Transmitter description
Thus the transmitter is ready for operation. 
To the contrary, teacher mode for the 
mx-20 HoTT 
transmitter requires that the transmitter be switched 
on prior to plugging in the respective cable.
Connect the other end of the cable to the desired unit 
2. 
in compliance with the given operating instructions 
for that unit.
Important:
Be sure that all connectors are seated fi rmly in 
their respective sockets.
Notice about fl ight simulators:
Because of the myriad of fl ight simulators available on 
the market, it may be necessary to have the contact 
layout of the audio plug or DSC module appropriately 
modifi 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 technical 
reasons. 
The standard two-pole DSC jack in the 
mx-20 HoTT 
transmitter is used as the teacher or pupil jack as well 
as an interface to fl ight simulators.
To ensure a proper DSC connection, please observe:
Make any necessary menu changes.
Refer to the section beginning on page 
198 to 
adapt the mx-20 HoTT transmitter to a teacher/pupil 
system.
When operating a fl ight simulator or when operating 
1. 
the 
mx-20 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.
The main status LED should now constantly 
illuminate red and the transmitter's basic setup 
screen should show the string "DSC pupil" on the 
right just below the middle timer. At the same time, 
the display of telemetry indicators will be suppressed.

Card slot
micro SD and micro SDHC
With the 
mx-20 HoTT transmitter switched off, 
removing the battery compartment cover and the 
transmitter's battery will make the card slot accessible 
(located in the right sidewall of the battery compartment). 
This card slot is intended for micro SD and micro SDHC 
type memory cards.
All conventional micro SD memory cards up to 2 GB and 
micro SDHC cards up to 32 GB storage capacity can 
be used. However, as a manufacturer we recommend 
the use of memory cards no larger than 4 GB as this is 
completely adequate for all normal situations.
The type of memory card referred to here became 
known in conjunction with digital cameras and cell 
phones. It is to be pushed into the slot with its contacts 
upward, front facing the rear wall and latched in position 
there. After re-installing the battery and closing the 
battery compartment, the transmitter can be switched on 
again. The stylized image of a memory card will appear 
in the basic setup screen to indicate the presence of the 
inserted memory card.
