The update (the firmware download from the Internet is free of charge) is possible on the track when the decoder is installed (no need to open the vehicle) and can be done either via the FCC digital control unit or the programmer. If no corresponding hardware is available, the company Doehler & Haass provides a programmer on loan.

The vehicle function decoder FH18A supports braking with asymmetrical digital voltage (four diodes in series and one antiparallel diode, Lenz ABC), slow travel (with suitable brake modules) and bidirectional communication (locomotive feedback in DCC mode, RailCom®).
