r/c tank Multifunctional module
The IBU3 module is a totally new board, based on experiences with IBU2, it offers superior performance combined with
flexibility and ease of use.
The IBU3 module completely replaces the electronics present in the RC Tank, allowing to fight according to the IR Tamiya
standards, customize all the sound effects and use a proportional radio from 4 to 8 channels (AM, FM, or 2.4 GHz) for full
tank control.

IBU3 Module CONNECTIONS
Connect receiver channels receiver as shown in the figure, the polarity of the signal
(orange) is turned towards the outer edge of the module IBU3
(For clarity only the first channel is connected)
Connect the servos as shown in the figure, the polarity of the signal
(orange) is facing the receiver connector
(For clarity only one servo is connected)

Connect the USB cable (supplied in the package) as
shown in the figure.
If you intend to use the volume pot remove the AB bridge and connect the cable to
related connector.
If using the remote volume control (using one radio channel, see the section in IBU3
Configurator) you can omit the volume control, in this case the AB bridge must be
inserted.
Connect the speaker to the speaker connector, it is recommended, in order to avoid
sound distortion, to use a good quality speaker, not less than 8 watts with an impedance
of 4 or 8 ohms.

 MG2
The connector allows you to connect a LED to simulate the flash of the 2nd MG barrel (which is selectable by a radio
channel, see the section IBU3 Configurator). The light output is synchronized to the reproduced audio sample.
 Flash connector
The IBU3 module allows you to connect a high-brightness LED flash to simulate the gun muzzle flash.
Connect this output to a high-brightness LEDs.
 Brake connector
The module allows you to connect two leds (in parallel) to be used as taillights and simulating the brake lights (if the
braking simulation function has been activated, see the section in section Configurator IBU3).
 SM R connector
The IBU3 module allow to use a smoke unit such as TARR Smoker or similar who have cables for the separate heating
resistor. Connect this output to these cables. (Maximum relay load = 3 amps)
 SM P connector
Output proportional to motor speed, connect to this output a standard HL/Taigen smoke generators, or the fan of the
TARR unit

 Tamiya TBU connectors
The IBU3 module allows you to use Tamiya IR unit without changes.
Connect the IR receiver cable to the receiver connector and the LED to LED connector
 IR Port Connector
Connect the IR cable (Heng Long/Taigen) to this connector
 Range jumper
If you have selected (in the Misc Configuration page of the IBU Configurator) the Recovery tank type you must
remove this jumper to reduce the range of the IR beam to about 1 meter.
 Flasher connector
If you are not using an IR receiver with integrated LEDs (Tamiya or Impact) you can connect one or more LEDs (in
series / parallel) to have a visual feedback of the standard battle signals (hit, wagon).
If the Extended Signalling (on the Misc Configuration page of the IBU Configurator) are enabled you will be able to
view additional status messages
  One Flash = inertia and smoke generator on / off
  two flashes = battery warning
  three flashes = overcurrent warning
 Four Flashes = lack of radio signals
 five flashes = overtemperature warning

Hardware built in protections
The IBU3 Module is equipped with internal protections.
The 16 Ampere 5x20 Fast Action Fuse (which is the only part serviceable by the user) protects the powertrain
The PTC Resettable fuse (service fuse) protects the all the electronics, in case short circuit or wrong connections this fuse will disconnect
the main supply coming from battery. After a short time this device will reset itself automatically and the electronics will be supplied
again. If the fuse act again disconnect all the cables from the module (except for the battery supply) and check carefully the wirings.
