PROGRAMMING
This decoder supports all program modes and read back features.
With MRC
Prodigy Advance DCC you can read its address and CV value.
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 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 21 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 to 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.
