When CV29’s bit 4 is set to “1” it will use the speed table formed by CV67-CV94
to control speed (motor voltage). It allows you to setup each speed for all 28
speed steps. First, program CV29 to 18 for short addresses (1-127) or program
CV29 to 50 for long addresses (128-9999) to enable speed table control. Then
select throttle to 28 speed steps and run your loco at speed step 1. Use program
CV on the main to change CV67’s value (1-255) to adjust step 1’s speed. The
kick voltage, CV65 is only applied when the speed step changes from 0 to 1. You
should switch between 0 to 1 many times to check step 1’s speed. When done
with CV67, select speed step 2 and program CV68. CV68’s value must be
greater then CV67’s. When done with CV67-CV94, use read back CV to make
sure their values are in increasing order.
Note: When using MRC Prodigy DCC to program addresses it will automatically
disable the speed table (set CV29’s bit 4 to “0”). Programming CV125 to 1 will
also disable the speed table and re-program CV67-CV94 to a default linear
speed setting.
TROUBLE SHOOTING
Loco running without chuff sound click F12. Whenever the decoder doesn’t
work please use the program track to program CV #125 with value 1 to restore
the decoder to factory settings. This should bring the decoder to life with
address #3. This decoder should perform well with all DCC systems. The maximum
DCC output should be less than 18 V. If the locomotive does not respond to
commands, it may have lost its address. Please re-program the address and
program CV19 to 0 (disable consist). If it responds slowly, you should clear its
momentum by reprogramming CV3 and CV4 to zero. If step 1’s speed is too high,
you should program start voltage, CV2 to zero. If its top speed is too slow, program
top voltage CV5 to 31. You should also clean the track to improve electrical pickup.
Read your DCC system manual to learn how to program and operate the decoder.
For more information about registers/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.

INSTALLATION
DCC base unit
It is quite a challenge to install the decoder in your loco. You should have some
basic electrical knowledge. If you do not have, please ask the dealer for help in the
installation.
Figure 1 shows the electrical circuit of most standard locos. The terminals of the
motor and lights are directly connected to the wheel pickup. Each type of loco
has its own method of electrical pickup and distribution. There is no standard
rule for installing decoders. It is always better to consult the loco manufacturer
on how to install a decoder in your particular loco. First, figure out your loco’s
electrical wiring and how to disconnect (isolate) the motor and light(s). Label all
wires before you disconnect them.

HOW TO WIRE THE DECODER
This decoder is equipped with a wire harness that has an N.M.R.A. 8 pin medium
plug on one end that simply plugs into a dcc ready locomotovive. If your
locomotive is not dcc ready and does not have a decoder plug, use the following
directions:
The decoder will be inserted between the wheel pickup and the motor. After
disconnecting the motor terminals from the pickup, connect the right side pickup
wires to the red decoder wire, and connect the left side pickup wires to the
black decoder wire. Connect the right motor terminal to the orange decoder wire,
then connect the left motor terminal to the grey decoder wire. Always use good
soldering techniques, and use shrink wrap to isolate the connections. The white
decoder wire is for the front headlight and the yellow decoder wire is for the
rear light. The blue decoder wire is the light common. Use double-sided sticky tape
to place the decoder in a safe place. The decoder can’t touch any metal part or bare
wires. The 17 mm speaker should have an enclosure made for a better sound
quality.
If you have a 1.5V bulb or LED, you should connect a 2k ohm resistor in series to
one of the leads to limit current.
MAKING A TEST TRACK
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 will
reduce the chance of damaging your decoder due to an incorrectly installed
decoder. Note- The test track is not your program track.
The decoder has been programmed to address #3, 28/128 speed steps. To test,
place the loco on the test track. Select address #3 and 28 speed step. Move up
the throttle and the loco should move. Push the light button [F0] and headlight
should come on. Change the direction of the loco and the loco should change
direction. The loco cannot reach full speed, due to the resistor. If all the 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.
As long as you test the decoder on the test track there is little chance of damaging
the decoder. This is why the test track is so important.
OPERATION
The decoder has 20 types of chuff sounds (10 single and 10 double). You can
use F24 to select them or F6 to turn the chuff off. With our unique double chuff
enable, (CV 122), you can also have 10 articulated chuff sounds. You can use
F19 to select 17 different whistles. You can also use F18 to select 7 different
bells. With MRC Prodigy Advance2 DCC which has 28 functions, you can easily
setup and access all the decoder’s functions. With all other DCC systems you
have to use CV programming to setup the decoder.

This decoder is equipped with adjustable back EMF load control feature. It is a
closed loop speed control. With back EMF load control the locomotive will maintain its
speed regardless of pulling up hill or driving down hill. You may program the back EMF
load control intensity, CV124, to a lower value to get less back EMF load control. This
will enable the locomotive to slow down during uphill travel like real locomotive.

The PID controller contains three components: proportional gain (CV113); the
integral gain (CV114); and derivative gain (fixed). Fine tuning a PID controller is
difficult and experimental on part of the end user, so we optimized these settings
at the factory, but still give the customer the ability to make final adjustments. We
recommend that you do not change these settings. Too much gain may cause
the motor to oscilate (become unstable). Too little gain may cause slow
response. Additional knowledge of PID feedback control is required before
attempting to adjust CV113 and CV114. If CV113 and CV114 are programmed
incorrectly, the locomotive will not run smothly. Program CV125 to “1” will automatically restore the default PID controller settings.
