assigning a transmitter control
Briefly press the On button after the Diff. Control field. In this example the right-hand slider has been assigned to in-flight diffe-
rential variation. Once the optimum value has been found, you can later set it as the fixed value.
• Assigning a trim
The Diff Control must be set to On. Now briefly press Diff. Trim to select one of the trims.
The trim controls are the ideal choice if you wish to set differential settings which vary for each flight phase. With this option the
differential value you set always applies to the currently selected flight phase. This only works if the button after Flight Phase is
set to Single.

In the overview you will now see the relative percentage travels of the servo outputs.
3.6 Virtual Switches
The virtual switches can be used to digitize linear transmitter controls by setting up a switching threshold to generate a switched
state. It is also possible to set up a logical link between two or more switches or linear controls. This facility can be used as a very
easy method of implementing functions such as safety switches for electric power systems.
Select the Virtual Switch button in the menu, then press +to set up a new virtual switch. You can rename the virtual switch
by pressing the switch button. As you can see, this field includes a small triangle at top right. This means that a function can be
selected here by holding your finger on it. In this case the virtual switch can be erased again by holding your finger on the switch
button.
First select a transmitter control by briefly pressing the blank field (three dashes) under Control; press Control again at the next
screen. You can now select a switch or linear control as transmitter control by operating it.
Do not assign this function to a trim which is already associated with one of the primary functions!
