Hi!
i'm using labview 6 and windows 2000.
i tried to start an serial communication by the visa vi's. but if i create a constant to the visa-ressourcename the wire is broken. the error-window shows the message: class conflict.
if i use the visa-configuration vi, the resscourcename is accepted. but the other vi's didn't accept this name.
if i download some example-vi's (loopback test for example) the wire between the ressourcename an the vi-input is broken too.
is it necessary to open a visa session in the measurement & automation explorer?

I think what you are saying is that you cannot connect a string control or constant to a VISA VI. In LabVIEW 6i that is correct. To get around this you must use either a local reference or a sub-VI to essentially cast the string to a VISA refnum. This has been fixed in LabVIEW 6.1. With this latest version of LabVIEW, you can now directly connect a string constant to a VISA VI.
In either case (LabVIEW 6i or 6.1) MAX is not required. Just drop a VISA refnum I/O control on either your LabVIEW front panel or diagram.
You may need to right-click on the VISA control and select the appropriate class for the VI that you are trying to connect to. For most operations, the Instr class is sufficient.
