17.0 Programming Configuration Variables (CVs)
The decoders installed in your locomotives provide you with the ability to cre-
ate a more realistic operating experience through the configuration variables
(CVs for short). The DT402 series throttles support configuration of up to
1024 CVs!
It is a good idea to run your decoders with the default CV values that come
pre-programmed in your decoders until you get used to the performance char-
acteristics and how they work on your layout. Once you are comfortable with
running the trains, then you can begin customizing loco characteristics.
Each CV (configuration variable) controls a specific characteristic of the
decoder, which in turn controls how the locomotive performs. See your
decoder manual for a list of the most commonly used CVs and their meanings.
Each decoder comes pre-programmed from the factory with the default settings
outlined in your decoder manual. You can change your decoder’s performance
characteristics by changing the CV values entered in the CVs you want to
change. Each of these CVs can be set up when your command station is in the
programming mode. The CVs are remembered in the decoder until it is repro-
grammed to with a different CV value. Please refer to your Digitrax Mobile
Decoder Manual for a complete listing of the CVs supported by each decoder.
Important Note on Programming
:
Programming decoder CVs is most commonly and easily done on an isolated
programming track and the following examples use that method.
See
Section 6.1 for details on setting up the programming track.
Simplex Radio and infrared throttles must be plugged into LocoNet to program
CVs on the programming track. Ops Mode Programming can be done without
plugging simplex radio throttles into LocoNet. IR throttles must be plugged in
for Ops Mode Programming. Duplex throttles can program without plugging
in on both the programming track and in Ops mode.
