Agilent E2050A lan-GPIB gateway and Labview 6

[Paul_Britton]

I am using a system that has a E2050A in it. All the HP/Agilent lowlevel drivers are installed (SICL/VISA etc). Under Labwindows CVI everything works fine, but I need to run some Labview code, but in Labview I can't see/talk to ANY VISA resources, not even the serial ports! Has anyone managed to configure a system with this configuration successfully?

Here's a knowledge-base about using HPIB cards in LabVIEW:

Unfortunately, my question isn't about an HPIB card, it is about a HPIB-lan gateway, similar to the GPIB-ENET box that NI do.
The problem with installing HP SICL and then NI-VISA and NI488.2 is that the 'standard' NI488.2 doesn't support a 'VISA LAN client' type remote interface.
The NI GPIB-ENET box comes with NI488.2M which seems to support what I need, but unfortunately it is not available for free!!
What really puzzles me is why Labwindows CVI works, but LABview doesn't, what is the difference with the VISA access functions?

Paul:

There is a known problem with the Agilent VISA driver version J, specifically with the way it is called by LabVIEW. They have a patch for it available.

Thanks....I'll follow this lead up, and let everyone know if it resolves the issue.
Watch this space!!

Dan,
Can you give me any pointers to where I might find the patch. I've searched Agilent's support site and looked throough their IO drivers download area....could find no mention of a patch to resolve any Labview interworking issues.
