8. Verdrahtungsübersicht
Die RS-422/485 PCI Karte unterstützt optional den Mode “Auto Echo”. Dies wird
eingeschaltet wenn Daten zum RS-485 Transmitter gesendet werden. Die selben
Daten werden gleichzeitig an den Receiver zurückgesendet. Die Applikationssoft-
ware kann diese Daten übernehmen um zu überprüfen ob der RS-485 Bus zur Zeit
belegt ist. Wenn nötig kann er dann die Daten nochmals senden.
