The new LokProgrammer software 5.2.9 is now available for download. This includes firmware 5.10.168, 5.10.169, 5.10.172 for all LokSound 5 and LokPilot 5 decoders. This will add versatile new features to our decoders: A new auxiliary steam chuff trigger can be used to independently control a second steam motor in steam locomotive projects. We also extended the SUSI Mapping by one line to control F0 Reverse independently: This is needed for new upcoming Märklin® / Trix® H0 Tender steam locomotives to maintain the correct function of the headlights. In the same locomotives, the new light output mode (effect) "Steam trigger Edge Toggle" can be used to correctly control the synchronized smoke units. Using this firmware (and the correct settings) will allow for these locomotives to work flawlessly using an original LokSound 5 decoders offereing industry-leading sound features. Finally, we added two new SNCB signals for the SignalPilot.
