The transmitter’s upper display will show the mes-
sage “CANNOT RECEIVE DATA” during this time.
Thus the transmitter is ready for operation.
In contrast, the transmitter in teacher mode is to
be switched on prior to plugging in the respec-
tive cable.
3. Connect the other end of the cable to the desired
unit in compliance with the given operating instruc-
tions for that unit.
Important:
Pay attention that all plugs are inserted se-
curely into their respective sockets and use
only the prescribed 2-pole TRS connector
plugs on the DSC-side.
4. In the line „DSC Output“ in the »Basic settings,
model«, page 92 or 100, – depending on the
number of functions transferred – one of the follow-
ing modes can be set: PPM10, PPM16, PPM18 or
PPM24. Default setting: PPM10.
Notice about flight simulators:
Because of the myriad of flight simulators available on
the market, it may be necessary to have the contact
layout of the audio plug or DSC module appropriately
modified by Graupner Service.
DSC jack
The acronym “DSC” is a carryover which stands for
the original “Direct Servo Control” function. However,
in HoTT systems the “direct servo control” function is
no longer available via a diagnose cable due to tech-
nical reasons.
Once the left-hand side flap has been moved away,
the DSC socket is accessible:
The two-pole DSC socket fitted as standard to
mc-
16
HoTT and
mc-20
HoTT transmitters serves
both as Trainer socket (Teacher and Pupil) and also
as interface for flight simulators and external RF
modules.
To ensure a proper DSC connection, please ob-
serve:
1. Make any necessary menu changes.
Refer to the section beginning on page 222 to
adapt the transmitter to a teacher/pupil system.
2. When operating a flight simulator or when operat-
ing the transmitter as a pupil transmitter, ALWAYS
switch OFF the transmitter as only in this position
does the transmitter‘s RF module remain inactive
after the DSC cable is inserted. This also reduces
the transmitter‘s power consumption somewhat.
Only the red “

transmitter:
The transmitter’s rechargeable LiIo battery can be
charged by way of the charger socket located behind
a cover on the left, front side of the transmitter – as
viewed from the front – with the included plug-in
charger (order no. 32032.4).
Maximum permissible charging current with Graupner
automatic chargers: 1,5 A.
Never use plug-in chargers from other manufacturers
or chargers intended for other battery types. Charger
output voltage which is too high or possibly even
different plug polarity, see further below, can cause
immense damage.
More information about charging the transmitter’s
battery can be found on page 16. Observe the
safety notices beginning on page 8 when handling
lithium batteries.
