6. Verdrahtungsübersicht

Die RS-422/485 Karte unterstützt optional den Mode “Auto Echo”. Dies wird einge-

schaltet wenn Daten zum RS-485 Transmitter gesendet werden. Die selben Daten wer-

den gleichzeitig an den Receiver zurückgesendet. Die Applikationssoftware kann diese

Daten übernehmen um zu überprüfen ob der RS-485 Bus zur Zeit belegt ist. Wenn nö-

tig kann er dann die Daten nochmals senden.
