You can change the decoder address by reprogramming it at any time so, you
can set up any numbering scheme you choose for your locos. Many people
assign the last two numbers of the loco’s road number as the 2 digit decoder or
4 digits of the road number as the 4 digit address.
More than one loco can be programmed to the same address. This is useful
if you want to set up a basic consist and run more than one loco on a single
address.
Digital Address Ranges for Mobile Decoders
Address “00” is used for analog operation of a locomotive without a decoder
on the same track as DCC equipped locos.
Addresses from 001 to 127 are the two digit address range. Two digit decoder
addresses are set up by programming CV01 & CV29.
Addresses from 0128 to 9983 are the four digit address range. Four digit
decoder addresses are set up by programming CV17, CV18 & CV29.
There is no “three digit address.” If your loco only has a three digit
road number, you can use 0-127 as a 2 digit address or use a 4 digit
address with a leading 0.
7.1.1 Decoder 2 Digit Address: CV01
On your DT300 & DT4xx throttles,
the display will show Ad2 for two
digit addresses and Ad4 for four digit
addresses. All other CVs are displayed
as numbers on Digitrax throttles. Be
sure that CV29 is programmed to a
value that enables 2 digit operation.
See CV29 below for more information.
7.1.2 Decoder 4 Digit Address: CV17 & CV18
The 4 digit address is sometimes called the long address. It is programmed in
CV17 & CV18. Simply programming CV17 & CV18 will not enable 4 digit
addressing. The DCS50, DCS51, DB150, DCS100 & DCS200 Command
Stations that come with Zephyr Series, Super Empire Builder Series and Super
Chief Series Sets provide automated programming that makes this process
simple. See the starter set manuals for step by step instructions for setting up
and enabling 4 digit addresses in your decoders.
