Welcome to the digital Hornby World of model railways.You are about to enjoy a new and exciting experience
when it comes to controlling and operating a model railway.
Using the keypad that is on the Select unit locomotives can be “called up” individually and operated just like the
real thing. Imagine a busy marshalling yard where the locomotives are positioned close together and where by
using the Hornby Select Digital Controller, Hornby digital locomotives can be manoeuvred from one place
to another without having to worry about the complexities of having to connect metres of wiring to a bank of
switches and isolating sections and hoping the whole thing will work!
The Hornby Select Digital Control has the ability to address 59 DCC locomotives and 40 points or accessories.
The following instructions are a guide on how to get the best from your Hornby Select Digital Control.
Please take a little time to read carefully through the instructions before you start to assemble the track. Should
you have any questions then you can either contact Hornby via the Hornby DCC website (www. hornby.com),
or write to Hornby using the email address: [e-mail]

Keyboard
The keyboard has 16 keys used to register and programme
locomotives or accessories, set inertia or acceleration levels,
direction settings, and for emergency stopping! The Select
allows for 59 locomotives to be registered to the unit and
40 accessories. Each locomotive can be coded with up to
99 levels of acceleration or deceleration speeds.
Locomotives have an ID number allocated to them from
1 - 59 and similarly accessories are given numbers of 60 - 99.
Rotary Control
Once the locomotive required to run has been “called up”
and the direction of travel has been decided the model is
ready to go. By turning the rotary control clockwise the
locomotive will move off with the speed being proportional
to the amount the control knob has been rotated.
If an acceleration level has been chosen then a more gradual
acceleration can be expected depending on the setting.To
slow the locomotive down, the knob is turned anti-clockwise
and similar to the acceleration programming, if a
deceleration setting has been coded into the loco the model
will gradually slow.
LCD Display
The LCD Display screen of the Select shows the number
of the locomotive or accessory which is in the process of
being selected.This number will flash until the function
button is pressed.
The number will remain on the screen until another
locomotive or accessory is chosen.The screen also displays
various other functions and operating instructions that the
Select features.
Power
The Select is powered by a 220-240V AC wall-mounted
Switch Mode transformer which supplies 1amp 15V AC
power to the track as well as power to an uncontrolled
outlet which can be used as an alternative electrical source
to provide power for point motors and accessories in the
traditional analogue manner.
A larger 4 amp transformer is available for use with the
Select unit which will provide additional power to the
tracks allowing for more locomotives to be run
simultaneously.
Assemble the track as per the instructions included with the set.
For DCC to operate at its full potential, it is important that the locomotives receive a strong and consistent
signal from the Select. Ensure the track and connecting fishplates are clean. It is also advisable to secure the
track using R207 Hornby Track Pins to prevent movement and loose connections. For advice about cleaning the
track and locomotive wheels, see the Troubleshooting section.
1. Locate the terminals at the rear of the Select unit labelled ‘Track’.
2. Locate the Track to the Controller Link Wire, and insert the black lead into Socket Aand the black and
white lead into Socket B. (These wires must not be inserted into mains socket outlets).
3. Locate the Power Input Track section on the track circuit.
4. Press down on the left hand button on the Power Input Track section and insert the black and white lead of
the Link Wire into the socket and release the button.
5. Repeat the process, inserting the black lead into the right socket of the Power Input Track.
Connecting the Digital Control Unit
1. Locate the Power Transformer with integral cable.
2. Locate the Power Input socket on the rear of the unit.
3.Take the Power Supply cable and insert the plug into the Power Input socket situated at the rear of the
Select unit.
4. Plug the Power Transformer into the mains socket and switch on the power.
Please Note: There is no On/Off switch on the Select unit. Always ensure that the power supply is
disconnected from the Select when not in use.

Should you wish your locomotives to have varying levels of acceleration/deceleration then you must
programme them all individually.
However if you require all your locomotives to have the same level of acceleration/deceleration you
need not remove them from the track. In this instance programming one locomotive with accelera-
tion/deceleration will programme them all.
Please Note:
If locomotives 1, 2 and 3 are already programmed into the controller by repeatedly pressing the “SELECT”
button, it is possible to scroll through the locomotives. For example by scrolling through and stopping at No. 2,
No. 2 locomotive will respond to the controller. The speed of the locomotives will not change in relation to
the position of the control knob while scrolling through addresses.When the Control Knob is turned again
the speed will be adjusted on the currently selected locomotive.
All locomotives included in the Hornby Digital Train Set range are
factory fitted with Decoders. To achieve the maximum benefit of
operating a Digital layout,ALL locomotives should be fitted with a
Decoder.
1. Place one locomotive on the track, and select its address using
the keypad.
2.To operate the locomotive, turn the Control Knob on the Control
Unit clockwise until the locomotive has reached the desired speed.
3.To slow down and stop the locomotive, turn the knob anti-clockwise.
4. Direction of travel is controlled using the direction arrows on the unit keypad. Generally the currently selected
direction is indicated by a green LED below the button.To change the direction of the locomotive, press the
opposite Direction button to the one currently selected.

The Select control units feature two methods of “calling up” locomotives that are stored in the units memory.
The keypad can be used to enter locomotive addresses directly, or the Select button can be pressed to cycle
through the list of stored addresses.
Method 1: To select a locomotive address directly using the keypad.
1. Enter the locomotive address on the keypad.
2. Press “SELECT“ to confirm.
The LCD Display will show the new locomotive address.
Method 2: To cycle through the locomotive address stored in the control unit’s memory...
1. Press “SELECT“ repeatedly until the locomotive required shows on the LCD display.
2.The locomotive displayed can then be directly controlled.
Selecting Locomotives
It is a commonly accepted practice in the United Kingdom that when a locomotive is in operation, other than when
shunting, the front of the locomotive normally faces to the left.
This is easy to determine when operating steam locomotives but not quite so obvious where a diesel or electric
locomotive have double cabs.As a rough guide the front of a diesel has the roof fan closest to the front, while
an electric locomotive’s front is determined by having the pantograph furthest away. These are general guides
but are not necessarily absolute.
After assigning an address to a Locomotive, it may not move in the direction indicated by the green LED on the
control unit.This can be corrected by the following procedure.
Correcting Locomotive Direction:
1. Ensure the locomotive is stationary.
2. Press and hold the unlit direction key (or ).
The LCD will display either “Fd” or “rd” for one second.
The red LED will flash twice.
3. Press the unlit direction key.
The green LED will illuminate below the button.
4.Turn the Control Knob clockwise to move the locomotive.
5.The locomotive will now move off in the corresponding direction.
Running multiple locomotives on one layout has the potential for accidents and collisions to take place, if not
properly managed.To help avoid such incidents, the Hornby Select Digital Control unit features an Emergency
Stop button. Pressing this button causes all activity on the layout to cease.
Emergency Stop Procedure:
1. Press the “STOP” button located on the Select unit.
The LCD display will flash “E5” (Emergency Stop).
All activity on the layout will cease.
2.Turn the Control Knob fully anti-clockwise.
3. Press STOP to restore power to the layout. It will be noticed that all locomotives will remain stationary.To
commence movement each locomotive will need to be reselected to the control individually.This will give the
operator time to reorganise each locomotive’s movements.

Double/Triple Heading (Basic Consisting)
For more information visit: www.hornby.com
Please Note:
When locomotives are placed in a Consist the levels of acceleration and deceleration will automatically
default on the Consist locomotives to “0”. If acceleration and deceleration levels are required follow
instructions as per page 8. Note:When the Consist is dissolved the levels of acceleration and deceleration
will remain at the levels set during Consist.
Please Note:
The Select can Consist a maximum of 3 locomotives.
14 15
Double Heading

6. Using the keypad, enter the address of the second locomotive you wish to add to the Consist (No. 3).
Press “SELECT” and the LCD will display the Consist address.
7.The three locomotives will now be Consisted, and can be controlled in unison.
Please Note:
As the Select is equipped for basic consisting some speed disparity between locomotives may occur.
When the Consist is dissolved the levels of acceleration and deceleration will remain at the levels set
during the Consist.
Dissolving a Double Triple Group:
1. Ensure all locomotives in the Consist are on the track.
2. Enter the address of the Consist you wish to delete and press “SELECT“.The LCD displays the chosen address.
3. Press and hold “CANCEL“ for 1 second.The LCD display will flash “CA”.
4.The LCD will flash each locomotive address in the Consist for 2 seconds each.
5.The Consist has now been dissolved.
6.These actions refer to dissolving both double headed and triple headed groups.

It is possible but not recommended that a locomotive that is not fitted with a decoder (analogue) can be operated
on a digital layout.This locomotive is given the address “0”.
Running an Analogue Locomotive:
1. Press on the keypad. Press “SELECT” to confirm. The LCD will display 00.
2.Turn the Control Knob clockwise to move the locomotive.
Pressing the or buttons on the keypad controls the direction of the locomotive.
The acceleration and deceleration of the locomotive is controlled via the Control Knob only.

Please Note:
If a digital locomotive is called up for operation the analogue locomotive will continue to run at the speed
set prior to the digital locomotive being operated.
It is not possible to program into the analogue locomotive acceleration or deceleration levels.
When an analogue locomotive is placed on the track it will emit a high pitched noise when stationary,
which will become louder when running, this is normal.
Only one analogue locomotive (No. 0) can be run on a digital layout at anyone time.

The Hornby Select Digital Control unit can have stored in its memory 59 digitally controlled locomotives.
At any one time the Select can have running (providing the power is available) or on standby 10 locomotives.
This is more than sufficient for an above average layout, however should an eleventh loco be “called up”, one of
the previous 10 locomotives will be returned to the memory.The locomotive that is returned, will be the
locomotive that has the lowest current Speed address compared to the other 9.
Alternatively, if all 10 locomotives are stationary, the locomotive with the lowest address number will be returned
to the memory.
Control Up to 10 Locomotives
The transformer included with the Select unit will probably provide enough power to allow for three locomotives
to be running at any one time, providing the models used are fitted with power efficient motors. Should more
power be needed the Select unit is capable of being connected to a R 8113 Hornby 4 amp Power Unit which
should provide enough power for an average layout.
If under special circumstances even more power is needed it may become necessary for a “Booster” unit to be
fitted.This will entail the track circuit to be broken up into large isolating sections to which the Booster is connected.
The Booster will in turn be connected to the XpressNet port at the back of the Select unit.
There are several “Boosters” on the market, with each one supplied complete with the relevant fitting
instructions.
Consult your Hornby DCC dealer for further details and advice.
15V DC Analogue Accessory Power Supply
The Hornby Select Digital Control unit incorporates a separate 15V DC outlet which can be used to power
non-digital controlled accessories (analogue) such as point motors or similar devices as well as lighting.

This denotes that the Select unit now has control.
4. Next turn the Walkabout control knob so that the locomotive starts to move.The Select LCD display will
not flash, indicating that the Select’s control knob is fully in the “Stop” position.
Operation 2 - Controlling two or more different locomotives using the
Select and Walkabout.
Example 1: For this example locomotive Nos. 1 and 2 are assigned to the Select and
Walkabout.
1. Assign locomotive No. 1 to the Select.
The LCD will display “01”
2. Using the Walkabout key pad assign locomotive No. 2 to the Walkabout.
The LCD will display “02”
3. Both units will now operate independently from each other.
4. Both units can be used to “call up” and address other locomotives as per the Operating Instructions.
(See page 10).
It is possible for locomotives to be interchanged between the Select and the Walkabout while they are in
motion. During this operation the locomotive concerned will remain at the set speed before being transferred.
Once the control knob is moved full control is obtained.
Either the Select or the Walkabout can be used to programme locomotives.To program a locomotive, ensure
all locomotives are removed from the track, other than the one to be programmed, and disconnect all point
decoders. it is recommended that a Programming Track is used. See page 22.
There may be occasions when locomotives fitted with older generation decoders may make a ‘guest appearance’
on a Select controlled layout.
Some of these locomotives may require to have their Speed Step changed.To do this follow this simple procedure.
1. Press and hold “FUNCTION“ + “CANCEL” for 1 second.
2.The Speed Step will increase with each press of “FUNCTION“ + “CANCEL”, 14, 28, and H5 (128).
3. Press “SELECT” to confirm the required Speed Step setting.

Programming Track
When addressing locomotives and Hornby Point/Accessory Decoders it is important that all other locomotives
are removed from the track. It is also important that all point decoders are disconnected from the layout.
This can become rather difficult at times, therefore it is suggested that a Programming Track is used for the
allocation of addresses.A Programming Track is a length of track electrically isolated from the main circuit but
includes one Hornby R8206 Power Track and an R046 lever switch.To initiate the Programming Track, (see
diagram below) use the Lever switch to connect or disconnect from the track layout.
To programme a locomotive follow the instructions on Page 7.
In respect of R8216 Point/Accessory Decoders it is not necessary for them to be in position and connected to
their respective point motors for them to be programmed. It is much easier if they are programmed on the
Programming Track.This is simply done by connecting the R8216 Point/Accessory Decoder to the track, (using
the R602 Power Clip) supplied with the unit this will allow for the programming to be carried out as described
on Page 25.
23
The four function R8215 Hornby Digital Decoder features:
Load compensation (Back EMF): Locomotive will run at a consistent speed either on the “flat” or on
gradients.
Selectable for operation with 14, 28 or 128 speed steps: The greater the number of speed steps the
smoother the acceleration. All Hornby decoders are factory set at 128 steps.
Four On/Off function outputs: Two of the function outputs are dedicated for the direction of lights-front
and rear.
Analogue operation: Locomotives fitted with a Hornby Digital Decoder can be operated on an analogue
system but without the benefits of digital control.
Overload cut-out: The Hornby Digital Decoder is rated at a 500mA continuous current and 1Amp for a
short period. Should this be exceeded then the decoder will overload and cut out.This action protects not only
damage to the decoder but also the locomotive.
Dimensions: 17mm x 10mm x 3.5mm
Hornby Digital Decoder

Hornby Digital Points Decoder
The Hornby Select Digital Control is capable of operating up to 40 points or solenoid operated accessories when
used in conjunction with the Hornby R8216 Points Decoder Module.
The Point Decoder Module can operate up to 4 points or solenoid operated accessories.
Fitting the Hornby Point/Accessory Decoder:
1. Connect the wires from the point accessory motor to the first available input terminals on the decoder.Then
connect the wires from the point decoder to the track or Programming Track (see page 22). Full wiring
instructions are supplied with each Module.
Addressing Points/Accessories:
Addressing a point motor or accessory that uses a solenoid motor is very similar to addressing a locomotive.
For consistency it is advisable that the first point motor/accessory is addressed No. 60. Once addressed the
other three outlets will be automatically programmed to 61, 62, 63.There after, the Accessory Decoder should
be programmed in consecutive blocks of 4 (i.e 64, 67, 72, 75 etc).When programming subsequent Point Decoders
ensure that other Point Decoders are disconnected from the track.
Programming:
1. Press and hold “SELECT”.The LCD display will flash “LA”.

The Hornby Select unit operates most efficiently when the whole of the layout is “live”. Hornby points are self
isolating therefore it is necessary to fit each point with 2 x R8232 Hornby DCC Electric Point Clips.
Some of these clips are included in the Hornby DCC sets, further clips are available from Hornby stockists.

Glossary
26 27
Acceleration Delay
The delay between the locomotive being stationary and reaching the desired speed.
Accessory Decoder
An electronic decoder designed for use in track side accessories such as points or signals.An accessory decoder
is not for use in a locomotive.
Address
A number used to identify a locomotive or accessory that is either equipped or linked to a Decoder.
Bus
Technical term for wires that carry electrical signals around a model layout.
Command Station
The Command Station is the ‘brains’ of a DCC system. A Command Station is in essence a micro-computer/
controller that communicates with the decoders that are located either in a locomotive or connected to
accessories.The computer transmits signals to the decoders instructing them what to do, such as accelerate,
decelerate, brake or switch lights on or off.
Configuration Variable (CV)
A technical term referring to the operating information of the particular locomotive or accessory that is stored
on the specific decoder.This information will remain “set” until changed using the Command Station.
Consist/Consisting
Consist is an American term, but in the UK it is known by Double or Triple Heading.This is where two or more
locomotives are brought together and function as one.
There are three types of Consisting (1) Basic consisting where the locomotive decoders in the Consist have the
same address. (2) Universal Consisting where the Consist information is stored in the Command Station.
(3) Advanced Consisting is where the Consist information is stored inside the decoder.
DCC
Digital Command Control.The application of computer technology to control the movements of locomotives.
Each locomotive is fitted with a decoder (or ‘chip’) which is uniquely programmed and recognises its own
identity and responds only to those control signals which are addressed to it.
DCC also allows a wide range of extras including controllable lighting and on-board sound.The accepted
standards have been laid down by the NMRA (National Model Railroad Association) an American Association.
Deceleration Delay
The delay of a locomotive slowing down to a standstill.
Feedback (Load Compensating)
This allows a locomotive to remain at a constant speed regardless of loads being pulled or incline being
negotiated.
Locomotive Decoder
A small PC board which contains a ‘chip’ that stores control information; normally fitted in locomotives.The
Command Station sends coded information to the decoder which can then control the locomotives speed,
direction and any operating functions that the locomotive may have eg lights.
Locomotive Decoders can be fitted to accessories that have a motor as a drive for example the R8131 Hornby
Operating Conveyor or the R8132 Hornby Tipper set.
Occupancy Decoder
A unit that can detect the presence of a locomotive on a specific section of track and can provide the appropriate
information as ‘return’ data.
Power Bus
Copper strip or wires that can relay power from a Power Booster to the track.
Power Booster/Power Station
A Power Booster or Power Station is as the name implies there to provide a boost of power to the track.This
can occur if a larger than normal quantity of locomotives are required to be running on the track at the same
time. If the transformer already fitted cannot handle this number then it will be necessary to section the layout
and fit a Power Booster.
This Booster will not only provide more ampage to the drive locomotives but also boost the signals to the
Decoders. All Boosters fitted must still be connected to the Power Station.
Programming
The process of assigning an Address to a locomotive or accessory (points or signals).The process of programming
sends a signal containing a numerical identifier to the locomotive being programmed.
Programming Track
A section of track isolated from the main layout purposely for programming locomotives. Programming on a
Programming Track negates the requirement of removing other locomotives from the main layout.

Speed Steps
A variable voltage increase used to control motor speeds. Decoders can set the output power for each
speed step.
Stall Current
Stall Current is the maximum current draw in amperes that a locomotive is capable of when stalled. If the
armature of a motor is prevented from turning and the maximum voltage is applied the current draw of the
motor is known as the ‘Stall Current’.
Throttle Notches
Determines whether a locomotive is controlled with 14, 27, 28 or 128 speed steps.
XpressNet
A high-speed communication protocol used for connecting Digital input devices together.
XpressNet (XBUS) Input Devices
Devices using the XpressNet protocol to control a digital layout.
Locomotive will not run
Check that all the wiring is correctly connected to the track and Controller and that the transformer is plugged
into the wall and is switched on.
Ensure that the correct loco address is displayed on the LCD.
Check that the “STOP” button has not been pressed accidentally.
The trains do not run smoothly
The locomotives require a clean track so that they can receive their information from the Select, therefore
ensure that the track is clean. Use an R8087 Track Rubber to remove dirt from the track and wheels of the
locomotive. Do not use any other abrasive material as this will permanently damage the track and/or wheels.
All locomotives move off together
Make sure that a locomotive has not been given a new address while other locomotives have been on the same
track.To avoid this it is advisable to use a Programming Track to add new addresses to locomotives and Hornby
Point/Accessory Decoders. See page 22
All locomotives appear to have the same Acceleration/Deceleration levels.
All locomotives appear to have the same Acceleration/Deceleration levels
Make sure that a locomotive has not been programmed with acceleration and deceleration levels while other
locomotives have been on the same track.To avoid this happening it is advisable to use a Programming Track to
add new addresses to locomotives and Hornby Point / Accessory Decoders. See page 22
System keeps cutting out
Check that there is no metal across the track that may be causing a short circuit.Also check that the system is
not being overloaded by too many locomotives trying to run at the same time.
The 1amp transformer included with the Select should within reason be capable of providing enough power to
run three locomotives. If in doubt consult your local dealer or the Hornby DCC Helpline.
Trouble Shooting
Do not connect any other controller to the Hornby Select other than a Hornby Elite or another Hornby
Select Unit.When using a Select with the Hornby Elite ensure that the Select is not connected directly to
a mains transformer. Similarly, when using two Selects which are connected together only one of them must
be connected to a mains transformer.
Do not run coreless motored locomotives on a DCC layout without them having a decoder fitted.
If in doubt please contact Hornby or your local dealer for advice.
