GAUGEMASTER DCC32 Manual

DCC32 DCC Point Decoder with CDU
Please read these instructions fully before connecting and powering up!!
Introduction
The DCC32 is a Point controller designed to control most standard Solenoid type point motors
and offers the following facilities:
• DCC Control of 4 point motors using DCC accessory commands
• A Route store to allow multiple points to be changed using a single command
! ! • Control of 4 point motors using conventional switches
! ! • Built in Capacitor Discharge unit (CDU) for enhanced power
Please note that the DCC32 is electrically similar to the Train-Tech PC200 on which it is based.

Making it easy....
DCC stands for Digital Command Control and is a system which transmits both power and
digital commands down 2 wires or rails to control and power locomotives and accessories.
We believe that DCC should make it easier to build, control and use model railways, so all of
our range of DCC Signals, Controllers and accessories connect using just 2 wires and are all
setup using just a single button press which we call 'One-Touch DCC'.
This may be the first accessory you have controlled by DCC and if so you need to be aware that
accessories are controlled by a slightly different command than the locomotives.
Accessory commands are completely different to Loco commands and most DCC hand and
computer linked controllers offer this facility, usually by pressing a specific button to enter into
accessory command mode (eg ACC) or by using a specified range of addresses for accessories
(eg on the Hornby Select addresses over 60 are for accessories only). There are only a few
controllers which do not offer control of DCC accessories including the basic Bachmann EZ
command (as supplied in sets) and Prodigy Express (not the Prodigy Advance which does).
The DCC32 can connect directly to the nearest DCC track to minimise wires - it takes both its
commands and power from the rails. As well as changing points, solenoid point motors can also
be used to actuate some semaphore signals & uncouplers (eg Hornby R8244 uncoupler).
The DCC32 incorporates a CDU (Capacitor Discharge Unit) which uses a capacitor to store
power from the DCC system for a few seconds and then release it quickly to activate a point
motor with more energy. This means it does not take the large amount of power needed for a
solenoid all at once which might overload your DCC system and just takes a few seconds to
recharge before you can operate a point again. If your route changes more than one Point there
will be a few seconds delay between each change to give the CDU time to fully recharge.
