User Manual

The JETI DUPLEX EX series of receivers are designated to operate
with the JETI DUPLEX EX transmitters using the 2.4GHz band. Thanks
to the fully digital and bidirectional communication between the
transmitter and receiver the Duplex EX system offers many new
features and concepts for the remote control pilot.
The DUPLEX EX transmitters and receivers take advantage of the
latest modern technologies, precise manufacturing and exhaustive test
methods to provide a system that gives you maximum safety and
reliability. The DUPLEX EX system provides extended capabilities by
allowing the use of telemetry data transfer to give unparalleled insight
into the actual condition of your model during flight. The JETIBOX
PROFI allows you to view telemetry data either in parallel to the Jeti
Transmitters or as a stand-alone system when used with a Jeti
receiver. You can use the FlightMonitor program to view and analyze
your recorded telemetry data.
An additional R5 auxiliary receiver can be used to complement the R9,
R11, R14 and R18 receivers.
Power Supply:
You can supply power to Duplex EX receivers through the use of NiCd
batteries, stabilized voltage supplied by the BEC from your motor
controller or by using Li-xx cells and a voltage regulator like the MAX
BEC. Make sure that your selected power supply can yield enough
current to power all of the servos and the receiver in your aircraft. If
all servo connectors in your receiver are being used, you can use a Y-
cable to supply power to your receiver. You can supply power to your
receiver through any receiver output EXCEPT the output marked “Ext”.
This output is used only for telemetry sensors or expanders. The EPC
R11, R14 and R18 receivers are equipped with a separate Multiplex
power supply connector. We recommend that you use this connector
for the receiver and servo power supply because of its high current
capability and reliability.
Operation:
Operation of the DUPLEX system is very similar to an FM system. We
recommend that you switch on the transmitter first and then the
receiver. The transmitter confirms the on state of the receiver
sounding a short beep. When switching off the system we recommend
that you switch off the receiver first and then the transmitter.
