Bedankt voor dat nieuws! Blij dat je er wat aan had! Veel plezier met het automatiseren. Thank you for the good news. I am happy it was of use to you. Have fun with automating your layout!
You could tell the CS3 (program) to stop a specific train, by recording a sequence of events. If you want to un-power a stop track (stop section), you'd need something like a digital relay (M-84 would be good).
I don't get the placement of digital contact track and the actual physical contact track. Don't you need to place the digital contact where the physical contact is on the layout?
The actual physical contact track is used in digital. It sends the signal (pulse) through a single wire to a "feedback" decoder, often referred to as an S-88. This feedback decoder has 16 inputs for 16 contact tracks. It adds a digital number to each input. The Central Station will get the pulse send from your contact track, and reads the number that the S-88 attached to it. It then will do the action that you have programmed in the Central Station. This action could be switching a turnout, or changing a signal etc.
That didn't answer my question. On one's track plan the contact track image should be placed on the track diagram at the location of physical contact track. However none of the videos indicate where to place the digital image. You need to clarify the placement of the digital and physical contact track.
You place the digital contact track on your track plan in the same relative location as where you have the actual (physical) contact track on your layout. Meaning: If on your layout the contact track is to the left of your actual (physical) turnout S1, you place it on your digital screen layout to the left of S1. The only reason you do it this way, is so that it makes sense to you. So that you can identify which digital image contact track corresponds with your actual (physical) contact track.
From memory, the Uhlenbrock module communicated through the "Uhlenbrock Loconet", not your regular 2 wire digital signal in use by Marklin and others. Maybe they have a module?
