   Teacher/pupil
  Connecting two transmitters for trainer mode with a trainer lead
The
mc-20
 HoTT transmitter is equipped 
standard – as viewed from the front, under the left 
front fl ap – with a DSC socket. This is not only usable 
for connecting fl ight simulators – as described on 
page 22 –  but also to integrate the transmitter into a 
cable-coupled teacher/pupil system. 
To accommodate the settings necessary for this, 
scroll with the selection keys on the left or right touch 
pad to the »Teacher/pupil« menu option in the 
Multifunction menu:

Note:
The screen image shown above shows the menu 
in its initial state: No transmitter controls have been 
released by the pupil (  ) and no switch is assigned
("SW: ---" bottom left in the screen image).
When assigning control functions, the usual 
conventions must be observed:

1
Motor throttle/collective pitch

Aileron/roll

Elevator/pitch-axis
4
Rudder/tail rotor
Teacher-pupil settings
Up to twelve function inputs (see "Term defi nitions" 
on page 54) of the teacher transmitter "T" can be 
individually or in any combination transferred to the 
pupil transmitter "P".
The lower display line, designated with "T", therefore 
indicates the function inputs with which control 
functions 1 … 4 (joystick functions for fi xed-wing and 
helicopter models) are permanently connected as 
well as inputs 5 … 12, which can be freely assigned 
in the »Control adjust« menu. 
Note:
Just which controls are assigned to any inputs turned 
over to the pupil is basically of no consequence. 
However, their assignment in the »Control adjust«
menu is possible only when the trainer mode 
connection is inactive.
Use the 
ef selection keys of the left or right touch 
pad to select the function inputs 1 through 12 for 
transfer to the pupil
( ) then briefl y tap center 
SET
key of the right touch pad for each switch to be 
switched between "T(eacher)"( ) and "P(upil)" ( ):

To be able to carry out the transfer, you must then 
assign a trainer mode switch on the left of the display. 
Do this by placing the marker just to the right of 
the "P"at the bottom left of the screen display by 
using the selection keys of the left or right touch pad 
then assign a switch as described in the section 
"Assigning transmitter controls, switches and control 
switches" on page 56. 
Preferably you should utilize one of the two standard 
momentary switches on the switchboard to allow 
a return of control to the teacher transmitter at any 
time.

Since at this early stage of programming a trainer 
system it is unlikely that an operational pupil 
transmitter is connected to the teacher transmitter, 
the transmitter responds immediately to the switches 
closed during the switch assignment process with 
appropriate visual and audible warning notices. You 
should therefore re-open the switch you have just 
assigned:
