I am trying to use a LeCroy VISA passport for MAX. After installation, and given the LabVIEW examples, I can get the examples to run when the session name declares the IP address of the scope. When I add the scope to Devices and Interfaces in MAX, and I try to talk to it as an IVI logical name, it does not work. So I wonder, was I supposed to add the scope as a VISA TCP/IP Resource, or should have the VISA Passport created an additional selection for the device type (LeCroy DSO) to add to MAX?

Adding the device in Devices and Interfaces is not enough to be able to communicate with a device via IVI drivers. You need to go down the option tree in MAX to IVI Drivers. Ensure that you have a driver session that is configured to reference your Lecroy IVI driver, and ensure that you have associated your VICP hardware asset with that driver session. When that is complete, create an IVI Logical Name that references the driver session that you have created. When this is complete, you should be able to use your device through IVI drivers.

IMPORTANT: Make sure that you have saved your IVI configuration before trying to use the IVI Logical name.
I will typically double check this before trying to use my IVI Logical Names.

Hmm, I've done IVI Logical names in the past, both in simulation and with the hardware, but this one does not seem to work. Usually, the software driver tab lists out the hardware supported, but it is blank in my installation. I think LeCroy needs to add more detail to their documentation. For instance they don't say what TCP port to use, and then, their instructions say for IVI, run over to NI and down load a driver (6050 in my case). But this is the one they want you to uninstall because VISA passport is taking the place of LeCroyVISA. I suppose this is all a step in the right direction... That VICP works with both the IP address and the net name of the scope. I suppose that is a way to swap out a scope, change its net name.
