More about programming locomotive address on the Program Track or Main Track
To program a locomotive address involves programming a series of CVs such as CV1,
CV17, CV18, CV19 and CV29. This can be somewhat complicated. For most decoders,
Prodigy Express
2
automatically handles this for you when programming the loco address.
However, it may fail to program some old decoders and some new sound decoders
made by QSI®. It does not mean that you cannot program these decoders. It only means
you cannot use the Prodigy Express
2
’s easy address programming feature. For QSI®
decoders please refer to your decoder’s manual and use CV programming to program the
loco address. For some old decoders, you have to skip the Addr programming and use
the CV program mode to program CV29 with a value of 2 and CV1 with a short address
(1-127). Detailed steps are as follows:
1. Press Prog to select Prog Prog Track
2. Press Enter six times until CV# displays on the screen
3. To select CV29, press 29 and Enter
4. CV data displays. Press 2 and Enter
5. CV# displays again. Select CV1 by pressing 1 then press Enter
6. CV data displays. Press the loco address (1-127) and then Enter
READING LOCO’S DECODER VALUES ON THE PROGRAM
TRACK
The Prodigy Express

DCC system gives you the ability to read back CV values of
a decoder equipped loco on the Program Track. This feature is useful if you do not
remember the decoder address or what CV values your decoder has. Not all decoders
support this feature. Please read your decoder’s manual to check whether it supports this
feature. Even with decoders that support the readback CV feature, the unit may fail to
read the CV. No DCC System is able to read all decoders 100%. This should not a󰀨ect
the operation of the decoder because you are always able to program your decoder.
