Installation Notes:
1. Do not exceed the decoder’s 500mA total function output rating.
2. We recommend that the Blue wire, also Common or Lamp
Common, be connected as shown. If you wish to omit the Blue wire in your
installation, consult the Digitrax Decoder Manual for more information.
3. The head lamp should be hooked up using the Blue/+Common wire for
optimal Digitrax transponding operation.
4. To use a function output with an inductive (coil) type load, see the Digitrax
Decoder Manual for more information to avoid damage to the decoder.
5. See the Digitrax Decoder Manual for full details of wiring 12-16V lamps,
1.5V lamps, and LEDs. Lamps that draw more than 80 mA when running
require a 22 ohm 1/4 watt resistor in series with the directional light func-
tion lead to protect the decoder.
6. Some locomotives employ filter capacitors for RFI suppression in the loco-
motive wiring. These may cause problems with Supersonic decoders and
non-decoder analog operation on DCC. This capacitor should be removed
for safe operation.

Your Digitrax decoder is ready to run and will operate using address 03 with no
additional programming. For a more prototypical railroading experience, your
decoder can be customized for your specific locomotive by programming some
of the Configuration Variables, or CVs, available. See the Digitrax Decoder
Manual or the Digitrax web site for more information.

The first CV most people change is the decoder address. This allows you to
independently control each loco with a unique address. Digitrax decoders are
shipped with CV01 (AD2), the two digit address, set to 03. Following is a brief
description of how to change the decoder address with a Digitrax DT series
throttle. See your Starter Set Manual for complete programming instructions.
1 Place the loco on the programming track. Go into Program Mode on your
system. On DT400 press
PROG
. On DT300, DT100 & DT200 press
RUN/STOP
&
FN/F0
.
2. Choose AD2 for 2 digit addressing or AD4 for 4 digit addressing (DT300 &
DT400). (Ad for DT100 & DT200, see your Starter Set manual for 4 digit
instructions).
3. Use your throttle to choose the address you want to set up for the decoder.
4. Complete address programming. On DT400 press
ENTER
. On DT300,
DT100 & DT200 press
SEL
.
Note:
CV29 must also be programmed to enable 4 digit addressing, this is
done automatically by the DT300 & DT400 but not on earlier throttles.
