decoder function

[trainman1248]

are bachmann decoders 1 function, 2 function or 4 function

im experimenting with decoder pro

[ACY]

They are 2 function as far as I know, but I thought I read somewhere that some of the new ones on newly released products (this year) were 3 function.

The 36-552 is a 2 function decoder, the 36-553 is a 3 function decoder as is the 36-554.

OK! what is the difference between a 1,2 3,4, function decoder?
Al of mine are the Atlas Lenz or Digitrak decoders. I just use them and never thought about a number of functions.

Ken,
Decoder functions are usually associated with lighting effects, but they can control other things as  well, a smoke generator, for example.  The more functions your decoder supports, the more effects you can implement:  ditch lights, flashing strobe, cab light, and Mars light for example.  Your decoder manual will help you get a handle on how to control the functions your decider supports.  Hope this helps.
