• Ist die Verbindung nicht korrekt, erscheint auf dem Bildschirm die Anzeige "No
Connection"
Mögliche Ursachen:
1. Die serielle Schnittstelle ist bereits durch ein anderes Programm/Gerät belegt. Der
IRQ darf nicht gleichzeitig von 2 Geräten genutzt werden. Schließen Sie die ande-
re Anwendung, bzw. benutzen Sie evtl. die zweite serielle Schnittstelle. Starten Sie
den Computer und die TestLink Software neu.
2. Das Schnittstellenkabel wurde nicht in die RS232 Buchse (11), sondern in das Sig-
nalausgangsterminal (12) gesteckt.
