Einstellung der RS-422A/RS-485 Abschlüsse

SW 501

Wenn der Controller und RS-422A/RS-485 Buchsen verbunden sind, sollte, wie in der Übersicht dargestellt, der Abschluss entsprechend der Impedanz (des Scheinwiderstandes) des jeweiligen Übertragungsweges eingestellt werden, um Signale bei großen Entfernungen durch Kontrolle der Reflektionen auf der Leitung auszugleichen.
