3.0 Decoder Installation

Each Digitrax decoder comes with an instruction sheet that shows you the spe-

cifics of how to install it in a locomotive. There are also additional installation

application notes and installation videos available at www.digitrax.com/sup-

port. The following sections explain decoder installation in general.

3.1 Decoder Installation Basic Steps

1. Choose a locomotive that runs well on regular DC because adding a

decoder will NOT improve mechanical operation.

2. Choose the appropriate decoder for your installation.

3. READ the instructions.

4. PLAN the installation.

5. Have the proper tools on hand.

6. Test the decoder before installation.

7. Carefully disassemble the loco without losing any parts.

8. Isolate the motor! Current to the motor from the pick ups should

flow only through the decoder and NOT through the frame.

9. Follow the decoder’s wiring diagram or installation instructions for

installing motor, sound and function components.

10. Test the installation first on DC then on DCC.

3.2 Choosing a Locomotive

Choose a locomotive that runs well on conventional DC power. Digital

decoders don’t compensate for faulty motor operation, poor track pickup, or

other problems with a locomotive’s mechanical operation. If you are not happy

with the way your locomotive runs on DC power, installing a decoder will not

make it run any better.
