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
Whenever the decoder doesn’t work please use the program track to program
CV# 125 with value 1 to restore some cv’s to factory settings. This should bring
the decoder to life with address #3. 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.
