Nice Steam Tram, looks to be heavily LGB based. Sorry about the thread drift guys. Perhaps more detail in another thread please?Au contraire, mon ami. I bought mine from RCS in Oz (good exchange rate from the US,) and here's their manual:
Channel up/down buttons– Load Sensitivity. The soundcard can be programmed to make the engine loud when accelerating and softer when coasting and slowing down. The channel up/down buttons change the level of sensitivity as indicated by the number of beeps when pressed. One beep indicates maximum sensitivity. Five beeps sets minimum sensitivity i.e. the engine will be loud all the time. The default sensitivity is two and change to one if you want more sensitivity or three or more if the chuff sounds erratic.
The CH UP/DOWN works when not in programming mode - i.e. Mute not pressed, and while the loco is actually running; just as the volume controls volume while operating.
I actually sent a video link to Peter Lucas and here's the original (chuff sensitivity set to 2) You can hear the chuff sound cut out on the coasting section:
On this second video the sensitivity has been reduced.
Don't have an MLS handbook! My manual says this about button 7:
Button 7 Steam Chuff. The locomotive chuff can be generated in three ways:
1 beep Automatic chuff based on the motor voltage for two or four cylinders. (Default)
2 beeps Automatic chuff based on the motor voltage for locomotives with three cylinders.
3 beeps Mechanically triggered chuff. For locomotives which have a built in chuff trigger on an axle. The output from that chuff trigger needs to be connected to the F7 terminal on the soundcard. Note that the chuff trigger will function only when there is a voltage on the M1/M2 terminals.
My board is blue - maybe you have an old manual?
Back on track as it were I set my example up following Rik’s superb Vids and felt this needed to be acknowledged, the man is a genius.
