max. 12 as shown in the »Teacher/pupil« menu of the
teacher transmitter. Afterwards, assign the operating
elements appropriately.
Important:
• If you should forget to assign a trans-
mitter control on the pupil side, then
the affected servo or servos will remain
in the centre position when the transfer is
made to the pupil transmitter.
• The pupil transmitter must always be operat-
ed in PPM mode, regardless of the RF connec-
tion type used between the teacher transmitter
and the model.
• If the transmitter is connected using a DSC
socket on the pupil side, ALWAYS leave the
pupil transmitter's On/Off switch in the "OFF"
position: this is the only way to guarantee that
no RF signal is sent from the pupil transmit-
ter's transmitter module, even after the DSC
lead has been plugged in.
Trainer mode operations
Both transmitters are connected to one another using
a suitable lead (see summary on next page): The plug
marked "M" (master) must be inserted into the socket
on the teacher transmitter, and the plug marked "S"
(student) into the pupil transmitter's socket. (Note that
not all leads may have such "M" and "S" labeling.)
Important notices:
• Check that the model aircraft is opera-
tional and check that all functions is-
sue the correct commands BEFORE
setting up trainer mode.
• The ends of the trainer lead, usually marked
as either "S" or "M", terminate in a three-pole
TRS jack. Do not insert these jacks into a DSC
system socket, as it is not suitable for this ap-
plication. The DSC socket is exclusively de-
220 Program description - Teacher/pupil
signed for cables with 2-pole TRS jacks.
Checking functionality
Activate the assigned trainer mode switch:
• The trainer mode system is working properly if the
display now changes from " Teacher" to " Pu-
pil".
• However, if the WARNING LED at the right, next
to the transmitter's On/Off switch, blinks and an
acoustic signal sounds off at the same time, then
the connection between pupil and teacher transmit-
ters is faulty.
The basic display also displays the following warn-
ing notice ...

s i g n a l
... and the left side of the screen display for the
»Teacher/pupil« menu will change to show "-Pu-
pil". In this case, all control functions are retained
by the teacher transmitter automatically, regardless
of switch position: this ensures the model is always
under control.
Possible faults:
• Pupil transmitter not ready
• Interface in pupil transmitter not correctly connected
in place of the RF module
• Cables connected wrongly: see right for cable con-
nections
• Pupil transmitter not switched over to PPM (10, 16,
18, 24) mode
• Teacher transmitter not properly "bound" to HoTT
receiver in training model
• "EXT.PPM" in »Base settings« menu is "reverse".
Trainer cables
4179.1 for trainer operation between any two Graup-
ner transmitters equipped with DSC sock-
ets – distinguished by a two-pole TRS jack at
both ends.
3290.7 trainer cable for connecting a teacher trans-
mitter with DSC socket (e. g. mx-12 ...
mc-32 HoTT) or a transmitter retrofi tted
with an optional DSC module, No. 3290.24)
to a Graupner pupil transmitter with an op-
to-electronic system pupil socket – identifi able
by the mark "S" on the side of the three-pole
TRS jack.
3290.8 trainer cable for connecting a pupil transmit-
ter with DSC socket (e. g. mx-12 ...
32 HoTT or a transmitter retrofi tted with
an optional DSC module, No. 3290.24) to a
Graupner teacher transmitter with an opto-
electronic system teacher socket – identifi able
by the mark "M" on the side of the three-pole
TRS jack.
Further details about the cables and modules men-
tioned in this section for teacher and pupil trans-
mitters can be found in the respective transmitter
handbook, in the Graupner RC main catalogue or in
Internet at www.graupner.de.
