8.2 DCC Address Ranges & Display
There are three address ranges available for addressing and programming loco-
motives. You can use all three address ranges at any time and in any combina-
tion you choose.
Address 00:
The analog address used to run locomotives without
decoders. All analog locos on the layout will respond to the speed
and direction commands issued to address 00.
2 digit addressing:
Addresses in the range of 01 through 127. Also
called short addressing. 2 digit addressing can be used with any
DCC decoder.
4 digit addressing:
Addresses in the range of 0128 to 9983. Also called
Extended Packet Format or long addressing. Four digit addressing
can be used with any DCC Extended Packet Format, or EPF,
decoder that supports this four digit addressing. The decoder must
also be set up to enable 4 digit addressing.
The DT400 does not support aliasing of 2 digit addresses.
When the DT400’s LCD displays a 2 digit (00-127) address, only the 2 or 3
digits of the address will appear in the display. When the LCD displays a 4
digit address (0128-9983), all four digits including any leading 0s will be dis-
played. Example: 127 is a 2 digit address and the display will read 127. 0128
is a four digit address and the display will read 0128.
8.3 Selecting An Address On A Throttle
1. Choose which Throttle (L or R) you want to use to run a locomotive.
Make it the active throttle by turning it a 1/4 turn in either direction
or by single clicking the throttle knob. If there is an address selected
to the throttle, the smoke icon will be blinking.
2. Press the LOCO Key
. The active throttle display will begin flash-
ing the Loco Icon, the last loco address selected on the throttle and
the Lo mode indicator. The Text Area of the display will show the
status of the last loco address selected (usually “stat 128” for
Digitrax decoders). “Sel Loco” will be displayed in the Text Area if
no loco address was previously selected.
3. To select a 4 digit address, use the numeric keypad to key in the
address of the loco you want to run OR use the L Throttle knob to
dial up the first two digits (1000s & 100s) of the address you want
to select and use the R throttle knob to dial up the last two digits
(10s & 1s) of the address you want to select. Alternately, you can
