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 opti
-
mal 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 function 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.
Customizing Your Decoder
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.
Changing the Decoder Address
The first CV most people change is the decoder address. This allows you to inde
-
pendently 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 DT4XX series throttle. See
your Starter Set Manual for complete programming instructions.
1. Place the loco on the
programming track not to exceed 16V
. Go into
Program Mode on your system. On DT4XX throttle press
PROG
.
2. Choose AD2 for 2 digit addressing or AD4 for 4 digit addressing.
3. Choose the address you want to set up for the decoder.
4. Complete address programming by pressing
ENTER
.
Note:
CV29 must also be programmed to enable 4 digit addressing, this is done
automatically by the DT4XX throttles. See your Digitrax Decoder Manual or the
Digitrax Toolbox App for how to set up CV29.
