Bit 1

Headlight mode:

1

 

 

 

 

0 = Operation with 14 or 27 speed-step

 

 

 

 

 

 

systems. This setting must be selected when

 

(2)

 

 

 

 

the locomotive decoder is used with any

 

 

 

 

 

DCC system that does not support the 28

 

 

 

 

 

 

speed-step mode. If the headlights turn on

 

 

 

 

 

 

and off as the speed is increased, the

 

 

 

 

 

 

command station is configured for 28 speed-

 

 

 

 

 

 

steps, and the decoder is set for 14 speed-

 

 

 

 

 

 

steps.

 

 

 

 

 

 

1 = Operation with 28, 55 or 128 speed

 

 

 

 

 

 

steps. If you use this setting, the Command

 

 

 

 

 

 

Station must also be configured to use either

 

 

 

 

 

 

the 28 speed-step mode or the 128 speed-

 

 

 

 

 

 

step mode; otherwise, the headlights cannot

 

 

 

 

 

 

be controlled.

 

 

 

 

 

Bit 2

Usage on conventional DC layouts:

0,1

1

 

 

 

 

0 = locomotive operates only in digital (DCC)

 

 

 

 

 

 

mode

 

(4)

 

 

 

 

1 = locomotive can operate in either analog

 

 

 

 

 

 

(conventional DC) or digital (DCC) mode

0

 

 

 

 

0 = Factory-default speed curve is used

 

(16)

 

 

 

 

1 = User-defined speed curve is used.
