3.22 Special Effects for Function Outputs
(US and other lighting effects, smoke generators, uncouplers etc.)
Special effects can be assigned to a total of 10 function outputs with
CV’s #125, #126, #127 … #132, #159, #160
for F0fr., F0rear. FO1 ...... FO6 , FO7 , FO8
The values for these special
effect CV’s contain the
actual
6-Bit special effects code
and the
2-Bit directions code

The effect-

direction dependent function outputs
without using a special effect
(with effect code 000000).
EXAMPLE:
CV #127 = 1, CV #128 = 2, CV #35 = 12 (FO1, FO2 operate directional, ON/OFF with F1 key).

ATTENTION in case of CV #125 and #126: change

EXAMPLES
You want : Program CV #125 to:
Mars light forward only - 00000101 = 5
Gyralite independent of direction - 00011100 = 28
Ditch type 1 left, only forward - 00100101 = 37
Uncoupler - 00110000 = 48
Soft start of output - 00110100 = 52
Automatic stop light - 00111000 = 56
Automatic cab light OFF - 00111100 = 60
Speed/load depen. smoke - 01001000 = 72
Speed/load depen. diesel smoke - 01010000 = 80

Note to ditch lights: Ditch lights are only active when headlights and function F2 (#3 on Zimo cab) are on, which is prototypical for North American railroads. The
ditch lights will only be working if the applicable bits in CV #33 and 34 are on (the definition in CV #125 - 128 in itself is not enough but a necessary addition).
Example: If ditch lights are defined for F1 and F2, the bits #2 and 3 in CV #33 and 34 have to be set accordingly (i.e. CV # 33 = 13 (00001101), CV #34 = 14
(00001110).
