DCC Programming
Most DCC command stations currently available will program Quantum equipped locomotives in Service Mode
37
on a programming track or
Operations (Ops) Mode on the main track. In Service Mode, your locomotive (if queried) will report back CV values to your command station. In
Ops Mode, reports are verbal using the locomotive sound system.
Changing the System Volume Electronically in CV 51.0
You can change the volume either manually (as described in the
Special Operation and Troubleshooting section) or electronically using QSI CV
51.0 in DCC
38
. To change volume in Service or Ops Mode, do the following:
Set CV 49 to 0.
39
Enter the System Volume in CV 51.
The System Volume can be set to any value between 0 (no sound) and 127 (100%). The default
System Volume is 127.
Note:
When you change the System Volume in Ops Mode, you will immediately notice the change in volume.
Changing the Mute Volume Electronically in CV 51.1
To change the Mute Volume in Service or Ops Mode, do the following:
Set CV 49 to 1.
Enter the Mute Volume in CV 51.
The System Volume can be set to any value between 0 (no sound) and 63 (100%). The default
Mute Volume is 0.
Note:
When you change the Mute Volume in Ops Mode, and the locomotive is muted, you will immediately notice the change in Mute Volume.
Note:
The Mute Volume level will be the smaller of the Mute Volume setting or one-half the current System Volume. In other words, the Mute Volume will
never be more than one half of the System Volume.
Enable/Disable Doppler Shift from Whistle Signal Interrupt and Enable/Disable Turbine/Diesel Transition from Coded Horn (CV 51.2)
Set CV 49 to 2.
Set CV 51 to the value indicated in the table below. An “X” in the table indicates that the feature will be enabled. The default is 3 (both
features are enabled).

Changing Individual Sound Volumes (CV 52.X
40
)
To change the volume of individual sounds listed in the table below do the following:
Set CV 49 to the Primary Index for the individual sound from the table below.
Enter Volume level in CV 52 as follows: “0” = No sound, “1 – 15” = Sets volume from the lowest value at “1”, the highest volume at
“15”. The volume levels are in 2db increments.

If your DCC command station will not program in Service Mode, check with the command station manufacturer; some companies will give you a free upgrade. Also, see Special
Operation and Troubleshooting on page 25.
38
System Volume changes in DCC also apply to Analog and vice-versa.
39
In Ops Mode, you will hear the value spoken out when changing the value of a CV.
40
‘X’ refers to the value in column 1 of the table, the Primary Index number put into CV 49.
