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
Range Default
control speed (motor voltage). It allows you to setup each speed for all 28 speed
1-127 3
steps. First, program CV29 to 18 for short addresses (1-127) or program CV29 to 50
0-63 10
for long addresses (128-9999) to enable speed table control. Then select throttle to
0-63 0
28 speed steps and run your loco at speed step 1. Use program CV on the main to
0-63 0
change CV67's value (1-255) to adjust step 1's speed. The kick voltage, CV65 is only
0-63 63 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
0-1 0
and program CV68. CV68's value must be greater then CV67's. When done with
--- 2
CV67-CV94, use read back CV to make sure their values are in increasing order.
--- 0
Note: When using MRC Prodigy DCC to program addresses it will automatically disable
--- 143
the speed table (set CV29's bit 4 to "0"). Programming CV125 to 1 will also disable the
192-231 192
speed table and re-program CV67-CV94 to a default linear speed setting.

TROUBLE SHOOTING

0-127 0
Loco running without any sound press F12, no chuff sound, press F6.
--- 0
Whenever the decoder doesn't work please use the program track to
0-1 0
program CV #125 with value 1 to restore the decoder to factory settings.
0-1 0
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
0-1 0
18 V. If the locomotive does not respond to commands, it may have lost its
0-16 16
address. Please re-program the address and program CV19 to 0 (disable consist).
0-3 0
If it responds slowly, you should clear its momentum by reprogramming CV3 and
0-15 12
CV4 to zero. If step 1's speed is too high, you should program start voltage, CV2
0-3 0 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
0-15 12
learn how to program and operate the decoder. For more information about
0-50 3
registers/CVs and their functions, please refer to the NMRA DCC Standard &
0-15 12
Recommended Practices, RP-9.2.2. This is available directly from the NMRA or
