Special Case - using a Lenz 10231-01 Standard as a function decoder
What is the difference between the "locomotive decoder mode" and the "function decoder mode”?
In the operating mode "locomotive decoder”, the motor outputs of the decoder respond to the information on the speed steps and the direction of travel.
In the operating mode "function decoder”, the motor outputs do not respond to the speed step, but to the function entered into CV49, depending on the direction of travel. The factory setting of this value is 0, i.e. the motor outputs respond to the function 0. This is typically the light function.
In the function decoder mode, the motor outputs change the polarity depending on the direction of travel, so that LEDs with series resistors switched in parallel can be connected to the orange and to the grey cable. In this operating mode, the motor output is dimmable; the corresponding dim value is entered into CV120. The factory setting of this value is 255, "not dimmed” Thus, in the function decoder mode, functions can be connected to the motor outputs of the decoder (grey and orange cable) which are to respond depending on the direction of travel. A typical example of such a function is a control car with direction-dependent front light.
The software version required for the function decoder mode can be found in CV7 or CV128.
How is the function decoder mode activated?
To activate the function decoder mode, set Bit 5(4) in CV50.
For safety reasons, this change can be carried out ONLY on the programming track. This setting is NOT changed by resetting the decoder to the factory setting (CV8 = 33), i.e. all factory settings EXCEPT the above- mentioned bit are reset. Resetting to factory settings does not change the operating mode.
From which software version of the Standard+ and SILVERmini+ is the function decoder mode available?

Control cars with direction-dependent light changes are normally designed so that in analogue mode the direction-dependent switching of the lighting (white/red) is done automatically via the applied polarity. Depending on the polarity, the white or red light is activated: If in forward direction the positive pole is located on the right track, the white light is activated, if the negative pole is located on the right track, the red light is activated.
To facilitate the conversion of such control cars, in the "function decoder mode" the motor outputs of the decoder are set so that the decoder can be switched simply between the rail pickups and the electronics of the control car.
