I now have completed a Decoder Pro Roster File for the Rapido U25B that supports the SoundTraxx Tsunami 2 TSU-21PNEM GE #885810 Decoder. The settings would also work with the TSU-PNP8 GE #885814. This roster file will set the following function map suitable for use will all DCC systems including Digitrax: F0=Headlight (directional), Number Boards, Ground Light, Stratolite, F1=Bell, F2=Horn, F3=Short Horn, F4=RPM-/Engine Shutdown at Idle, F5=Dynamics, F6=Brakes (if enabled), F7=RPM+/Engine Start, F8=Straight to Eight & Sanders, F9=Front Class Lights, F11=Brake Select, F12=Cab Light To enable Braking Function on F6 , On the Motor Tab change CV 4 Deceleration Rate to 128, and on the Advanced Tab change CV 117 Independent Brake Rate to 116. I have set up the speed table to fairly closely copy normal running speeds on the prototype. A couple of slight wiring modifications will make the Prime Stratolite and the Engineer's Console lights work. Instructions are attached. If you want a copy of this SoundTraxx Decoder Pro roster file, let me know and I will email it to you to import into Decoder Pro. The file is named Rapido_Frisco_U25B_SoundTraxx_TSU_21PNEM8_.xml
