1. Description
Besides being a smart add-on throttle for digital Command Stations, the
DAISY can also be connected to a Power2, thus yielding a complete
digital (as well as analog train control) system – and is referred to as
the “DAISY-System”. The DAISY software can be updated anytime.
1.1 Operation modes
DAISY-throttle
The DAISY can be connected to digital Command Stations featuring
LocoNet (e.g., the Intellibox, the Twin-Center, the DAISY-System, etc.).
The DAISY can be used to control all locomotives supported by the
Command Station it is connected to. It can also be used to control up to
256 turnouts or signals.
DAISY-System (digital mode)
Used as a digital control system, the combination of DAISY-throttle plus
Power-2 constitutes a multi-protocol digital Command Station for the
Motorola old and new format (locomotive addresses 1 through 255) and
for the DCC format (14, 28 and 128 speed steps; locomotive addresses
1 through 9999). Locomotives of all these protocols can be freely
“intermixed” at the same time on the same layout. Furthermore, if all
locomotives are of the DCC format, it can also be used to control,
through locomotive address zero, an analog locomotive (a locomotive
not equipped with a digital decoder). Turnouts and signals decoders
can be either of the Motorola or of the DCC format. DCC decoders can
be programmed using either CV or Register mode.
Important! Important! Important! Important! Important!
Analog locomotives used with the DAISY-System in digital mode emit a
low level whistle because a high frequency current always flows
through their motors.
This current damages some type of motors, for example coreless
motors (e.g., Faulhaber, Escap, etc.) and some types of small N-scale
motors. These motors must be used with a digital decoder if they are to
be run on digital layouts.
If in doubt, please ask the locomotive manufacturer in order to find out
whether the locomotive (motor) is compatible with this kind of operation
on a digital layout.
DAISY-System (analog mode)
This is a new feature previously not available with any other product.
The DAISY-throttle, used with one or more Power2’s, provides a
comfortable and expandable system for controlling analog layouts
(locomotives and trains not equipped with digital decoders).

DAISY
5
Locomotives driven by the power output of each Power2 are controlled
by a pulsed high voltage current (PWM – Pulse Width Modulation). This
allows for smoother operation at low speeds.
The function keys available on the throttles – keys which would
normally only be used in a digital environment – can now be used to:
select among several acceleration and deceleration factors, activate a
“switching speed” (half of normal speed), choose motor type (PWM
frequency: low for normal motors, high for coreless motors), etc.
The DAISY-System in analog mode can be expanded to up to 63
independent electric circuits, each connected to and powered by its
own Power2. Each current circuit can be controlled by one or more
throttles (e.g., DAISY, FRED, IB-Control, etc.).
Furthermore it is also possible to configure one Power2 so as to
interpret the turnout/signal commands issued by throttles or other
devices (e.g., IB-Switch, Switch-Control, etc.) and convert them to
digital commands for DCC accessory decoders. This allows for analog
train operation and digital turnout/signal control.
1.2 Memory function
As the power to the layout is turned off, DAISY memorizes
In digital mode:
•the last selected mode (drive or turnout)
•the last selected locomotive
•the last selected turnout address range assigned to the function
keys
In analog mode:
•the last selected electric circuit (Power2)
1.3 How to connect it
Analog mode - driving a ‘conventional’ layout, i.e., an analog (non
digital) layout
If a DAISY throttle is to be used for controlling a conventional layout,
then it should be connected to the “LocoNet” connector of the last
Power2 (also check the Power2 manual), using the provided spiral
cable.
Digital mode (DAISY-System)
If a DAISY throttle is to be used as a digital Command Station for
driving a digital layout, then it should connected to the “DAISY” con-
nector of the first Power2 (also check the Power2 manual), using the
provided spiral cable.
Important During use as a digital Command Station, the DAISY must not be remo-
ved from the “DAISY” connector of the Power2.

DAISY
6
Throttle mode
If the DAISY is to be used as an add-on throttle, then it must be
connected to the Command Station using a suitable LocoNet
connection. In case the Command Station is a DAISY-System, any
additional DAISY throttle should be connected to the “LocoNet” con-
nector of a Power2 (or to a cable extension/connector coming from
there).
If necessary, one can “branch” LocoNet as required (so as to allow for
connection of more devices or throttles). This can be done, e.g., using
our “LocoNet multiple outlet box” (art. Num. 62 250).
TIP While used as an add-on throttle, the DAISY can of course be unplug-
ged (disconnected) and re-plugged (re-connected) to LocoNet as
required.
Important Please use only Uhlenbrock or so called “standard” cables for con-
necting the DAISY. Using the incorrect type of cable, or a cable
improperly configured may cause damage to the DAISY

2. Digital mode (DAISY-System and DAISY throttle)
Used as a digital control system, the combination of DAISY-throttle plus
Power-2 (which we call “DAISY-System”) constitutes a multi-protocol
digital Command Station for the Motorola old and new format
(locomotive addresses 1 through 255) and for the DCC format (14, 28
and 128 speed steps; locomotive addresses 1 through 9999).
Furthermore, if all locomotives are of the DCC format, it can also be
used to control, through locomotive address zero, an analog locomotive
(a locomotive not equipped with a digital decoder). Turnout decoders
can be either of the Motorola or of the DCC format. DCC decoders can
be programmed using either the CV or the Register mode.
2.1 Operation
(1) Large 4-digit display for showing all system
information
(2) Rotary encoder used as a speed knob for
controlling the loco speed and also for loco
selection, turnout address selection and for
value/parameter input during programming
(3) Driving direction indicators (triangular LEDs)
(4) [Stop]: layout Power Off/On toggle
(5) Turnout key for activating turnout
mode and for turnout/signal ad-
dress selection
(6) Programming key for per-
forming DCC programming
procedures and for the setup
of DAISY operational para-
meters (Special Options)
(7) Locomotive key for drive
mode selection and for loco-
motive (address) selection
(8) Function keys [f1] through [f4]. These keys control locomotive
functions in drive mode, while they control turnouts in turnout
mode
(9) [Off] key for turning the locomotive lights off
(10) [function] key for turning the locomotive lights on
Speed knob
The speed knob is used for controlling the locomotive speed. Turning
the speed knob clockwise increases locomotive speed, while turning
the speed dial counterclockwise decreases locomotive speed. If the
locomotive is stopped or if it has already reached its maximum speed,
further rotations in the corresponding direction are ignored.
If you select a locomotive which is moving, the throttle automatically
displays the locomotive speed and let’s you control the locomotive

DAISY
8
starting from that speed – the same applies, of course, for all
locomotive functions (e.g., the locomotive lights, functions, etc.).
Driving direction
The locomotive driving direction can be changed by pressing the speed
dial. The current driving direction is shown by the two triangular LEDs
next to the [Stop] key. The LED pointing to the right lights up if the loco
driving direction is “forward”. No LED will appear lit if the selected
locomotive has the “Motorola old” format.
If the loco direction is changed by pressing the speed dial, the
locomotive first stops, then changes its driving direction.
[Stop] key
The [Stop] key can be used for turning off/on power to the layout. If the
layout power is off, the display shows 4 blinking decimal points. If the
layout power is off due to a short, then the display shows the outer and
the middle decimal points blinking in an alternating pattern.
[function] and [off] keys
The [function] key turns on the lights of the currently controlled
locomotive, while the [off] key turns them off. If the locomotive lights are
off, pressing the [off] key turns them on only as long as the [off] key
remains pressed.
[f1] through [f4]
In drive mode, these keys allow controlling special functions F1 through
F4 of the currently selected locomotive. Pressing one of these keys
toggles the status of the corresponding function. The four LEDs above
those keys show the current status of the corresponding function.
After pressing the [Locomotive] key, these four LEDs show the status of
functions F5 through F8 (and, keys [f1] through [f4] can be used to
control those – as long as the [Locomotive] key remains pressed).
However, if the DAISY is either part of the DAISY-System (i.e., it is
connected to a Power2 through its “DAISY” connector) or is connected
as add-on throttle to a DAISY-System, then functions F5 through F8 are
not supported — and, therefore, cannot be controlled.
In turnout mode, these keys allow controlling four turnouts at a time.
The four LEDs show the status of the corresponding turnout, indicating
either ‘green’ or ‘red’.
2.2 Drive mode
The drive mode of the DAISY is activated by pressing the [Locomotive]
key. In drive mode one can drive locomotives, change their speed
and/or driving direction and control their lights and additional functions.
One can also select a different locomotive for control through the
DAISY.

DAISY
9
If the DAISY is connected to a Power2 through its “DAISY” connector
(and, therefore, is part of the DAISY-System), then it is also possible to
setup the loco type and address.
In drive mode, the display shows the loco type and speed, for example:
M 7 Motorola format locomotive driving at speed 7
D112 DCC format locomotive driving at speed 112
2.2.1 Locomotive Selection
The DAISY has 16 memory locations for storing locomotive addresses.
The default configuration is such that these contain addresses 1
through 16 in Motorola new (“Mot2”) format. By pressing the
[Locomotive] key (while in drive mode), one can select among the 16
memory positions (i.e., the 16 locomotive addresses).
Any one of the 16 memory locations which has been deleted (i.e.,
which does not hold any locomotive address) will not be shown during
this locomotive selection process.
This is how to proceed:
•Press the [Locomotive] key. The display indicates:
Loco
•Release the [Locomotive] key. The display indicates the currently
selected locomotive address, e.g.:
7
•Rotate the encoder in order to view the other 15 memory locations
(excluding those which may have been erased, of course).
•Select the desired loco by pressing the [Locomotive] key – or abort
locomotive selection (regaining control of the previously selected
locomotive), by pressing either the [Turnout] or [Prog] keys.
2.2.2 How to edit or erase a locomotive address
The locomotive addresses can be edited or erased. In order to do this,
the DAISY has to be connected to a LocoNet Command Station (e.g.,
an Intellibox, a Twin-Center, etc.) or to the “DAISY” connector of a
Power2.
Attention It is not possible to edit or erase the locomotive addresses on a DAISY
throttle connected as an add-on throttle to a DAISY-System.
How to edit only non-erased memories
•Press the [Locomotive] key. The display indicates:
Loco

DAISY
10
•Release the [Locomotive] key. The display indicates the currently
selected locomotive address, e.g.:
7
•rotate the encoder in order to select the memory position you wish to
either edit or erase.
•press the [Locomotive] key and keep it pressed. The display shows:
Edit
•After about 2 seconds the locomotive address starts blinking.
•Release the [Locomotive] key: both direction LEDs will be lit.
•Rotate the encoder in order to edit the locomotive address. A faster
rotation results in a bigger address change. You can use the [Off] key
in order to erase the address. The display would then indicate:
----
TIP It is not possible to store the same locomotive address twice (that is: the
same locomotive address in two different memory locations). In fact,
each locomotive address which is already stored in an other memory
will be shown with all decimal points turned on and the DAISY will not
accept any command to memorize that address (again).
TIP DAISY-System (digital mode): if all digital locomotives have been set to
the DCC format, then it is possible to drive an analog locomotive (i.e., a
locomotive not equipped with a digital decoder) through the address 0.
That address will automatically be set to the type “DC”. If such a
locomotive address is defined, then the DAISY does not generate any
Motorola locomotive digital signal anymore.
•Confirm address editing or deletion by pressing the [Locomotive] key
– or abort locomotive address editing by pressing either the [Turnout]
or [Prog] keys.
How to edit all memory locations (including the eventually erased
ones)
•Press the [Locomotive] key and keep it pressed. The display shows:
Loco
•After about 2 seconds the locomotive address will be displayed.

DAISY
11
•At this point, if the rotary encoder is not operated, the display alter-
nately shows the locomotive address and the memory position, e.g.:
7and -01-
any memory position which has been erased will display as having
the “address”:
----
•Press the [Locomotive] key and keep it pressed. The display shows:
Edit
•After about 2 seconds the locomotive address will begin to blink.
•Release the [Locomotive] key: both direction LEDs will be lit.
•Rotate the encoder in order to edit the locomotive address. A faster
rotation results in a bigger address change. You can use the [Off] key
in order to erase the address. The display will then indicate:
----
•Confirm address editing or deletion by pressing the [Locomotive] key
– or abort locomotive address editing by pressing either the [Turnout]
or [Prog] keys.
TIP The 1st memory position can be edited; however, it cannot be erased.
2.2.3 How to edit the locomotive format (type)
It is possible to edit the locomotive type associated with any of the 16
memory positions. In order to do that, the DAISY throttle must be
connected to the “DAISY” connector of a Power2.
Attention It is not possible to edit a locomotive type if the DAISY throttle is
connected as an add-on throttle to a LocoNet Command Station (e.g.,
to an Intellibox).
How to show the current format (type) of a locomotive
•Press the [Locomotive] key. The display indicates:
Loco
•Release the [Locomotive] key. The display will show the currently
selected locomotive address, e.g.:
7
•Press the [function] key. The display shows the type of the currently
selected locomotive, e.g.:
Mot1

DAISY
12
•Press the [function] key again. The display shows the address of the
currently selected locomotive, e.g.:
7
•Press the [Locomotive] key to go back to drive mode.
The possible locomotive types are shown as:
Mot1 Motorola old
Mot2 Motorola new
d 14 DCC 14 speed steps
d 28 DCC 28 speed steps
d128 DCC 128 speed steps
-dc- analog locomotive
(can only be selected through address 0)
How to edit the current format (type) of a locomotive
•Press the [Locomotive] key. The display indicates:
Loco
•Release the [Locomotive] key. The display will show the currently
selected locomotive address, e.g.:
7
•Rotate the encoder in order to select the memory position you wish to
either edit or erase.
•Press the [Locomotive] key and keep it pressed. The display shows:
Edit
•After about 2 seconds the locomotive address will begin to blink.
•Release the [Locomotive] key: both direction LEDs will be lit.
•Press the [function] key. The display shows the type of the currently
selected locomotive, e.g.:
Mot1

DAISY
13
•Rotate the encoder in order to select a different locomotive type, e.g.:
Mot2
•Confirm type editing by pressing the [Locomotive] key – or abort type
editing by pressing either the [Turnout] or [Prog] keys.
2.2.4 How to dispatch a locomotive address
It is possible to use a DAISY throttle in order to “pre-select” (dispatch) a
locomotive address for later control by a throttle which does not feature
any locomotive (address) selection capability (e.g., a FRED in dispatch
mode or a Profi-Control). Through this procedure, the desired
locomotive address can be saved in a so-called “dispatch memory”,
from which a device can read it later.
This is how to proceed:
•Press and release the [Locomotive] key. The display will show the
currently selected locomotive address.
•Press the [Off] key and keep it pressed. The display indicates:
Disp
•Release the [Off] key. The locomotive address has been dispatched.
2.2.5 Connecting additional throttles to a DAISY-System (digital)
If FRED’s or Profi-Control’s are connected to a DAISY-System (in
digital mode), then one can use the function keys f1 through f4 (FRED)
or f1 through f8 (Profi-Control) in order to select a locomotive. The
locomotives which can be selected are those which have been
memorized in the first four memory positions of the DAISY-System.
That is:
Memory position 1 2 3 4
FRED f1 f2 f3 f4
Profi-Control f1 or f5 f2 or f6 f3 or f7 f4 or f8

DAISY
14
2.3 Turnout mode
A DAISY throttle can control up to 256 accessories – turnouts, signals,
etc.
2.3.1 How to control a turnout or a signal
Press the [Turnout] key to switch from drive to turnout mode.
While in turnout mode, you can use the f1 through f4 keys to toggle the
status of a turnout or signal. The four LEDs above the f1 through f4
keys show the current turnout or signal status: red (thrown) or green
(closed).
The fact that the 4 LEDs indicate a ‘red’ or ‘green’ status – as opposed
to ‘yellow’ or off – can be used to tell the mode (turnout or drive) in
which the DAISY throttle is currently operating.
Each closure of the [f1] through [f4] keys will be shown on the DAISY
display: the accessory address which has been toggled will be shown
as long as the key remains pressed. For example, the display will show:
W 2
(the first symbol represents the letter “W”, to indicate “Weiche” the
German word for turnout).
While in turnout mode, the currently selected locomotive can still be
controlled through the rotary encoder and by pressing the [function] or
[Off] keys.
2.3.2 How to change the controlled turnout address range
The DAISY default is to have the keys [f1] through [f4] control turnout
addresses 1 through 4. However, this can be changed.
This is how to proceed:
•While in turnout mode, press the [Turnout] key. The display indicates
the turnout address controlled by the [f1] key (i.e., the “base
address”), e.g.:
W 1
•Rotate the encoder in order to select the desired new “base address”.
The base address can be edited in steps of 4 units. For example, a
single step (rotation) in the clockwise direction will indicate:
W 5
the highest possible value is 253.

DAISY
15
•Press the [Turnout] key in order to confirm selection of the new “base
address”. The display will now revert to indicate the speed of the
currently selected locomotive.
2.3.3 How to change the turnout format (type)
A DAISY-System can control Motorola (default) or DCC accessory
decoders. All controlled accessories (turnouts, signals, etc.) must be of
the same type: either all Motorola or all DCC. A mixed type operation of
accessory decoders is not possible.
The format of the accessory decoders can be changed only while the
DAISY throttle is connected to the “DAISY” connector of a Power2.
Attention It is not possible to edit the turnout format (type) if the DAISY throttle is
connected as an add-on throttle to a LocoNet Command Station (e.g.,
an Intellibox).
This is how to proceed:
•While in turnout mode, press the [Turnout] key. The display will
display the turnout address controlled by the [f1] key (i.e., the “base
address”), e.g.:
W 1
•Press the [function] key. The currently selected turnout format (type)
is displayed, e.g.:
Mot
•Rotate the encoder to select a different turnout format, e.g.:
dcc
•Press the [Turnout] key to confirm turnout type selection, or press the
[function] key to go back to turnout base address selection without
changing the turnout type.
Attention If an analog locomotive is being controlled through address 0, then
operating Motorola turnouts or signals will result in the analog
locomotive performing a short “jump”, possibly in the opposite driving
direction. This can be avoided by using DCC accessory decoders.

DAISY
16
2.4 Programming mode
The programming mode can be used to program (configure) locomotive
or turnout decoders and for changing configuration parameters of the
DAISY throttle. Decoder programming is only supported if the DAISY
throttle is connected to the “DAISY” connector of a Power2.
Important Decoder programming commands will be repeated by all boosters con-
nected to the DAISY-System. Therefore, it is important that only the
locomotive(s) which you wish to program/configure should be sitting on
the rails. Other locomotives must be temporarily removed from the
layout.
This is how to proceed:
•Press the [Prog] key. The display indicates:
ProG
•Release the [Prog] key. The display indicates the programming/confi-
guration option used last:
CCV (direct) programming
rRegister programming
SSpecial Options edit
The remaining 3 digits show the number of the CV, Register or
Special Option which has been selected last.
•Press the [function] key as required for the desired programming/con-
figuration option to be shown
•Rotate the encoder to select the desired CV, Register or Special
Option number
•Press the [Prog] key to select that particular CV, Register or Special
Option
•In case of a CV or Register, the display will indicate either 0 (zero) or
the value which has been written to a CV or Register last. Please note
that this is not necessarily the current value of the selected CV or
Register. In case of a Special Option, the display will indicate the
current value of the selected Special Option.
•Rotate the encoder to select the desired CV, Register or Special
Option value
TIP The value can be displayed in hexadecimal format by pressing the
[function] key. It will revert to decimal format as soon as that key is
released.
•Start CV, Register or SO programming by pressing the [Prog] key.
•The ongoing of CV and Register programming is indicated by “walking
dashes” on the display
•You can leave programming mode at any time by pressing either the
[Locomotive] or the [Turnout] key

DAISY
17
3 Analog mode
If the DAISY throttle is connected to the LocoNet connector of a
Power2 and if the “DAISY” connector of the Power2 is left unconnected,
then the DAISY-System (DAISY throttle plus Power2) is in analog
mode: it can be used for controlling an analog layout.
If the analog layout features more than one “electric circuit” (or section),
then it is possible to link (“daisy-chain”) several Power2 Boosters - up to
a maximum of 63 Power2’s. This is done by connecting the LocoNet
connector of the “previous” Power2 to the “DAISY” connector of the
”next” Power2. Implicitly, this defines an order among the Power2’s: the
first Power2 (the Power2 with number “1”) is the one which does not
have anything connected to its “DAISY” connector. The next Power2
(the one which is connected, through its “DAISY” connector, to the
“LocoNet” connector of Power2 #1) is Power2 #2, etc.
All LocoNet devices must be connected to the “LocoNet” connector of
the last Power2.
Each Power2 drives its own section of the analog layout (“electric
circuit”). Each throttle connected to the LocoNet connector of the last
Power2 can control any Power2.
Additionally, it is possible to configure the last Power2 so that is will
interpret turnout commands being issued on LocoNet (e.g., by an IB-
Switch, a DAISY throttle or an IB-Control) and generate the corres-
ponding digital commands which can be used to drive digital turnout
decoders. This allows for digital control of the turnouts of an analog
layout.
Obviously, if this option is used then that last Power2 cannot be used
for driving a section of the analog layout – since, indeed, its power
output is being used for driving the digital turnout decoders.
Important Digital locomotives (i.e., locomotives equipped with a digital decoder)
should not be used on an analog layout powered by a PWM power
supply (such as a Power2 in analog mode). Any digital locomotive used
in this manner will not function and even risks being damaged if the
PWM votlage is too high (which is not the case with a Power2).

DAISY
18
3.1 Operation
(1) Large 4-digit display for showing all system
information
(2) Rotary encoder used as a speed knob for
controlling the loco speed and also for loco
(electric circuit) selection, turnout address
selection and for value/parameter input
during throttle configuration
(3) Driving direction indicators (triangular LEDs)
(4) [Stop]: layout Power Off/On toggle
(5) Turnout key for activating turnout
mode and for turnout/signal ad-
dress selection
(6) Programming key for per-
forming DCC programming
procedures and for the setup
of DAISY operational para-
meters (Special Options)
(7) Locomotive key for drive
mode selection and for loco-
motive (address) selection
(8) Function keys [f1] through [f4]. These keys control locomotive
features in drive mode, while they control turnouts in turnout mode
(9) [Off] key: ends circuit-coupling
(10) [function] key: starts circuit-coupling
Speed knob
The speed knob can be used for controlling the locomotive speed.
Turning the speed knob clockwise increases locomotive speed, while
turning the speed dial counterclockwise decreases locomotive speed. If
the locomotive is stopped or if it has already reached its maximum
speed, further rotations in the corresponding direction are ignored.
If you select a locomotive which is moving, the throttle automatically
displays the locomotive speed and let’s you control the locomotive
starting from that speed – the same applies, of course, for all
locomotive functions (e.g., the locomotive lights, functions, etc.).
Driving direction
The locomotive driving direction can be changed by pressing the speed
dial. The current driving direction (that is: the track polarity) is shown by
the two triangular LEDs next to the [Stop] key. The LED pointing to the
right lights up if the loco driving direction is “forward”.
If the loco direction is changed by pressing the speed dial, the
locomotive first stops, then changes its driving direction.

DAISY
19
[Stop] key
The [Stop] key can be used for turning off/on power to the layout. If the
layout power is off, the display shows 4 blinking decimal points.
[function] and [off] keys
The [function] key starts the coupling of two electric circuits. This allows
a locomotive to smoothly pass from one electric circuit (supplied by a
specific Power2) to a different electric circuit (driven by a different
Power2). The coupling also transfers all locomotive features (e.g.,
acceleration and deceleration factors) from the first to the second
Power2. The [off] key is used to terminate the coupling, effectively de-
coupling the two Power2’s.
Functions in analog mode
In drive mode, the function keys (f1 through f4) can be used to control
features pertaining to the driving characteristics of analog locomotives.
Each Power2 (each electric circuit) has its own setting, which is
independent of the setting applied to other Power2’s.
[f1], [f2] acceleration/deceleration delay
[f1] off, [f2] off = minimum acceleration/deceleration delay
[f1] on, [f2] off = low acceleration/deceleration delay
[f1] off, [f2] on = medium acceleration/deceleration delay
[f1] on, [f2] on = maximum acceleration/deceleration delay
(Note: minimum delay means that a locomotive will react very quickly to
speed changes).
[f3] switching speed (i.e., half speed)
[f3] off = normal speed
[f3] on = switching speed (half of normal speed)
[f4] enable/disable acceleration/deceleration delay
[f4] off = acceleration/deceleration delay is enabled
[f4] on = acceleration/deceleration delay is disabled
[f5] motor control (low or high frequency)
[f5] off = low frequency (104 Hz) PWM (Pulse Width Modulation)
(e.g., for normal motors)
[f5] on = high frequency (16.7 KHz) PWM (Pulse Width Modulation)
(e.g., for coreless or Faulhaber motors)
[f7] loopback control (check Power2 manual)
[f7] off = closing the contact changes driving direction
opening the contact changes driving direction
[f7] on = closing the contact changes driving direction
opening the contact does not change driving direction
In turnout mode, these keys allow controlling four turnouts at a time.
The four LEDs show the status of the corresponding turnout, indicating
either ‘green’ or ‘red’.

3.2 Drive mode
The drive mode of the DAISY is activated by pressing the [Locomotive]
key. In drive mode one can drive locomotives and modify operating
parameters of the selected locomotive (electric circuit).
In drive mode, the display shows an “A” for “analog mode” plus the
current loco speed (0=stopped through 126=maximum speed). For
example:
A 98
In the following paragraphs the term “locomotive” will sometimes be
used instead of “electric circuit”.
3.2.1 Electric circuit Selection
In analog mode, the DAISY System can be used to control up to 63
different electric circuits (through an equal number of Power2’s).
The DAISY throttle default is to control the first electric circuit: #1.
The [Locomotive] key can be used to either activate drive mode (e.g.,
from turnout mode) or, if already in drive mode, to select a different
locomotive.
This is how to proceed:
•Press the [Locomotive] key. The display indicates:
Loco
•Release the [Locomotive] key. The display indicates the currently
selected electric circuit, e.g.:
1
•Rotate the encoder to select a different electric circuit.
•Confirm the selection by pressing the [Locomotive] key – or abort
selection (regaining control of the previously selected electric circuit),
by pressing either the [Turnout] or [Prog] keys.
3.2.2 Coupling electric circuits
The DAISY System allows one to couple the electric circuit in which a
locomotive is currently driving with the next electric circuit: the electric
circuit in which the locomotive is going to operate, after leaving the
current electric circuit. This allows a locomotive to move from one
electric circuit (layout section) to a different one.
This is how to proceed:
•While controlling the first electric circuit, press the [function] key
•Press the [Locomotive] key in order to start the locomotive selection
process
