Binding Receivers; Range-Checking - GRAUPNER MX-10 HOTT Programming Manual

Receiver output
For maximum fl exibility in terms of receiver socket
assignment, the optional Smart-Box provides the means
to swap over the servo outputs 1 to max. 6 - „channel
mapping"; see also chapter „telemetry" on page 113.
With the Channel mapping function of the Smart-Box
the six control functions of the mx-10 HoTT trans-
mitter can be shared out between several receivers if
necessary, or alternatively several receiver outputs can
be assigned to the same control function; for example,
you may wish to be able to operate each aileron with
two servos, or to control an oversized rudder using two
coupled servos instead of a single one.

rx bind
Graupner HoTT receivers have to be "instructed" to
communicate exclusively with a particular model (i. e.
model memory) of a Graupner HoTT transmitter. This
process is known as "binding", and is only necessary
once for each new combination of receiver and model. It
can be repeated at any time.
Important note:
When carrying out the binding procedure, please
ensure that the transmitter aerial is always an
adequate distance from the receiver aerials: keeping
the aerials about 1 m apart is safe in this respect.
Otherwise you risk a failed connection to the down-
link channel, and consequent malfunctions.
"Binding" multiple receivers to one model
If necessary, it is possible to bind more than one recei-
ver to a single model. This is accomplished by initially
binding the receivers individually, as described in the
next section. When operating the system, please note
that only the receiver which was bound last will
establish a telemetry link to the transmitter. For this
reason all telemetry sensors installed in the model must
be connected to this receiver, since only the last bound
receiver is able to transmit their data via the down-link
channel. The second, and all other receivers, run in
parallel to the receiver last bound to the transmitter, but
completely independently of it; they operate in Slave
mode with the down-link channel switched off.
If a receiver is switched ON which does not transmit te-
lemetry, the Status-LED changes from orange to green.
"Binding" transmitter and receiver
Note: The mx-10 HoTT can be bound in the mode „nor-
mal" only. Make sure before you start the binding pro-
cess, that the transmitter is programmed in this mode.
See page 88 for mode setting.
Turn the transmitter ON and then power up your recei-
ver: At the receiver, the green LED flashes once briefly,
and then goes out.
The LED on the transmitter lights up green to show that
no bound receiver is connected.
Press and hold the SET button on the receiver until the
green LED starts to flash.
Briefly press the BIND-button of the transmitter to initiate
the so-called binding process.
If the receiver LED glows a constant green within about
ten seconds, then the binding process has been com-
pleted successfully; you can now release the receiver's
SET button.
Your model / receiver combination is now ready for use.
In parallel with this the Status-LED switches from green
to orange:
Conversely, if the green LED on the receiver fl ashes
for longer than about ten seconds or the transmitters
Status-LED remains green, then the binding process
has failed. If this should occur, alter the relative position
of the aerials, and repeat the whole procedure.
range test
The integral range-check reduces the transmitter's out-
put power in such a way that you can test the system's
operation at a distance of up to about fi fty metres.
Carry out the range-check of the Graupner HoTT
system in accordance with the following instructions. We
