MAX-made IVI sessions seemingly ignored by LabVIEW

[ALICE HMPID at CERN]

We run LabVIEW 6.1 under W2000 with all the latest updates installed, using a PCI-GPIB NI-488.2 card; IVI Compliance Package 2.0. Even though we have set our device (a LaCroy LC564A oscilloscope) up with MAX, LabVIEW seems to ignore our settings - the IVI resource I/O constant is always empty and all attempts to run our application in non-simulated mode (and sometimes in that too) result with errors (many different ones but all mentioning the resource cannot be resolved). The hardware has been checked and works well, using the same hardware asset as a VISA resource gives no problems whatsoever.

Hi Alice,

The first thing you need to check is the IVI class of the control. Right click on the IVI control and go to "Select IVI Class". If you are using class drivers you need to configure a logical name, select the appropriate IVI class. If you are using a specific driver, select it from the class submenus. The IVI control will be populated with the VISA resource descriptors.

Hope this helps.
