SPEED TABLE CV67-CV94 FOR 28 SPEED STEPS
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
This decoder should perform well with all DCC systems. The maximum DCC
output should be less than 15 V. If the locomotive does not respond to com-
mands, 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. 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.

INSTALLATION
If your loco has an NMRA DCC 8 pin socket all you need to do is remove
the dummy plug and plug in the decoder. If the loco travels in wrong
direction you should change the decoder’s orientation. If you can not
change the decoder’s orientation due to the space limitation, you have to
program CV29’s bit 0 to value of 1. This will reverse the loco’s direction. If
you don’t know how to program CV29’s bit 0, you can simply read back
the value of CV29 (an even number) and add 1 to the value. And then
program the odd number back to CV29. For example, if the orignal value
of CV29 is 6, program 7 to CV29. If your locomotive does not have a NMRA
8 pin receptacle, you need order a NMRA 8 pin receptacle/harness from
your local hobby dealer and hard wire this into the loco.
We do not reccomend soldering wires to the pins themselves.
SPEAKER
The decoder comes with 20mm speaker. You may use 28mm round
speaker (0001511) for a wide body loco or use a 16x35mm speaker
(0001513) for a narrow body loco. The bigger 28mm speaker will improve
the overall sound.
DCC OPERATION
The decoders have been factory programmed with address #3, 28/128
speed steps and maximum top voltage. Select the “Run” mode of your
DCC system and select or acquire address #3. Move up the throttle and
the loco should move.
The decoder has 6 types of diesel prime mover sounds. You can use F12
to change the prime mover sounds. You can also program CV123 to
value of 0 to 5 to select the prime mover for your type of diesel engine.
The CV123 table shows the 6 prime mover sounds and their associated
locomotive types.
The decoder has a start up and shut down feature. If the loco has been
previously shut down, you have to start up the engine by simply pressing
any numbered function button. To shut down the engine you must bring
the loco to idle and then press F8 three times.
This decoder has 22 different horns. You can use F19 or program CV50
to select these 22 horns. You can also use F18 or program CV52 to
select different 8 bell sounds.
Most of the sounds have their own volume control CV. There is also a
master sound volume control CV49. Also F13 will reduce the master
volume by 1 (you will hear an air release when you reach CV49=1).
Pressing F14 will increase volume by 1 (you will hear an air release
when you reach CV49=16). Programming CV49 to 0 will shut the sound
off.
The decoder is default to automatic notching. You can program CV122
to 3 to set manual notching for realistic operation. Then use F9 to notch
up and use F8 to notch down. This simulates the way a real locomotive
operates.
This decoder is equipped with adjustable back EMF closed loop speed
control. Its proportional gain (CV113), integral gain (CV114) and deriva-
tive gain (fixed) are pre-tuned for most locomotives. 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.
Please get some basic knowledge of PID feedback control before trying to
adjust CV113/114.
There are many more program features available with this decoder.
Please refer to the CV Chart to explore other features of the decoder.
Note: Bell, Dynamic Brake and Rail Wheel Clack cannot play at the same
time. If you activate the Bell sound [F1], while either the Dynamic Brake or
Rail Wheel Clack sounds are activated, the Bell sound will override the
other 2 sounds. Rail Wheel Clack cannot play while the loco is in idle.
When you turn off Dynamic Brake and Rail Wheel Clack sound there will
be one second delay.
LIGHT EFFECT PROGRAMMING CHART FOR CV#118/119
You would program CV #118/119 to choose the desired light effect.
CV118 for ACC1 and CV119 for ACC2. For ditch light both CV118 and
CV119 must to 0. F3 control both ACC1 and ACC2. When you solder
wires to ACC1 and ACC2 solder pads please use thin wires and small
solder iron. Please make sure not cause any short circuit.
DC OPERATION
The decoder can also be operated by a regular DC power pack. This
will give you engine sounds only. If you wish to enjoy the full array of
sound functions using your DC power pack, the unique MRC Tech 6 2A,
(#0001200), will allow you to control all of the sounds in your sound
equipped locomotives.
