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
Your new Sound Decoder will virtually “drop-in” to a your Kato N scale PA1
series diesel locomotive. It may fit in many other N scale locomotives with slight
modification. Refer to the instructions that came with your Kato PA1
locomotive for removal of the body shell. Remove the original circuit board
by very carefully removing the plastic clip and sliding the PCB out. Don’t
lose the clip. There are two wheel pickup contact strips. These strips
must be wrapped with tape approx. 1/4 wide (as shown in the image
below) to prevent them from touching the motor leads. Trim off some
material from the plastic cradle under the motor brush tab area to
compensate for the tape thickness. After applying the tape and trimming
the plastic, reinstall the strips. before installing the new decoder, bend the
spring contacts under the rear of the decoder approx 45 degrees to
provide correct contact. Now, install the decoder in place of the original
PCB and reinstall the plastic clip you removed earlier. Apply a strip of tape
over the clip & down the chassis sides to help hold the decoder in place.
Re-install the body shell. Now your loco is ready to go to work on your
railroad.
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 following primer mover for matching your
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 press-
ing 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 defualt to automatic notching. You can program CV122
to 3 to set manual notching for realistic operation. And 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 derivative
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.
DC OPERATION
With DC operation only the last programmed prime mover sound will
play, and you can’t control bells, horns, etc. We recommend you to use
MRC Tech 6 power pack, [item no. 0001200], for your DC operation. It
will enable the full range of sounds on a DC system.
