Programming your locomotive in the DCC
environment

DCC programming

M ost command stations currently available will program Quantum-equipped locomotives
in "Service of Ops" mode. If your command station will not program in Service Mode,
check for an upgrade from the command station manufacturer.
Configuration Variables (CV) are explained in greater detail in the National Model

Changing the system volume electronically in CV 51.0
Y ou can change the volume either manually as described in the Special Operation and
Trouble Shooting section or electronically using QSI CV 51.0 in DCC. Follow these steps to
change volume in Service or Ops Mode.
1. Enter 0 in CV 49. In Ops Mode, the value will be spoken out.
2. Enter the system volume in CV 51. The System Volume can be set to any

Follow these steps to turn off the automatic Doppler shift from a horn signal interrupt.
1. Set CV 49 to 2.
2. Set CV 51 to 0 to disable horn-triggered Doppler or set CV 51 to 1 to
enable horn-triggered Doppler.
