er with the origi-

nal screws. Note:

the locomotive's

frame halves

may have to be

loosened slightly

to achieve proper

alignment.

CAUTION: When

attaching headlight

wires, be very careful

that the wires you

attach do not come

into contact with any

other pads or com-

ponents on the board

where they might

create a short circuit.

Installation Notes

Do not exceed the decoder's 500mA total function output rating.

We recommend that the Blue wire, also called +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.

The head lamp should be hooked up using the Blue/+Common wire for opti-

mal Digitrax transponding operation.

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.

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.

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.
