Within the FREMO Projekt for an electronic absolute block I'm working at the realisation of the hardware. This relates to the interfaces at hardware level as well as the boards for the logic part - the heart of the absolute block. I also desinged a user interface and documented its construction.

Interfaces

• Station interface in relay technique
• Station simulator as counterpart for testing of block boxes
• Connector to the user interface
• Electronic station interface (optional)
  and as external links (only in German):
• Electronic block interface
• Diagnosis interface (optional)

Logic Part

• Logic part V1.0 of the electronic absolute block system
• Logic part V2.0 of the electronic absolute block system
• Order campain for kits of the logic part

User Interface

• User interface modelling a "(D)Drucktastenstellwerk relay block by Siemens" prototype
• TF71 circuit diagram

Other Stuff

• Translation of technical terms - or at least a try
• TF71 in relay tecnique of René Pabst as first implementation of the Station interface.
