Printed in USA
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 reprogram CV67-CV94 to a default linear speed
setting.
TROUBLE SHOOTING
Loco runing without chuff sound click F12. 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. This decoder should perform well with all
DCC systems. The maximum DCC output should be less than 18 V. If the
locomotive does not respond to commands, it may have lost its address. Please
reprogram the address and program CV19 to 0 (disable consist). If it responds
slowly, you should clear its momentum by reprogramming CV3 and CV4 to 0. If
step 1’s speed is too high, you should program start voltage, CV2 to 0. 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.
