Programming DCC Locos

Ron has a question for those experienced with programming DCC locomotives:

"When trying to re-program one of my DCC Locos I keep getting message "d nA" which I understand to be an indication of an open circuit on Programming Track. I am using a 3 foot strip of track made up with E-Z Track and have dismantled and re-made it up 2 or 3 times but get the same error message. Is this a problem with the decoder in the Loco, or is it the E-Z Track? Should I use a 3 ft strip of ordinary Peco or Atlas track?"
