NMRA CV 173 (Auxiliary Input Timer))

For decoders with an auxiliary input (WOW501 sounds can be triggered by the input. An example of this would be to install a magnetic reed switch on the bottom of a locomotive and place a magnet in between the rails before a grade crossing, then every time the locomotive approaches the crossing it will play a grade crossing quill automatically.

If the sound to be triggered is a looping sound this CV controls how long the sound will play for. The higher the value in this CV the longer the sound will play.
