Making Points ‘Live’
Please Note:
Always use Hornby Point Motors with Hornby Points.
When wiring a Hornby Point Motor to a Hornby Digital Point/Accessory Decoder, the connections are:
+ Red wire
c Black wire
- Green wire
For your layout to operate efficiently it is essential that all the track is "live."
Hornby points are self isolating therefore it is necessary to fit each point with 2 x R8232
Hornby DCC
Electric Point Clips
in order that power will be fed to all track connections from the point.
Please note that these clips are adequate for situations where you wish to make a siding live. However, if your
point configuration allows locomotive to move from one track loop to another it is recommended that power
is supplied via "link wires" to the other track section.
Some of these clips are included in the Hornby DCC sets, further clips and wire links are available from
Hornby stockists.

Glossary
Acceleration
It is possible to change the rate at which a locomotive accelerates via programming functions of the controller.
See page 10.
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
See “Power Bus”.
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
D
igital
C
ommand
C
ontrol.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.
