Using a Loco address in an Accessory Decoder
Locomotive decoders and some accessory decoders can be uniquely configured by the use of Configuration Variables called CVs. The DCC standards allow a locomotive decoder CVs to be programmed when it is operating on the main track. This is called Operations (Ops) mode programming or On the Main programming. Each loco decoder on the track can be programmed using it's unique address.

Current Team Digital accessory decoders have a feature that allows Ops mode programming. They have a Locomotive decoder type address. Using this address the accessory decoder can be programmed just like a Loco decoder. As mentioned above the Loco (Ops) address can be the same as one of the accessory outputs with out a conflict.
