The update (the firmware download from the Internet is free) 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. The software, firmware and sound data download can be obtained from the Doehler & Haass website . If no corresponding hardware is available, the company Doehler & Haass will provide a programmer on loan.

The vehicle function decoder FH05B 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®).
