The five-channel DUPLEX R5 L full-range model micro-system operating in the 2.4 GHz band - compatible with the DUPLEX modules, the renowned Czech company JetiModel. Thanks to simple programming and pairing, compact dimensions, low mass and the possibility of serial connection of two or more receivers into one, as well as the possibility of full programming of mixers and channel functions (thanks to the optional Jeti BOX). The Duplex R5 L has been designed for use in small to medium models and enables the use of Jeti Model telemetry.

Why is it worth choosing DUPLEX products?

• The data transmission system does not use quartz - the end of problems with frequency selection

• Thanks to the universality of the modules, there is no need to buy a new transmitter!

• Easy and safe pairing of transmitting 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 "cleanness" 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 risk of distortion of the signal reaching the model

• Exceptional response speed of the receiver - immediate reaction to the commands of the apparatus

• Can be used in any modeling application - Boats, Planes, Cars, etc.

• Bidirectional communication between the module and the receiver

• Easy programming and transfer of telemetry data from the "live" model - thanks to JetiBOX

• High sensitivity of receivers and transmit power of the module guarantee a very large 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 ability to connect two receivers with each other, as many as 16 slow-programmable receiver channels are available to the modeller - the system does not require any complicated devices!

• Two antennas of the receiver guarantee continuity of the signal regardless of the current position of the model, eliminating the threat of so-called "Blind spots" caused by the reflection of waves

• Selected selection of operating frequency during the initial pairing of the transmitter with the receiver

• Built-in module, programmable audible alarm for warning in emergency situations (low battery voltage in the model, poor reception, etc.)

• The DUPLEX system allows simultaneous operation of two or more receivers paired with the same equipment

• Built-in Fail-Safe system with programmable reaction time

• Any receiver channel can be assigned to any transmitter channel

• All receivers enable setting of mixers, reverse, ATV or servo speed, even with the simplest transmitters

• Universal TU module incorporated into the transmitter, allowing the active 35 MHz module to be left and transmitted 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 in order to determine signal coherence - data on signal strength and cleanliness, number of recorded errors, current location of the receiving antenna, etc. as a result of the test before the final pairing is performed, two work channels are selected characterized by the best properties. If none of the 5 or only 1 of the "captured" channels meet the given transmission and reception standards, the test with five new frequencies is carried out again. Two selected and uniquely coded channels work in parallel, securing a "skipping" signal, if necessary, against any other 2.4 GHz transmitters working nearby.

Real-time telemetry data transfer:

Universal device programming and reading data from JetiModel products - "JetiBOX" - can be easily and quickly connected to the DUPLEX product line. The novelty, however, is the possibility of wirelessly reading data from the receiver and the sensors connected to it during the model's operation, even several hundred meters from the transmitter. By connecting directly to the DUPLEX module using a three-wire cable, the JetiBOX display in real time can read the current voltage of the power pack, the used amount of mAh, current consumption during its operation, temperature or GPS position in which your model is located! (after previous installation in the optional telemetry meter model) There is also the possibility of programming an alarm warning against a given event, such as, for example, a voltage drop in the packet supplying the receiver below the previously freely programmed value.

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