Jeti Duplex 2,4Ghz

Jeti-s System är lite unik jämfört med konkurenterna då det redan är dubbelryktad kommunikation, mellan mottagaren och sändaren. Du får låg batterivarning när acken i kärran håller på att ta slut. Då sändareffekten på mottagaren är ca hälften mot sändaren "tappar" sändaren mottagarens signal innan mottagaren tappar sändarens signal, tack vare detta får du en varning (ton) om räckvidden. Två mottagare kan vara "anslutna" till samma sändarmodul , dom kan vara i serie för att få upp till 16 kanaler eller parallelt för att få högre säkerhet. Det unika med mottagarna är att dom kan programeras med Jeti boxen, direkt från sändaren (boxem är ansluten till sändarmodulen) i mottagarna kan du göra flera olika mixar , ställa ändlägen, mittlägen, expo , länka ihopp flera servon på samma kanal. På detta sätt sparar man rätt så många kanaler från radion och om du har enklare radion kommer detta ge dig många nya andvändara funktioner. Liknande funktioner kommer från Weatronic men då till lite högre pris.

Jag rekomederar detta system för den vanliga söndagsflygaren, då den kommer att höja säkerheten betydligt.

	System Duplex 2.4 GHz
We present the new innovative DUPLEX system by JETI Model for radio controlled models of all types working on the 2,4GHz band. Problems with interference and frequency control will be history, and operation on the 2,4GHz band will change your approach to radio control forever. In designing the DUPLEX system, our aim has always been to improve on what is offered by other radio control systems currently on the market. We offer you very sophisticated equipment offering reliable – duplex – secure – digital transmission of information.

	Main advantages of the DUPLEX system: - no crystals used – no frequency checks required - you do not have to buy a new transmitter - easy and reliable binding of receivers to transmitters (you can use endless numbers of receivers with every transmitter) - high interference rejection provides safe operation - even in an interference rich environment - digital data transmision ensures distortion free transfer of information to the model - maximum safety - can be used with all types of models (aircraft, boats, cars) - two way communication between receiver and transmitter - telemetric data transfer to the model operator in real time - high sensitivity of receivers and high output of transmitters ensures visibility limit range - self-correcting coding of information - the DUPLEX system can handle up to 16 input channels with the use of two receivers - two aerial receivers ensure continuous control of models in any position, and eliminate blind spots caused by signal reflection - quality plotting of transmission channels and antenna position at start up, providing a low probability of transmission on busy or interference rich channels - immediate response of the receiver output to changes in transmitter controls - transmitter modules are fitted with an alarm triggered by the receiver in dangerous situations (low receiver battery voltage, poor reception, etc.) - the DUPLEX system provides simultaneous operation of more than one receiver on the same transmitter (listening-in) - real time data display and easy programing using the JetiBox - failsafe with adjustable time delay. - receiver outputs can be changed to match any transmitter channel input - all of the receivers allow the setting of mixers, servo reverse, ATV, servo slow for each output on the receiver, even with the simplest of transmitters

	How does the DUPLEX 2,4 GHz system work? After switching on the transmitter and the receiver, the transmitter automatically acknowledges the receiver, and then both select free channels in the 2.4GHz band. The DUPLEX system then collects data on each channel selected for transmission integrity in relation to signal intensity, number of errors corrected, aerial position etc. If any channel is considered to be unfit for use, the channel is then changed to a new one by the DUPLEX system. These checks happen before the DUPLEX system selects two channels for operation (and then channel hops as necessary) to minimise potential clashes with other transmitters (or with other systems used on the 2.4GHz band), which allows common operation of more transmitters simultaneously.

	Transfer of telemetric data in real time: The JETIBOX terminal can be connected to the receiver or transmitter module to measure data. A valuable option is to connect the JETIBOX to the transmitter module and receive data wirelessly from the receiver and any sensors connected to it. Every DUPLEX receiver transmits the receiver battery voltage in real time. It is possible to set an audible warning which is activated by the voltage dropping below a pre-set limit. It is possible to connect a number of telemetric sensor to each receiver. The Jeti Telemetric sensors can also be connected directly to the JETIBOX. For example, connecting the MUI sensor to the JETIBOX creates both a voltmeter and ammeter.




	Telemetric sensors: MUI: - voltage measuring ( 0 to 60 V) – actual voltage, max and min voltage - current measuring (0 to 75A / 150A) – actual, average and max current - measurement of capacity used [mAh] motor on time MT: - temperature measuring ( -10°C to +150°C) – actual temperature, min and max temperature MGPS: -displays GPS position - model distance - model height - flight speed
