Another problem...

I have a GE 70 Tonner that was purchased used.

The engine runs fine on a analog track,but does not respond to any
address on the EZ commander.
Is it possible someone assigned it to address on another dcc set up the the EZ Commander does not recognize ?

Is it possible to reset to factory address #3.

Thanks
Bob

I lost the CD that came with the original set.
I have more DCC engines than addresses now.
What is the procedure for assigning 2 engines to the same address
tail to tail ?
Thanks Bob
