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
Range
Default
CV29 to 50 for long addresses (128-9999) to enable speed table control. Then
1-127
3
select throttle to 28 speed steps and run your loco at speed step 1. Use program
0-32
0
CV on the main to change CV67's value (1-255) to adjust step 1's speed. The
0-32
0
kick voltage, CV65 is only applied when the speed step changes from 0 to 1. You
0-32
0
should switch between 0 to 1 many times to check step 1's speed. When done
0-32
32
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
0-2
0
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
---
2
also disable the speed table and re-program CV67-CV94 to a default linear
---
32
speed setting.

TROUBLE SHOOTING
192-231
192
This decoder should perform well with all DCC systems. The maximum DCC
0-255
3
output should be less than 15 V. If the locomotive does not respond to com-
0-127
0
mands, it may have lost its address. Please re-program the address and program
---
0
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
0-1
1
voltage CV5 to 31. You should also clean the track to improve electrical pickup.
