Functions:

Function Lights
Headlight and rear light changes with the direction of travel.
Depending on the locomotive type, each decoder is either equipped with up to 4 light outputs to drive the original LEDs of the locomotive housing (therefore, contact latches are already soldered on the decoder circuit board) or with on the decoder populated LEDs (these LEDs are part of the decoder circuit board and replace the light bulbs of the locomotive).
The light function can be assigned to any function key via configuration variables (function mapping). The intensity of the light is also dimmable by changing of configuration variables.

Function Low Beam / High Beam
The low beam / high beam function can be assigned to any function key via configuration variables. The intensities of low beam and high beam is adjustable. By pressing the function key, the headlight toggles between the two preset intensities.

Function Partial Light Deactivation (Preclusion)
The partial light deactivation allows to deactivate the lights at a specific end of the locomotive.
A typical situation where to apply this function is the push-pull operation. The headlights and rear lights pointing to the waggons must be switched off, but the other lights must be reversed in the direction of travel (white / red).

Function Shunting Gear
The shunting gear allows a fine speed control at low speeds. Aditionally, the shunting headlights (headlights at both sides) are powered on.
The shunting gear function can be assigned to any function key via configuration variables.

Decoder Presets:

The decoders are preset as follows:
Operating system: DCC, address 3 (short), 28 / 128 speed steps

Preset function mapping:
F0 (light) – headlight and rear light (changes with the direction of travel)
F1 – toggles high beam / low beam
F2 – deactivate headlight / backlight at driver’s cab 1
F3 – deactivate headlight / backlight at driver’s cab 2
F4 – shunting gear and shunting headlights (headlights at both ends)
