33601 VARIO Modul - Graupner HoTT 2.4
THANK YOU
for purchasing the Graupner HoTT VARIO MODULE.
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 SMART-BOX!
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 VARIO-Module enables the wireless monitoring of the altitude and the graphical and
acoustic indication of climbing or descent of the model in real time. The VARIO-MODULE can be program-
med 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.
Informations available - Setup:
Current Altitude, Min. Altitude, Max. Altitude, Climb-/Sinkrate/s, Climb/-Sinkrate/3s, Climb/-Sinkrate/Min.,
Continous Vario, accuracy: 0.1m
Note:
Any settings you make on the Transmitter or SMART-BOX will be stored in the VARIO-MODULE
only!
Since the VARIO-MODULE can be updated via the USB connection, you always have the latest software
and can utilize future functions or languages. Firmware updates for the VARIO-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, and the adapter lead, Order No. 7168.6A, 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 SENSOR IN THE PLANE
Mount the sensor at an appropriate location in the model. The sensor detects changes in air pressure and
calculates the resulting actual altitude. Therefore, make sure that the sensor is wind-protected in the model
and is not located directly in the
fl
ow of the propeller. Likewise, it must not be mounted on an air-tight place,
such in a sealed radio box. The best way to
fi
x the VARIO-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.
Note:
the accuracy of the sensor also varies with alterations in ambient air pressure, e.g. due to sudden
changes in weather conditions, as well as with changes in air pressure which occur in the course of the day
or during an extended
fl
ight. It is not uncommon for minor
fl
uctuations in air pressure to affect the accuracy
of the sensor to the extent of about 10 to 20 m. These inaccuracies can also be caused by pressure changes
inside the fuselage itself (e.g. high pressure due to the forced propeller air
fl
ow, or air
fl
owing into the model
during a
fl
ight).
