Dave,
Yup, I ran into that early in my VEE career, chased my tail for days as I remember.

Doug,
 
Another thing to remember, make sure that there are no instruments using the same address as the bus address (i.e. 1414, 1515, 707, etc.)  This has been known to cause problems.

Hey Joe,
Thanks a million, that fixed it. I should have thought of that to begin with, but it’s working now, so I won’t complain. Once again the vrf makes me look like a star!

You might try the standard address as 15xx (xx=instrument).  I have noticed NI cards at GPIB0 are 14xx, 1 is 15xx, etc,
 
Best regards,

Greetings all,
I’ve got a sticky problem; I’m hoping some of you have already seen it and figured it out. We just got a National Instruments Ethernet GPIB interface. I ran the installation wizard from the NI software and got the thing configured. NI MAX sees the interface and the one instrument I have connected to it. Agilent I/O libraries connection expert sees the interface and the instrument. I just can’t get VEE to deal with it. One interesting thing was that when I added the interface, it installed itself as GPIB1. I had never seen a National interface that did that. There is no other interface installed on this system, so I assumed it would be GPIB14 like always. So, I went in and changed the name to GPIB14. NI MAX still has no trouble seeing the interface and instrument, even recognizes it as GPIB14. Agilent connection expert however, shows a communication error, but it does know what instrument is connected. The strange part in VEE is that when I use a Direct I/O object just to read the *IDN string, I get an error saying configuration error, cannot open GPIB0 on National card. Anybody seen this, or am I just missing something simple?
 
Thanks in advance,
 
Doug Rudrow
