computer radio control system
1 Introduction

1.2 DS-14

1.1 DC/DS
The DS-14 hand-held transmitter expands the range of model
transmitters equipped with the JETI Duplex system, this new design
is based on the high-end model DS-16. Unlike the DS-16, the DS-14
offers a unique concept of individual feature setup based upon the
requirements of each customer. The transmitter is available in a basic
configuration that will meet the needs of most users for most model
types. For individual setting of the transmitter there is a configurator
available at swshop.jetimodel.com. After the simple registration of
your transmitter it is possible to select additional features based
upon your individual demands. For example, if you fly only
helicopter models, select such features as "Throttle Limiter" or
"Gyro Settings" but you will probably not need to increase the
number of flight modes. These are more suitable for controlling
glider models.

The DC/DS transmitters were developed and produced with the
cooperation of professional and world champion pilots. These
transmitters were created with the goals of maximum utility, simple
handling, maximum durability and the ultimate reliability of their
mechanical parts. The metal case, with its chemically resistant
outside surface treatment, provides maximum protection for the
interior components. The straightforward case shape makes
servicing easy. The metal, quad ball bearing equipped, stick gimbals
with their magnetic Hall sensors are another revolutionary design
concept used to make the DC/DS among the world’s most advanced
R/C systems.
Purposefully placed at the top of the transmitter, the 3.8“ backlit LCD
display with its wide viewing angle offers nearly perfect visibility in
just about any lighting condition. Thanks to its high resolution
display and use of a relatively large number of graphic images it was
possible to create a simple and intuitive setup procedure for
displaying telemetric data.

The DS-14 features newly designed gimbal sticks. We managed to
keep all the characteristics of the full metal sticks used in the DS-16,
mainly thanks to high-quality materials and Hall sensors inside the
sticks which are fully supported by high quality ball bearings.

The DUPLEX EX family of products have been equipped with an
improved telemetric data transfer system which can be viewed on
the LCD transmitter display or saved for later analysis on a PC. The
transmitter allows the setup of audible notifications (optionally
created by the user), which can be related to actual telemetric values
or to sound alarms or signals which have been assigned to
conditions of various control elements.

As a result, the DS-14 becomes a powerful tool with the possibility to
individually select many features at a very attractive price.

1.2.1 Activation method for software modules of JETI model

generated. It will then be sent to your e-mail.

1. Make sure you have the most current firmware version in your
transmitter.

6. Connect the DS-14 to your computer and enable USB mode.
7. Copy the “Activation.bin” file to the transmitter SD card into the
root folder. The contents of the transmitter SD card can then look like
this:

2. Register on swshop.jetimodel.com.
3. After clicking on the „Register
new product“ button you will be
redirected to a form where you
enter a product type (DS-14),
followed by the „serial number”
(SN: xxxxxxxxx) (to be found on the
back of the transmitter behind the
screen) and then enter the „16
digit registration code” (xxxxxxxx-xxxx-xxxx) (see the menu
„System -> Installed Modules”
highlighted by the frame). After
registering your transmitter, you
can select individual function
modules that you want to activate.

8. Disconnect the transmitter from the computer (Do not forget to
confirm the safe hardware removal). Then confirm in your
transmitter that you want to update and restart it.
If the activation is successful, an informative table with a list of
modules appears immediately after switching on. Then it is
possible to operate the transmitter as usual.

4. Mark selected modules and
proceed to checkout.
5. Then you will be asked to pay
the relevant amount. Af ter
payment, a unique
nontransferable file named

DC/DS transmitters (2- or 3-position) can be easily moved and
assigned to create a custom configuration that works best for your
application.

Transmitters - these designs emphasize use comfort, state-of-theart appearance and use premium quality materials.
Precise Gimbals – the transmitter gimbals are equipped with Hall
sensors and ball bearings for precision movement with an almost
unlimited lifespan.

Programming – the logical and intuitive transmitter firmware is
designed to be simple to use. Just follow the step-by-step screens.
The creation of a new model can be accomplished with just a few
easy steps.

resolution which is highly visable under any light conditions.
Li-Ion Battery – provides a proven and reliable energy source with a
high capacity (3200mAh) and a long service life.

Sounds/Alarms – the DC/DS transmitters are equipped with audible
alarms and also allows the use of user-recordable alarms and sounds
to keep you fully informed while also keeping distractions to a
minimum. "

Easy Charging – simply connect the wall power supply to the
transmitter. The DC/DS may also be charged through their USB to PC
interface.The charging progress is shown on the DC/DS display.

Depends on equipment - The specific function is available if the
corresponding module is activated. The DC-16 and DS-16
transmitters in their basic version have all the modules activated on
maximum possible values. With the DS-14 transmitter it is possible
to take advantage of the system that enables purchasing of the

Integrated Antenna – the antennas are located behind fully
integrated covers in both the DC-16 and DS-14/16 cases for
protection against mechanical damage.

3. Carefully hold the switch by its printed circuit board assembly
and slowly pull it out. Use this method to also remove and
exchange all of the other switches. After re-assembling and
turning on your transmitter the software will sound a warning
reminding you that you have executed a change. Always reinspect all assigned functions of the switches before
attempting to fly.

3.5 Digital Trims
Transmitter gimbals are used for controlling the basic flight
functions like throttle, roll(aileron), pitch(elevator), and yaw(rudder).
Immediately under the transmitter gimbal sticks you can see four
push-buttons which are the programmable, digital trim buttons.

The digital trims are used for fine trimming of the flying model. When
the transmitter is turned off, the trim values are stored in memory
and are recalled when the system is turned back on.
Every model has its own trim setup. Also all flight modes may be
configured to use different trim configurations. By pressing one of
the buttons, the screen will automatically change to display the
graphic position of that trim. The transmitter trims feature an
acoustic step and centre beep alarm.
In the „Digital trim“ menu it‘s possible to enable a special
function used as automatic trimming. Digital trim steps and trim
range setting is explained in „Main menu->Fine tuning/flight
modes->Digital trim“

transmitter LCD display shows the status and condition of the
battery pack. The Li-Ion battery is factory installed.

3.6.1 Charging
The DC-16 transmitter can be charged with the included wall power
supply or through the built-in USB port.
For fast charging use the included wall power supply. Charging time
is around 3 hours. During the charging process the transmitter can
be in switched-on or off position. The charging status is clearly
shown by lit red and green LEDs. If the transmitter is switched on
during the charging process you can see the charging progress
directly on the LCD display.
Transmitter Charging:
1.
Plug in the included power supply to a wall outlet.
2.
Plug the main charging connector into the transmitter. If the
green LED goes out, the transmitter is not fully charged. The
red LED indicates the battery charging status.

Note: If the transmitter battery has been disconnected for
longer than 1 minute, the time, and date will be deleted.
Warning: DC-16 transmitters should only be operated only
with original or manufacturer approved battery
packs. The use of other battery packs will void the
warranty.

selected model no longer matches.

4.6 Digital Trims
Transmitter gimbals are used for controlling the basic flight
functions like throttle, roll(aileron), pitch(elevator), and yaw(rudder).
Immediately under the transmitter gimbal sticks you can see four
push-buttons which are the programmable, digital trim buttons.

Note: When replacing the switch Sa it is also necessary to
remove the switches Sb and Sc from the transmitter
body.
When replacing the switch Sc it is also necessary to
remove the switch Sb from the transmitter body.
When replacing the switch Sh it is also necessary to
remove the switches Sg and Sf from the transmitter
body.
When replacing the switch Sf it is also necessary to

4.7.2 Battery Replacement

4.7 Transmitter Battery Pack

Should you decide to replace the transmitter battery, please follow
these steps:
1. Switch off the transmitter and remove the 8 screws that
secure the radio back cover. Next, remove the radio back cover.
2. Disconnect the transmitter battery connector.
3. Loosen the battery fastening strap and remove the battery.

The DS-16 transmitter is powered by a Li-Ion type battery pack and
comes equipped with its own built-in advanced battery
management and charging circuit. In switched-on position, the
transmitter LCD display shows the status and condition of the
battery pack. The Li-Ion battery is factory installed.

4.7.1 Charging
The DS-16 transmitter can be charged with the included wall power
supply or through the built-in USB port.
For fast charging use the included wall power supply. Charging time
is around 3 hours. During the charging process the transmitter can
be in switched-on or off position. The charging status is clearly
shown by lit red and green LEDs. If the transmitter is switched on
during the charging process you can see the charging progress
directly on the LCD display.
Transmitter Charging:
1.
Plug-in the included power supply to a wall outlet.
2.
Plug the main charging connector into the transmitter. If the
green LED goes out, the transmitter is not fully charged. The
red LED indicates the battery charging status.

Note: If the transmitter battery has been disconnected for
longer than 1 minute, the time and date will be deleted.
Warning: DS-16 transmitters should only be operated only
with original or manufacturer approved battery
packs. The use of other battery packs will void the
warranty.

• Discharged battery – red LED is slow blinking, the green LED
is OFF
• Close to full charge – red LED is permanently ON, the green
LED is OFF

• Fully charged battery – the red and green LEDs are ON

the „Instructor“ mode, the primary RF module communicates
with the model and the secondary RF module communicates
with the student’s transmitter. In the „Student“ mode the
DC/DS transmitter communicates via the primary RF module
with the instructor’s transmitter. If you operate two of the
DC/DS transmitters, one of them in the „Instructor“ mode and
the other one in the „Student“ mode, the transmitters
communicate between each other via dedicated RF
transmitter module. With this advanced system NO additional
equipment is necessary.

5 RF Transmitter Modules
In order to achieve the highest transmission quality and reliability of
the DC/DS transmitters, we have decided to equip the radio with two
independent DUPLEX 2.4GHz transmitter modules. The transmitter
modules have separate antennas. From the point of transmission
they are fully independent from each other. The RF modules of the
transmitter can operate in following modes:

•

„Default“mode – the primary and secundary transmitter RF
modules are active. Both modules alternately communicate
with the receiver. This improves safety and helps to cover dead
angles as well.
„Double Path“mode – the transmitter RF modules
communicate independently from each other with two
different receivers. The receivers can be interconnected via an
intelligent synthesizer, for instance the JETI Enlink, or the basic
control functions can be divided between two independent
receivers. In this mode one part of a model can be controlled
with one receiver using the first transmitter RF module, the
other part of a model with a second receiver and the second RF
module. In an instant you have created a dual, redundant
flying system with two receivers and two RF modules.
This greatly improves safety and reliability since both RF
modules alternate their communication with both receivers.
„Trainer“mode – one of the RF transmitter modules is
assigned to communicate with the instructor/student
transmitter only. Communication with the model takes place
via instructor’s transmitter only. If the DC/DS transmitter is in

Bind transmitter with the receiver, see chapter 8.4 Receiver->Binding.
Once your transmitter has been bound with the receiver and you have
re-applied power to the receiver, the last setup phase is the tuning of
your servo output functions, see chapter 7.3.4 Setup of receiver
outputs.
With this type of wing configuration there is usually a mixer used to also
raise the ailerons as spoilers (spoilerons). Follow the steps below the set
up this mixer. In this example we will use the „right side control
lever(5)“ for the proportional control of the spoilerons.

5. This page displays the flight control
functions and their transmitter switch
assignments. Here you can verify that your
flight control functions are correctly assigned
to the transmitter switches/sticks. If they are
not, check and make sure that you have
selected the proper transmitter mode.
Confirm the assignments by pushing the
„F5(Next)“ button.

,select „Switch“ and push the „3D button“
again. Next, move the „right side control
lever(5)“. Confirm with the „F5(OK)” button.
The last step in this menu is to set the amount
of travel that your ailerons will move as
spoilerons (or flaperons) and to set any
desired elevator compensation.

menu item „Position of front servo“ to
„Rear“ – the swash plate servo orientation
will be turned 180°. Confirm the change by
pressing the „F5(Next)” button.

First it is necessary to create a model in the transmitter and then bind
the DC/DS transmitter with the receiver which will control the given
model. See chapter 8.3: „Receiver->Binding”.
Notice: For safety reasons we strongly recommend removing the
main/tail blades or disconnecting the motor when working
with an electric helicopter.

computer radio control system
When you create a new helicopter model, you are required to define
the swash plate configuration for the model. Please refer to your
helicopter’s instructions and verify that you have the correct swash
plate configuation. If you find that you need to change your swash
plate configuration, you can always go to the „Model -> Basic

First it is necessary to create a model in the transmitter and then bind
the DC/DS transmitter with the receiver which will control the given
model, see chapter 8.3: „Receiver->Binding”.

7.3.3 General
The DC/DS transmitter are not only equipped with the assistants for
airplanes or helicopters, but they also have a „General“ assistant
which can be used to create just about any other type of model. If
your model cannot be assigned to the category of an airplane or
helicopter, select the general model. The following setup describes
the creation of a boat model. This process could also be used to
create a profile for any other land/water/air model craft. In this
example, the model is controlled by basic functions like throttle and
rudder as well as by extended functions like a motor sound
generator, lighting system, siren, and a smoke generator. The first
three above mentioned functions are controlled proportionally and
the rest are non proportional.

1. Switch-on the transmitter. In the main
display push the key „menu“. Select the

computer radio control system

7.3.4 setup of Receiver Outputs

Once your transmitter has been bound with a receiver and has been
connected to its power supply, the last step consists of tuning the
servo output functions, see chapter 7.3.4: Setup of receiver
outputs.
To complete this model we just need to configure a free mixer from
the throttle function to the motor sound module. In this example we
will set a switch to enable/disable the mixer so that when the switch
is „on“, the motor sound module is controlled with the throttle
(motor speed). Go to the „Fine tuning -> Free mixers“ menu.

Go to the „Model->Servo Setup“ menu. Use the „F2“ and „F3“
buttons to brows through the receiver outputs (channels).
You can scrol through the following servo adjustment items for each
channel:
„Servo reversing“ – reverses the servo throw direction.
Move the stick for your selected channel and observe the direction
of the servo movement. If the servo moves in the opposite of your
desired direction, change the direction by editing the „Reverse“ item
for that particular servo. Continue with each channel until all of the
servos travel in the required directions.

a. Use the „F2(Add)“ button to create a
new mixer. Select „Engine“ in the „From“
item. Then select „Sound M“ (the name of
the sound function) in the „To“ item. The
item „Master Value“ represents the
amount of mixing from the input function
to the output function for this mixer. With the „F5(Next)“ button you
will create the mixer and the display will change to show the
overview of your programmed free mixers.

„Center (Subtrim)“- adjusts the center position of each servo’s
output.
With your sticks in their neutral positions, scroll through each servo’s
page and use the „Center (Subtrim)“ item to correctly set all of your
servo‘s center or neutral positions.

b. To assign a switch for the activation and
deactivation of the free mixer, press the
„F4(Edit)“ button. Select and edit the
„Switch“ item to assign a switch/stick to
enable/disable the mixer.

Note: You should mechanically adjust all of your servo arms and servo
linkages to be as close to neutral or center as possible so that you
will need as little subtrim as possible. Using large amounts of
subtrim can limit the overall throw of your servo.

computer radio control system

„Max/Min. limit“ – sets the absolute maximum servo output throw
Use these to limit the maximum range of servo throw in order to
keep your servos from exceeding their mechanical limits or to keep
your servos from binding when moving their arms or linkages to
their full travel. You should use the dual rate function to set your
model’s useable control throws.

5.
A1/A2 - receiver antennas. The antennas should be installed
so that the wires form a 90° angle relative to each other.

8.1 Description

8.2 Installation
3

Whenever possible, you should wrap the receiver in foam and place
it as far as possible from sources of interference (servos, electric
motors). Arrange the receiver antennas so that their active ends form
a 90° angle and try to put them as far as possible away from each
other. Take care not to bend them with a radius smaller than 1 cm.
The active part of the antenna should not be placed close to metal
parts. If your model has a carbon fuselage it is very important to
place the active antenna ends outside the fuselage.

1.
JETI Duplex receivers use the universal or „JR Type“ servo
connectors.
2.
Bat - receiver and servo power supply input. Whenever
possible, always supply power to your receiver using more than one
of these inputs. You can either supply power through the use of a Ycable or through any unused receiver channel connection. To power
the receiver you may use NiCd packs, the BEC from your ESC or Li-xx
cells used with a voltage regulator, such as the JETI MAXBEC or
similar.
3.
SAT - auxillary input/output for PPM signals. This input allows
you to connect an additional JETI DUPLEX Rsat2 satellite receiver or
an additional US version Duplex receiver.This allows you to increase
the number of receiver antennas in your system for increased
reliabilty in installations with shielded or badly oriented antennas.
4.
EXT - input for telemetry sensors. If you want to connect more
than one telemetry sensor then use the JETI EXPANDER E4. You can
„daisy-chain“ several of the E4 Expanders to support many, many
sensors.

8.3 Binding
In order to achieve communication between transmitter and
receiver you must bind them. During this process the transmitter
learns the receiver address and will automatically find it again when
switched back on. Communication begins with this receiver
automatically if the transmitter is not already communicating with
another receiver. The binding process needs only to be done once
for each receiver.

8.4 Range Test
The range test will verify that the transmitter and receiver are
functioning properly.
Before the first flight of each flying session or if have any doubts
about the transmitter or receiver function, you should always check
the range. During the range test the transmitter’s output power is
decreased to 10%.
When performing a range test, both the model and the transmitter
should be at a minimum height of 80 cm (31.5“) above the ground. A
correctly functioning transmitter and receiver in range test mode
should safely control a model to a minimum distance of 50m (164‘).
If not, check your model’s antenna installation first. If the test is still
not successful, don´t fly the equipment and contact your retail shop
or one of the JETI authorized service centers.

1. Turn off the receiver. Keep the transmitter turned on.
2. Plug the "BIND PLUG" into the EXT receiver input.
3. Connect receiver power supply.
4. Locate the transmitter menu „Advanced Properties -> Wireless
Modes/Trainer”
5. Highlight "Pair primary TX module" and press the „3D button”.
6. The receiver will bind with the transmitter. Confirm the registered
device.

8.5 Fail safe
All Duplex 2.4GHz system receivers are equipped with „fail safe“, a
function which reacts to control signal transmission interruptions.
When your receiver for any reason does not receive transmitter
information, it changes, after a pre-set time period, to one of the
following modes.
„Repeat“ – This mode holds the last valid control throw signal ( this is
the default mode for all receivers)
„Out off“ – There is no output signal provided by the receiver, i. e.
servos do not keep their positions
„Failsafe“ – receiver outputs change to preset positions
56

computer radio control system

Each receiver channel can be configured to one of the modes
described above. We recommend that you setup „fail safe“ positions
for every output, which enables your model to stay in a stable
condition. For instance, the elevator and rudder in neutral positions,
electric motor switched-off, gas engine idling, spoilers extended.
Configuration Method of the receiver failsafe function.
1.
Bind receiver with transmitter. See chapter: 8.4 Binding. Leave
receiver and transmitter in switched-on condition.
2.
In the transmitter, go to the menu „System->JETIbox“ and
proceed according to picture. Use the F1-F4 function buttons to
move within the menu.
3.
In the „Set Output Pin“ menu select the receiver output which
you want to configure (use the left/right buttons) and proceed (by
using the down-button).
4.
In the „Signal Fault Yn“ menu where n denotes the channel
number which has to be configured, use the right-button to edit the
output function showing a signal failure (setup „fail safe“). You have
now activated the „fail safe“ function on receiver channel output n.
5.
The „fail safe“ is adjusted by pressing the down-button and
changing to the „fail safe“ menu. With the left/right buttons edit the
„fail safe“ value in a range of 0.8ms to 2.2 ms. Adjust all of the
connected receiver outputs by repeating steps 3-5.
The last parameter to be set up is the elapsed time after signal failure
when the „fail safe“ or other actions after signal failure will be
initiated. In the „SignalFault Delay“ menu you can define the length
of time after a signal fault occurrs in which the preset throws are
applied. The values in this menu are changed by pressing the
left/right buttons.

In the picture above, two receivers – R8 EX and R9 EX – have been
detected and are recognized. When you press the rotary button, you
are able to configure them in detail. Here is the example how to use
the Device Explorer to configure an "R8 EX"receiver:
First, the transmitter downloads all settings from the receiver. After
that operation is completed you should be able to see the basic
configuration of the receiver as shown in the picture a). Every
modification that you make is automatically uploaded back to the
receiver, so that you can immediately see results of the steps you are

8.7 Using Device Explorer To Configure the Receiver
The Device Explorer utilizes the latest
data/command EX Bus protocol to
wirelessly configure remote devices such as
receivers, sensors and other EX Bus
compatible devices. You can check the
label of your device to see if it supports the
EX Bus protocol.

Basically, the Device Explorer (located in
the Model menu) replaces the integrated
JETIBOX emulation and brings additional,
more intelligent ways to communicate
with your remote devices. The main Device
Explorer window shows a list of available
devices. The recognized devices are labeled with their registered
name, others are not displayed or only displayed as a device ID. The
check mark tells you that the device is ready and that you can
configure it. By using the „F3" Refresh button you can reset the
displayed devices, this forces the auto-detection function to explore
all attached devices. The remote sensor and device detection
process is always running in the background.

doing and there is no need to continuously "save" your changes. For
your convenience, there is a "Refresh" button „F3", which causes all
of the data to be downloaded from the receiver once again. This is
beneficial mainly if you are modifying the configuration by using a
JETIBOX device and the Device Explorer simultaneously.
The "F2" Tools button is used to enter a special dialog where you can
import and export settings of the particular device. If you want to
export the configuration of your (for example) receiver, just enter the
"Export settings" menu item, set the file name and confirm.
Similarly you can import this configuration to the device. All the
exported files are stored in the "Export" folder on the SD card.
60

computer radio control system

- Reset to factory settings... – After confirmation, the receiver's
configuration will be restored to its factory settings.

Note: Before a device can be recognized, a special predefined
configuration scheme must be present on the SD card in the
/Devices folder. If the scheme doesn't match or doesn't exist, an
error message "Unknown device" is displayed. If such an error
occurs, please download the latest software for your DC/DS
which, by default, has all the definitions included, or contact your
dealer for assistance. This text describes properties introduced in
receiver version 3.20.

The next page (General Settings) shows basic properties of the
receiver (picture b).
b)

The picture a) shows the following adjustable parameters:
- Serial Link – This determines the operational mode of the
receiver. You can choose from these options:
• JETIBOX & Servo – The standard mode for direct servo control.
• PPM Positive, PPM negative – the servo signal is summed into
a standard or inversed PPM signal. This option is for devices
which can use single line servo output data. Direct connection of
servos in this mode is supported as well.
• EX Bus – Tells the receiver that it should send all data onto a fast
digital serial link for further processing. This is the recommended
option if you are connecting the receiver to the Central Box or
another EX Bus intelligent device.
• UDI - Universal Data Interface. - This is a unidirectional digital
serial protocol that can transmit up to 12 channels on a single
wire. The UDI is compatible with several stabilization systems for
helicopters and airplanes.
-General Settings - redirects you to screen b)
- Fail-Safe - redirects you to screen c)
- Alternative Pin Config - redirects you to screen d)
- Receiver Outputs - redirects you to screen e)

- Output Period – Determines how often the servo signal will
be repeated to the outputs of the receiver. You can select periods
from 5ms to 30ms (in 5ms steps). Recommended option:
„Auto”.
PPM Settings
- Number of channels – if the output mode selected is either
positive or negative PPM, you can set how many channels will show
on the output.
- SAT1/SAT2 - Some types of receivers support input of backup PPM
signal. This signal can be captured via SAT1 or SAT2 ports. Here you
can define the mode of operation for the particular ports. The PPM
input can be accepted only in standard servo mode and EX Bus
mode. Additionally, the SAT2 port can be configured as a PPM
output. In this case the SAT2 outputs all 16 channels if not specified
otherwise.
61

computer radio control system

the transmitter, no driving signal for the servos (or PPM) will
be present.
- Fail-Safe Delay – The number of seconds that must elapse from the
moment of losing signal until the fail-safe is activated. This
option is available only if the Individual mode is selected.

- PPM/UDI Mode - determines processing and additional logic
applied to the PPM and UDI protocols.
- Direct - signals received from the transmitter are not further on
processed in the receiver, they are generated without any
change at the output of the receiver in form of PPM/digital
signals. If a signal loss occurs, no PPM/digital data will be generated
by the receiver.
- Computed - the signals received from the transmitter can be
processed further on in the receiver and its menus "Channel set"
and "Out Pin Set" programmable channel outputs, gains etc.)

Alarm Settings
- Low Voltage Alarm - the value serves for the setup of the alert
decision threshold. As soon as during operation the actual voltage
decreases below the set threshold, the receiver will generate an
alarm. The transmitter may announce this situation by an acoustic
tone (this depends on transmitter alarm settings, please refer to
chapter describing „Timers/Sensors -> Alarms”).
On the next page (picture c)) shows the fail-safe function
parameters.
- Fail-Safe – This parameter tells the receiver how to react when a
signal loss event occurs. If you set “Enabled" then you will be
able to set the behavior of every channel independently. The
“Disabled" option says that if no signal is being received from
62

- Each output position of the receiver has three adjustable
parameters:
• Mode (Hold, Out OFF or Fail-Safe) – Dictates, how the specific
output behaves if a signal loss occurs. Using the Hold mode, the
latest known servo position will be held. Out Off option means that
there will be no signal to the particular servo channel. The last
option, Fail-Safe, will set the servo to (user) predefined position (set
in the "Value" column).
• Value – The position of the servo after a signal loss occurs.
This is available only when the Fail-Safe mode is selected. For
convenience, you can press the „F4 Apply” button while you are
editing this column. The selected value will then appear directly
on the servo output without the need to turn off the RF modules
which would eventually activate the fail-safe and show the set
position. The “Apply” function makes it faster to set your failsafe positions.

computer radio control system

The page Receiver Outputs (picture e)) allows you to redirect your
transmitter’s channels to any output of the receiver. For convenience
the transmitter’s channel numbers are displayed together with the
appropriate function names, making it easier to adjust. In addition,
you can also set the servo group for each channel. For more
information please refer to your receiver manual.

• Slope – This slows down the speed of servo movement while the
output is moving from the normal position to the fail-safe
position.
d)

The screen d), "Alternative Pin Config", allows you to modify the
modes of receiver output pins. The servo outputs can be configured
into Digital input and Digital output modes.
- Digital input mode: a logical value of a given signal pin (0 or 1 as a
result) is transmitted to the DC/DS in form of EX telemetry so that it
can be further on processed (displayed and stored to the SD card).
The receiver pins are equipped with internal pull-up resistors. To
detect logical value of a given pin it is enough to connect the signal
pin with the ground.
- Digital output mode: The channel value of a given output pin is
discretized into two values. If the channel value is greater than
1.5ms, the pin output will be log.1. Otherwise the signal pin will stay
at logical 0. Using this way you can simply control for example lights
consisting of several LEDs. The fail-safe configuration is applied in
this mode as well as in servo mode.

8.7.1 Support of remote commands for EX Bus devices
(*depends on equipment)

The DC/DS transmitters support up to 16 universal commands for
wirelessly connected devices supporting EX Bus. To view the list of
active commands, press the „F4” CMD button when in the „Model > Device Explorer” menu. However, the command must be
detected before it can be activated. As an example of the use of
wireless commands, the Central Box can be used and its command
that resets the minimum, maximum values and battery capacity
(Clear MIN / MAX values).

computer radio control system

On the main screen of the Central Box settings scroll down to display
the maximum telemetry values (Telemetry Min/Max). Here you will
find a choice to assign a switch to the command for deleting
measured minimums and maximums (Clear Min/Max switch).
Pushing the „3D” button on this item you are moved to the list of
active commands where this command is already listed and is
inversely highlighted with a cursor.

1. The list of active commands.

2. Sa switch is assigned to reset
minimums, maximums, and the measured
capacity. For the reset command only the
Control mode is available (the position of
the control/switch is taken as an input),
other devices may accept a proportional
value specified as a constant or as the
channel number on the transmitter.

Pushing the „3D” button moves you to the choice to assign the
control/switch that will further on take care of the command for
resetting. Here we have chosen the Sa switch.
Further operation of the command will look like this:
- Moving the Sa switch into the ON position makes the transmitter
detect that it should send the command for resetting telemetry
minimums and maximums to the model. However, before the
command is applied, it is necessary to confirm the choice by the pilot
to avoid unwanted resetting of the data.

3. Scroll to view minimums and maximums.

- The transmitter displays a dialog asking if you want to execute the
command for resetting the telemetry. If you press NO or you do not
manage to respond in time, the dialog closes and the command is
not executed.
4. Pushing the „3D” button enables you to
add the command into the list of active
commands and it is possible to assign a
transmitter control to it.

- Conversely, if you press YES, the command is sent to the model
where it is processed by the Central Box which resets its telemetry.
The result of this command can be displayed on the main screen of
the transmitter in the telemetry window – the item Capacity of the
Central Box will now be set to zero.

Then you should bind the RC Switch:
• Put the bind plug into RC Switch and then turn it on.
• Push the rotary button with the "Pair RC Switch" row
highlighted on your transmitter display.
• The ID of the switch is automatically saved.
The Transmitter control switch function is a source of events:
If you want to turn the model on, then flip the assigned control
switch and confirm the question that appears. If you want to turn the
model off, just flip the switch back and also confirm the question.
You can invert polarity of the switch (if high logical level doesn’t turn
the device on) and also set the audible signals that will be activated
every time the status of RC Switch is changed (turned on or off ).

8.8 RC-Switch
The RC Switch is a special wireless device that allows you to remotely
connect or disconnect the receiver power supply of your model.
There are currently two variants of the device: RC Switch and RC
Power Switch. The difference is noticeable in the picture below. The
simple RC Switch is suitable for applications where a Central Box,
Max Bec 2D plus, SBEC 40 or other intelligent electronic device is
being used. It offers a single output pin that might be wirelessly
driven high or low according to the situation.
When connected in place of a magnetic key, the RC Switch can turn
the electronics in the model on and off.
The second variant, the RC Power Switch, can fully replace a standard
physical switch. It can directly drive servos and electronics since it
includes a couple of low-resistant MOSFETS. Just plug the RC Power
Switch between the battery and the receiver, configure the switchrelated settings in your transmitter and bind it as a standard receiver.

„F4" button in the Main Menu. Now you
need to enter the same code as when
locking the model. Confirm with „OK”
button.

1. In the main menu, push the „F4" button
to display the dialog for entering the onetime password.

Now you are asked whether you want to save the changes to the
configuration of the model or not.
Pushing „F1" NO button makes all the changes discarded and all the
data from the SD card will be reloaded.

2. Here, enter the two-digit code using the
"F1" 1/2/3, "F2" 4/5/6 and "F3" 7/8/9. This
code appears on the display and will later
be used to unlock the transmitter.

safety, eg. against the theft of the transmitter. The
transmitter is locked against configuration changes
from the moment you enter the code until the
transmitter is subsequently switched off or the code is reentered. As soon as the transmitter is switched off, (eg.
pushing the combination of POWER+ESC or removing
the power supply), the transmitter is automatically
unlocked.

1. Model selection
In the list of models, select the required model and confirm it by
pressing the „3D button“ or „F1(Ok)“ button. You will be prompted
to confirm loading of the selected model.
The DC/DS transmitters offer a „Model checking“ function, which
compares the series number of the receiver in the model profile with
the series number of the receiver with which it is starting to
communicate. If the two series numbers do not match, the
transmitter displays a warning that a different receiver has been
detected for the model. In this situation, you the user will decide
whether to:

9.1 Model

•
Confirm the change – this assigns the new receiver to the
model.

9.1.1 Model Selection

•
Reject the change – the transmitter will not communicate with
the newly detected receiver and model will not be switched on.
•
Select another model from the transmitter register.
The information about receiver discrepancies will also be displayed
after the creation of a new model and binding or establishing
communication with the receiver.
Through the use of this function, if you choose, the new receiver will
be assigned to the given model for future checks.

The menu displays a list of your models stored in the memory with
their names, setup dates and model types. The currently selected
model is marked by a check mark. In the menu you may select a
model and manage all of your models. You can copy models, delete
models (except for the currently selected model) and change the
storage sequence of your models.

9.1.2 New Model

If you would like to make set-up changes in an existing
model, you should first make a copy of the original
setup. This will help you if you would like to return to the
original model setup.

Selecting this menu item starts the new model creation assistant.
The assistant begins creating a new model profile as soon as you
select „New model“. However, the new model will only be created
after the confirmation in the last assistant menu, „Servo
Assignment“. Until you make the final confirmation, the new model
is NOT created or stored in the memory.
The setup possibilities of the DC/DS transmitters are very extensive.
For simplicity, some of the possible adjustments are accessible only
for certain combinations of wing and tail arrangements,
aerodynamic brakes, landing gears, and number of motors or
engines.

name, press the „F5(Ok)“ button to continue. Your model copy will
appear at the end of your model list.
Note:

If you would like to copy a model from one transmitter to
another you should notice that the transmitters may not
have the same software equipment, so the configuration
of activated modules may not match each other. In this
case it is necessary to check the individual functions of
the model, since an attempt to load the model file by
another transmitter may end up with an error message
(see System -> Installed Modules).

Note: For safety, start creating a model with the receiver in the model
switched off. Be careful when handling electric models or servo
binding, where an improper linkage connection may cause
damage when power is applied. When handling electric models
it is safer to remove the propeller or disconnect the motor during
model creation and tuning.

3. Deleting a Model
A model can be removed from the memory. In the model list select
the model you want to delete and press the „F5(Delete)“ button. For
safety reasons it is impossible to delete the currently selected model.
4. Choice of model sequence
The sequence of models can be changed by using the „F1()“ button
to move the selected model one position downwards or by using the
„F2()“ button to move the model one position upwards. The
transmitter allows storing of many models in the memory.
Note:

Try to arrange your most frequently used models at
the beginning of the model list in order to avoid having
to browse the whole list when selecting a model.

In this menu you will setup the wing configuration, tail type,
number of motor/engines, number of spoilers, and number of
landing gear servos. Your model’s flight control functions are
generated according to your configuration choices in this menu and
the necessary fixed mixers become accessible.

When you select the „Name“ item, the screen will change into the
„Edit“ menu, where you can use the „3D button“ to enter a name
for your model. Use the „F1()“ and „F2()“buttons to move the
cursor, if needed, within the name box.
Use the „F3(ABC)“ button to change between lower case letters and
capital letters.
Use the „F4()“ button to delete the character at the current cursor
position.
When you finished editing your model’s name, use the „F5(OK)“
button to confirm the name and return to the „New model“ menu.
The model name can be changed even after the model is stored by
going to:
„Main menu->Model->Basic configuration“ and
selecting the model name.
2.
Model type
The model type selection makes the setup of your model more
efficient by populating the menus with many of the popular options
for each type of model. The possible choices are: Aero, Heli and
General. Once your model is stored it is not possible to change that
model’s type.
Once your model’s name is entered and the type is selected, press
the „F5(Next)“ button to go to the next menu assistant step: „Basic

Swash Plate Type
Enter the type of swash plate your helicopter is using. Refer to your
helicopter’s manual if necessary.

Swash plate angle
The „Angle“ item is only accessible in the „3 servos (default 120°)“
swash plate type. The angle formed by swash plate points 1 - 2 and 1
– 3 can be configured by the user in 1° increments. This allows you to
fine tune your swash plate configuration as needed.

•
„3 servos (default 120°)“ – the swash plate controls the
elevator, aileron and collective pitch functions by coordinating three
servos. In the swash plate configuration, the servo control points can
be shifted closer to or farther away from each other around the main
shaft axis using a parameter "Lever length". In case your heli requires
a swash plate configuration of 3 servos (140°) or 3 servos (90°) you
can use the parameter angle with 1° increments.
Within this menu you can also change the effective swash plate
servo „lever lengths“ to compensate for any nonlinear servo arm
travel.

Rotation
The „Rotation“ Item is only accessible in the „3 servos (default
120°)“ and „4 servos (default 90°)“ swash plate types. This item
allows you to rotate the entire swash plate by a defined angle. This
allows you to add fine tune your swash plate as required by some
scale models.
Servo arm lengths (servo 1 – 4)
This item allows you move your swash plate control points either
closer to or farther away from the axis of rotation. This allows you to
compensate for any nonlinear servo movements.
Governor
In some helicopter setups a governor function is used for motor
control – this allows the motor to run at a constant speed
independently from any collective pitch. If your model helicopter
setup includes a governor which can be controlled through the
receiver then switch on this function. Once you enable this function,
the governor configuration becomes accessible in the „Fine Tuning
-> Governor Setting” menu.

·
„ 4 servos (90°) - the swash plate controls the elevator, roll
and collective pitch functions by coodinating four servos in 90°
orientation. You can make the same changes to this type as with the
swash plate described above.
•
„Mechanical“ - this swash plate type uses a single servo for
each flight function. This is the swash plate type to select if you are
using a flybarless controller.
Reverse swash plate orientation by 180°
The „Front servo position“ item is accessible only for the swash
plate type „3 servos (default 120°)“. If your helicopter requires, it is
possible with a single button to turn the swash plate configuration in
the setup by 180°.

Use gyro (2 - 3)
It is possible to create up to three independent functions for
controlling gyro gain. By default, gyro No. 1 is always active. The
others are activated in the „Model -> Basic Properties” menu
together with the Governor function.

Note:

Editing an item "Value" affects the diameter of the displayed circle,
ie. size of the maximum allowed deflection. The setting is global for
the whole model.

9.1.5 Swash mix

Here is where you set up the swashplate CCPM (=Cyclic/collective
pitch mixing) throws for Aileron, Elevator and Pitch. You can fine
tune each of these functions by changing their percentages. If
needed, you can reverse the throws by setting a negative
percentage.

Swash Ring
It is possible to activate the function of the cyclic limitation for a
helicopter rotor head. Activating this function causes the restriction
of servo travel in the combined full deflection of the roll and pitch
controls so that the total size of the deflection is always within the
inner area of the displayed circle. Outside the circle there is a kind of a
dead zone of the flight controls.

1. Number of Motors in the Model
This is where you select the number of motors in your model. It is
possible to select 0-4 motors. The number of transmitter control
outputs used to control the motors are automatically increased or
decreased according to number of motors that you select.
2. Motor Type
Do the motors in your model only turn in one direction or are they
able to rotate in both directions?

9.1.7 Assignment of functions

When you select one of these items, you will enter the menu: „Select
control input“, see chapter 9.7. The assignments can easily be
verified by the graphic found beside the control element description
in the „Control “ section, which shows the actual setup of the
assigned control element.
3. Choice of an Additional Trim
The transmitter allows you to also create a trim function for any
arbitrary flight function. By editing one of the „Trim“ items you can
assign an arbitrary control element (stick, switch, knob or slider) to
control the trim of the selected flight function. When you select one
of these items, you will enter the menu: „Select control input“, see
chapter 9.7. The assignments can easily be verified by the graphic
found beside the control element description in the „Trim “ section,
which shows the actual setup of the assigned control element.
The trim functions for the gimbal sticks P1-P4 are automatically
assigned to the quad push-buttons located below the gimbals.
It is not necessary to assign them manually.
4.
Range of Additional Trim
If you set up a trim function, you can use the „Trim-Max“ to set the
maximum trim influence on the given flight function. The default
value is 50%. If you set the value to 0%, the trim control element will
not have any effect on the flight function at all. If you set a value of
100%, the trim control element will control the flight function to its
full travel.
5.
Adding a Function
With the „F3(New)“ button you can create (add) your own flight
function.

Based on your selected configuration a list of all flight functions will
be created with basic transmitter channel assignments.
The menu allows you to rename flight functions, assign a flight
function to any arbitratry transmitter stick, switch, knob or slider and
also allows you to set up additional flight function trims.
You can allow the software to automatically assign your flight
functions by pressing the „F2(Auto)“ button and then press the
„F5(Yes)“ button.

1. Flight function Renaming
By editing each „Function“ item you can rename a flight function
from its original name to any name that you choose.
2. Assignment of a Control Element to a Flight Function
By editing each „Control“ item you can assign any arbitrary stick,
switch, knob or slider to a given flight function. The proportional
channels 1 – 8 are marked P1–P8. The markings Sa-Sj designate
switches with the same designation as on the transmitter front
panel.

Make sure that you have assigned all of your flight functions to the
correct transmitter control elements (stick, switch, knob or slider)
and make sure that the trims are assigned and functioning as you
wish. By pressing the „F5(Next)“ button you will enter the next
assistant step, the „Servo assignment “ menu.

1. Assignment of Transmitter Output Functions to Receiver
Channels
Select the required receiver channel and press the „3D button“.
Now you can choose which function you want assigned to the
selected receiver channel.
With the „F5(Next)“ button you will enter the next step of the
assistant which creates and stores the model into transmitter
memory.
a) The assistant asks you to confirm the creation of the model by
displaying the question „Create and select a model?“. If you answer
by pressing the „F1(No)“ button, the model will not be saved and
you will return to the assistant to continue with further
configuration of your model.
If you press the „F5(Yes)“ button, the model will be stored in the
memory and at the same time will be activated. After that, you are
automatically taken to the „Servo Setup“ menu. Your stored model
can, of course, at any time be configured by selecting the „Main
menu->Model“> „Servo Setup“ menu.

Note: The initial assignment is carried out in accordance with your
selected transmitter mode. If the initial assignment is incorrect,
check the transmitter mode setup in the „Main menu->System>Configuration- >MODE 1-4 menu.

9.1. 8 Servo Assignment
This menu shows the assignment of transmitter output functions to
the receiver channels. This assignment can be changed as you wish.
The order number at the beginning of the column shows the
channel number and the assigned transmitter output function is
next to it. In this menu you can rearrange your output functions as
needed, i. e. any transmitter function can be assigned to any of the
receiver channels. The only restriction is the number of channels
which the transmitter can control (16 channels). The transmitter can
automatically set up your servo configuration based on your
previous model setup. If you want the transmitter to automatically
assign the servos in the same order as the last model that you set up,
press the „F3(Auto)“ button and then press the „F5(Yes)“ button.

computer radio control system

3. Center (Subtrim)
With this item you can adjust the servo neutral position of the
selected receiver channel.

Advice: Once your model is created and activated, you should
bind your receiver with the transmitter and then
proceed with „Servo Setup“.

Advice: When building a model try to mechanically adjust the

neutral positions as perfectly as possible. If you are
going to use a high „Center (Subtrim)“ value in order to
set up a servo neutral, the resulting servo throw will be
restricted.

9.1.9 Servo Setup
This menu is for the additional tuning of output functions of the
transmitter->receiver channels->servos. The assignment of a
transmitter output function to a receiver channel is shown in the
upper part of the menu (first item below the menu description).

4. Max Positive/Max Negative Throw
This item sets the useable end points of the transmitter output
function, i.e. how far the transmitter control element can move each
surface. This functon is used to set your maximum control throws for
flight and to limit any potential binding of a linkage or surface. This
limit can be exceeded by the use of mixes or combined functions.
Note: The size of the maximum throw can influence trim
settings, dual rate throws and other proportional
setups.

1. Display of a Receiver Channel Throw
In the upper part of the menu the actual throw of the selected
channel is displayed using a live graphic. If you make a change to
your setup in this menu, you will immediately see how the output
will be influenced by the change.
2. Selection of Receiver Channel
In the first position F1 in the lower bar you see the actual selected
channel. With the F2() or F3()buttons or by editing the item „Servo
#“ you will select the receiver channel which you intend to
configure.

5. Max Positive/Max Negative Limit
These restrict the absolute throw of the receiver channel output.
This limit can never be exceeded by any combination of functions or
mixes.
Advice: You can adjust the throw limit to prevent a surface or

linkage from hitting a mechanical stop or to prevent the
servo from over-driving its mechanical throw range.
This allows you to prevent mechanical servo damage.

6. Servo Reversing
Use this item to reverse the direction of a servo’s travel.
7. Delay of positive/negative
This item allows you to delay the servo channel‘s travel time
between both end points. This can be defined for the positive and for
the negative value (each travel direction). For instance, the opening
of a landing gear can be slower than when it retracts.

point is located in -25%. It is then possible to move the point
upwards or downwards by turning the „3D button” to the right, or
respectively to the left. In "Auto" mode (the „F2 button” is
highlighted) simultaneous shifting of neighboring control points
occurs, so that the resulting curve is precisely smoothed. Then you
can select another control point by moving the servo control and
alter this point until the mutual mechanical stress of servos during
the movement is minimal.

Advice: This function is great for timing retract gear servos.

9.1.10 Servo balancer

(*depends on equipment)

The function of the servo balancer is designed for large models that
have control surfaces driven by mechanically linked servos. Since
each servo can be preset from the factory in a different way and
mounting servos into the model is not always accurate, it is now
possible to set servo travel algorithmically to ensure minimum
mechanical stress during the movement of the controls.
Thus it is possible to assign a separate curve to each output channel,
which is applied as the last operation before sending the deflections
to the model. Because it is applied last, the curve is ultimately
applied to trims, mixes, dual rates, etc., so that servos of the same
control surface always move together equally. The Servo balancer
can alter the curve of the servo by a maximum of ±10% with a
resolution of 0.1%.

2. After pushing the „F1 button”
when the servo balancer is
highlighted, the speed dial is
displayed. Here is where you can
select one telemetry parameter,
which will appear at location of the
digital clock on the top bar of the
screen. This way you can select eg.
displaying the instant current draw
from the batteries, which is very
helpful when balancing different
servo travels.

1. After you highlight the graph of the servo balancer, push the „3D
button”. This enables editing of the servo curve. Now, always one
control point is highlighted according to current servo deflection. If
the current servo position is -30%, the nearest highlighted control

computer radio control system
Note:

Advice:

Setting the display of the
telemetry data on the top
menu bar of the screen is saved
as a part of the model
configuration and it is
displayed again when the
transmitter is switched on.
Alternatively, it is possible to
adjust the displayed data in the
„Timers/S ensors -> Ma in
Screen” menu. It is possible to
select any simple numerical
value, except GPS coordinates.

3. The „F2 Auto” button enables switching between automatic and
manual selection of control points in the servo balancer edit mode.
When selecting control points manually, push the „3D button” to
move to the next point; pushing the „ESC” button activates the
previous check point. When editing in the manual mode, you move
(as opposed to the automatic mode) only one control point, the
others remain unchanged.
If the „F3 Clear” button is pushed for a short time, it quickly clears a
control point (which must be highlighted). If the „F3 Clear” button is
pushed and held for longer time, the whole curve is cleared to a
default state.

EN
If you use several mechanically
linked servos to control a single
wing surface in the model as
shown in this example, we
recommend setting all the
ser vos b elonging to this
surface into one output group
(Group A-C). In the picture this
is done via the Device Explorer
application. In this way the
servos will receive control
pulses at the same time and
their movement will thus be
synchronous.

Advice: To optimize the servo travels via servo balancer, we

recommend that you use an ampermeter (or eg. the
current measurement from the MUI sensor displayed in
the telemetry window) and always try to make sure that
the current running through servos as low as possible.

computer radio control system

Up to 10 different flight modes (depends on activated transmitter
equipment) are available for every single model. Each one of these
flight modes can be named differently for instant recognition. Only
one of the flight modes can be active at any given time. With a little
practice you will discover that creating your flight modes in logical
order can prevent confusion in a critical situation. Flight mode
control can be assigned to any of the switches, sticks, or knobs of the
transmitter.

• Also, if the flight mode configuration is set to S, different
variables for each function can be assigned to each flight mode. The
assigned control switch can control multiple values within each
flight mode.

The purpose of programming Flight Modes is to provide the ability
to activate a group of settings that will optimize your flight control of
your model. Flight Modes can just as easily represent settings for
Take Off, Soaring, Landing and much more. They can be used in any
particular situation where different settings of basic flight
parameters is desirable. The DC/DS gives you the advantage of a
wide variety of programing options.

• After creating a flight mode, this will become system wide
settings for all future models.

2. Naming Flight Modes

Advice: If no flight mode is required, do not change the pre-set

configuration.

We recommend naming flight modes according to their function, for
example: Take Off, Soaring, Autorotation….
Flight mode names/labels can be easily edited at any time.
3. Flight Mode Delays

The time delay function can help smooth the transition from one
flight control state to another. Sudden changes in the positions of
your control surfaces can negatively affect performance or even
create a critical situation. The Time delay can help you avoid this
situation.

function will always be performed instantly.

4. Flight Mode Activation
A flight mode can be activated by any control device
(Switch/Knob/Stick). When you select a switch and by editing its
desired assignment you can activate and pick the position at which
this Switch/Knob/Stick or Logical Switch will turn flight mode ON or

10. Flight mode announcement after flipping a switch
the trim value after shutdown. After pressing the trim button no
superior functions are trimmed, only internal state of trim is
incremented.
- Trim.RstOn (trim control with automatic reset) – enables using
the specific trim independently from model functions. The
transmitter does not remember the value of trim after shutdown.
After loading the model, the trim value is always 0%. In combination
with the logical switches this option is suitable for a sequential
switching between flight modes or playing sound sequences.

It is possible to assign an arbitrary switch to the flight mode voice
announcement. After switching on, the actual flight mode will be
announced (the selected WAV file will be played back).

9.2.2 Digital trim
Fully programmable digital trims are located right under the
transmitter gimbals as a set of four directional buttons. All
adjustments and step changes are made in the “Digital Trim” menu.
You can assign different trim ranges and trim steps to every trim
control function.
The trim dialogue has been divided into two screens, a) and b). You
can switch between each of them by using the "F1 Left" and "F2
Right" buttons. The “F3 (Trim)” button switches your desktop
display to the main trim screen where you can instantly observe
your setup changes.
As you can see from the screen a), you can assign any function that
will be influenced by that particular trim. It is also possible to
deactivate the trim so that it doesn’t influence any function (simply
unselect the assigned function). This is mostly important for pilots of
various multicopters or helicopters equipped with advanced
stabilization electronics.
Special trim functions
Digital trims can be used independently as controls for any function.
It is possible to assign the special functions "Trim.Ctrl" or
"Trim.RstOn" (Trim – Automatic reset) to any digital trim.
- Trim.Ctrl (Trim control) – enables using a specific trim
independently from model functions. The transmitter remembers

The operational modes of the trims have also been extended (see
picture c)). There are currently these options:
Global – the specified trim will have equal settings for all flight
modes.
Separate – every flight mode has its own independent
configuration of the trim.

computer radio control system

3. Mode – here you can specify a basic behavior of the trim:
• Centered mode – by default, the trim affects only the servo
center, the endpoints remain untouched.
• Linear – shifts the whole servo travel, including endpoints.
• Thro-Low – affects the servo low endpoint and the entire
curve, except for the high endpoint.
• Thr-L50% – affects the servo low endpoint and curve below
50%. This does not affect the curve above 50%.
• Thro-High – affects the servo high endpoint and the entire
curve, except for the low endpoint.
4. Step – indicates, how much the value of trim changes each time
the trim button is pressed.
5. Rate (+,-) – determines maximum limits used for the trim.

Advice: For the maiden flight we recommend using larger trim

steps. After familiarizing yourself with your model’s
behavior you can switch to smaller steps for finer
trimming.
Flight-Mode Group (A/B) – if you are using several flight modes and
you want to share trim settings among a few of them just
set one of the groups FA or FB for the particular trim. Each
group has its own settings which are then shared. Note: If
you change from Global to any Flight-Mode Group, the trim
mode in other flight modes than the current one will
become Separate.
Note: If you change a flight mode from Global to either of the
Flight-Mode groups the trim mode for the rest of the
flight modes (except for the one you are currently
editing) will change to Separate.

The rest of the parameters are described below:
1. Value – shows the actual trim rate.
2. Stored – shows the stored value of trim memory function.

In the picture below you can see how various trim modes influence
the servo output (trimmed to ca 50% of range). However, you
cannot use any trim mode at any time:
V-Tail configuration - You can specify the trim mode only for the
elevator function, not for rudder since these functions are linked
together.
Delta/Elevon configuration - You can specify the mode only for
ailerons, not for elevator.
Helicopter using CCPM mix - You can specify the mode only for
pitch function, not for elevator nor roll function.
If you use two or more trims to adjust a single function, the resulting
trim rate equals to a sum of all rates that are participating on this
function. However, the transmitter uses always only a mode defined
for the first trim.

computer radio control system

Warning: The Autotrim feature, when active, always influences the
model functions currently assigned to the particular trim
buttons (except for throttle function which is never affected by
this feature). The Autotrim function does not take effect on the
auxiliary incremental trims. Please be very careful if you
assign trim buttons to any function that is not controlled by a
spring centered stick. It is advised to disable the Autotrim
completely in such a case.

Press the "F4 button" to display additional trim options. See picture
d). You can store the currently highlighted trim (for example Ailerons
in the picture) to trim memory, or you can apply the trim memory
function to all trims.
How it works: The actual rate of the highlighted trim (or all trims,
respectively) is copied into a special register. (See the last colum of
picture a)). Once the rate is stored, the trim rate column value will be
cleared. This applies always to all flight modes. The trim memory
function is beneficial if you want your trims zeroed although some
offsets have been set. When processing, the transmitter sums the
actual trim rate and its stored value.

This menu allows you to set the function output position (if needed)
for each flight mode individually. For example: if your elevator
needs to be raised in one of your flight modes but not the others.
Each function output can be set either globally or separately.

Pressing the “F1 (Sym.)” turns ON/OFF the lock which allows each
output to be adjusted either together (symmetrically), or
independantly.

9.2.3 Flight Mode Trims

1. Servo Position
A transmitter output channel can be assigned to more than one
receiver output channel if needed. Adjusting the values in the
individual columns marked “S1-S4” will change the position of the
servo (surface) for each output function. The servo position is
displayed as a percentage of the total servo travel.
Pressing the “F3 (Clr)” button resets the highlighted line’s travel
values to 0%.

In the picture d), there are two more options available: Clear highlighted trim and Clear all
trims. After confirmation, this option clears the actual trim value (or all trim values,
respectively) and similarly zeroes the previously stored values (trim memory). This always
applies to all flight modes.

computer radio control system
2. Trim Travel Global or Separate Setting
The servo trim position for each function output can be set either
collectively for all flight modes by selecting the “G-(globe symbol)”
or individually for each separate flight mode by selecting “SSeparate”.

9.2.4 Dual Rate/Exponential
This menu allows you to set up dual or triple rates for any of your
created output functions. Any of the channels can be set with
dual/triple rates and custom exponential settings. Exponential
settings can significantly increase your control precision by making
your stick movements (around center point) yield less control
movement. At the same time, the end points of the control surface
throw can be set to its extremes.

3. Expo/Dual Rates Travel Setting
Every switch position (b) can define a different function and
exponential value. Any change made to the settings can be directly
observed on graphic interface (f).
Dual/Triple rate setting is defined by percentage of the travel (c). A
higher number increases travel, a lower number decreases travel.
Expo rate is defined by percentage of the function curve (d). Zero
rate represents linear function. As expo rate increases linear travel
changes to exponential “curve” travel.
Exponential and Dual rate settings combined with flight modes
create virtually unlimited customizability.

2. Expo/Dual Rates Switch Assignment
By selecting “Switch Option” (e) you will access the“Select Input
Control” screen where you can select the control element that you
wish to control the dual rate and/or expo for the selected function.
For simple dual rates, a 2-position switch is sufficient. For more
complex triple-rates, any 3-position switch or one of the fully
proportional channels can be selected. Then your selected switch is
assigned. While the “Select Input Control” screen is still visible you
can change the switch travel by using “F2 (Prop.)” button to select
the proportional setting. The correct function can be verified in the
“Dual Rate Edit” screen by activating the switch and observing the
position number change to “Position 1-2” for a two position switch
or, if 3-position switch is used, to “Position 1-2-3”. For a 3-position
switch you will also need to use the „F1 (Centr)“ button before all
three positions are correctly displayed.

3. Function Curve Delay
The time delay function can help smooth the transition from one
state to another. The function of the “Delay” is to slow down the
movement of a control surface in relationship to the position of the
stick. Example: a negative number “-” slows movement of the
rudder from moving right to left, a positive “+” number slows rudder
movement from left to right.

2. Function Curve Setting
You can select the function curve which best fits your application.
You can choose one of the pre-programmed 3-9 point ones or select
any of custom symmetrical curves.
You can edit a function curve from inside the graphic interface by
moving the displayed control points.

2. Aileron Differential Setting
All of the ailerons can have different travel ranges. The different
adjustments are displayed in columns marked „S1-S4”. The number
of servos in use is equal to the number of displayed setup columns.
The travel range for each servo can be set. Scroll and highlight either
the “Up” or “Down” menu line with “3D Control” button. Press the
„3D Control“ button to access and edit the settings for each servo. If
the servos need to be adjusted independantly, use the “F1 (Sym.)”
button to unlock the servo travel for adjusting the individual values
in the selected menu line.
3. Tuning of Aileron Differential
You can now assign a proportional control and the adjustment rate.
When moving the control, the differential rates are updated
accordingly: up-rate is increased and the down-rate is decreased
depending on the adjustment rate and position of the control. In the
picture the real differential rates are enclosed in parenthesis.
The „F(3) Apply” button clears the adjustment rate and stores the
real differential values into the editable fields so that the control no
longer has any influence.

4. Global or Separate Function Curve Setting
The function curve configuration for all channels can be set
collectively for all flight modes by selecting the “G-Global (globe)”
symbol or you can set individual function curve settings in each
separate flight mode by sellecting the “S-Separate” symbol.

9.2.6 Aileron Differential
The aileron differential function reduces the downward travel of the
aileron(s) to help eleminate any adverse yaw tendencies in rolling
maneuvers. Semi-Symmetrical airfoils with an aileron in the down
position induce higher drag than when the aileron is in the up
position. Therefore, the aileron travel up and down has to be set
differently. The number of aileron servos displayed depends upon
the selected wing type of your airplane; the maximum number is
four “S1-S4”.

9.2.7 Ailevator Function
The ailevator function uses two servos for the elevator channel. Both
sides can be programmed to be controlled independently. With
ailevator function both servos can be mixed together with ailerons
and work in sync for better roll control. The Ailevator mix has to be
activated by choosing the “Ailevator2H1V” tail setting. Unless you
have previously chosen a different percentage for one of the tail
mixes, the initial settings for “Ailevator” function are 100% of the
elevator travel and 0% of the aileron travel.

1. Aileron Differential Global or Separate Setting
The aileron differential for all channels can be set collectively for all
flight modes by selecting the “G-Global (globe)” symbol or you can
allow individual aileron differential settings in each separate flight
mode by sellecting the “S-Separate” symbol.

“F1 (Sym.)” button to unlock the servo travel for adjusting the
individual values in the selected menu line.

The Delta/Elevon Mix uses two servos for the control of both the
elevator and aileron functions. This mix is most commonly used for
Delta type aircraft. The elevon mix has to be activated by choosing
the “None – Elevon/Delta” tail setting. Unless you have previously
chosen a different percentage for one of the tail mixes, the default
settings for the “Delta/Elevon” function are 50% of the aileron and
elevator travels.

9.2.10 Butterfly Mix (Crow Mix)
The basic configuration of the butterfly mix (also known as crow) is
created by using ailerons, flaps, and elevator flying surfaces. The
Butterfly/Crow mix is helpful for maintaining speed during fast
descends and creating controlled drag for spot landings.

1. Delta/Elevon Global or Separate Setting
The Delta/Elevon configuration for both channels can be set
collectively for all flight modes by selecting the “G (globe)” symbol
or you can set individual Delta/Elevon settings in each separate
flight mode by sellecting the “S-Separate” symbol.
2. Delta/Elevon Setting
Delta/Elevon configuration has four different adjustable

mode by sellecting the “S-Separate” symbol.

b. Ailerons/Flaps Adjustment
In the Ailerons/Flaps Adjustment menu you can set all the travel
needed for butterfly braking (for the flaps and ailerons). Also, you
can set a parameter called Diff. adjust which influences the aileron
differential. Positive values increase the upper travel of the aileron
servos, negative values increase the lower travel of the aileron
servos.

4. Butterfly/Offset
Due to the request of many sailplane pilots this function was
updated. Now expanded to four screens, there are several added
options in this menu.
a. You can set an offset to the butterfly control so that there will be
a specified dead zone at the beginning of the control stick’s travel.

c. Elevator compensation
The butterfly mixing is always from zero to the full stick position so
the curve is a little bit modified to control the whole travel range. You
can choose between a standard curve, constant and X-point curve
types.

9.2.11 Free Mixes (*depends on equipment)
The Free (programmable) mixes are used to make a second or „slave“
channel react as a result of the original channel’s input or by moving
any Switch, Knob or Stick. Any of the channels can be (Freely) mixed
with any other function, assignment or logical switch. Up to 20 free
mixes can be programmed for any given model. The primary
channel (“Master/From”) specifies the control or input function,
while the channel that reacts to the Master is called the “Slave/To”
channel. The “Master Value” represents the percentage of „slave“
channel travel output performed when the „Master“ channel
function is used.

d. Butterfly Tuning menu
Screen of the Butterfly menu allows you to fine tune all braking
travels through one proportional control (stick, knob or switch). The
values you set in this screen are added/subtracted to the
appropriate butterfly travels. The way these values influence servo
deflections depends on the position of the butterfly's control stick
and the position of the butterfly's Tuning control.

The „F3Apply” button operates similarly as in the Aileron
Differential menu. If you press this button, the values set in the
„Butterfly Tuning” menu are copied into the appropriate travels in
the „Butterfly Ailerons/Flaps/Elevator Adjustment” menu. After
that, all values in the Butterfly Tuning menu are initially set to zero (so
that the tuning control no longer has an effect).

1. Copying a Free Mix
Highlight an existing free mix and use the “F1 (Copy)” button to
create a copy of the existing mix.
2. Creating a Free Mix
Use the “F2 (Add)” button to create a new free mix. The Primary
channel called “Master/From” specifies the input function, while
the channel that reacts to the Master is called the “Slave/To”
channel. The last variable on the screen is the “Master Value” which
represents the percentage of the slave channel’s mix/travel. After
your model‘s basic configuration is finished, use the “F5 (Next)”

a). Free Mix Setting
The free mix configuration settings can be set collectively for all
flight modes by selecting the “G-(globe)” symbol or you can allow
individual free mix settings in each separate flight mode by
sellecting the “S-Separate” symbol.
b) Free Mix Activation
A free mix can be activated by any Switch/Knob/Stick. By selecting
“Switch” and by editing the desired assignment you can activate
and choose the position at which this Switch/Knob/Stick or Logical
Switch will turn the mix ON or OFF or even control its throw
proportionally. This menu line includes a visual graphic to show the
ON or OFF position of your selected switch. If you do not select any
switch, then the mix is always ON.
c) Free Mix Curve Programming
This programming screen can be accessed by highlighting the
“Curve” item and by either using the “3D Control” button or by
pressing the “F4 (Curve)” button. By accessing the “Mixer Curve”
function screen you can select the mix curve which best fits your
application.

d) Free Mix Deployment Delay
The time delay function can help smooth the transition from one
state to another. Values adjusted in the “Source” item will slow
down full mix deployment when the mix is ON (switched ON or
always ON) and the master channel changes its value. In this item,
when you add a delay to only one side (- or +), the mix deployment
will be slow in one direction only (-100% to 100%) or (100% to 100%). When you add a delay to both the negative (-) and the
positive (+) sides, then your mix will be slowed in both throw
directions.
e) Free Mix Activation/Deactivation Delay
The „Switch“ values can only be when you have assigned a switch to
turn the mix ON and OFF. This delay operates independently from
the „Source“ values. The positive side of a delay is applied if the mix
is activated using Activation Switch. The negative side is used if the
mix is deactivated and both slow down any fast reactions while
turning the mix ON and OFF.

(Servo)” button. Pressing the “F5 (Ok)” button returns you back to
free mix screen.
k) Aileron Differential
This option is displayed only after you create a mix from any function
to Ailerons. When this option is activated, the output of the mix will
be influenced by the aileron differential settings. If this option is
deactivated, the output of the mix is transmitted directly to the servo
without any modifications. Uncheck this option if you want to use
aileron differential fine tuning without affecting throws of the mixes
applied on ailerons.

f) Free Mix Multiple Servo Settings
If the mix uses more than one output function as the slave, then the
“Output Mix” menu will appear. This menu allows you to edit the
settings for the individual slave servos (S1-S4).
g) Free Mix Directional Positive/Negative Movements
Once the free mix function is created you can edit the advanced
settings menu so that the mix will either add to or reduce a slave
function‘s movement. To do this, you can set the mix value as a
positive percentage or a negative percentage.
h) Using Another Free Mix to control a Free Mix
A free mix can be controlled by just a control input function (Master)
or it can also be controlled by another free mix’s control function
(Slave). Here is how to create a free mix whose input is controlled by
an existing free mixer output:

• To allow a free mix to control another free mix you must enable
the “Slave Link” option. This allows the free mix to act as input for
other free mixes. Use the “3D button” to highlight and select this
option. You will see a check mark if the option is enabled and an X if it
is disabled. You will also use the (+) or (-) to determine the mix
direction.

In the Gyro settings menu it is possible to edit up to three main
values for each gyro function in all flight modes separately according
to the position of the main control/switch.
Moving the switch to the selected position causes an automatic
update of the depicted values in the appropriate line. Set the main
value of the gyro gain to the needed value (highlighted in the
picture), eventually also assign an appropriate control for fine tuning
– here it is necessary to set also the percentage range of the control
influence. For each position of the main control it is possible to
individually assign an independent control for fine tuning of the
gyro gain. The resulting applied gain value is displayed in
parentheses (-50% in this case).

9.2.12 Governor/Gyro (*depends on equipment)
Typically, a gyro is used to stablize a model helicopter along its
vertical axis (rudder). One channel is reserved so that you may adjust
the gyro sensitivity (gain) from the transmitter. Also, a separate
channel can be reserved for the control of a throttle governor. The
governor can be enabled when you create the model or later from
the „Model >Basic Properties“ menu. This menu allows you to
adjust the settings for both of these output channels. The
Governor/Gyro settings can be set collectively for all flight modes by
selecting the “G-(globe)” symbol or you can allow individual
Governor/Gyro settings in each separate flight mode by sellecting
the “S-Separate” symbol.

Note:

Negative values of gyro gain indicate the gain in
"Normal" mode, positive values indicate the gain in the
"Heading-lock" mode.

2. Governor Settings

1. Gyro Settings
By default, the gyro sensitivity is assigned to the three position „Si“
switch. This allows you to have three different settings (Position 1,
Position 2, Position 3) for the gyro sensitivity. You can always assign
this function to a different transmitter control element (knob, slider,
switch) in the „Model, >Function Assignment“ menu. The Gyro
settings can be set collectively for all flight modes by selecting the
“G-(globe)” symbol or you can allow individual Gyro settings in
each separate flight mode by sellecting the “S-Separate” symbol.

If you have the governor function enabled, by default, the governor
sensitivity is assigned to the three position „Sg“ switch. This allows
97

computer radio control system
you to have three different settings (Position 1, Position 2, Position 3)
for the governor sensitivity. You can always assign this function to a
different transmitter control element (knob, slider, switch) in the
„Model, >Function Assignment“ menu. The governor settings can
be set collectively for all flight modes by selecting the “G-(globe)”
symbol or you can allow individual governor settings in each
separate flight mode by sellecting the “S-Separate” symbol.
Like in Gyro gain settings, it is also possible to select up to three main
values for governor RPM control in the Governor settings menu (0%
means zero RPM, 100% means full throttle). It is also possible to
assign a specific control to each governor position (switch, stick or
knob), which can precisely tune required RPM – in this case it is
necessary also to specify the range of the influence of the tuning
control to the RPM. The resulting applied value of the Governor
function is displayed in the parentheses. The setting can be global
for all flight modes or separate for each mode.

operates within a specified range (negative and positive rate, “- Rate
+”). Using the “-” rate you can set the lowest motor RPM you want to
use. This is the point where the limiter begins its operation. The “+”
rate represents the maximum possible output of your throttle
channel. If your application needs full throttle, you should set the
“+” rate to a value higher than 100% so that the full throttle output is
not limited.
It is possible to set some delay for this control (if it is assigned to a
switch) so that the motor goes smoothly from low to high RPM (and
vice versa). Finally, the Exponential parameter enables you to finetune the output at lower RPM and the whole acceleration curve.
The throttle limiter also influences mixes where the throttle acts as
the source. The trim function is not influenced by the throttle limiter.
If a control device is not assigned, the throttle limiter function is
disabled.

9.2.13 Throttle Limiter (* depending on equipment)
If you have several flight modes and all of them have specific throttle
curves, the Throttle Limiter might help you to get the motor's RPM
safely from the lowest to the maximum RPM that is controlled by
your throttle curve.
You are free to choose any control device (proportional or a switch)
that will operate as a speed limiter. It doesn't allow the throttle to go
any higher than the position that this control shows. The limiter

You may enter your desired properties for ailerons, elevator and
rudder separately for every direction. There are four directions
available (up/right, down/right, up/left and down/left), each one is
controlled by a separate direction switch. Each element may store its
own fade-in/fade-out ramp which is defined by the rows “Delay +”
and “Delay -”.
All options may be either flight-mode-specific or global. You can see
the current state of the snap roll function in the bottom left corner of
the display.

1. Auto-Trim Function
Auto-Trim function can be activated using any assigned switch,
knob or stick. Once this function has been activated you can trim
your model using transmitter gimbals. The direction and speed of
the trim adjustment is determined by stick movement. Larger stick
movements equal a faster trim response. When the Auto-Trim
function is active, the transmitter gimbals do not change their
standard response. The transmitter is still in normal operation mode.

9.3 Advanced Properties

2. Trainer Function
The Trainer function can be set so that it may be activated using any
assigned switch, knob or stick.
3. Telemetry Recording
The Telemetry recording function can be set so that it may be
activated using any assigned switch, knob or stick. The data stream is
recorded on the internal SD memory card. All data can be found in
the “Log” directory of the transmitter software after connecting the
Tx to the PC via a USB port. Active data recording is indicated on the
upper edge of the main desktop screen by a blinking circle. A solid
square graphic indicates that recording is stopped.
3a. Mode
By default ("Auto" mode), the telemetry starts recording after any
timer is activated, Start-logging switch is flipped or Start button on
the main screen is pressed. If the "Start/Stop" mode is selected, the
status of recording is always controlled by the position of your
selected Start-logging switch.

The first menu line item lists the control’s number and the second
item lists the type of control element. Using the “F2” and “F3”
function buttons you can scroll through channels, with the “F5 (Ok)”
button you can exit the menu screen.
By default, the switch types are always automatically detected,
however, it is also possible to overwrite any of the auto-detected
switch types with a user-defined type. The choices are: "Auto" which
keeps the auto-detection running, "None" that disables the
particular input control, standard "Std. Switch", "3-Pos. Switch",
"Button" and "Proportional". Any value other than Auto will disable
auto-detection for the specified control. Remember, these settings
are global and are applied to all models. The only model-specific
"Type of control" property applies to stick-switches Sk and Sl. This
feature is useful, for example, if you want to have a standard switch
that behaves like a spring loaded switch equipped with button
memory.
2. Switch ON/OFF Points
Any proportional function can be set as a system switch. This menu
item enables you to assign the travel percentage at which a desired
function can be turned ON or OFF.
“Switch-ON” – The point when the control element positon will
switch a function ON.
“Switch-OFF” – The point when the control element positon will
switch a function OFF.
By default, the system setting for all proportional channels and for all
inputs is set to function the same as a 3-position switch.
a) A function above this point is considered to be “Switch ON”

4. Throttle Cut Setting
This safety feature is mainly for models using glow or gasoline
engines as their main source of power. Electric models can also
highly benefit from this safety feature. The Throttle Cut function can
be activated using any assigned switch, knob or stick. By editing the
“Output Value” item, the throttle output will move to the user
defined (completely off) throttle position once the assigned switch
is activated.
5. Throttle Idle Setting
This feature is used to set the idle position for your throttle and will
prevent your engine from shutting-off when you move throttle stick
to its low position. The minimum throttle setting is defined by
editing the “Idle Offset” value. When this function has been
activated, the minimum throttle setting (idle point) is defined by the
offset value as a percentage. Standard throttle function is not
affected by the idle offset setting.

9.3.2 Sticks / Switches Setup

“Switch ON” or “Switch OFF”
c) A Function below this point is considered to be“Switch OFF”
If the switch setting is set at same level for “Switch ON” and “Switch
OFF”, the proportional channel/function output will be the same as
a 2-position switch.
3. Required Preflight Position
For any functions assigned to the Switch, Knob or Stick, any preflight
initial position can be programmed. If the pre-programed Switches,
Knobs or Sticks are not in required preflight position while model is
being activated, system will refuse to switch to this model. The
transmitter screen will display the function that is not in preprogrammed, correct preflight position.
4. Function Status Display
Position and status of the control is displayed in the status bar. On
the right side of this menu you can see the status of the switch
function as an “x” or check mark.
1) Setting Example
If you have installed the optional a button/switch in your left or right
stick, scroll thru the Control No. Menu line and pick the function
switch “Sk” or “Sl” if the button switch is installed in your right stick.
Pick one of the “Type of Control” switch options:
• “2-Position Switch”
• “3-Position Switch”
• “Button”

The transmitter RF modules can operate in one of three modes. For a
detailed explanation. (see section 5) The wireless RF setting is
programmed to the memory of individual models (receivers). While
programming a selected model you will need to configure the RF
module settings. The only exception for the system is the “Trainer”
mode. If the particular model has been programmed in Trainer
mode, this setting will not change if the Tx is turned ON or OFF.
For safety reasons, the “Trainer” RF mode will be switched
automatically to “Initial” RF mode when a different model is
selected in the transmitter.
DS/DC radio systems are excellent tools for instructor pilots. Basic
training for a student is not different from flying his own model.
Both the instructor and student have their own JETI transmitters, all
communication between the transmitters is done wirelessly. The
instructor decides when to give control of the model to the student
and when it’s time to step in. The instructor’s primary transmitter RF
module communicates with model and the secondary RF module
communicates with student’s transmitter. The Student’s transmitter,
if set to “Student” mode, disables its secondary RF module and uses
only the primary RF module to communicate with instructor’s
transmitter.

For any functions assigned to the chosen switch, knob or stick, any
preflight initial position can be programmed.

f)

Assignment for the input channel from the student’s
transmitter to the Control function of the instructor’s
transmitter.
The Trainer Mode allows you to directly assign an arbitrary
control (switch, stick, even a logical switch) which will be
emulated for further use in the student's or teacher's
transmitter. The list of emulated inputs is located at the bottom
of the Function list. The behaviour depends on the mode
setting of transmitter:
1) Student mode. Here you can simply assign an arbitrary
control which will directly output its position/value to a
defined channel of the student's transmitter. In the picture,
the proportional control P8 is assigned to the seventh
channel. You can disable the output by un-checking the
"Enabled" button.
2) Teacher mode. Here you can decide which controls will
be emulated by any of the student's channels. At the
moment the student takes control of the model, the values
of these controls are fully overwritten by the values of the
appropriate student's channel. In the picture you can see
that channel seven emulates the proportional control P8
and thus all functions that rely on this control knob. With
this option, the student may switch the flight modes,
operate the Butterfly function directly etc.

Caution: If you disable the transmission with a model attached,
you may cause a signal loss alarm.

Signal Loss Alarm Settings
It is possible to define a specific response from the transmitter after
one or more receivers disconnect or lose signal. The options are:
• Loss of any receiver – the alarm is activated every time any of the
receivers loses a connection. This mode is sufficient for applications
where two receivers control separate functions of the model. Both
receivers must be connected for proper function.
• Loss of receiver Rx1 – an alarm is triggered only if the primary Rx
loses connection. This mode is intended for competition pilots who
use the primary Rx in the model while the second receiver is acting as
a reference for the judges. In this mode, the receivers are
independent and you can control your model with only one receiver
connected.
• Loss of receiver Rx2 – an alarm is triggered only if the secondary Rx
loses connection. The intended use and behaviour of this mode is
similar to the previous mode.
• Loss of both receivers – an alarm is triggered after the signal from
both receivers is lost. You should use this option if you want to join
servo signals redundantly using the Enlink plug or any other central
control unit. Both receivers must be connected for proper function.

Pairing the transmitter with receivers in Double Path mode
1. Make sure that receivers are set in Normal mode, not in Clone
mode.
2. Note down which receiver is the first and which is the second
because of later easier identification. Keep the receivers switched
off.
3. Switch on the transmitter with created model, in „Advanced
properties - Wireless modes/Trainer” menu item select „Double
Path mode”.
4. Plug the BIND PLUG interconnection into EXT output of the first
receiver. Switch on the receiver. Now the receiver expects a
sequence for pairing (in case you have Rx firmware version 3.11 and
newer, this period is limited up to 60s).
5. Press „3D pushbutton” on the transmitter over "Pair primary TX
module" command. As soon as the receiver is identified, you will be
asked for confirmation – now push OK button. Switch off the receiver
and remove pairing interconnection.
6. Plug the BIND PLUG interconnection into EXT output of the
second receiver. Switch on the receiver.
7. Press „3D pushbutton” on the transmitter over "Pair secondary
TX module" command. As soon as the receiver is identified, you will
be asked for confirmation – now push OK button. Switch off the
receiver and remove pairing interconnection.
8. Switch on both receivers. The connection should be established
immediately, eventually servo control is allowed.
9. Now you can specify additional parameters of the Double Path
mode so that the transmitter correctly responds to the signal loss
from any of the receivers.

computer radio control system

9.3.4 Logical Switches (* depending on equipment)
If you want to have single or multiple transmitter functions which are
controlled based upon the condition of other control conditions,
then setting up a logical switch is the way to go. Each logical switch is
defined by a logical expression. The logical expression contains a
logical function and the relationship of the other conditions which
must exist for the logical function to be activated. The end result is
that your logical switch can either work like a 2-positon switch
(ON/OFF) or like a proportional 3-position switch (ON/Center/OFF).

2. Logical Switch Proportion Calculation
Logical rules can also be created when your logical switch uses
proportional channels. To enable proportional evaluation press the
„F2(Prop)“ button when you select your input controls. When you
allow the use of proportional controls, an additional condition menu
will appear. In this menu the conditions can be set by percentage
value of the channel as well as by the value from which the switch
will be in its full ON/OFF position. Those conditions will then be used
to calculate the logical result.

1. Creating a Logical Switch
Up to 16 independent logical switches can be created. Select one of
the numbered lines and press the „3D button“ to access the logic
switch setup menu. To enable the switch highlight and change the
enabled value to “Yes”. Once activated you can see the control
inputs and conditions on the menu screen. First set the control
inputs #1 and #2 by assigning functions to switches, sticks or knobs.
After that, select your desired logic statement (OR, YES, Multi). On
the bottom of the screen the result of your logical expression is
displayed by either a check mark or an „X“, depending upon the
current conditon state.

Example: This figure shows the use of proportional processing by a logical switch. In this
example, if the P2 stick is moved between 20% and 80% of its travel, the logical switch is in the
ON position. If the P2 stick is moved from 0% to 20% or from 80% to 100% then, the logical
switch is in the OFF position. All 16 logical switches can be configured this way if needed.
(number of available logical switches depends on actual transmitter equipment)

107

computer radio control system
3. Emulating a 3-Position Switch
You can use the logic function “Multi” to allow the logic switch to act
as a 3-position switch. The “Multi” logic function can combine the
output from two 2-position switches to create a logic switch with
three output conditions.

4. Using Proportional Logical Switches
The logical switches also offer the option of a complete proportional
evaluation that could be applied to both controls. Just select an
input stick/slider, press the F2 “Prop.” button in the same menu
(picture e)) and confirm. Then edit the selection box with options
“X<”, “X>”, “Lin” and make sure that you select the “Lin” option
(picture c)). At this point, the logical switch starts to act as a
proportional control.
108

computer radio control system
9.3.5 Sounds on Event (Sound Assignments)

•
The AND condition: The resulting value of the switch is
calculated as minimum value from both controls. If you have two
sliders, the first one has +25% and the second one has -25%, the
result returned by the logical switch will then be -25% (picture c)).
•
The OR Condition: The resulting value of the logical switch is
calculated as maximum value from both controls. The higher value
will be returned (picture d) ).
•
The Multi condition: This option still emulates a 3-position
switch. The output values of the logical switch are then in range 100%, 0% and 100% (picture b) ).

(* depending on equipment)

You can assign an audio file to be played based on any transmitter
condition. This means that any music file stored in the transmitter
can be assigned to any switch, stick, knob, logical switch, alarm or
any other special function. Since you can also upload music files the
the DC/DS, you can fully customize how your transmitter
communicates with you. If multiple sound files are triggered at the
same time, they will play at the same time and their sounds will
overlay each other.

Example: How to enable or disable the Butterfly function using
a switch.
Many people want to have the ability to turn the Butterfly function
on and off independently from any flight mode. So here we show the
way to do that (see picture c) ).
1. Select an arbitrary switch as Control 1. In the picture, Sj was
chosen. This switch will overwrite the function of Control 2.
2. As a Control 2 select a proportional unit that will operate the
Butterfly function (P2 in this example). Make sure it is evaluated
proportionally (see picture e) ).
3. Control 1 and Control 2 are linked together using AND logical
function. That means, if the switch Sj is deactivated, the operation of
P2 will be blocked. Otherwise, P2 will function normally.
4. In menu Fine Tuning -> Butterfly assign the newly created
switch L1 in the standard way and try its operation.
109

1. Sound Switch Assignment
Select the “Switch” menu item and assign the switch that you want
to use to trigger the sound playback.
2. Select the Sound File
Select the “File” menu item and select the sound file that you want
assigned to the switch. The available audio files are stored in
Directory/Audio. This is important to remember if you upload your
own files.
3. Sound Playback Delay
The playback of any sound, after activation, can be delayed by
editing the “Delay” menu item.

computer radio control system

2. To add control points, you should move the timeline (edit
“Time” column) so that it reaches the desired time. Then press the
„F3 Add” button. The newly created control point will be
highlighted and you can change its value (edit the “Value” column).
Generally said, the point located closest to the timeline is
highlighted and made editable.
3. You cannot move the control points in a time domain but you
are able to delete any point by pressing „F4 Delete” button.
4. Now, when you activate the source switch, the timeline begins
moving and the output of the sequencer is updated accordingly. If
you deactivate (turn off ) the switch, the sequencer moves in the
opposite way.

4. Sound Repeat
This menu item allows you to repeatedly play any sound after it has
been activated. This can be useful if your selected sound’s playing
time is short.

9.3.6 Sequencer

(* depending on equipment)

While this function can be used for direct control of landing gear
servos, its usage is almost limitless. Two independent sequences
might be used when you turn the source switch on and off.
You can define up to 6 sequencers Q1-Q6 and within each
sequencer you can define up to 16 control points for each path.
Switching between different sequencers is possible by pressing the
„F1 Down” and „F2 Up” buttons.

To make a sequencer active, you should do the following steps:
1. Assign a source switch. In the picture a), the Sg was selected.
After this switch is activated, sequencer starts running. But first it has
to know a path that consists of control points which are distributed
over a period of time.
110

There are some additional options that you can now set in the
Advanced menu:
•
You can label the sequencer to simplify identification.
•
The option to overwrite a specific channel. Example: If you
have several gear servos installed in your model, here is where you
can define which servo will be directly controlled by the sequencer.
Any other operations (like mixing or DR/Expo) will not be applied to
the output.
•
Type of path (Symmetrical / Asymmetrical) – this option tells
the sequencer that there is either one symmetrical path, or there are
two independent paths – one path is used after you activate the
switch and another one after the switch is turned off. If you choose
the Asymmetrical option, the sequence will always start from the
very beginning and it doesn't matter whether the previous
sequence is completed or not. It is recommended to use this option
in conjunction with the Always finish sequence option.

computer radio control system

Within this menu, you can edit
following parameters:
Filtering
– This increases
smoothness of the movement for
each axis separately. You can set
values in range from 0 to 10. Zero
value means no filtering and gives
fast reactions. The higher the
b)
filtering setting, the movement
becomes slower and smoother.
Sensitivity
– This influences
the gain of the inertial unit for each
axis separately. If you feel that the
reactions of the controlled
function are too small for the
particular movement, you can
simply increase the corresponding
value of sensitivity, numerically up
c)
to 400%.
Dead Zone
– This means that as the value is increased, the more
you can move the transmitter around the middle position and the
output of the inertial unit will remain zero.
Pitch Offset - This shifts the GY axis so that you don’t have to hold
or keep the transmitter in a completely horizontal position all the
time.

•
Cycling – if you wish a cyclic behaviour for your beacons,
turrets or radar assemblies just check this option.
•
Always finish sequence – After checking this option, the
sequencer will never be interrupted and always will travel from the
beginning to the end of its path.
•
The „F3 Clr” button clears all data from the sequencer and
resets it to the default state.

9.3.7 Accelerometer (DS only) (* depending on equipment)
The DS is equipped with an inertial unit that allows you to precisely
determine the orientation of the device in space. This unit consists of
a 3-axis gyroscope, 3-axis accelerometer and additional mathematic
operations. You can freely use this inertial unit to control any
function, trigger any voice announcements or you can simply flip
pages on the main screen.

You can configure some of the
i n e r t i a l u n i t p a ra m e te r s i n
Advanced Properties ->
Accelerometer. In the picture a),
the actual orientation of the
transmitter is displayed. The axes
GX, GY, GZ are defined as roll, pitch
and yaw in the same order. The
graph shows the final values after
all corrections have been made.

You can also view the raw data coming from accelerometer and
gyroscope by pressing the „F1 button” (see picture b) ). This might
help you to fine tune your setup.
111

computer radio control system

Up to 8 controls labeled MX1 – MX8 are available, depending on the
type of transmitter and equipment. Telemetry controls offer
functionality in two modes:
• The Switch mode enables you
to create a virtual two-position
switch using the value of one
telemetry parameter. This switch is
always active based on the
fulfillment of defined logical
conditions.
• The Proportional Control mode
enables you to transform a certain
range of sensor values into a fully
proportional control. It can
automatically and smoothly
control any kind of function using
telemetry feedback.

After you have finished setting the inertial unit itself, you can assign
the resulting variables to any function using a standard input dialog
(picture c) ). To see the variables of the inertial unit, you have to press
the „F2 Gsens.” button. The axes GX, GY, GZ correspond to the graph
shown in the picture a) ). The last parameters are called Shake L/R
and represent a motion gesture. If you quickly shift the transmitter to
the left, the G/L switch will be activated for a short time. Similarly, a
single movement to the right activates the G/R switch. You can use
these gestures to trigger voice announcements, flip pages of the
main screen etc.
The parameters "Axis X<<" and "Axis X>>" represent virtual twostate switches which are activated when the transmitter is tilted to
the left or to the right along the X-axis.

9.3.8 Telemetry Controls (*depends on equipment)
Not only can you display telemetry data, record it to your SD card or
have it voice announced, now it is possible to control specific model
functions using sensor inputs. This way, some tasks that previously
required manual adjustment via visual estimation or alarms can now
be automated.

112

computer radio control system
•
If the on-state of the limit switch is detected, the sequencer
automatically starts. (eg after opening the landing gear doors, the
main gear will be deployed).

Range – Set the operating range of the sensor (minimum value,
center value, and maximum value). This level will then be
transformed into a proportional range of the control (-100%, 0%,
100%). Available in Proportional control mode.
Filtering – Determines the level of received telemetry values
smoothing (filtering). The higher the level of filtration, the smoother
the course, but the response will be slower. Available in Proportional
control mode.
Default – The default control value, if the sensor is not present in the
model or the model is not turned on.
Switch – This parameter can specify any switch, which will activate or
deactivate the operation of the telemetry control.

Setting the parameters of telemetry controls
Description – Sensor name that will be displayed in the list for easier
orientation.
Active – Tick to enable the telemetry control function.
Sensor – Here you can select a specific telemetry parameter.
Type of control – Select Switch or Proportional control according to
the required functionality.
Condition (X<, X>, X=) – Select the condition under which you want
the control to be active (ie switched on). In the same line, fill in the
numerical value of the decision levels and the hysteresis value
(prefixed with ±). Available in Switch mode.
•
Example 1: The entry “X < 20.0m/s ± 2.0m/s” means that
telemetry control switches precisely when the telemetry parameter
value is less than 18 m/s (due to hysteresis of 2 m/s). The control then
symmetrically switches off when the speed exceeds 22 m/s.
•
Example 2: The entry “X > 0 ± 0” indicates a switch that is
activated whenever the telemetry value is positive.

9.3.9 Sound of Proportional Controls
In this menu, you can set a sound notification for up to four
independent controls. You can choose a basic beep in the middle
control position (Center-Beep mode), but voice announcements of
the current position is also available (Voice mode).

Duration – minimum time of being switched on. If an event takes a
very short time, it is possible to extend the time of the telemetry
control being switched on for the time specified by this parameter.
Available in the Switch mode.
113

computer radio control system

•
Center-Beep mode – the transmitter beeps whenever the
control goes to a central position (its deflection is thus 0%).
•
Voice mode – the transmitter will vocally announce the
numeric value of the current position of the control. The value is
reported after every change of the control position and only after
the movement is stopped. In this mode, you can also select an audio
file that will alert you when changes in control positions are
detected.
Example: If you generate the “CONTROL.WAV” file and then assign
it as the File parameter, the transmitter announces eg “Control:
twenty-five”.
The setting is always valid for the current model.

9.4.1 Timers (*depends on equipment)
The DC/DS allows you to simultaneously use up to 10 different
timers. This is useful to separately track motor run times, individual
lap times, total flight time or just about anything else you could
want. You can also name each of the timers. Once you create a timer,
it is displayed in its own box on the desktop screen. The timer values
are stored in each model’s setup. The „Timers“ menu displays a list
of all of the timers you have created.

b. Initial Timer Value
This is where you can set the starting value for the timer. You can set
a negative or positve value for this starting point.
c. Target Timer Value
Here is where you can set the target value for the timer. This can be
set as a positive value or a negative value. The initial value and target
value will determine the timer‘s direction. If the target value is
smaller than the initial value, the timer will count down. If the target
value is larger than the initial value, the timer will count up.
d. Timer type
There are three possible timer types:

9.4.2 Alarms
If you use the JETI telemetry system, in this menu you can set your
alarm thresholds and choose which sound is played in the alarm
condition. The transmitter supports both first generation Duplex
and Duplex EX alarms.

EX Alarms
Duplex EX sensors generate their alarms directly to the transmitter.
The corresponding Duplex EX sensor must first be connected to a
Duplex EX receiver and the receiver must be bound to the
transmitter. It may take several minutes for the transmitter to initially
communicate the sensors. The list of connected sensors is found in:
„Main Menu >Timers/Sensors >Sensors/Logging Setup“.
For this operation, both the transmitter and all receivers and sensors
must be connected and powered.

First Generation Alarms
First generation Duplex (non-EX) sensors generate their alarms as
Morse Code. If you are using first generation Duplex sensors, then
you must select „Enable Morse Code Alarms“ using the „3D
button“. When this option is selected, a table appears. In this table,
the first column shows the Morse Code alphabet. The second
column shows the .wav sound files associated with each letter. Use
the „3D Button“ to change the .wav file association as needed. The
third column shows whether the selected .wav file for each letter is
enabled. Use the „3D button“ to enable or disable the alarm sound
as needed. This configuration must be set for each model and is
saved for each model independently.

1. Creating an Alarm

Using the „3D button“, select „Enabled“ and press to enable the
alarm and display the alarm parameters.
3. Parameter Values
„Condition“ defines the condition which must be met in order to
trigger the alarm. The value „X“ will vary with the sensor being used.
4. File
This item allows you to select the audio file that is played when the
alarm occurs. Press „F1“ to play the selected audio file. Press „F2“ to
stop playing the selected audio file.
5. Activation Switch
If the switch is assigned, the alarm is enabled or disabled according
to the switch status.
6. Repeat
If the alarm condition occurrence is longer than the selected audio
file, you can use this item to repeat the audio file. If a check mark is
displayed then the audio file will repeat. If an „x“ is displayed then
the audio file will play only once.
7. Announce current value by voice
EX Alarms provide the ability to tell you the actual value of a given
sensor’s variable. If you want the alarm value to be announced, then
check this option.
8. Set Throttle Idle
With this item activated, you model’s throttle will go to idle when the
alarm condition occurrs.

Located in: „Menu->Timers/Sensors/Vario”. There are two types of
acoustic signalling. The first one is controlled directly by the sensor's
alarm. This is mainly useful if a non-EX MVARIO is installed inside the
model. It is possible to assign a switch that enables or disables the
sound. The slider at the bottom shows the actual value of climb/sink
rate.

The second mode of the Vario is dedicated to EX sensors. The
acoustic signalling varies directly depending on the actual
numerical values sent by the sensor. It is also possible to assign a
switch that enables the acoustic signal.

Other parameters displayed in this menu are:

9.4.4 Voice Output (* depending on equipment)

•

EX Parameter. Here you can select your sensor and its
parameter which will act as a source for the Vario system. The Climb
Rate is predefined by default (if the MVARIO EX is detected) but you
are free to choose one of the other sensors and their parameters (for
example: an RPM probe to indicate high revolutions).

This powerful function makes it easier for all modellers who need to
know their actual telemetry values often but they don't want to (or
cannot) look at the display because it may be inconvenient or
dangerous.

• Dead Zone (negative and positive). This field sets an area
around the centre of the range with no acoustic signal. Values are
relative to the center.

Voice output for a timer
The first menu row represents settings for the voice output of a timer.
The actual status of a single timer can be expressed by a synthesized
voice. If you select the desired timer and a switch, every time the
switch is activated the actual time is stated aloud.
If the timer type equals “Laps” type, another menu row equipped
with checkbox appears below. In this row, “Report previous lap”
allows you to determine whether you want to hear the time of a
current lap which is already running or hear the time of the previous
lap which has ended recently.

• Range (minimum, center and maximum). Here you can define
the full range of the sensor which will be indicated by the Vario
system.
The actual value of the sensor and its appropriate Vario output are
indicated at the bottom of the screen.

Voice output for telemetry
There are two independent queues dedicated to output telemetry
values. The first queue repeats its message every x seconds (number
of seconds elapsed is displayed over the F(1) button). You can also
assign a switch to enable or disable the repeating of the countdown.
Every time this switch is activated, the appropriate variables are
reported by voice and then the countdown starts a new round until a
timeout is reached.
The second voice queue specifies which variables are reported only
once, after a single press of a switch. You can select a Trigger switch
and a list of variables that are reported when the switch is activated.

9.4.5 Sensors/Logging Setup
This menu lists all of the Duplex EX sensors and their values which
are operating in your model. When you connect a sensor to a Duplex
EX receiver, it may take several minutes for the sensor to be
recognized by the transmitter and added to the list.
In this menu you can edit the telemetry parameters of each sensor.
By selecting the pushing the “Sensors & Variables” option using the
3D rotary button, you are able to choose which variables will be
expressed by a synthesized voice. The first column represents the
name of the sensor or variable. The Repeat option provides an easy
way to add a variable to the Repeat queue or to remove a variable
from the Repeat queue. By selecting the Trigger option, the specified
variable is added into the Trigger queue, so that every time the
Trigger switch is activated, the items in the Trigger queue are
expressed by synthesized voice.

You may change the priority of any variable. This will also change the
order of the reported items. Possible choices for priority are: Low,
Medium and High. The order, top to bottom, is from High priority to
Low priority.

It is possible to store service information of the transmitter, alarms,
and position of up to 4 controls (as markers) on your SD card. Then
the data is a part of logged flight telemetry. In the menu
„Timers/sensors -> Sensors/Logging” setup go to the item
Transmitter status info and push the 3D button. In the menu it is
possible to select whether the text information about the alarms and
other general data about the transmitter state will be stored (by
default it is disabled). Note that some PC programs for the evaluation
of telemetry data can recognize the text information as an error in
the data file. To view the information, you should use the built-in
Data analysis application or update the PC program.
In this menu you can also select up to four controls whose position
will be recorded in a file on the SD card. It is possible to select
120

computer radio control system
between recording of proportional or two-state values (0% – 100%).
The control positions are recorded with a fixed period of 0.2s. The
data is a part of the standard telemetry record and can be displayed
as the other parameters.
This application can easily be used as a marker to highlight
interesting situations during the flight.
Conversion of Units
1. The voice synthesized telemetry units can be expressed in either
metric or US units. It is also possible to display the telemetry units on
the main screen in either format as well. The temperature is
automatically converted according to the option selected in the
Configuration menu. Conversion of the other units is accessible
through the Sensors/Logging menu. You can choose from the
following units:
Distance:
Metres (m), kilometres (km), feet (ft.), yards (yd.), miles (mi.).
Speed:
Metres per second (m/s), kilometres per hour (km/h), feet per second
(ft/s), miles per hour (mph) and knots (kt.).

The user blocks can be either standard or double size. Double sized
blocks obviously use up more of the desktop. In return, some of
them display more data while others display the same data in a
larger font.
Custom blocks can be linked to flight modes. This means that you
can set up different groups of blocks for each flight mode creating a
completely different desktop appearance from one flight mode to
another.

1. Creating a new user block
In the “Displayed Telemetry” menu, press the “F3(Add)” button to
add a blank user block to the list. Using the “3D button” change the
first item of the new block’s line to the type of block you want to
create. Next, in the second line item, select whether you want the
new block to be double size (yes) or not (no).
2. Change the User Block order
Using the „3D button“ highlight your selected user block in the list.
Use the „F1“ and „F2“ buttons to move your selected block up or
down the list.
3. Deleting a User Block
Use the „F4(Del)“ button to delete the selected user block from the
list.
4. How the User Blocks are Displayed
The right end of the first line in the „Displayed Telemetry“ menu
displays a symbol to indicate if the list of user blocks is displayed for
all flight modes or just the current flight mode. If the „G (Global
symbol)“ is displayed then the all of the listed user blocks are
displayed in all of the flight modes. This means that when you
change flight modes, your desktop display will not change. If the „S

computer radio control system
(Separate symbol)“ symbol is displayed then the current list of user
blocks are only displayed in the current flight mode. This means that
when you change your flight modes, the desktop display will also
change. When using separates you must create a user block list for
each flight mode. You can change from Global to Separate by
highlighting the first line and pressing the „3D button“.

Note:

9.6.8 Limitations in copying models between transmitters

Note: Leaving the menu disables the connection.

When copying models from one transmitter to another one, it is
necessary to bear in mind that the transmitters may not have the
same software equipment. Thus it is possible that the configuration
of the activated modules may not correspond. In this case it is
necessary to check individual features of the model. Loading the
model memory to a different transmitter with different activated
modules can be carried out, but according to the use of individual
modules the transmitter can display warnings or does not allow
loading the model. The table (9.6.8) shows the conditions under
which a warning message will be displayed indicating that the
model will be loaded in a limited form, or will not load at all.

9.6.10 Info
This menu displays information about your DC/DS such as: product
name, firmware version, available memory, etc. Press the „F5 (Ok)“
button to exit this menu.

9.6.9 USB
This menu allows you to establish communication between your
DC/DS and a PC once you have connected the two with a USB cable.

9.7 Throttle Lock

9.8 Select Input control

Throttle lock is an important safety feature incorportated in your
DC/DS transmitter. This feature effectively "locks" the throttle
channel output leaving it at the last output value so that if your
motor is stopped, it cannot start accidentally. To activate/deactivate
the throttle lock go to the „Main Menu“ and then press the „F1
(lock/unlock)“ button. You will see the small padlock icon change
to indicate the lock/unlocked condition. Additionally, when the
throttle is locked, you will see a padlock icon appear in the center of
the top bar of the desktop.

This menu allows you to select your desired input control device
(switch, knob, stick or logical switch) for a given function. This menu
will appear any time you edit an input control device seletion. In this
menu you can also assign/edit how a control device functions. You
can set the control device to have two types of proportional output
or just a simple ON/OFF function. From this menu you can also
reverse the control device’s functional direction.

Hint: Use the throttle lock whenever you are handling a model

whose power system is active to eliminate the chance of
accidental activating the throttle and unexpected starting
of the motor.

135

3. Reversing
Press the „F3 (Rev)“ button to change the control device activation
direction.

1. Switch Assignment
When the menu appears, you can either press the „F1 (Log)“ button
to select/edit a logical switch for your function or you can simply
move the stick, switch or knob that you want to use to control the
function. When you move the chosen control device it will be
recogized and assigned to your function. The control device name
and current status is displayed. Once the control is activated you can
use the function buttons to configure the control device.
Hint: Think about what position/direction that you want the

control to work and move the stick, switch or knob into
position before you enter the assignment menu.
This will not reverse the output direction of your function. It will
simply reverse the direction of the control device (stick,
switch,knob).
4. Removing the Switch Assignment

10 Transmitter to PC Connection

10.2 Update firmware
The JETI Duplex line of transmitters fully support future software
updates. We recommend that you check the distributor’s and/or
manufacturer‘s web sites frequently for the most current update.
How to update your transmitter’s firmware:
1. Connect your transmitter to a PC via USB port
2. Confirm the connection
3. On the PC screen, open the partition of the transmitter and
extract the contents of the update file (*. Zip) to the root folder.
Confirm "overwrite existing files" if prompted.
4. After the successful data transfer, disconnect your transmiter
from the PC USB port and turn OFF the transmitter. The next
time that you turn your transmitter ON, the software will be
updated.
With any new firmware update no model setups or configuration
settings will be lost. For safety, after performing a new update, we
highly recommend that you check all functions, assignments,
configurations, and model mixes. A list of new features is always
released with the firmware update.

The JETI Duplex line of transmitters are equipped with a mini USB
port. The Transmitters also come with a standard USB to mini USB
cable which is used to connect your transmitter to a PC. The JETI
Duplex system is fully compatible with Microsoft Windows XP and
higher versions of Windows OS. After connection and confirmation
your transmitter will be identified by the PC as another memory
drive. While it is connected to a PC your transmitter‘s battery is also
being charged via the USB port.

10.1 Memory & System Files
After your transmitter has been connected to a PC it will behave like
standard external hard drive. Your transmitter’s file directory is
displayed on the PC screen. Pay close attention to moving, deleting
or adding files to any open file directory, any changes performed
here have a direct effect on your transmitter‘s internal data
File Directory
Audio – sounds, music, and acoustic warnings
Config – software configuration
Lang
– language configuration
Log
– telemetry data, all files use date stamp year/month/day
Manual – instruction manual
Model – programming files of individual models
Update – directory used for software updates
Voice
– audio samples for speech synthesis
Devices – device definitions used for communication with
intelligent devices based on EX Bus protocol

10.3 Sounds, Alarms & Acoustic Updates
At this time, the JETI firmware supports *.wav sound files. Any
sound file can be assigned to any function, switch, flight mode,
telemetry alarm, or music routine. Your applications are limited only
by your imagination. All sounds must be copied to the “Audio” file.

System Backup

10.7 Copying models between the transmitters

Data backup is as easy as the standard backup you can perform on
your PC. You can save all your data onto a PC hard drive or CD. The
saved data will, of course, reflect your last transmitter configuration
and model settings. The data recovery is as easy as copying your
backed up files back to the transmitter.

Configuration of all models in the transmitter are stored on the
internal SD card in the directory /Model/. When you copy the
selected model from one transmitter to another, simply copy the
*. jsn file again to the /Model/ directory of the second transmitter.
Note: It is important to bear in mind that the two transmitters

may not have the same software equipment, so it is
possible that the configuration of the activated modules
will not match each other. In this case it is necessary to
check the individual functions of the model, since an
attempt to load the model by another transmitter may end
up with error message.

10.5 PC Joystick
DC/DS transmitters can be very simply used as a joystick interface for
your PC. Connect your transmitter to a PC with the USB cable. Your
operating system will identify the transmitter as an HID (Human
Interface Device) gaming device.

10.6 Telemetry Data Logging
All telemetry data is stored on the internal SD card in the “Log”
directory file. Telemetry data files are easily identifiable as .log files.
The data files use date stamps with the “year/month/day”
configuration. Flight logs can be viewed on the PC using the JETI
“Flight Monitor” software.

11 Battery Safety Handling Rules

11.2 General Safety Rules

11.1 Transmitter Battery Pack

1. Any repair, installation, or upgrade must be
performed with caution and common sense. These will
require some basic mechanical skills.

1. The Installed battery pack must be charged from an AC voltage
source using only the included wall battery charger. The included
adapters work with local utility services, each country might be
supplied with a different type of charger.
EU: SYS1428-2412-W2E
UK: SYS1428-2412-W3U
US: SYS1428-2412-W2
Do not use any battery other than the manufacturer approved
Power Ion 3200 DC battery pack.
2. Always verify the correct polarity while connecting a
transmitter battery pack. The red lead is positive “+” and the black
lead is negative “-“ polarity.
3. Never test a battery pack by shorting the wire leads. Do not
allow the battery to overheat at any time.
4. Never leave your transmitter unattended at any time while it is
being charged.
5. Never charge an overheated battery pack, or in an
environment warmer than 158 F (70C).
6. During cold months always check the battery‘s capacity, do not
rely on your radio’s low battery warning system.
7. Always check your transmitter and receiver batteries prior each
flight. Do not rely on your radio’s low battery warning system.
8. Do not allow radio battery pack to come in contact with open
flame, other heat source or moisture at any time.
142

2. For any of the upgrades which require removing the radio back
cover you MUST disconnect the transmitter battery pack before
attempting any work.
3. It is imperative to store your radio in a controlled environment.
Any extreme temperatures can cause damage to the sensitive
electronics. A sudden change in temperature or humidity can create
condensation which can permanently damage your radio.
4. Do not use radio during poor weather conditions. Any water or
condensation can cause corrosion and could permanently disable
your radio. If you suspect that moisture has entered your transmitter,
turn it OFF, remove the back cover and let dry it out.
5. Avoid use in dusty environments.
6. The manufacturer is not responsible for any unauthorized
modifications. Changes or modifications not expressly approved by
the party responsible for compliance will void the user’s authority to
operate the equipment.
7. This is a sophisticated hobby product and not a toy. It must be
operated with caution and common sense, always avoid any
mechanical damage.
8. Always avoid operating close to devices that might cause
harmful electromagnetic interferences.
9. Keep all moving parts clean and free of dust or fine debris that
might damage the mechanical parts of the radio.

computer radio control system

direction of movement for your flight surfaces.
5. Set motor/engine kill switch and test the power train.

10. Do not point the transmitter antenna directly towards your
model or a human body. The radiation pattern from the antenna will
be shielded and provide poor connection to your model.
11. Never repair, re-install, or exchange the internal memory SD
card for other type.
12. Avoid extreme temperatures as they can cause damage to the
sensitive internal SD card.
13. Always perform a ground range check prior to your initial flight.

11.4 Application
This product may be used for model airplane or surface (boat, car,
robot) use only. It is not intended for use in any other application
than control of the models for hobby, sport and recreational
purposes.

11.3 Flight Safety Check
11.5 FCC /IC information

1. Always verify the correct position of the switches, and the
gimbals, prior turning ON your transmitter. Turn on the transmitter
first, then receiver. JETI transmitters use "Model Checking". This
safety is designed so that the model memory stores the unique serial
number of the receiver that has already been assigned to model.
When the transmitter establishes communication with the receiver
and the serial number does not match the number stored in the
current model’s setup, the transmitter displays a warning. You will
then be able to accept the change or reject the change. If you accept
the change, the transmitter stores the new receiver number into the
model’s setup and begins transmitting. If you reject the change, the
transmitter will not communicate with the receiver and you will be
allowed to select another model.
2. Perform a ground range check before each day’s flying session.
3. Check the battery voltage on both the transmitter and the
receiver battery packs.
4. Check all channel assignments, trim, mixes, and the correct

This is another popular sailplane mix. This mix allows you to
effectively change the airfoil of your model‘s wing by combining the
flaps and ailerons to lower the trailing edge (under camber) of the
wing. This helps to lower your flight speeds during landings or while
soaring. „Under camber“ is added to the wings when the flaps and
ailerons are deflected a little bit downward. Adding under-camber
means that the bottom surface of the wing becomes more concave.
To use this mix your wing configuration must be „2Ail“ or higher.
You can either use free mixer to set up this mix or you can use the
Butterfly mix. You can find the Butterfly menu in „Fine Tuning,
>Butterfly“.

12.15 Throttle Cut (Kill Switch)

12.16 Throttle Idle

This safety feature is mainly for models using glow or gasoline
engines as their main source of power. Electric models can also
highly benefit from this safety feature. The Throttle Cut function can
be activated using any assigned switch, knob or stick. By editing the
“Output Value” item, the throttle output will move to the user
defined (completely off) throttle position once the assigned switch
is activated. When the Throttle Cut is active, your throttle stick has no
effect on the throttle output.
You can find the Throttle Cut menu in: „Advanced Properties,
>Other Model Options, >Throttle Cut“.

This feature is used to set the idle position for your throttle and will
prevent your engine from shutting-off when you move throttle stick
to its low position. The minimum throttle setting is defined by
editing the “Throttle-Idle Offset” value. When this function has
been activated, the minimum throttle setting (idle point) is defined
by the offset value as a percentage. Standard throttle function is not
affected by the idle offset setting. You can find the Throttle Cut menu
in: „Advanced Properties, >Other Model Options, >Throttle Idle“.
