I tried #5 and and all functions seemed to work normally except there's no BOOST or BRAKE. All sounds were normal except no squealing brake sounds cuz the BRAKE button wasn't doing anything. I tried two different CAB1's with the same result. I then bench tested an LCRU2 bd with a Pulmor motor, and the BOOST and BRAKE worked perfect. So I hooked up the F3 again and tried #6 programming code. It seemed to work on all functions, but the BOOST and BRAKE were really funky. Mostly they didn't work at all, but then one time when I pressed and held BRAKE, all sound cutout for 1/2 second then the engine gave the startup sounds and half way thru the startup got a funky noise, then it resumed to a normal engine RPM. But I couldn't repeat that without powering off first. Another time the BRAKE function worked perfect including squealing brakes, but after that one time, I couldn't get the BRAKE button to do anything.
Any idea what the correct code might be. Here are the parts involved.
Motherboard 691-PCB1-054 Rev E
Radio board 691-PCB1-107 R2LC-08
Power board 691-PCB1-04D
RailSounds board 691-PCB1-107
Appreciate any help you can offer.
