•Turn on the radio, the head lights remain on and you hear the horn sound.
•At this point you can activate certain functions such as:
High beam lights, fog lights, indicators, emergency lights, horn 1 & 2, coupling / uncoupling
trailers.
•Start the engine of the truck (right stick diagonally lower left for 5 seconds) and wait for the
engine to finish starting up and starts idling.
•Engage a gear and bring the left stick forward or backward to move, make sure the truck is
moving in the right direction.
•Try to steer right and left and check that the wheels are moving in the right direction, check
also the activation of turning indicator lights.
NOTE
If some of the movements are reversed compared to the command you need to reverse its own
channel on the radio, or change the parameter for the channel in the file "IBU2_TR.ini" in the root
of the microSD board inserted in IBU2 (see chapter 7 below).

Additional controls availa le from the radio controller

•Horn 2 right stick down (about 25% of the movement) to play the sound effect of the horn 2
•Revving the engine with out moving truck, right stick up (about a 25% of the movement
useful) to play the sound effect of the engine revving.
•Air exhaust from the air rake reservoir right stick down (about 25% of the movement useful)
to play the sound effect of the exhaust air

6CHANGING THE SOUNDS
On the supplied microSD are provided customized sound effects for a several number of trucks.
Note: To fully enjoy the sound quality it is recommended to use the original Tamiya
tm
speaker's or
a speaker of good quality available from your local dealer.
To select the set of sounds appropriate for the truck on which is installed the IBU2, do the
following:
1. With power OFF, press lightly on the microSD inserted under the IBU2 to release the microSD
memory card (NOTE: DO NOT PULL THE MICROSD TO UNLOCK !!!), pull it out and insert into a
memory card reader (not supplied) on your PC, MAC.
2. Access the media and browse its contents.
3. In the root of the media are the files used by the sound module of IBU2.
Each wave file is associated with a different sound effect according to the correspondence
set in the file "IBU2_TR.INI":
Varia le in the file IBU2_TR.ini Es. Audio file Corresponding effect
Engine Cold ON estartc.wav Starting a cold engine
Engine Warm ON estartw.wav Starting the engine hot
Engine Stop estop.wav Engine stop
Engine Idle eidle.wav Engine idling
Engine Step 1 es01.wav Motor Ramp 1
Engine Step 2 es02.wav Motor Ramp 2
...
Engine Step XX esXX.wav Motor Ramp XX
Revup revup.wav acceleration
Revdw revdw.wav deceleration
Air last1 air st1.wav 1 air vent
Air last2 air st2.wav Air vent 2
Air last3 air st3.wav Air vent 3

Shift1 horn1.wav Clacson1
Shift2 horn2.wav Clacson2
Turn1 turn1.wav indicator 1
Turn2 turn2.wav indicator 2

. To choose a different truck set for your truck simply enter into its subfolder (e.g. "Mack") and
copy all the files in the root of the microSD, overwriting the existing ones. Check the name
matching the audio samples with the associated tags in the file IBU2_TR.INI.
5. Remove the microSD from the PC/MAC adapter and put it back into the IBU2 socket until it
clicks, turn on your truck and try new sounds included.
6. New sound sets when produced will be available to download from http://www.ibu-
electronics.com/downloads_9.html
You can also create your own sounds by replacing the sounds provided by converting a sound
effect or music from any format (WAV, MP3) in WAV format, mono, 22050 Hz, 8 bits. Each sample
must not have a size greater than 1 Mb or its reproduction will be truncated.
The names of the * .wav files are not important, as long as the file is reported IBU2.ini proper
correspondence between each file and its sound effect, and provided they are not longer than 8
characters (plus the extension ".wav") and do not contain spaces or periods.
Example
"Abcd_defg.wav" Not good (9 characters);
"Abcdefghi.wav" Okay (8 characters);
"Ab cd.wav" Not good (5 characters, but there is a space);
"Ab.cd.wav" Not good (there is a point in the middle of the name).
Note: some audio editing software is not able to successfully convert the audio in this format, or
add data that can not be read by IBU2: if you have problems in the reproduction of its
samples, please contact the manufacturer.
Also avoid reformat the microSD provided ecause some operating systems do not
properly format the media.

7CONFIGURATION SETTINGS "IBU2_TR.INI"
In addition to the associations of the sound effects with the corresponding wave file, into the text
file IBU2_TR.INI there are other variables that allow you to customize certain features of your IBU2
Truck.
Configuring the reverse channel radio
Each line refers to a specific channel receiver, this function is used, if you are using an older radio
(without memory), to avoid having to set (if necessary) the reverse channels depending on the
truck that are using
RadioCH1InverseCmd = FALSE; TRUE / FALSE
RadioCH2InverseCmd = FALSE; TRUE / FALSE
RadioCH3InverseCmd = FALSE; TRUE / FALSE
RadioCH InverseCmd = FALSE; TRUE / FALSE
In this example, all channels have value FALSE this means that no channel is applied on the
inversion, or the commands that arrive from the transmitter are reported to the decoding circuit
so as sent.
Configuring the reverse servo
If needed, you can reverse the direction of rotation of the servos, each line is related to a specific
channel, and this function is used as different manufactured servos turn in opperstie direct. This
will be truck specific.
The line:
SteerInverseCmd = FALSE; TRUE / FALSE allows you to reverse the steering control
The line:
TrailInverseCmd = FALSE;TRUE / FALSE allows to invert the command of latch/unlatch the trailer
The line:
ShiftInverseCmd = FALSE; TRUE / FALSE allows you to reverse the command of the gear shift
In this example, all channels have value FALSE this means that no channel is applied on the
inversion.
Configuring the front and rear lights
The parameter is used to configure the state of the headlights at truck power on
HeadlightInitialStatus = 1; [0 OFF - 1 ON]
In this case, the lights will be turned on at power on, by entering the value 0 (zero) the truck will
start with the lights off.
(The lights can be turned on or off even from the transmitter, see chapter 5 Controls)

Configuration of the rear lights and brake lights
The rear lights and the stop, (typically two LEDs) are powered by the same output, the output is
modulated to obtain a low intensity for the tail lights, the parameter:
TailLightIntensity = 50; [1..50]%
Allows you to adjust the brightness of the rear lights, a lower value will decrease and vice versa a
highest increase.
Since braking output is modulated at 50% if you use a value very close to this for the sidelights the
braking effect will be barely visible.
The following parameter allows you to adjust the length of time of the brake lights stay lit when
you make a brake:
BrakeDuration = 500; [100..5000] mSec
The range of values allowed is from 100 to 5000 milliseconds.
Configuring the maximum current supplied to the motor
Parameter: CurrentMotorTreshold = 10; [1..15]
Adjusts the threshold of over current monitoring protection.
The default value is 10 Amperes, it is possible in case of use of particular reducers or very heavy
truck to increase up to a maximum of 15 Ampere the current supplied to the motor.
Configuration of the power supplied to the motor
The parameter: PowerMotorScale = 100; [1..100]%
Allows to adjust the overall power delivered to the engine during running, this function calibrates
accurately the movement speed to approach to the dynamics of the real truck, a lower value will
decrease and vice versa a higher increase.
Configuration of the vibration of the cab of the truck
The parameters: MinPwmMot = 25; [0..100] and MaxPwmMot = 30; [0 ... 100]
Allow to set the minimum and the maximum speed of the vibration unit, from 1% to 100%
To turn off simply enter the value 0 in both parameters.
Configuring the maximum reverse speed
The parameter: ReverseSpeed = 50; [1 ... 100]%
Used to limit the speed during reverse.
To have same speed backwards as forwards set parameter to 100

8 TROUBLE SHOOTING
Nr. ANOMALY POSSIBLE SOLUTION
1 I turn on the truck but
nothing happens.
- The battery is exhausted: recharge
- The power connections are broken or incorrect: check
the connections from the battery
2 The engine does not start
when I hold stick down left.
- Check that the turning indicators flash, high beam and
fog lights operate in the right direction with respect to
the control stick, if not servo channels and/or reverse
settings need changing.
If correct check battery voltage, engine won’t start on a
low battery.
3 I turn on the truck but the
headlights continues to flash
-No valid RX signals received : check the connections
between the IBU2 truck and receiver
4 The turning indicators are in
opposite direction
- Reverse the channel (Ch ) in the transmitter or in the
settings file IBU2.ini
5 I have no sound - Ensure that the volume is turned up
- Ensure that the speaker is connected
- Ensure the microSD card is plugging in correctly
- Ensure that the samples are all present in the microSD
card, the correct size and properly associated to its
function in the file IBU2.ini
6 The truck moves or steers
the opposite direction
compared to controls
- Reverse the acceleration channel (Ch1) and / or steering
(Ch2) on the transmitter or in the settings file
IBU2_TR.ini
7 The servo(s) does not move - Check that the servo connector is inserted with the
correct orientation
- Check that the servo can move freely in the direction
8 The card overheats or a
burning smell
- Disconnect the battery immediately / off the wagon:
there must be some short circuit in your links!
