Description
The Graupner transmitters mz-16, mz-32, mc-16 Expert and mc-32
Expert offer the possibility of controlling up to 16 different compo-
nents on the receiver side via the sum signal. The module works
exclusively via the digital switches of the above mentioned transmit-
ters.
The signals of the digital switches on the transmitter touch screen are
transmitted digitally, therefore the components are switched on and
off without delay and interference-free.
Through the suitable cabling of the connection cable the functions
can be powered by a single power source or separately by different
power sources.
(with a common ground, so not electrically isolated)
The compatible GR-12 / GR-16 / GR-24 / GR-32 receivers must be
up-to-date for SumD V3 software.

Safety notes
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 leave the packaging material lying around, this could be
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 driven such a model, then start extra
carefully and make sure to be familiar with the reactions of the
model to the remote control commands. Proceed always respon-
sibly. This also means that you have for your own protection lia-
bility insurance.
Protect all equipment from dust, dirt, moisture. All equipment
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.

The 16 channel digital 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 tres-
passing 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 waranty.
Always proof the correct functions of the module before every use.
Installing the module
The best solution is to fix the module through some double-sided
adhesive tape or hook and loop tape in the model.
Never open the housing and always plug in and out the switched off
components. Thiswillpreventdamagetothe moduleandthe receiver.

10 / 19 3974_MP_V3
Setting the electric connections
The module consumes so little power that you can connect it directly
to the summed signal output (see receiver instructions) with the
included patch cable.
You can connect functions with low power consumption directly to
the switch channel of the module, but only if the total power con-
sumption 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 nec-
essary 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 con-
nected 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 tres-
passing of the limit values can damage the module.

11 / 19
3974_MP_V3
In case of currents higher than 1,0 A connect, as represented, an accessory ground (GND) line to the related
pin A of the channel (as shown in the illustration). Overloading of the tracks on the module is thus prevented.

Note on use of switch relais
In case of use of the Graupner switch relais please pay atten-
tion
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 the polarity inversion is split to
two connectors.
e.g. No. S8189 and 33700.2 combined. Remove remaining
strands according to the scheme.

Programming of receiver and digital switches
For the transmitter to be able to transmit the data correctly, settings
must be made on the transmitter and receiver:
Enter the "Telemetry" menu of the transmitter, open the "Settings &
view" line and move through the touch pads to the "CH OUT TYPE"
line. Here please select the "SUMD3" mode.
This transmission mode is absolutely necessary for the use of the
module! To do this, the receiver must have the latest software ver-
sion. (from V7a..)
To assign the digital switches, call up the menu in the transmitter:
Depending on the transmitter, 16-64 digital switches are available
here.
mz-16: 16 digital switches
mz-32 : 64 difital switches
mc-16 Expert: 16 digital switches
mc-32 Expert: 64 digital switches
1. The switch is activated via menu item "Act". By tapping the plug
symbol is closed. Now it is active.
(As an example, the screenshot above renamed the first two switches.
This name will appear later on the display with the switch symbol.)

Mode of a digital switch
There are 3 modes available:
1. ON/OFF
2. Pulse
3. Flash

3974_MP_V3
After naming the switches and selecting the mode, the switches can
now be linked on the start screen of the transmitter.
If you press the switch, it lights up permanently, flashes briefly or flashes
permanently.
Arranging the digital switches
Procedure:
Touch an empty field on the touch screen for more than 2 seconds.
Select "Digital switch" and press OK.

16 / 19 3974_MP_V3
Then a second window will appear, in which the group and then the
switch itself will be selected:
Select the appropriate switch and press OK.
There are four
switch groups
After confirming with OK the respective switch appe-
ars directly on the touch screen.
Using multiple switch modules
To operate all 64 digital switches, it is possible to connect up to 4
modules. Here the jumpers are used.
Using 1 Module: No Jumper 1. Module Channels 1-16
Using 2 Modules: + 2 poles Jumper right 2. Module Channels 17-32
Using 3 Modules: + 2 poles Jumper left 3. Module Channels 33-48
Using 4 Modules: + 3 poles Jumper 4. Module Channels 49-64
Also only 1 module can be used and this e.g. switches channels 17-32. Important here is only the plug
position of the jumpers.
Modules can also be connected in parallel, ie one in the cab, the other in the trailer or semi-trailer.
Both modules, for example, without jumpers for channels 1-16. So these are switched simultaneously.
As an example, the turn signals, hazard lights, headlights on the tractor and the semi-trailer.
