Functions on the DH165A0
The DH165A0 is set up at the factory to control six function outputs.
The DH165A0 is configured to control the forward-headlight F0F/white lead
and reverse-headlight F0R/yellow lead for directional lighting. These two head-
light function leads are current regulated for LEDs or lamps, with factory set-
ting of approx 15mA, with no resistors required. Cut the ADJ link to increase
headlight current to approx 30mA- see fig 4.
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. 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.
CAUTION: 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 FX

lighting effects
or as standard on/off functions with the following operational qualifiers:
1. Forward or Reverse direction of travel, or
2. Whether F0 is on or off, or
3. Both direction of travel and whether F0 isonor off, or
4. Whether the locomotive is stopped or moving.

Lighting ADJ option: Cut this ‘>’ pathway for 30 milliamp applications such as
large lamps, etc. Leaving the ‘
>’ intact provides 15 milliamp outputs for LEDS
and smaller lamps (on F0F/F0R only). Other functions may require resistors!
