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 ad-
just« menu in the pupil transmitter and assign those
inputs which correspond to enabled function inputs 5
... 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
transmitter 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
operated in PPM mode, regardless of the
RF connection 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 transmitter'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.)
228 Program description - Teacher/pupil
Important notices:
•
Check that the model aircraft is
operational and check that all
functions issue 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 application.
The DSC socket is exclusively designed
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 " T" to " P".
WARNING
•
However, if the
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
transmitters is faulty.
The basic display also displays the following
warning notice ...
No
pupil
signal
... and the left side of the screen display for the
»Teacher/pupil« menu will change to show
"-Pupil". 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 con-
nected 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
Other possible faults:
•
Teacher transmitter not properly "bound" to HoTT
receiver in training model
