Switching of the signal aspects

Each type N signal will be assigned one approach and one main signal address, which will be used for separate switching commands. The number of switch able speed limit aspects depends on the signal.

The signal aspects are distributed to consecutive accessory addresses:

Switch command Signal aspect for signals with ...
3 digits 1 digitno
A plus_rot Stop Stop Stop Stop
A minus_gruen 30 km/h 40 km/h 40 km/h Approach
A + 1 plus_rot 40 km/h 60 km/h Approach -
A + 1 minus_gruen 50 km/h 90 km/h - -
A + 2 plus_rot 60 km/h Approach - -
A + 2 minus_gruen 80 km/h -
- -
A + 3 plus_rot 90 km/h - - -
A + 3 minus_gruen Approach - - -

Each signal of type N occupies an 'address space' of up to four accessory addresses, which should not be used by other accessories.

The decoder will switch the signal aspect automatically depending on the command.

  • Stop at the main signal result is 'Stop'
  • Stop at the approach signal results in 'Expect stop'
  • A speed limit can be displayed for either approach or main signal
  • If there is a different speed limit for approach and main signal, the lower speed will be displayed
  • If there is no speed limit, 'Approach' is shown
  • For pure type N approach signal the red lamp will not be used. A '0' is entered as main signal address.

Setting of accessory addresses

The signal aspect generator for light signals of type N uses the following CVs for accessory addresses of main and approach signal as well as for additional light outputs:
Configuration variable Accessory base address for
Default value
CV9 / CV1 Main signal aspect 1st signal
CV551 / CV552
Approach signal aspect 1st signal 5
CV554 / CV555 Main signal aspect 2nd signal
CV557 / CV558 Approach signal aspect 2nd signal 9
CV560 / CV561 first light output 0 (= not switched)
CV563 / CV564 second light output 0 (= not switched)

Tip: For signals that are consecutive at the tracks, the main signal address of the second signal can be used as approach signal address of the first signal. Only the main signal command is transmitted. The decoder generates the correct signal aspect (approach or main signal) automatically.
