I bought two spectrum sets with DCC On Board, The Frontiersman and the explorer. The DCC controller I have is a MRC Prodigy Advance2., Both Locos are set at address #3 and both respond to this address. I am trying to change the address on one of the Locos so I can run them independently on the same track. I followed MRC's instructions, and can't change the address and Bachmann gives no info on the decoder, so what to do for the answer. Go to Bachmann or MRC for the answer?
