Note:
The switch assignment just described also
determines the transmitter used to issue the
teacher and pupil functions, respectively. For
this reason, a pupil transmitter must NEVER be
assigned a switch on this menu. The header line
therefore also switches from “Teacher / Pupil” to
“Teacher / Teacher” once a switch has been
assigned.
The model to be controlled by the pupil must be pro-
grammed completely – i. e. with all its functions includ-
ing trims and any mixer functions – in one of the model
memories of the
mc-16 HoTT or mc-20 HoTT
teacher transmitter. The HoTT receiver of the model in
question must also be “bound” to the teacher transmit-
ter, since the latter ultimately controls the model, even
in pupil mode.
ALWAYS ENSURE YOU SWITCH ON THE
teacher transmitter FIRST BEFORE PLUG-
GING THE CONNECTION CABLE INTO
THIS UNIT. Otherwise the RF module will not be
activated.
The
mc-16 HoTT or mc-20 HoTT teacher trans-
mitter can be connected to any suitable pupil transmit-
ter, even transmitters using the “traditional” 35/40 MHz
range. This means, for example, that a mc-16 HoTT
or mc-20 HoTT teacher transmitter can indeed also
be connected to a mc-24 pupil transmitter.
However, if the pupil-side connection is NOT
made via a two-pole DSC socket but rather via
a three-pole trainer socket (for example, out of
the Graupner product line), then the basic prerequi-
site for a correct connection to a pupil transmit-
ter – which is completely independent of the type
of modulation used in the teacher transmit-
ter – must ALWAYS be set to modulation type
PPM (10, 16, 18 or 24) in the pupil transmitter.
Pupil transmitter set-up
The model to be controlled by the pupil must be pro-
grammed completely, i. e. with all its functions includ-
ing trims and any mixer functions, in one of the model
memories of the teacher transmitter and, if applicable,
the HoTT receiver of the model in question must also
be “bound” to the teacher transmitter. In principle, a
mc-16 HoTT or mc-20 HoTT pupil transmitter can
also be connected to a teacher transmitter operating
on the “traditional” 35/40MHz bands. This is pos-
sible because the PPM signal required by the teacher
transmitter is available in the (pupil) transmitter’s DSC
socket.
Almost any transmitter with at least four control func-
tions from previous and current Graupner series can
be used as a pupil transmitter. More detailed informa-
tion can be found in the RC main catalogue and on the
www.graupner.de/en website.
If required, the pupil transmitter should be fitted with
the connection module for pupil transmitters. This is to
be connected to the transmitter board in accordance
with the supplied installation instructions.
Information on the pupil modules required in each case
can be found in the Graupner RC main catalog and on
the www.graupner.de website.
The connection to the teacher transmitter is made
using the appropriate lead; see the following dou-
blepage.
The control functions of the pupil trans-
mitter MUST act directly on the control
channels, i. e. the receiver outputs, with-
out intermediary mixers.
If you are using an “mc” or “mx” series transmitter, it is
best to activate a free model memory with the required
model type (“Fixed-wing” or “Heli”). Assign the model
name “Pupil” and set up the stick mode (mode 1 …
4) and “Throttle min. forward/back” to suit the pupil’s
preferences. All other settings are left at their default
values, however. If you have selected the “Helicopter”
model type, you must also set the throttle/ collective
pitch direction and idle trim on the pupil transmitter. All
other settings, including mixer and coupling functions,
are configured exclusively on the teacher transmitter,
which in turn transmits them to the model.
If the pupil transmitter is a mx-20 HoTT,
mc-16
HoTT, mc-20 HoTT or mc-32 HoTT series model
then it may also be necessary to adapt the type of
modulation in the “DSC output” line of the »Base
setup model« menu in order to accommodate the
number of control channels to be transmitted. For ex-
ample, the signal packet for modulation type “PPM10”
contains only control channels 1 … 5 but not channel 6
and upper. However, if this channel is to be used by the
pupil then a modulation type must be selected in which
it is included. A further point is that “HoTT” must be en-
tered in the “Module” line of the »Base setup model«
menu if you wish to set up one of the transmitters in
Pupil mode, but using an existing model memory rather
than a newly initialised memory. If you neglect this it is
possible that the PPM signal present at the DSC sock-
et will be inverted.
For transmitters of – older – type “D” and “FM” it is
necessary to check servo operating directions and their
control correlations. It may be necessary to reconnect
cables appropriately. All mixers must also be switched
off or set to “zero”.
If other control functions are to be transferred to the
pupil transmitter in addition to the functions of the two
dual axis sticks (1 … 4), access the »Control adjust«
menu in the pupil transmitter and assign those inputs
which correspond to enabled function inputs 5 …
