Declaration of conformity
Kingbus Central Module
Graupner/SJ declares that the product is conform to EU norms.
WEEE-Reg.-Nr.: DE 42466037
Product description
The Kingbus is a two-wire bus system that allows multiple light fun-
ctions through just two wires. The power supply of the light modu-
les is also ensured via these two wires.
The central module receives the desired lighting functions, evalua-
tes them and sends them via the Kingbus to the light modules.
This item has been tested in accordance with EU directives and
complies with the legal requirements.

Supply voltage Please note that the KBZM may only be supplied with
filtered DC voltage from a power supply unit or with a
battery / rechargeable battery!
Connection terminals
The spring-loaded terminals can be operated with the supplied
needle.
Insert the needle into the rectangular opening and press down
approx. 5mm
The clamp opens
Slide the stripped cable (approx. 5mm) into the round hole until
it stops
Carefully remove the pin-> terminal closes
Check cable for tightness
When not in use, put the needle back in the housing! TIP: Best
suitable flexible, twisted, non-tinned cables from 0.08mm² to
1.0mm²!
Power supply
Connect a voltage source of 7- 12 V to Bat.Plus and ground (GND).
The two inputs (plus and ground) are each internally "jumpered" and
can be used for other purposes (e.g., RKLs to Out2)
Servo inputs
In order to be able to determine the direction and the change in
direction, the signals of the speed controller and the steering servo
are required. Use the supplied servo patch cables to connect the
central module (Speed IN and Steering IN) to the corresponding out-
puts on the receiver.
Speed controller and steering servo are now connected to the KBCM!
(Speed and Steering OUT)
Another module can be connected to the third output (eg audible
reverse warning) The central module acts as a Y-cable here.
Connection options
Single inputs: If you have a speed controller with cruise control fun-
ction (K40, M24, K20, .. from Servonaut), you can continue to use it.
The reversing lights and brake light are connected via the two "Back"
and "Brake" terminals. The remaining lighting functions can still be
switched via the external lighting system. To do this, connect the
light outputs of your light module / speed controller to the two
inputs on the KBCM. To each input is assigned a light function!
IMPORTANT! If the ground of the light module and the Kingbus cen-
tral module are not the same (different batteries), a ground connec-

12 / 16 3975_MP_V1
tion must be made. For this purpose, the ground terminals GND can
be used.
Light modules
Install your light modules in the model and connect them to one of
the three Kingbus outputs on the KBCM. On a bus it does not matter
how and where you connect which module! The extension cable is
suitable for wiring the rear lights. The system can be expanded with
the various distributors and extension cables.
First use
After everything is properly connected and wired, you can turn the
power on. The red and yellow LEDs should be constantly lit. If this is
not the case, check the wiring for any short circuits.
Adjustment and servo reverse
For the very first commissioning, you must initialize the central
module. The sticks of the remote control must be in the middle posi-
tion! Press the white Prog button for more than 2 seconds until the
yellow LED flashes once each second.
If you have a Kingpad, press each key once in a row. (See also King-
pad's manual!) As a confirmation of a recognized key, the yellow LED
remains off also if pushed. After releasing it flashes again!
After the last key, the central module automatically returns from
programming mode to normal mode.
If you do not have a Kingpad, simply press the Prog button again and
the module will return to normal mode. The zero positions for dri-
ving and steering are thus programmed.
If the drive and steering movements do not match the lighting (turn
signal and reversing light), the channels can be reversed using the
Config switches 1 and 2.
Outputs
The outputs Out1 and Out2 can be used to control additional func-
tions. The outputs switch to ground when activated.

Demo mode
The Kingbus central module can play a demonstration of the light
controls by briefly tapping the Prog button (less than a second). This
can be used for example to make the model more visible at exhibi-
tions. Remote control is not necessary for this mode! Press the Prog
button again briefly to stop the demo mode.

Technical data
Operating voltage: 5 Volt via Kingbus
Connection cable: 150mm, Kingbus connector
Dimensions: 27 x 15 x 8mm
Note
The Uni-Mod is equipped with a spring-loaded terminal. The proce-
dure for connecting the cables is described below:
Insert the connection pin into the rectangular opening (notice-
able resistance must be overcome, terminal opens)
Insert the cable into the round hole until it stops
Carefully remove the pin
Check cable for tightness

Legend universal modules
The circular dot next to each icon indicates the color of the LED to
be connected. It can be connected per output 1 LED directly (without
series resistor)!
If several LEDs are connected to a normal output, they will not light
up so much. The Uni-Mod does not take any damage!
HC outputs have no resistor! This must be calculated accordingly for
5Volt operating voltage!
