Configuring (programming) decoder settings 63
When you use "Programming on the programming track" it is not
necessary to know the address of the decoder. The decoder receives
a command like:
"Write value 15 in CV4!"
Each and every decoder that receives this command will carry it out.
13.1.2 When to use "Programming on the programming track"?
Whenever you want to change the address of a locomotive
decoder.
®
There are also Digital plus by Lenz decoders that are not capable
of "Programming in operational mode", e. g. locomotive decoders that
were developed before this feature became an NMRA standard, or e.
g. switch decoders that do not need this functionality (because these
receivers can be fully configured before being installed).
For all these decoders you must use "Programming on the
programming track".
