I have a simple question on engine address assignments. Using the 4 digit address setup, can I assign an engine numbered 8 to a 4 digit address of 0008 or say an engine numbered 91 to 0091?
Thanks,
John
That depends on which DCC system you are using. NCE allows such an address, but some others don't.
Bachmann EZ-DCC or whatever it's called would not allow this because it accepts addresses only 1 through 9.
You'd have to read the manual for the particular DCC system in question to know the allowed range of addresses and whether or not leading zeros can be used to change a short address into a long address.
And who knows what would happen if you assign an address of 0009 with an NCE system and then try to run it on a Digitrax, because with NCE you can program CV 29 to tell the decoder that this is a long address. Digitrax may not recognize it because it may drop the first two zeros and think 09 is a short address.
Very confusticating.
Digitrax, Lenz, and CVP won;t recognize 8 or 91 as a long address. NCE can use 8 as a long OR short address, if you enter just 8, it assumes short address, 008 it assumes long address. Digitrax and NCE can use addresses 100-127 as short addresses. CVP and Lenz treat 100-127 as long.
Yes, it's very confusticating. Blame the vague NMRA standards - ALL of these schemes fit the NMRA specs as written.

Yes, it is an NCE Power Pro. I found in the instructions you can use 0008 as an address.
