Ik wil voor de zekerheid nog even navragen welke ground ik moet gebruiken in <BR>
het optische multiplex verhaal.<BR>
Is dit de GND van de kast waar alle prints op aangesloten zitten of is dit <BR>
de L-GND op de IPM.<BR>
<BR>
Groetjes,<BR>

Het zal allebei wel werken, want de storingsgevoeligheid van de switch <BR>
ingangen (Sxx lijnen) is zeer laag. Uiteindelijk zitten ze toch ergens <BR>
aan elkaar. Alleen de 'normale' GND wordt gebruikt voor het grovere <BR>
werk, zoals de voeding van treinen en wissels en is daardoor theoretisch <BR>
iets meer vervuild. Voorkeur is dus de Logic-GND.<BR>
