What is ZN800?

Back in the '80th microprocessor based systems where introduced to track train movements. The train numbers are displayed on a computer screen or inside the control board between all the keys and indicator lamps. A signal going red triggers the propagation of a number, the feedback of turnouts determines the destination.

General Information

• Introduction by Michael Weinert (German)

Communication

• Block diagramm of the developed systems
• LocoNet protocol to display a train number
• Emulated ZLV-Bus über TCP/IP - this is the mainstream procedure
• Emulated ZLV-Bus over LocoNet and Block - so far only a thought experiment in order to get rid of the Ethernet wiring.

Komponents

• Train number displays
• User interface "EKA"/"DET"

Train describer software

• A standalone ZN800 implementation of Moritz Hebert was the first implementation (German)
• The interlocking "Elekdra" of Thomas Kurz integrates a train describer of Stefan Bormann
• The EStW-programm of Bodo Mertins integrates a train describer

Fremo

• List of stations with implementation of ZN.
