SELECTING A LOCOMOTIVE OR

CONSIST

First a word about locomotive addresses. A decoder can have 2 different addresses,
the Short Address (values from 1-127) and the Long Address (sometimes called 4
digit with a range of 0000-9999). A decoder can use one or the other but not both at
the same time. Some entry level decoders can only use the Short Address.

As you can see above there is an overlap in the address ranges between the short
and long address. You can have a Long Address of 6 and a Short Address of 6.
They are not the same. To use a short address (range 1-127) it is selected on the
cab by entering only the significant digits (no zeros before you get to the numbers).
To enter a long address in the range of 0-127 put a zero before the digits. A long
address between 0 and 127 will have an asterisk (*) before the loco address on the
cab display as below:

LOC:*006 2:00PM

ENTER LOCO: _

NOTE: You will notice that the short address 0 is not available but the long address 0
is listed as a valid address. Short address 0 is the “broadcast” address for DCC. If
you were to send commands to short address 0 all locomotives on the layout would
respond causing chaos. For this reason we don’t allow use of short address 0. Long
address 0 can be used just like any other locomotive address.
