TROUBLESHOOTING
This sound decoder should perform well with all DCC systems. Whenever you find
the decoder doesn’t work properly please clean your track and the loco’s wheels.
And reprogram loco address or program CV125 with a value of 1 to restore
factory defualt setting. Your decoder may simply lose its memory. All you may
need to do is to reprogram its address. See your DCC system manual to
learn how to program and operate the decoder. For more information about
register/CVs and their functions, please refer to the NMRA DCC Standard &
Recommended practices, RP-9.2.2 this is available directly from the NMRA or their
website at www.nmra.org.
Due to the nature of all sound decoders, the CV read back feature is not support in
the dwecoder. This is not a defect of the decoder or your DCC
Whenever the decoder doesn’t work please use program track to re-program the
loco address or program CV# 125 with value 1 to restore the decoder to factory
setting. This should bring the decoder to life.
FCC COMPLIANCE
This device complies with the part 15 of FCC rule. Operation is subject to the
following two conditions. (1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that
cause undesired operation.
RETURNPROCEDURE
If it should become necessary to return your decoder, unplug the decoder and
return the decoder only. Please include a letter (printed clearly) with your name,
address, a daytime telephone number, and a detailed description of the problem
you are experiencing. Please also include a $15.00 check for shipping and
handling. Be certain to return only the decoder.

INSTALLATION
If your loco has a NMRA 8 pin receptacle, simply remove the dummy plug and
match first pin and plug in the decoder. Otherwise it is quite a challenge to install a
decoder into a loco. You should have some basic electrical knowledge and
soldering skills. If you do not have the above requirements, please ask the dealer
for help in installation.
Figure 1 shows the electrical circuit of most standard locos. The terminals of the
motor and light(s) are directly connected to the wheel pickup. Each type of loco
has its own method of electrical pickup and distribution. The connection between
the wheels, motor and light(s) could be wires, clips, the body or chassis, PC
board or any other type of conductor. First, figure out your loco’s electrical wiring
and how to disconnect (isolate) the motor and light(s).
Note: The ‘X’ marks indicate
where to disconnect (isolate).
Figure 2 shows how to wire the decoder. After disconnecting the motor terminals
from the pickup, connect the red wire to the right side pickup and the black wire to
the left side pickup. Connect the orange wire to the motor terminal that was
originally connected to the right pickup. Connect the gray wire to the motor’s other
terminal. Connect the front light to the blue wire and the white wire. Connect the
rear light to the blue wire and the yellow wire.
The blue wire is the common terminal for lights and accessory functions. You may
use the black wire or the red wire to replace the blue wire. This is useful when
isolating one of the light terminals from the pickup is difficult. Wiring the bulb this
way will make the light dimmer. If your loco has only a front light, you should
connect the white and the yellow wires together.
Use the green and brown wires coming from the decoder for the firebox flicker.
OPERATION
There are eleven whistle sounds, four bell sounds, and three air pump
sounds for you to choose. The choice of air pump sound is for randomly
played sounds when the loco is at idle. If using the MRC Prodigy Advance
DCC System, you can use F19 to scroll through eleven different horns.
Synchronizing Steam Chuff needs a series CV programming. First program
CV #123 to select back emf on (CV #123=1) or off (CV #123=0). When emf is
on, you must connect the motor to get chuff sound. Program CV #121 with a
right value to make chuff sound start when loco start to move. Program CV
#120 to change chuff rate to make four chuffs for per revolution. It may take
many times to try to get a perfect synchronization.
Double clicking your headlight button (F0) will turn the steam sounds on or
off. When the steam sounds are turned off, all accessory function sounds
will also be turned off.
You can use F12 to turn the steam chuff sounds on or off. When the loco is
drifting the chuff should be off. On real steam loco, once they are up to
speed the engineer will shut off power to conserve steam and fuel. When
loco is moving you can use F6 to switch between chuff sound and railroad
click sound.
There are many more program features available with this decoder. Please
refer to the CV Chart to explore other features of the decoder.
STEAM SOUNDS / ACCESSORY FUNCTION CHART
Each manufacturer and loco may have different ways of decoder
installation. There is no standard rule for installing decoders. It is always
better to consult the loco manufacturer on how to install a decoder in that
particular loco.
All the decoder’s light outputs are track output voltage (around 14V)
supplied by your DCC system. They are designed for 12V light bulbs.
Please contact your loco manufacturer for lights’ operation voltage. If
you have a 1.5V bulb or LED, you should connect a 1k ohm resistor in
series to one of the leads to limit current.
SPEAKERSELECTION
The decoders come with a 28mm 8 ohm speaker. A 20mm or 16x35mm rectangular
speaker can be purchased from MRC. However, reducing speaker size will affect
the overall sound quality. Use hot glue or double-sided sticky tape to affix the
speaker inside the loco shell.
MAKING A TEST TRACK
Before you begin decoder installation, we strongly recommend building a test track
with a 27 ohm resistor to limit current. Only test your installed decoder on the test
track. The test track may prevent damage from an incorrectly installed decoder.
Note: The program track is NOT a test track. The program track does not use a current
limiting resistor. So it will not protect an incorrectly installed decoder.
TEST
The decoders has been factory programmed with address #3, 28/128 speed
steps and maximum top voltage. Never run the installed decoder on your
layout without first successfully running on test track. Otherwise, you
may damage the decoder if it is not wired correctly or if you have not properly
isolated the motor and lights.
To test, place the loco on the test track. Select the “Run” mode of your DCC
system and select or acquire address #3. Move up the throttle and the loco should
move forward. Push the light button [F0] and the front headlight should come on.
Change the direction of the loco and the loco should change direction and the rear
headlight (if equipped) should come on. The loco cannot reach full speed, due to
the resistor. If all above occurs, you passed the test. Congratulations!
Do not run the loco for an extended period of time on the test track or
the resistor will overheat.
If your installed decoder does not pass the test, find the problem, correct it and
test it again.
