DCC Programming Quick Reference & Tips..................... 18
Throughout the manual we will use “DC” to refer to
operation using a traditional DC power supply and “DCC”
to refer to operation with a NMRA compliant Digital
Command Control system. Almost every operational
feature of this locomotive can be congured to suit your
personal taste by setting conguration variables (CV’s).
Many of these apply to DC and to DCC operation. See
the list of conguration variables in this manual and the
Paragon 4 Technical Reference Manual available at www.
broadway-limited.com for more information.
Rolling Thunder
Your Paragon 4 locomotive is equipped with Broadway
Limited’s new Rolling Thunder transmitter. This system
sends the low frequency sounds to a reciever and sub
woofer that greatly enhance the locomotive’s built in
sound system. The reciever and subwoofer are part
#1595. To use, install the receiver and subwoofer beneath
your layout as described in the receiver manual, then
operate the locomotive as you normally would in DC or
DCC. The model can be operated without the subwoofer
or receiver. The volume of low frequency sound played by
the subwoofer can be adjusted using CV 214. The default
is 128. O is off, 255 is the loudest. See the manual that
came with your Rolling Thunder receiver for more details.
Go Pack
The Paragon 4 sound decoder includes a built-in Go Pack
capacitor to power the locomotive through momentary
track power glitches. The loco will operate for several
seconds after power is interrupted. This feature is
automatically disconnected on the programming track to
facilitate CV reading. The duration of capacitor run time
can be reduced by setting CV12 to the number of seconds
desired, from 0 - 10. The default is 5 seconds. Set CV12=0
to disable this feature for block control operation.

Operation with a DC Power Pack
HO Scale Paragon 4 diesel locomotives are ready-to-run.
Simply place the locomotive on a track powered by any
DC power pack with a variable output up to 16 volts DC.
As you increase the track voltage, the sound system will
begin functioning at around 9 volts DC. If you increase
track power slowly, you will hear the sound of a diesel
locomotive starting, then idling. As you slowly increase
track voltage, you will hear the sound of a diesel engine
increasing in speed as the locomotive prepares to move.
Once under way, you will hear the engine increasing its
RPM. There are a number of sounds the locomotive will
produce automatically to simulate the sound of a full-size
diesel locomotive.
If you do not use DCC, the DC Master Analog Control
Module (BLI stk# 1011), is required for activation of the
whistle, bell and some other sounds, and to control the
volume. It can also program CV’s without a DCC system.
The DC Master is shown in gure 1, connected between
the power pack and the track.

Bell The bell turns on when the “bell”
button on the DC Master is pressed.
It turns off when the “bell” button on
the DC Master is pressed a second
time. The interval between bell rings
can be adjusted by setting CV180. A
Lower number is faster. Set CV 223
to 1 to select an alternate bell. 0 is
default.
Air Compressor Press the “AUX” button on the
DCMaster while the locomotive is
stopped.
Dynamic Brakes Press the “AUX” button on the
DCMaster while the locomotive is
moving.
Automatically Activated Sounds
Startup The sound of a diesel locomotive
starting is heard when the track
power is turned on.
Shutdown The sound of a diesel locomotive
being turned off is heard when track
power is lowered to about 7 volts.
Brake Set Plays automatically when the
locomotive shuts down.
Brake Squeal Plays automatically when the
locomotive is slowed quickly.
Diesel Rev Levels The sound of a diesel locomotive
speeding up and slowing down is
heard when the model changes
speed or load.
Randomly Activated Sounds
The following sounds will be heard when the locomotive

is running or sitting at idle. Various other random sounds
may play if appropriate for each locomotive.
Spit Valve Compressor
Air release Air lling
Fuel Fill Wheel Flange
Radiator Cooling Fan
Volume/Mute
To mute the sounds, press the “Vol” button once. To turn
the sounds back on, press the “Vol” button once. Horn
and bell still work when the other sounds are muted.
Your Paragon 4 locomotive’s sound system has 8 volume
levels that can be set from the DCMaster. At startup, it
is at the loudest setting. To lower the volume, press the
“Vol” button on the DCMaster two times quickly (like
double-clicking a mouse button on a PC). The volume will
decrease 1 level each time you do this. When the lowest
level is reached the volume will start to increase with
subsequent double-clicks of the button until the highest
volume level is reached, at which point the coupler sound
will play to signal maximum volume.
Tip: To make the locomotive always start at a lower
volume, set CV 133 to some number lower than 128. 0 is
off, 255 is max.
Tip: The volume of many sound features can be set
independent of the overall volume by setting CV’s 135
through 156 with the DC Master. See the next section.
Setting Conguration Variables (CV’s)
without DCC
Your Paragon 4 locomotive’s sound system is highly
congurable even without DCC by using the DCMaster.
Most of the locomotive’s functions are controlled by
setting Conguration Variables (CV’s). To change a CV:
1. Place the locomotive on the track with track
power off. Hold down both the “Aux” and Vol”
buttons on the DCMaster while turning track
power on to maximum voltage. The locomotive
will not move. The display on the DCMaster will

7
Paragon 4 With Rolling Thunder
read “E01.”
2. Press the bell(-) button or horn(+) button to scroll
past E15, then to the CV numbers which range
from 1-255 (There is no ‘E’ in front of the CV
numbers.) Stop at the one you want to change
and press the “Vol” button.
3. Use the bell(-) button or horn(+) button to scroll to
the new value, then press “Vol” to accept.
4. Turn off track power to nish programming.
Tip: The locomotive you are setting should be the only DC
Master compatible locomotive on the track. Otherwise all
locomotives on the track will have their CV’s reset.
Changing the function of the AUX button.
The AUX button can be made to do other functions by
changing CV222 with the DC Master. Select the desired
function from the table on page 15 and enter it into
CV222. See page 9 for a listing of the functions and their
descriptions.

Consists
Paragon 4 locomotives can be set to run in a DC consist with
each other by setting CV 230 to 1,2, or 3, which designates
the locomotive as front, middle or rear facing rear
locomotive, respectively. The rear loco facing backwards
since railroads commonly run the rear loco in reverse. This
automatically sets the lights, bell and horn to respond
appropriately. To break the consist, simply program zero
into CV230. (To make the rear facing loco forward facing,
Set CV230 to 3, then change CV229 to 1 to enable the
rear light.)
Paragon 4 locomotives start moving at a higher track
voltage than non-sound locomotives. This is done to allow
the sound system to start working before the locomotives
moves. As a result, it is difcult to consist a sound
locomotive with a non sound locomotive in DC operation.

DCC Operation
Paragon 4 Locomotives come equipped with an integral
DCC decoder. Is automatically detects if you are using a
DCC system and responds appropriately.
FACTORY DEFAULT ADDRESS = 3.
To Reset, set CV8 = 8.
When programming on the main line in Operations Mode,
the locomotive will make a coupler sound to indicate when
a CV is changed. It will not make the coupler sound if the
same number is programmed into a CV. It will not make
the coupler sound on the program track. CV’s associated
with the address cannot be changed while the locomotive
is moving. This includes CV’s 1, 8, 17, 18, 19, 29, and
230.
DCC Programming
To change the engine ID, rst, make sure you can run
the locomotive as engine #3 and blow the horn. Then,
reprogram the engine ID on the main track or the program
track following the procedure for your DCC system. (Note:
Lenz systems do not allow changing address on the main
line. Use the program track. See page 24.)
Diesel Function Key Denition
Paragon 4 locomotives have the ability to use dozens of
functions. If your DCC system does not support this many
functions, the function you want to use can be assigned
to the function keys available on your DCC system. The
default function keys are listed below. To change the
assignments, see page 15.

Pressing F0 turns the front and rear light on and off. The
light intensity can be adjusted with CV 231.

Pressing F1 turns on the bell. Most controllers allow
the bell to stay on until the F1 is pressed a second time.
Lower CV 180 to speed up the bell.
Diesel Horn (F2)
Pressing F2 activates the horn. The Paragon 4 horn is
highly playable. If you use the horn button instead of F2,
a quick press and release plays a short horn blast while
