THANK YOU
for purchasing the General Engine-Module for the Graupner HoTT 2.4 system.
If you do not have the Graupner HoTT 2.4 radio system this product will not work. This product is not com-
patible with any other 2.4GHz radio system.
Please read through this entire manual before you attempt the installation and usage of your Graupner HoTT
General Engine-Module!
These operating instructions are part of this product. They contains important notes to the operation and
handling. Please take this into consideration when you pass on the product to third parties. Neglect of the
operating instructions and the safety instructions lead to expiring the warranty.
Graupner constantly work on the advancement of all remote control systems; changes of the scope of deli-
very in form, technology and equipment we must reserve ourselves therefore. Please have understanding
for the fact that from data and illustrations of this operating instructions no requirements can be derived.
Please keep these instructions for further reference!
DESCRIPTION
1.
The Graupner-HoTT General Engine-Module enables the wireless monitoring of for example the battery
voltage, power consumption, motor rpm, or fuel consumption of the model in real time. The General Engine-
Module can be programmed directly with all HoTT transmitters with integrated telemetry in the transmitter
display (some models such as MC-24 with update or modi
fi
cation).
The following transmitters must be programmed via SMART-BOX order No. 33700:
mx-12 HoTT order
No. 4754, mx-16 HoTT order No. 4755, and mx-22 No. 4801/4802, mc-19 No. 4821 and mc-22 No. 4818
after conversion to HoTT. This differentiation between the transmitter models and the resulting operation is
explicitly mentioned at the appropriate point in the instructions (see also point 5).
For full functionality, additional sensors are necessary.
Informations available - Setup:
Battery voltage (total - single cell), Min./Max. voltage, Min./Max. cell voltage
Maximum current, used capacity
Temperature (optional Sensor 1/Sensor 2), Min./Max. Temperature
Fuel level, Min. fuel level,
RPM, Minimum/ Maximum RPM
Note:
Any settings you make on the Transmitter or SMART-BOX will be stored in the General Engine-
Module only!
Since the General Engine-Module can be updated via the USB connection, you always have the latest soft-
ware and can utilize future functions or languages. Firmware updates for the General Engine-Module can
be transferred via the DATA or telemetry interface in conjunction with a PC running Windows XP, Vista or 7.
For this you also require the USB interface, Order No. 7168.6, the adapter lead, Order No. 7168.6A and a
Y-cable Order No. 3936.11 which are available separately.
The programs and
fi
les required for this are available from www.graupner.de in the Download area for the
corresponding products.
2. MOUNTING THE MODULE IN THE PLANE
Mount the General Engine-Module at an appropriate location in the model. The best way to
fi
x the General
Engine-Module with the mounting tabs or double sided tape on a wind-protected frame in the model, the
orientation of the sensor is not important.
3. CONNECTION OF SENSORS
The consumed current and capacity is measured only on connection 1 (IN) and 8 (OUT). Therefore, the
main battery for the motor (electric model - G3.5 connector) or the transmitter battery (Nitro model - JR con-
nector) must be connected to this connection. Use a connector system to replace the battery easily. If you
use a LIXX battery, the balancer can be plugged into socket 6 to monitor the individual cell voltage.
