Visa Timeout error -1073807339

[faqui]

Hi all together,
I have a problem trying to use Visa read, i always receive the error number -1073807339. I think the message is like this " Timeout is expired before the operation complete". What can i do to resolve the problem. I tried to built a delay time between the write and the read operation but nothing happened. I tried to reduce  the baud rate of my serial interface nothing too.
Please help me.
Thanks

You probably ask for too many bytes.
Either you do net get anything (check the value of the read buffer of VISA Read) or you ask for more bytes than your device is sending. Insert a VISA_Bytes_at_serial_port and feed thats N value to the byte count input of VISA read.

Hallo,
wie ich sehe sprichst du Deutsch. Zum Glück! Deine Antwort habe ich nicht richtig verstanden. Also der Fehler kann daher kommen, dass ich zu viele Bytes abfrage? Was soll ich also tun? Ich habe die Bearbeitungszeit erhöht und die Baud-Rate auch aber Trotzdem nichts.
Danke für die Rückmeldung.
