JETI DUPLEX RECEIVER EX R14 (JDEX-R14)

Fourteen-channel DUPLEX R14 modeling receiver operating in the 2.4 GHz band - compatible with DUPLEX modules, from the renowned Czech company JetiModel. With simple programming and pairing, compact dimensions, low weight and the ability to serially connect two or more receivers into one, as well as the ability to fully program mixers and channel functions (thanks to the optional Jeti BOX), the Duplex R14 is one of the most versatile receivers on the market. In addition, mounted optional telemetry sensors that transmit "live" information from the model to the transmitter via the receiver, further enhance the value of the product.

Why choose DUPLEX products ?

- Data transmission system does not use quartzes - no more problems with frequency selection
- Thanks to the universality of the modules, there is no need to buy a new transmitter !
- Easy and secure pairing of transmitter modules with receivers (you can use an infinite number of receivers capable of working with your transmitter)
- Unique coding ensures maximum operational safety and absolute "purity" of the signal without interference, even in a place where there are many devices operating in the 2.4 GHz band
- Digital data transmission eliminates the danger of distortion of the signal reaching the model
- Exceptional responsiveness of the receiver - immediate response to apparatus commands
- Can be used in any modeling application - Boats, Aircraft, Cars, etc.
- Two-way communication of the module with the receiver
- Easy programming and transfer of telemetry data from the model "live" - thanks to JetiBOX
- The high sensitivity of the receivers and the transmitting power of the module guarantee a very large working range of the system, many times exceeding the effective range of sight, even in adverse weather conditions
- Automatic correction of coded information
- Thanks to the possibility of linking two receivers together, up to 16 free-programmable receiver channels are at the modeler's disposal - the system at the same time does not require complex apparatus !
- Two receiver antennas guarantee signal continuity regardless of the current position of the model, eliminating the danger of so-called "blind spots" caused by wave reflections
- Selective selection of operating frequencies during the initial pairing of the transmitter with the receiver
- Built into the module, programmable audible alarm to warn in emergency situations (low battery voltage in the model, poor reception, etc.)
- DUPLEX system allows simultaneous operation of two or more receivers paired with the same apparatus
- Built-in Fail-Safe system with programmable response time
- Any receiver channel can be assigned to any transmitter channel
- All receivers allow you to set mixer, reverse, ATV or servo speed, even with the simplest transmitters
- Universal TU module built into the transmitter, allows leaving the 35 MHz module active and transmitting in two frequency bands

How does the 2.4 GHz DUPLEX system work ?

After powering up the transmitter and receiver, the module immediately recognizes the receiver and simultaneously selects 5 free channels from the 2.4 GHz band. The DUPLEX system then collects data from each selected frequency to determine signal integrity - data on signal strength and clarity, number of recorded errors, current position of the receiving antenna, etc. are inspected. As a result of a test performed before the moment of final pairing, two operating channels with the best characteristics are selected. If none of the 5, or only 1 of the "captured" channels meet the given standards for data transmission and reception, the test with five new frequencies is carried out again. The two selected and uniquely encoded channels operate in parallel, protecting the "jumped" signal, if necessary, from possible other 2.4 GHz transmitters operating in the area.

Real-time telemetry data transfer:

A universal device for programming and reading data from JetiModel products - "JetiBOX" - can also be easily and quickly connected to the DUPLEX product line. What is new, however, is the ability to read data wirelessly from the receiver and connected sensors while the model is running, even several hundred meters from the transmitter. Connecting directly to the DUPLEX module with a three-wire cable, on the JetiBOX display in real time you can read the current voltage of the power pack, the mAh consumed, the current consumption of the motor during its operation, the temperature or the GPS position in which your model is located ! (after prior installation of optional telemetry sensors in the model) It is also possible to program an alarm to warn of a given event, such as a drop in the voltage of the receiver's power pack below a pre-programmed value.

Optional telemetry sensors (list below) can also be connected directly to the JetiBOX reader when the model is not in use. With them, the device becomes a useful measuring tool - for example, the MUI sensor will become a voltmeter and ammeter in one !
