DSC
The transmitter's upper display will show the
message "CANNOT RECEIVE DATA" during this
time.
Thus the transmitter is ready for operation.
In contrast, the
mc-32 HoTT transmitter
in teacher mode is to be switched on prior to
plugging in the respective cable.
3. Connect the other end of the cable to the desired
unit in compliance with the given operating
instructions for that unit.
Important:
Pay attention that all plugs are inserted
securely 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 89 or 100 or the line "Pre-set DSC
Output" in the »General basic settings«, page
277, – depending on the number of functions
transferred – one of the following modes can be
set: PPM10, PPM16, PPM18 or PPM24. Default
setting: PPM10.
Notice about  ight simulators:
•
Because of the myriad of  ight simulators
available on the market, it may be
necessary to have the contact layout of
the audio plug or DSC module appropriately
modi ed by Graupner Service.
DSC / Direct Servo Control
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 face-side cover has been moved away,
the
mc-32 HoTT transmitter's DSC socket is ac-
cessible:
The standard two-pole DSC jack in the mc-32
HoTT transmitter is used as the teacher or pupil jack
as well as an interface to fl ight simulators or external
RF module.
To ensure a proper DSC connection, please observe:
1. Make any necessary menu changes.
Refer to the section beginning on page 226 to
adapt the
mc-32 HoTT transmitter to a teacher/
pupil system.
2. When operating a fl ight simulator or when
operating the
mc-32 HoTT transmitter as a
pupil transmitter, ALWAYS leave the transmitter's
ON/OFF switch in the "OFF" position 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 "
Battery " LED should remain
constantly illuminated and the transmitter's basic
display should show the character string "DSC"
below the operating time clock. At this time, the

Charger jack
The mc-32 HoTT transmitter's charger jack be-
comes accessible after turning the left face-side cover
away.
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 (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 18. Observe the safety
notices on pages 8 … 10 when handling lithium bat-
teries.
