serted through the slots of the motor tabs. Squeeze the frame halves together
to hold the decoder in place.
4. Tighten the frame screws. Replace the trucks if they have fallen out during
the installation of the decoder. Place the locomotive on the track, select ad-
dress 03 on your throttle and apply power. If the motor does not respond but
you can control the lights, check the installation for motor short circuits.
5. Replace the locomotive shell. Digitrax decoders are set up with configuration
variable (CV) default values so you can run your locomotive right away using
address 03. See the Digitrax Decoder Manual for complete instructions on
setting up the CVs for customizing your locomotive’s performance character-
istics.
Note:
Motor contacts may optionally be bent to engage provided slots on the
decoders (See figure 4) Be sure to check clearance to frame after installation.
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.
