??? I have a bachmann gp30 Reading Lines. I have tried running it on address code 03 and have had no luck. I use digitrax control. I put this unit on my program track and it reads d n d. What must I do to get control of this unit?
Assuming your locomotive has a decoder that was factory installed, try the cab number of the locomotive. Decoders are shipped set to address 03 unless they are installed in a locomotive. Then they are often set to the locomotive cab number.
From the DND reading, I assume you are using a Zephyr, either the DCS50 or the DCS51. This command station has troubles reading back certain Lenz type decoders unless you connect a 1000 ohm resistor across the rails of your programming track. This again assumes a factory installed decoder.
