KB254: DH165K0 - Function Outputs

This article was last updated on Jan. 16, 2012, 10 a.m. | Print Article | Leave Feedback

The DH165K0 is set up at the factory to control six function outputs.

The DH165K0 is configured to control the forward-headlight F0F/white lead and reverse-headlight F0R/yellow lead for directional lighting.

These two headlight function leads are current regulated for LEDs or lamps, with factory setting of approx 15mA, with no resistors required.

Cut the ADJ link to increase headlight current to approx 30mA- see fig 5.

Functions F1 (Green), F2 (Violet), F3 (Brown) and F4 (White/Yellow) are full track voltage and can be used by soldering a wire from the pad for the function you wish to use to the lamp (or other function) you wish to control.

Use the Blue + (common) pad in the middle of the F0F end of the decoder for the return connection.

The wire colors indicated are the standard color code used in the industry (you can use any color you like).

These colors are important if you plan to use function remapping.


When adding function wires, be very careful that the wires you add do not come into contact with any other pads or components on the board where they might create a short circuit.

All six function outputs can be easily set up with Digitrax FX3 lighting effects or as standard on/off functions with the following operational qualifiers:

Forward or Reverse direction of travel, or

Whether F0 is on or off, or

Both direction of travel and whether F0 is on or off, or

Whether the locomotive is stopped or moving.
