NOTE

The technical data of the optional receiver are available in the man­ual included in the receiver package content.

Graupner transmitters mc-16, mc-20, mc-26, mc-28 and mc-32
offer the possibility to connect up to 16 different functions to one
transmitter channel. Older MHz sets (4014, 6014 and similar)
require a decoder in the transmitter (old Graupner No. 4108)

In HoTT systems it is just required to activate one of the two
available muctichannels. In the old transmitter no other adjust­ment is required.

The switch settings in the transmitter are transmitted in data
packets, for this reason the functions can be activated and
deactivated with a little delay.

Through the suitable cabling of the connection cable the func­tions can be powered by a single power source or separately by
different power sources.

Particularly those which are additionally marked with the CAU-
TION or WARNING. The signal word WARNING indicates the poten­tial for serious injury, the signal word CAUTION indicates possibil-
ity of lighter injuries.

The signal word Note indicates potential malfunctions.

Attention indicates potential damages to objects.

General

These safety instructions are intended not only to protect your

own and other people’s safety, but also to protect the product.
Therefore please read this section very carefully before using the
product!

 Do not carelessly leave the packaging material lying around,

since it might become a dangerous toy for children.

 Persons, including children, with reduced physical, sensory

or mental capabilities, or lack of experience or knowledge,
or not capable to use safely the transmitter must not use the
transmitter without supervision or instruction by a responsi­ble person.

 Operation and use of radio-controlled models needs to be

learned! If you have never operated a model of this type
before, start carefully and make yourself familiar with the
model's reactions to the remote control commands. Pro­ceed always responsibly. This also means that you have for
your own protection liability insurance.

 Protect all equipment from dust, dirt, moisture. All equip-

ment must be protected from vibration as well as excessive
heat or cold. The models may only be operated remotely in
normal outside temperatures such as from -10°C to +55°C.

Installing the Module

The 16 channel switch module has been developed for use in
RC models and it should only be used for the previewed scope.

Please note that the module should only be used within the indi­cated limit values (see technical data).

Use and store the unit in a dry environment only.

Every mechanical or electric modification of the module or the
trespassing of the indicated limit values brings immediately to
loss of all dispute rights against the producer, including the war­ranty service.

Any damage on the warranty seal on the back part of the mod­ule also brings to an immediate loss of warranty.

Always proof the correct functions of the module before every
use.

The best solution is to fix the module through some double-sided
adhesive tape or hook and loop tape in the model. Alternatively
you can also screw the plate with the included spacers, through
the four fix holes. While tightening the screws pay attention that
the plate should not be bent and that the lower part of the plate
does not touch any other construction component (short-circuit
risk).

For the holes dimensions please refer to the following illustration.

According to the used screw type, the screws can touch the
ground (GND) of the plate and establish an unwanted connec­tion. In case of installation in a conducting surface, please pay
particularly attention because of the risk of short-circuits.

Setting the electric connections

The module consumes so few current that you can connect it
through the included patch cable directly to the multichannel
output of the receiver.

You can connect functions with low power consumption directly
to the switch channel of the module, but only if the total power
consumption of all the connected functions is lower than 1,0 A
and only if the receiver voltage is enough (see switch plan).

To allow an as universal as possible use of the module, the mod­ule switches the ground (GND). This has the positive aspect that
if necessary each function can be powered by a different source.

To allow this it is important that the minus pole of each power
source, e.g. batteries, is connected to the other ones.

The functions will then be connected securely with the plus pole
to the related battery and the minus pole of the function will be
connected to the switch module.

In case of low currents the ground connection through the patch
cable of the receiver is enough, on the other hand if the current
is higher you should connect each ground separately (see switch
plan).

Please note that inductive or capacitive functions ( as relais,
motors or capacitors, etc...) during the switch-on phase can
require much higher current than the one needed during the nor­mal use. A trespassing of the limit values can damage the mod­ule.

Note on use of switch relais

In case of use of the Graupner switch relais please pay
attention to the inverted polarity!

See connection scheme on the left.

In case of use of a No.4159.3 it is necessary to create
a connection cable because this polarity inversion is
split to two connectors.
e.g. No. S8189 and 33700.2 combined. Remaining
strands have to be removed according to the scheme.

Programming the switch assignment of HoTT transmitter

To allow the transmitter to transmit the data correctly, you still
have to set one option in your transmitter.
Enter the "Telemetry" menu, open the "Settings & view" line and
move through the touch pads to the "CH OUT TYPE" line. Here
please select the "SAME" mode!

This mode is absolutely necessary for the use of the multiswitch­module!!

After having installed and connected all the required switches,
now you have to assign the switches and to program correctly
the multichannel functions.

Search in the menu the voice "Multichannel".

Touch shortly the "Set" button to open the selection menu.

Here you have two multichannels available, select one channel.
Move to the desired channel and select it through the "Set" but­ton. So you can activate (ACT) or deactivate (INH) the channel.

13 / 19

Programming the switch assignment of HoTT transmitter

Here activate both multichannels as multichannel, while the sec­ond multichannel has been assigned to the channel 6, with
which we will proceed in the description.

Now move the cursor to the right field, select the "MULTICH
8CH" and confirm it through the "SET" button.

14 / 19

Then you are in this menu. Move the cursor to the red marked
area and push the "SET" button.

3972_MP_V1

Programming the switch assignment of HoTT transmitter

!!!

Soon after you will have to actuate the desired switch.

After the actuation it looks like this, even if here you can see
soon the switch number.

Please use the same process to assign the other switches in the
transmitter.

Please note that always only one of the two switch setting pro
input can be transmitted! In case of actuation of more than one
switch it can bring to a function error.
For this reason the switches with 3 functions / switch positions
have to be connected always to a channel!

The "Offset" should not be changed, e.g. bring it to "0", so as
the travel should be to 100%!

If you open the "SERVO VIEW" menu, the related active multi­channels flicker to give a notice of this optional setting - it is
totally normal.

For information about other parameters of the transmitter refer
to the manual of your transmitter.

3972_MP_V1

15 / 19

Programming the switch assignment of Graupner/JR transmitter

Older MHz transmitters (4014, 6014 etc.) require the control or
decoder module (old Graupner No. 4108). A switch assigna­tion, as required for the HoTT transmitters, is here not neces­sary.
Accurate notes for the function are indicated in the respective
transmitter manual.

Memory function

In the transmitter are included up to 8 switches, accordingly you
can activate only 8 functions at the same time. Through the
memory function you can also change it.

Therefore one switch channel is brought in the memory func­tion, which by each switching activates or deactivates the chan­nel. You can bring every single channel individually in the mem­ory function. If you have brought at least 8 channels in this
function, you will be able to activate and deactivate also 16
functions.

Switching on the memory function

Switch as usual the model and the transmitter on, move all the
switches on the transmitter to the middle or Off position and pro­ceed as follows:

• Push and hold the T1 button on the plate

• Activate (ON) the switch that you want to bring in the mem­ory function

• Release the T1 button

That was all. Of course you can bring also several switches in
the memory function.

16 / 19

3972_MP_V1

Memory function deactivation

!

You can also deactivate the memory function in the same way
as you have activated it.
Switch as usual the model and the transmitter on and proceed
as follows:

• Activate (ON) the switch that you want to remove from the
memory function

• Push and hold the T1 SET button on the plate

• Deactivate (OFF) the switch in the transmitter.

• Release then the T1 SET button

That was all. Of course you can remove also several switches
from the memory function.

The only one difference between activating and deactivating the
memory function is the position of the switch in the transmitter
in the moment in which you push the T1 button on the plate and
which position has the switch after the release of the T1 SET
button.
From OFF to ON activates the memory function, from ON to OFF
deactivates the memory function.

Fail-Safe function

In case of malfunction of the receiver or in case of loss of the
receiver impulse you can program the multiswitch module so
that all the switch channels are automatically deactivated.
Therefore connect the X1-9A with X1-9B and set also your
transmitter or receiver in this mode. Only with active Fail-Safe
function the module can deactivate the functions.
The mode for the Fail-Safe function is requested when the mod­ule is switched on, changes during the use of the module are
not saved.

3972_MP_V1

Validating the transmission

The switch settings are serially requested in the transmitter and
transmitted. First when from the switch module has been rec­ognized the complete data packet, the outputs switch accord­ing to the switch settings of the transmitter.
Nevertheless interference impulses can lead to error switch pro­cesses.
To make the switch processes even safer, there is the possibility
in the 16 channel switch module, to compare the related switch
settings from two sequential data packets. Only if the switch set­tings from two different but consequential data packets match
the channel will be activated.
Through this validation you can have an almost 100% safe
switch of the channel but it will also be slower.
You can activate this function by connecting the X1-9B with
X1-9C.
You can activate this function in parallel with the Fail-Safe func­tion, all you have to do is to connect all the X1-9 pins to each
other.

Firmware update

The 16 channel switch module has been specifically been devel­oped for Graupner HoTT 2,4 GHz transmission systems and
needs
no other settings. If you have any question or problem during
the use, please contact us under Hotline service@graupner.
