Decoders with wires provided for hooking up the decoder in the locomotive.  If wires are not provided for hooking up functions, solder pads are provided to allow you to access those functions by adding wires. 

Digitrax Mobile Decoder Wire Colors

Note: DH82 & DN92 decoders, some of the very first decoders produced by Digitrax used a different wiring color code.  Please check decoder spec sheets for the wire colors that were used with these decoders.

4 function decoders support F0 Forward and F0 Reverse, F1 & F2.  This allows for reversing headlights and two separate functions OR 4 separate functions if reversing headlights is not used.

Most Board Replacement decoders have LEDs for forward and revese lights wired to F0 Forward and F0 Reverse. They have solder pads for additional functions that must be wired by the end user.

How functions are numbered:

F0 (FWD) White

F0 (REV) Yellow

The Blue wire is Lamp Common to allow for continuous lamp operation.

F1 Green

F2 Violet

F3 Brown

F4 White with Yellow Stripe

F5 White with Green Stripe

F6 White with Blue Stripe

F7

F8

F9

and so one are each counted as one function.  This is an industry wide convention.

Standard functions turn functions on and off. Many Digitrax decoders with standard functions offer head lights that can be set up to be either automatically reversing or individually controllable.  Digitrax decoders are shipped with automatic reversing head lights enabled.  When you are using a standard function output, simply hook up the function output to the function device and you will be able to turn it on and off from your throttle.
