The Duplex system takes advantage of the 2.4GHz band for communication. This system not only transmits control data to the model but also sends data from the model back to the transmitter. The telemetry data collected during operation is shown as actual, measured values in real time on either LCD screen of a connected JETIBOX or on the DC/DS JETI model transmitters.
Assignment of the MUI EX sensor is measurement of voltage, current, and consumed capacity of flight batteries in the model. The wireless data transmission by the DUPLEX 2,4GHz system is monitored by the JETIBOX terminal.
For communication purposes the Duplex
system takes advantage of the 2,4 GHz band which, besides sending remote
control data to the model, also receives data from the model back to
the transmitter. During a flight, obtained telemetric data are
transmitted in real time and the actual values of the measured data can
be displayed on the JETIBOX LCD. Telemetric MUI sensors execute voltage
and current measurements in your model and transmit these informations
with the aid of the DUPLEX system (receivers and transmitter modules).
Thanks to exact current measurements these sensors make it possible to
trace the spent capacity of the measured battery. The MUI unit is
recording the spent current flow time and its average as well as maximum
value. Furthermore it offers exact voltage measurements and recordings
of voltage minimum and maximum values.
The task of parameter adjustment and measured data setup is performed by the well known talent – the JETIBOX terminal.
MUI sensors allow setting of acoustical
signals in order to announce violation of set parameters. Such alarms
may be set for measuremets of maximum current and minimum voltage as
well as for a maximum of consumed battery capacity. The sound signal is
generated by a siren integrated in the transmitter module. For better
differentiation the particular alarms are distinguished by Morse
alphabetic letters. The acoustical alarm generation in case of parameter
violation is working even if the JETIBOX is not connected. With the
JETIBOX in place, the LCD display shows which parameter has been
violated. In case of violation of several parameters the alerts alter
consecutively as well as the indications on the LCD display.
