Lionel 691PMB2101 Powered Railsounds 4 Motherboard

Sid's TrainsOGR Forum Member

So Lionel shows they still have some of the old RS4 powered motherboards. That's fine and all , but in comparison to the err manual for the old Rail sounds commander there is a slight difference. The Lionel is missing the volume pot and instead has an extra 3 pins next to the speaker connection. My question is what is the wiring situation with the Lionel board compared to the ERR board. I am planning to buy one from Lionel and would like to the know the different wiring for the Lionel one.
