The DS-14 II transmitter uses the proven Jeti Model 2.4GHz Duplex system for wireless control of RC models. The transmitter has precise sticks with hall sensors, a graphic LCD colour display with backlight and a clear and intuitive way of programming. The DS-14 II transmitter offers a modular system of software features according to the requirements of each user. The transmitter is delivered with a basic configuration, which is is a good start for most new users. A colour 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 amount of graphic images it was possible to create a simple and intuitive setting procedure, especially for displaying telemetric data. The main goal with the design of the transmitter was maximum user comfort, exclusive appearance and longevity by exploitation of premium quality materials. The DUPLEX EX product family has been equipped with an improved telemetric data transfer system and the subsequent data processing on the LCD transmitter display or analysis on a PC. The transmitter allows the setup of acoustical notifications (optionally created by the user himself), which are related to the actual telemetric values or to sound signals assigned to conditions of particular control elements. For flight control and reception of telemetric data from the model to the transmitter, the DS-14 II takes advantage of the Duplex 2.4GHz wireless system, which has been developed by the JETI company as well. The Duplex 2.4GHz data transfer system is very reliable and has been verified for many years. Using the integrated microphone you can easily prepare your own audio files. Furthermore, you can teach the transmitter to respond to several voice commands. User Applications – the DS-14 II can be easily extended using third-party applications written in Lua programming language (www.lua.org).
