GRAUPNER mx-20 Hott, Programming Manual

Page: 71 / 296

71 Detail program description - Base setup model
Important notice:
By using the
mx-20
HoTT transmitter's "Tx. output
swap " option the transmitter's 12 control functions
can be freely swapped in a similar manner or multiple
outputs can be assigned to the same control function.
To avoid confusion, it is strongly recommended that only
one of these two options is used.
Channel assignment on the second receiver
As already mentioned, the "Receiver channel mapping"
option can be used to freely distribute the
mx-20
HoTT transmitter's 12 control channels across two
receivers, whereby the numbering sequence of outputs
(servo connections) begun in the "BD1" column for
bound "receiver 1" will be continued. For example, if
"receiver 1" has enough connectors for 12 servos then
the numbering of outputs in the "BD2" column (for the
second bound receiver) will begin with 13.

After selection of the desired output with the arrow
keys of the left and right touch pad, the corresponding
input fi eld will be framed. Press the center
SET button
in the right touch pad The current setting is displayed
in inverse video. Now select the desired input channel
with the arrow keys of the right touch pad. For example,
suitable to the above rudder example.

Notice:
The number of lines available (outputs) corresponds to
the maximum number of servos which can be connected
to receiver 2 and their numbering is dependent on the
maximum number of servos which can be connected to
receiver 1.
RF transmit
This menu line provides an option for manually
switching the transmitter's RF transmission on and off
to specifi c models while the transmitter is in operation.
For example, to save power while a model is being
programmed.
If this line option was set to OFF, it
will be canceled (i.e. set to ON) the next time the
transmitter is switched on.
If necessary, use the

arrow keys of the left or right
touch pad to reach the "RF transmit" line then activate
the option with by briefl y pressing the center
SET button
in the right touch pad

The right arrow keys can now be used to choose
between OFF and ON . Again pressing the center SET
button in the right touch pad will complete the entry.
Range test
The built-in range test reduces transmission power to an
extent that a function test can be carried out even within
a distance of up to about 50 m.
Perform the range test on the
Graupner HoTT system
according to the following instructions. If necessary,
have someone assist you in carrying out the range test.
Preferably the receiver already bound to the 1.
transmitter should be installed into the model in its
intended position.
Switch remote control on and wait for the receiver's
2.
green LED to light up. Now servo movements can be
observed.
Place the model on a level surface (pavement,
3.
low-cut grass or bare ground) such that receiver
antennas are at least 15 cm above ground level. It
may be necessary to put something under the model
to raise it up enough for this.
Hold the transmitter at hip level and at some distance
4.
from one's body. Do not point the antenna directly at
the model but rather turn and/or kink the antenna's
end so that it is oriented vertically during the test.
If necessary, use the
5.

arrow keys of the left or
right touch pad to reach the "RF Range Test" line in
the menu then start range test mode by pressing the
center
SET button in the right touch pad.
