=>Can anyone in the group give a comparsion between an NEC & TCS decoder for a =>P2K SW 9 / 12. MR has an article on putting an NEC one in a SW 9 / 12, they =>say it's a plug in one but say nothing elce about it => Thanks => Malcolm
That's about all there is to say. All decoders built to NMRA standards will provide the same basic functions, and will be wired into the locomotive the same way. Some can be plugged in, if the locomotive comes with a set of plugs, others are soldered in if there are no plugs.
A decoder is basically a programmable switching device -- it switches various things on and off depending on what information ir receives from the rails. Some decoders add a few functions, such as control of sound, is all. They have few more wires because they have to turn additional circuits on and off.
To find out what a decoder can do, go to the company's website.
