DC/DS Transmitters

Precise RC transmitters benefit from all of the features that the Duplex 2,4GHz EX system can offer.

The transmitters contain an advanced user interface that allows you almost unlimited programming. On-line and off-line telemetry are available as well as alarms, custom audio playback etc.

The design goals were maximum utility, durability, and reliablity of their mechanical parts along with simple handling. The metal case, with its chemically resistant finish, provides maximum protection for the interior components. The straightforward case shape makes servicing easy. The control gimbals, ball bearing equipped 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 3.5" sunlight readable color LCD 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 DUPLEX EX family of products have been equipped with an improved real-time telemetry system which can be viewed on the LCD transmitter display. The transmitter allows the setup of voice notifications, both preinstalled and user created, which can be related to telemetric values, user set alarms, or signals which have been assigned to conditions of various control elements.

The transmitters of the DS series are designed for thumb control.
These transmitters can be placed in a counter for these transmitters.

The second generation of the DS-14 transmitter

A variant of the top RC transmitter from the JETI model.

A color TFT LCD display placed on the top side of the transmitter offers perfect legibility at any lighting condition and a large surveillance angle. Thanks to the high display resolution and application of a relatively big ammount of graphic images it was possible to create a simple and intuitive setting procedure, especially for displaying telemetric data.

Duplex 2.4GHz – the DC/DS transmitters feature the Duplex 2.4GHz, frequency hopping, digital, data stream system, originally developed by JETI model in the Czech Republic. This system has been reliably used for many years.
Built-in Telemetry – from the start, the DC/DS transmitters were designed and built with many attractive features and include the full integration of all Duplex telemetry sensors.
Precise Gimbals – the transmitter gimbals are equipped with Hall sensors and ball bearings for precision movement with an almost unlimited lifespan.

Function curves
Makes it possible to use a curve to define the relationship between the position of the control and the resulting position of a servo. After activating this module it is possible to use the curve for any model function. The setting is available in Fine Tuning › Function Curves.
Gyro settings up to 3
Increases the number of gyroscope adjustable functions that can be used in one model up to 3. This way you can easily tune the gain of each axis of a flybarless stabilization system. The configuration of gyro functions is available in Fine Tuning › Gyro Settings.
Servo balancer
Activates the balancer function for up to 14 channels. The servo balancer is suitable for large models that have control surfaces driven by several linked servos. This can fine-tune the servo positions so that the resulting movement of the surfaces is synchronous without mutual force interaction. Servo Balancer is available in Model › Servo Setup.
Telemetry analysis via graphs
Activates the possibility of analyzing telemetry data from the records using graphs Then it is possible to analyze the time course for up to three telemetry values immediately after the flight. The function is available in Application › Data Analyzer.
Throttle limiter
Activates the function of adjustable throttle limiter. Suitable for model helicopters where it enables a smooth start from zero RPM up to a set RPM. Available in Fine Tuning › Throttle Limiter.
Voice output
Activates the voice interpretation of telemetry data via speaker or headphones. The numerical outputs of telemetry sensors are read to the user. Setting of individual announced values is available in Timers/Sensors › Voice Output.
Free Mixes up to 20
Increases the number of free mixes from 5 to 20. Configuration of free mixes is carried out in Fine Tuning › Free Mixes.
Logicswitches up to 16
Enables the function of 16 logical switches that determine their output according to the position of up to two assigned controls. You can also assign the output of each logical switch as the input of any model function. This way it is possible to create several virtual controls very easily that can be used to control the securing of landing gear, start timers or the activation of aerodynamic brakes. The configuration is available in Advanced Properties › Logical Switches.
Number of remote commands up to 16
Activation of 16 control commands for controlling devices connected via EX Bus. By the simple move of a switch on the transmitter it is possible e.g. to delete maximums and minimums recorded in the Central Box after each flight. The control commands can be understood as extra channels for additional functions of the model. The summary of active commands is to be found in Model › Device Explorer.
Sequencer up to 6
Activation of up to 6 user adjustable sequences. The start is carried out via an assigned control. Using the sequencer, you can easily achieve realistic landing gear retraction in scale models, in addition it is possible to control periodic events, such as position lights blinking. Setting the sequences is possible in Advanced Properties › Sequencer.
Timer up to 10
Increases number of timers from 3 to 10. Suitable for pilots in competition categories, where they perform several tasks in a specified time. The pilot thus gets a perfect overview of the flight time, motor time or a lap time. The configuration of timers is available in Timers/Sensors › Timers.
Values on display up to 40
Increases maximum number of telemetry items displayed on the main screen from 10 to 40. If you want to display a large number of telemetry data items, activate this option. The data can be easily arranged in individual screens through which you can browse. You can configure the displayed items in Timers/Sensors › Main Screen.
Event sounds up to 20
Increases the number of programmable sounds on events from 5 to 20. The sound file can start playing according to the condition of the assigned driver. Suitable as notification if extra functions of the model are active, such as landing gear retraction or flaps activation. The configuration of sounds on events is available in Advanced Properties › Sounds on Event.
Alarms up to 40
Increases number of user adjustable alarms from 10 to 40. Select this feature if you want to be always kept informed about the condition of your power batteries, exceeded height or of any other data. Example: If you set several successive alarms on reaching certain battery capacity, you will always be informed about the phase of your flight and if it is necessary to land. If you have the „Voice Output“ mode activated, you can also get information about the value of a specific data item. Setting the alarms is available in Timers/Sensors › Alarms.
Telemetry Controls up to 16
Not only can you display telemetry data, record it to your SD card or have it voice announced, with this module 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 (for example, when the pressure drops to the set value, then the gear opens automatically, it is also necessary to use the function of the logical switch). Up to 16 controls labeled MX1 – MX16 are available.
Voice Commands up to 16
Double Path
"Double Path“mode – the transmitter RF module communicate independently 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 the 2.4GHz Duplex module communicates independently with two receivers. This greatly improves safety and reliability since both receivers communicate independently with the RF module.
Flight Modes - up to 10
Increases the number of programmable flight modes from 3 to 6. Good choice if you fly with helicopter or glider models and the basic number of flight modes is not enough for you. Setting of the flight modes is carried out in Fine Tuning › Flight Modes.
Channels - up to 14
Increases the number of the transmitter channels from 10 to 14. If you fly large model airplanes with advanced wing mechanization and 10 channels is not enough for you, activate this module.
