What are CVs for?
With CV settings you can change the behavior of vehicles as well as the functions.
- Speed / Speed curves
- Acceleration and braking
- Lights (permanent, switching options, etc.)
- Blinking rhythms (turn signals, blue lights, headlights)
- Functions: Fire_engines_automatic, Bus automatic, Light sensor, Reed switch, etc.
- Feedback battery test, code messages (DC-Car-XT), etc.
The values can be changed using:
For some values, multiple functions can be selected.
The individual values are added together.
e.g. CV27 1 battery test switch off + 2 light sensor switched off: enter value = 3

Caveat: If you have changes to many settings and you do not know what to do, first, carried out a RESET though (CV59 = 3) are .>br>
With just a few CV changes the behavior of a DC-Car's is extremely variable.
For this purpose, either a Progset is required which connectes to a digital station, communication is done via IR sensors at the front or
a CV-Programmer which communicates through the Update connector with a PC using the free CV programmer software.
There are settings for:
- Operation e.g. Lights interconnect, servo operation
- Behavior, for example, Braking, accelerating, flashing light timing
- Technical Settings e.g. Battery test, trailer connected
- Technical settings e.g. Address, DC-Car-Booster, PC-Transmitter
The most important are listed her:
|CV1||Technical Setting Address up to 127|
|CV2||Slowest speed for speed step 1|
|CV5||Fastest speed for speed step 28|
|CV19||Soft braking and accelerating (from May 2013 software)|
|CV20||Activate towing and IR feedback|
|CV21||Activating receiver for DC-Car-Booster or DC-Car-PC-Transmitter, Servo operation|
|CV24||Lights permanent switched on, Headlights, Blue lights|
|CV27||Technical Settings Reed switch, Battery test, Light sensor etc.|
|CV28||Define battery test voltage settings:|
|CV29||Usage of long or short address|
|CV48||Braking by preceding vehicle|
|CV53||Acceleration in the lower speed steps|
|CV54||Acceleration in the upper speed steps|
|CV60||Light outputs 2, 3, 4 for driving light|
|CV69||Start after power on|
|CV98||Timing +2 or -2 speed steps|
|0 = General|
1 = Lorry short
|CV111||Hall sensor activated 1 or 123 with Light 2 active at the stop|
Multiple values common benefit
If there are multiple values for a CV these are added.
Bit values means calculating together:
If several settings are possible at a CV, the "bits" are added.
e.g. in CV24 (or CV59)
- Light Sensor OFF = 1
- Battery Test OFF = 2
Together makes a value 3 plus
- Reed switch disabled = 8
adds up to 11 as the value of this CV
In the CV-Programmer with the software for this purpose several fields are simply marked. The summing up the program does.
At the same time it checks for conditions. This can result in:
- A vehicle decoder is not suitable for this CV value -> Update required.
- The CV-Programmer software is not up to date and provides the opportunity not. (Update required -> The current CV-list ahead of the software always a few weeks.)

Note: A second "bus" still responds to the distance signal!

Activating the battery test
|CV27||0 or 1|
|CV28||3,6 Volt with a diode 130|
|CV28||2,4 Volt 120|
|CV28||1,2 Volt 55|
|CV19||0 Vehicle drives with speed step 28, blinks with headlights and brake lights|
|CV19||16 Vehicle stops and blinks with headlights and brake lights|
The values are best determined experimentally.
If the value is too high, the brake lights and the headlights go already on slopes or tight corners.
If it is too low, there is no "battery alarm".
CV19=0 : Vehicle is traveling at constant light. The battery is below the limit.
Light goes out. Since this increases the battery voltage again no further "light switches". The vehicle starts without further light.
CV19=1 : it may happen that the vehicle stops and the battery recovers.
If the voltage is again high enough, the car jerks ago.
