A quick start
IMPORTANT! Please note that this quick start section should only be used to test
the Intellibox. It is absolutly necessary to read the whole manual in
order to understand and use all Intellibox features.
You need a transformer with 16 V AC output voltage and a minimum
output power of 52 VA. Use wires with max. diameter 1.1 mm
(cross sectional area = 1 mm2, 18AWG). The 16V AC voltage from
the transformer and the two poles of the track are connected to the
clamps of plug 1 on the backside of the Intellibox.

• One out of two rails to clamp 3 (red Märklin cable)
• The other rail to clamp 4 (brown Märklin cable)
• The AC voltage to clamps 5 and 6
Read this in case... you are using a DCC/NMRA format and most of your decoders for
locos, turnouts and switching devices conform to the DCC/NMRA
data format. Please make the following connections to plug #1 (do
not insert the plug in socket #1 of the Intellibox):
• The middle rail to clamp 3 (red Märklin cable)
• The two rails (body of the track) to clamp 4
(brown Märklin cable)
• The AC voltage to clamps 5 and 6
Read this in case... you are using the Märklin Digital System ("Motorola" or "AC" for-
mat) and most of your decoders for locos, turnouts and switching
devices conform to the Motorola data format. Please make the fol-
lowing connections to plug #1 (do not insert the plug in socket #1 of
the Intellibox):
Connect now plug #1 to the Intellibox. Before doing this, please
verify carefully that the wires from the transformer have not been
swapped with those from the track, or that short-circuits did not
occur among the various wires of the connector!! A short-circuit
between the transformer and the track could destroy the output
stage of the Intellibox!
As soon as the plug has been inserted in socket #1 of the Intellibox
(the transformer must be connected to the AC main line), the dis-

1.2 Connecting the clamp plugs
To connect the transformer, the nor-
mal track and the programming
track as well as the Lenz booster,
two clamp plugs are supplied with
the Intellibox. Use a work bench or
similar surface, when conntecting
the cables to the clamps.
The designations of the clamps are
shown in Figure 1.21. To mount a wire onto the clamp plug,
remove approx. 6mm of the wire in-
sulation at the wire end. Use a small
screwdriver (2.5mm) and insert it into
the upper slot of the plug. A gentle
downward push on the screwdriver
opens the cage clamp of the plug.
Insert the un-insulated wire end into
the clamp. After removing the screw-
driver out of the upper slot of the plug, the wire is secured. As
shown in the figure, it is recommended to insert the wire in a slightly
bent position.

Automatic set-up at power on
Should you keep a key pressed during the Intellibox power on, you
will force the Intellibox to perform special actions (automatic set-
up).
[menu] forces the Intellibox keyboard to enter the “upload” mode
(software update). This action can also be accomplished auto-
matically by the PC-program which updates the Intellibox soft-
ware.
[mode] test mode (keypad, LCD display, LED‘s and rotary encod-
ers)
[+] restores LCD contrast and backlight to their default values
(i.e. the production values - as set in the Special Options).
[C] allows you to define and interactively store the LCD display
contrast. Use the [!] key to decrease and the ["] key to increase
the contrast voltage. Store with [8].
[0] forces the keyboard program to be activated, even if checksum
not Ok or some other kind of “error” in the flash-ROM

Use the basic settings of the Intellibox (section 5.8) to choose how
the Intellibox handles the PT. You can choose either "only program-
ming track" or "automatic". The latter means that you can use part
of your normal layout track (but insulated on both rails). The advan-
tage in this case is that you can drive a loco into the PT, enter the
programming mode, change and read configuration variables and
finally steer the loco out of the PT. The changeover between PT and
normal track is done by a relais in the Intellibox.
In case of a short-circuit between the normal track and the pro-
gramming track the Intellibox will display an error message.
A short circuit also occurs when the two terminals of the Program-
ming Track are erroneously swapped.
It is preferable that a newly installed decoder is first connected to
the PT (a low-current, low-energy track) instead of the normal track,
in order to check for the correctness of the installation. In fact, in
case of wrong connections, it is less likely to produce a damage on
the decoder. For this reason we suggest installers of decoders to
choose the option "only programming track" in the basic settings of
the Intellibox.
The programming track
The programming track (PT) is a special track for programming
and reading out the configuration variables of loco decoders.
Both rails of the PT must be isolated from the normal track. This
must also be true for 3-rails Märklin tracks, where the two lateral
rails must also be isolated! With “M” tracks this is a really difficoult
task (insulation of the ballast)! During programming, the isolation
gaps must not be crossed or bridged by locomotives or boogies,
being this prejudicial to a good electrical insulation.
The PT is connected to clamp 1 (brown) and 2 (red) of plug #1.

The transformer
In order to obtain a troublefree operaton of the Intellibox please use
a transformer of min. 52 VA output power. The maximum output AC
r.m.s. voltage from the transformer should not exceed 18V.
The transformer must be connected to clamps 5 and 6 (brown and
yellow, respectively).
Please verify carefully that the wires from the transformer have not
been swapped with those from the track, or that short-circuits did
not occur among the various wires of the connector!! A short-circuit
between the transformer and the track could destroy the output
stage of the Intellibox!
The track
The track must be connected to clamps 3 and 4 of plug #1. For 2-
rails tracks, follow this example:
For 3-rails tracks, clamp 4 is the ground potential of the digital
voltage and corresponds to the brown wire of a Märklin digital sys-
tem (external rails). Clamp 3 corresponds to the red wire and must
be connected to the central rail.

1.7 Connecting the s88 feedback modules
Feedback modules are used for detecting the presence of trains
on several track sections and for automatic train control. All feed-
back modules which are compatible with the Märklin s88 (6088)
can be connected here. Theflat cable deliveredwith
the feedback modules
must be connected be-
tween the Intellibox con-
nector #4 and the first feed-
back module. Both ends of the flat cable, in the Intellibox and in the
feedback module, must run downwards.
If several feedback module are to be connected to the Intellibox, the
enclosed special cables must be used to connect the output of one
module to the input of the next module. This is shown in Figure
1.72 (see also the operating manual of the feedback module).

1.6 Connecting a LocoNet Booster
LocoNet Boosters (optoisolated only!) must be connected to con-
nector #6 on the rear of the Intellibox using a 6-poles Western
cable.
These boosters are not able to transmit a short-circuit signal to the
Intellibox. These boosters are usually protected by their own short-
circuit protection.
1.4 Connecting a DCC booster
In principle, all optoisolated DCC Booster can be connected to
plug #2. DCC Boosters are not able to output a Selectrix signal.
Lenz Booster
These Boosters can directly be connected to the Intellibox. The
signal lines C and D and the short signal line E must be connected
to the 3 pole clamp plug as shown in the picture.
Märklin- and Arnold Digital= Booster
Märklin Digital= Boosters (6016) and Arnold Digital= Boosters
(86015) are optoisolated. Therefore they can be connected to con-
nector #2, but only using the Uhlenbrock/Modeltreno adapter no.
693.
Other DCC boosters
Only optoisolated DCC Boosters can be connected to the Intelli-
box!
Usually, DCC boosters have only two wires. These wires should
be connected to plug #2, clamps 1 and 2 of the Intellibox.
These boosters are not able to transmit a short-circuit signal to the
Intellibox. These boosters are usually protected by their own short-
circuit protection.

1.5 Connecting a Märklin Booster
Connector #5 is designed for Märklin Boosters (6017 and 6015)
and all Märklin-Motorola compatible Boosters (including Modeltreno
#66007).
The flat cable delivered with the Märklin Booster must be tied at
connector #5 of the Intellibox, running upwards. On the Booster side
(see also the operating manual of the Booster) this cable must run
downwards from the model Märklin 6015 and upwards from the
model Märklin 6017, as shown in Figure 1.51.
The SO #901 has to be changed to a value slightly higher than the
factory default one (e.g. from 1 to, say, 3) in order make it possible
to control DCC locomotives on layout sections supplied through a
Maerklin Booster 6015 or 6017.

1.9 Connecting a computer
The Intellibox can be connected to the serial interface of the com-
puter. Every IBM compatible PC or Laptop and every Apple Macin-
tosh feature a serial interface. Sometimes it is called ComPort,
V.24-Interface or RS232-Interface.
The Intellibox can be connected to the computer using a normal
Com Port cable as in the case of the connection between a compu-
ter modem and the computer (art. #691). Should you like to build
your own cable, please use the connections shown in Figure 1.91(a)
in case of a computer with a 9-pole serial interface, or in Figure
1.91(b) in case of a computer with a 25-pole plug.
The factory settings configure the Intellibox for an IBM compatible
PC and for using only the syntax of the Märklin 6050/6051 Interface.
The default Intellibox serial interface settings are: 8 data bits, 2
stop bits, baud rate 2400 bit/s, no parity, CTS line used, DTR line
not used. Changes to this configuration could be made using the
basic settings menu (see section 5.9)

1.8 Connecting the Lokmaus
Both Roco and LGB Lokmaus can be used. They must be con-
nected to connector #3 of the Intellibox.
Eight different locos can be controlled with one Lokmaus. The loco
can be selected using the 8-positions slider of the Lokmaus. Up to
eight Lokmaus could be used at the same time with the Intellibox.
With the factory setting of the Intellibox the positions 1-8 of selec-
tion switch correspond to the loco addresses 1-8.
The assignment of loco addresses to the position of the selection
switch can easily be changed using the basic settings menu of the
Intellibox (see also section 5.11).
Connecting more than one Lokmaus
Several Lokmaus could be connected to the Intellibox using a Y-
shaped cable (ROCO 10755).
The following points must be taken into account when using a
Lokmaus:
• Due to the Lokmaus characteristics, the Power on/off button can
only be pressed once every 5 seconds.
• The light and the horn button can only be pressed every second.
• The light button of the Lokmaus corresponds to the [functon]/[off]
buttons of the Intellibox.
• The horn button corresponds to the [f1] button of the Intellibox.
• Should several Lokmaus try to control the same loco using the
same position of the selection switch, then only one of them (the
first one) will actually control that loco.
• A loco which is controlled by a Lokmaus cannot be controlled by a
second Lokmaus.
Only Lokmaus compatible devices could be plugged into this con-
nector. Do not plug any X-Bus device in it!

Available addresses in C80, C80f ed Infra-Control 80f units
When you plug a Control 80 on the right side of the Intellibox, you
are obviously allowed to control the locomotive addresses from 1
to 80.
However, in the case of a Control 80f (or an Infra-Control 80f), the
maximum number of locomotives depends on the combination of
the units you are using:
from 1 to 99 Intellibox and C80f
from 1 to 80 Intellibox, C80f and Central Unit (Motorola
format: 6020, 6021, 6022, 6023)
from 1 to 99 Intellibox, C80f and Central Unit (DCC
format: 6027, 6029, 6030, 86028)

DCC Central Units 6027, 6029, 6030, Arnold 86028.
• To connect these Central Units you need a special adapter (art.
#692)
• These units must be powered on at the same time of the Intelli-
box. Their supply voltage must be feeded using a transformer
separate from the Intellibox transformer. Any electrical link be-
tween the Intellibox transformer and the Central Unit transformer
is not allowed! A Maerklin Central Unit connected using the spe-
cial adapter #692 must be connected immediately close to one
side of the Intellibox!
• The control panel of some units can be used to control locos
through the Intellibox internal Booster.
• The output section (red+brown) of the Central Units can be used
to power the turnout decoders of the layout on a separate elec-
trical circuit.
•It is not possible to control locos using the power ouput section
(red+brown) of these units.
• If you are using the Märklin Central unit 6027 you have to press
the reset button of this unit during a system power up!
• If you are using a Maerklin Central unit 6029 or 6030, it is only
possible to use the booster of this unit. The control panel does
not work, because it is not connected to the I
2
C bus.

backlight. The display is divided in three parts and is designed in
order to give the user a quick and clear view of the available com-
mands. At both sides the display shows the rel-
evant loco decoder format, the address,
the speed level and the driving direction.
In the middle part the display shows infor-
mation on the presently active mode. For
example: the current position of the sole-
noid devices in "keyboard mode" or the
text for the menu driven programming
mode.
4.2 Key functions
[go], [stop], [stop]+[go]
Switch the digital voltage on (go) and off (stop). A system reset is
performed when ([stop]+[go]) are pressed at the same time for
about 2.5 seconds.

The structure of the
menus of the Intellibox
During navigation in the menus the display shows the relevant
messages instead of the status of locomotives and turnouts. Don‘t
worry! All control functions for locomotives (not for turnouts, unfortu-
nately) are still active: knobs for speed and direction change, func-
tion keys [f1]-[f4], [function]-[off] keys. Therefore, during navigation
you are still able to control the last selected locomotives.
4.3.2 Special characters of the display
Should a menu level include further menu levels, then the first
character in the second row of the display will be a ">".
Should the menu entry be a parameter value, which could be acti-
vated or changed, then the first character in the display will be a "=".
All activated entries are marked by a "*" character at the end of the
display line.
All active entries are indicated with a character “*” at the end of the
line.

5.2.2 Speed knobs
Here you can choose the style of the speed knob. An AC style knob
or a DC style knob could be chosen.
The default factory setting is the "AC style knob".
The AC style knob
The AC style knob mode works like an old-fashioned three rail AC
controller.
Using the AC style, the speed will always be increased while turn-
ing the knob clockwise and will be decreased
while turning the knob counterclockwise. If the
max. speed or the speed zero is reached, a fur-
ther turn of the knob in the same direction has
no effect. The max. speed or the speed zero will
be maintained.
A slight push on to the speed knob will reverse the direction of the
loco.
Pushing the speed knob during driving will stop the loco first (emer-
gency stop). Then the direction will be changed. Depening on the
decoder format, some locos stop immediately (Märklin, DCC) while
other locos stop using their current deceleration rate (Selectrix).
DC style knob
The DC Style mode works like a DC speed control device for DC
two rail systems.
Using the DC style, turning clockwise the speed knob starting from
a zero speed level will increase the speed of the loco in forward
direction. Turning the speed knob counterclockwise
will decrease the speed until the zero speed level is
reached. A further turn of the knob will reverse the
direction of the loco and will increase the speed in
reverse direction. If the max. speed level is reached,
further turns of the knob in the same direction will not
cause any change. On the other hand, when speed zero is reached,
you will be allowed to change direction to the locomotive only after
about half a second. Only after this pause is a further knob rotation
accepted. This feature prevents unwanted direction changes.
A slight push on to the speed knob will stop the loco. Depending on
the decoder format some locos will stop immediately by a loco
dependent emergency stop (DCC) while other locos will stop us-
ing their current deceleration rate (Maerklin Motorola, Selectrix).

5.1.1 Some examples of navigation
Following these simple examples and using the Table of section
5.1 you will be able to navigate through all menus without any prob-
lem.
Let‘s first suppose to change the Intellibox language to Spanish.
• [menu] key
•
[mode] key
• With the
[$] key scroll until you read “Language“
• Enter the Language menu with the
["] key
• With the
[$] key scroll until you read “Espanol“
• Select this language by pressing the
[8] key
• With the
[menu] key you go back to the main display
Quite obviously, now you need to re-execute the same procedure in
order to tell the Intellibox to speak English. Try it!
And now we want to change the syntax of the serial interface to a
“6050 only“ syntax
• [menu] key
•
[mode] key
• With the
[$] key scroll until you read “Interface“
• Enter the Interface menu with the
["] key
• With the
[$] key scroll until you read “Syntax“
• Enter the Syntax menu with the
["] key
• With the
[$] key scroll until you read “6050 and Intellibox“
• Select this setting by pressing the
[8] key
• With the
[menu] key you go back to the main display
Re-execute the same procedure to set the Intellibox to “6050 only“
syntax.
5.2 Menu "user interface"
5.2.1 Loco speed display
The speed of the loco can be displayed in two different ways.
Absolute Speed (default factory setting)
The speed level will directly be displayed using the current operat-
ing level. According to the choosen data format the display will
show numbers in the range 0-14, 0-27, 0-28, 0-31 or 0-127.
Percentage of maximum speed
The speed level will be displayed in percentage of the maximum
speed independently of the current data format.

5.5 Menu "Accessory (decoder) setting"
Solenoid device decoders from Märklin, Viessmann and Modeltreno
are compatible with the Motorola format. Their addresses is de-
fined using suitable microswitches (DIP switches) that can be found
inside each unit. Each decoder is characterized by a unique ad-
dress. In the Appendix you can find a table showing the microswitch
position for each address.
On the contrary, DCC/NMRA-compliant solenoid device decoders
have no microswitches and can be programmed using the Pro-
gramming track - or directly on the “main track”.
5.5.1 General type
The general data format used for most of your accessory decod-
ers. After defining a general type you can define the type of each
solenoid device decoder following the instructions of section 5.5.2.
The default factory setting is the Motorola format.
Possible choices are:
Motorola
accessory decoders using the Motorola data format:
Märklin, Modeltreno, Viessmann, Uhlenbrock.
DCC
accessory decoders using the DCC data format:
Roco, Arnold, LGB, Lenz, Märklin=, Digitrax, etc.
5.5.2 Single type
Independently of the general data format for accessory decoders,
you can choose an individual data format for each accessory de-
coder address.
The address of a decoder which should get an individual data
format must be entered in the first input column after the word
"Addr".
The ["] key can be used to jump to the right input column.
Now the desired data format can be chosen by using the keys [$] or
[+] and entered by the [8] button.
5.3 Menu "Language"
Here you can choose the language of the displayed text.
Possible languages are: 1) German
2) English
3) French
4) Italian
5) Dutch
6) Swedish
7) Spanish
8) Portuguese
The default factory setting is English. It is also possible to change
thedefault language byswitching the Intellibox on while pressing
one key from 1 to 8 (see the previous table). For example, by
pressing the “4“ key you will set the default language to “Italian“.
5.4 Menu "Loco data format"
Here you can choose the default loco data format. This format will
automatically be used when new decoder addresses are intro-
duced, if no other format is explicitly defined.
This menu should be used to define the data format which will be
normally used.
The default factory setting is the new Motorola format.
Possible formats are:
Motorola - old
Old Motorola data format.
Loco decoder without additional functions.
Old-fashioned function decoders (e.g. Märklin coach with automatic
waiter or Digital crane) will be controlled by [f1] - [f4].
Motorola - new
Also called Gauge-I-Format, including the extended functions f1-f4.
DCC 14-27-28-128
DCC format using 14, 27, 28 or 128 operative levels.
DCC 28-128 DAC
DCC format with 28 and 128 operative levels with decoder as-
sisted consisting (DAC).
SELECTRIX
Trix selectrix with 31 operative levels.
The digital format of each locomotive can be modified independ-
ently of all other locomotives. Detailed instructions are given in
section 6.5.

H0 scale
The output voltage will not be controlled to a fixed maximum level. It
could reach a max. level of 21V peak voltage if the input AC voltage
is 16V.
N scale
The output voltage is clamped to a peak voltage of 18V.
5.8 Menu "Programming Track"
The Intellibox features an internal relais, connected in such a way
that an existing track of a layout (Programming Track) can be used
either as a “real” Programming Track or as a “normal” track.
Here you can choose whether the programming track connector
will output the programming voltage only, or if it will automatically
be switched between the normal track voltage and the programming
voltage.
Programming Track only
The programming track output is never connected to the normal
digital voltage. The connector outputs a voltage (the programming
voltage) only during read and write operations.
Automatic
The programming track connector will automatically be switched
from the normal track voltage to the programming voltage when
entering the programming mode.
The defauft factory setting is automatic.
Both rails of the programming track must be electrically isolated
from the normal track. It is not allowed to bridge the isolation points
with a bogie of a car or a loco.
An easy test of the Programming Track can be accomplished by
reading the configuration variables of a newly purchased decoder
(e.g. DCC/NMRA: reading CV1 in “bite mode” should give CV1=3).
If you have just installed a decoder, in order to check the electrical
connections it is advisable to test it first on the Programming track
(a low-current, low-energy track) instead of the normal track. Due to
this reason, we strongly suggest installers of decoders to choose
the option “Prg. Track only” in the configuration menu of the Intelli-
box.
HINT
CAUTION!
HINT
5.5.3 Switching time
The switching pulse triggered by the pressure on a keyboard button
usually lasts until the button is released.
Here the minimum and maximum switching times of the accessory
decoders can be changed. You can introduce values between 50
and 9999.
1st column: Minimum switching time.
The min. duration of the voltage pulse for switching an accessory
decoder, even in the case of either a very short manual actuation or
a computer command. The defauft factory setting is 100 ms (0.1
seconds). The input value will be rounded to the nearest 50 ms.
Should you input a “zero“ value, the switching pulse will be issued
only until the key is pressed.
2nd column: Maximum switching time.
Correspondingly, the max. switching time defines the max.
duration of the voltage pulse for switching an accessory decoder,
even when no command will reach the Intellibox to switch the
accessory decoder off. The default factory setting is 5000 ms (5
seconds). The input value will be rounded to the nearest 50 ms.
Should you input a “zero“ value, the switching pulse will always be
issued until the key is pressed.
These settings are common to all solenoid device decoders.
5.6 Menu "Display"
The Display menu could be used to adjust the brightness and the
contrast of the LCD.
The adjustment can be done using the [$] and the [+] keys.
The [8] key will store the desired settings.
If you leave the menu without using the [8] key, the old settings will
be restored.
If the display is unreadable because of a wrong setting of the
brightness and/or contrast, you could recall the default factory
settings by switching the main power on while pressing down the
[+] key at the same time.
5.7 Menu "Scale"
By setting the scale the output voltage of the built-in Booster will be
adjusted. The “H0“ setting is for both H0 and big gauges (0, 1, G,
etc.)

5.10 Menu “s88 configuration”
In other digital systems, s88 feedback modules are read only by
computer command. The Intellibox, instead, continuously reads
and memorizes the s88 modules, in order to maintain an updated
status of the layout’s sensors. The computer can also query the
Intellibox about the occurrence and type of changes in the feedback
bus signals. In order to optimize the feedback bus operation, the IB
must be aware of the number of s88 modules connected to it.
“s88” entry
In this entry you should input the number of s88 modules con-
nected to the feedback bus.
Modules s88
connectd: .8
The maximum is 31.
5.11 Menu “Lokmaus address”
You can connect up to 8 Lokmauses in the 5-pin DIN connector n.3,
by means of “Y” adapters.
The Lokmaus has an eight position slider for locomotive selection.
Each of the eight positions can be assigned to a specific loco
address. The assignments are common to all the Lokmaus: in this
manner, you can control “only” 8 locomotives, even if you have 8
Lokmaus.
Use the first column of the menu (after “Pos”) to input the desired
slider position or use the [$] and [+] keys to review the available
positions (1-8).
Change the input column with the ["] key and input the locomotive
address (1 to 9999) to be assigned to this slider position.
Lokmaus Selector
Pos 1 = Loco 1
Factory defaults assign positions 1-8 to loco addresses 1-8, re-
spectively.
If you try to assign a Lokmaus to a locomotive previouly assigned to
another Lokmaus, the “Loc” field will display “Pos xx”, where “xx”
will indicate the position already assigned to that locomotive.
5.9 Menu “Interface”
5.9.1 Speed
You can select the transmission rate of the serial computer inter-
face (dependent on the software in use).
Possible choices are:
2400, 4800, 9600, 19200 bit/s
Factory default is 2400 bit /s.
5.9.2 Syntax
You can change the serial interface protocol used by the Intellibox.
The Intellibox can be controlled with the serial protocol of the Märklin
6050/6051 Interface (see Appendix). The Intellibox will also recog-
nize an extended serial protocol (“P50X”) fully compatibile with the
6050/6051 syntax (updated documentation will be available, from
February 1999, in the Modeltreno and Uhlenbrock homepages).
Possible choices are:
6050 (syntax) only
Only the syntax of the 6050/6051interfaces is used.
Intellibox (syntax) only
Only the syntax of the Intellibox is used.
6050 and Intellibox
Both syntaxes (P50 and P50X), are used simultaneously. The IB
automatically recognizes the syntax of the commands it receives.
Factory default is “6050 and IB”.
5.9.3 Computer
This option lets you choose the type of computer interface.
Possible choices are:
PC
IBM-compatible Personal Computer.
For the technically minded: if the “CTS” (clear to send) line of the
RS232 interface is high, connector 8 CTS pin outputs +12V, allow-
ing the computer to transfer data to the Intellibox.
Mac
Apple Macintosh Computer.
For the technically minded: if the “CTS” (clear to send) line of the
RS232 interface is high, connector 8 CTS pin outputs -12V,
allowinging the computer to transfer data to the Intellibox.

6. The control panel
Locomotives can be addressed and controlled by means of the
control panel. The IB has two independent control panels,located
left and right of the numeric keypad.
You can assign a specific data format (protocol) to each locomotive
address controlled by the IB. The IB can control, simultaneously
and independently, locomotive decoders conforming to different
protocols.
Use of the control panels is possible even when the IB is in pro-
gramming mode or when configuring the unit.

Use the [go] key to switch the digital voltage on in the normal track.
Pressing this key will act on both control panels.
You can reset the Intellibox by pressing both the [go] and [stop] keys
for two and a half seconds.

6.2.1 Selecting a locomotive address
In order to control a locomotive with the IB you must select its ad-
dress.
To select a locomotive address, first press [lok#]. The display will
show a blinking cursor in one of the address fields, prompting you to
input a value.
There are two methods to do it:
Address selection using the numeric keypad
• You have just pressed [lok#] (right?)
• Input the digits that form the whole address with the numeric
keypad
• Terminate address input:
- pressing the [8] key,
- pressing any other key in the control panel: [function], [off], [f1],
[f2],[f3],[f4],[lok#],
- turning the knob (throttle),
- pressing the knob to induce a change of direction.
Use the [C] key to erase wrong entries, one digit at a time. If you
cancel the whole address, a further press of the [C] key will recall
the previous address.
Address selection using the throttle
• You have just pressed [lok#] (right?)
• Turn the knob to change the address, clockwise to increase the
value, counterclockwise to decrease it.
• Terminate adress input:
- pressing the [8] key,
- pressing any other key in the control panel: [function], [off], [f1],
[f2],[f3],[f4],[lok#],
- pressing the knob to induce a change of direction.
Shouldyoutry to takecontrolof a locomotivewhich isalreadysteered
by another knob, the Intellibox will show the message "Loco used
by another controller!" After this message you are allowed to control
the relevant locomotive using both manual controllers (the external
and the internal ones). The endless regulation of the speed knob
of the Intellibox is really helpful in this operation, while the display
will continuously show the present speed of the locomotive.
6.2.2 Recalling from memory a stored address
The Intellibox stores in its memory the address of the last locomo-
tive controlled by each of the control panels. It is possible to recall
this address:
• Press [lok#] and then
• Press [$]. The last valid address is displayed and is ready to be
used.
HINT
In each control panel you will find the following elements:
The [f1] [f2] [f3] [f4] keys
These keys control the locomotive’s extended functions, e.g., lights,
sounds, smoke generator.
If you press [lok#] followed by one of the [f1] - [f4] keys, you will be
able to switch the f5 - f8 extended functions of DCC decoders (see
section 6.4).
The [function] and [off] keys
These two keys switch the locomotive lights on/off.
The [lok#] key
Starts the input of a locomotive address.
After completing the locomotive address input, you can change the
decoder protocol. Press [menu] and select the appropriate data
format (protocol).
If you press [lok#] followed by one of the [f1] - [f4] keys, you will be
able to switch the f5 - f8 extended functions of DCC decoders (see
section 6.4).
The speed knob (throttle)
Use the knob to change a locomotive speed and direction of travel.
Suppose that you have chosen with the [lok#] key a previously con-
trolled locomotive. Given the fact that the knob can rotate freely, the
IB automatically reads from its memory the previous operating level
of the locomotive, and takes control from that level.
Even if you are in the process of changing an IB parameter (in
configuration mode), you can still control a locomotive with a speed
knob: the ongoing configuration can proceed without problems.
6.2 The locomotive addresses
Each locomotive in a digital system can be controlled by means of
an “address”, a combination of digits that uniquely identifies the
locomotive’s decoder.
Each decoder has its own address. An address should identify
