I’m having trouble with a 3200 & PPU setup. I’m not getting fast speed, the FSP signal from the PPU to the controller. Car runs, does single and multiple floor calls, knows it’s position, just not fast speed. Won’t come up from leveling speed. Problem is, there’s no write up about PPU signals or inter workings of it.

Does anyone know what the PPU is looking for to send out the high speed signal? Or is it likely a board issue?
