Labview error GPIB controller not adressed correctly

[IV-Dee]

I get this Labview error: GPIB controller not adressed correctly (LV5.1, win NT4) when i try to send data to a HP4275A LCR meter. How ever it works on an older system running with LabView 5.0 (also NT)!!!
How can I get rid of this problem????

Is the GPIB board correctly configured and is it visible in MAX? If you did an upgrade, then it installed a new version of NI-GPIB, VISA, and MAX and you need to configure the board again.

Hi,

Try using the instrument driver for the Agilent Technologies 4275A LabVIEW Plug and Play Instrument Driver as reference.

Make sure that the board is configured as System Controller (although it is the default setting).

Hi Diego, thanks for the hints!
I tried to configure (GPIB) everything standard.
when I try a 488 command initialze, I get the controller conflict, when i don't do this I get atime out problem either by 488 write-command or by 488.2 send-command.
the differences between the systems where it works and where not are:
working: Win 95, LV 5.0, GPIB-card/TNT (plug & play)
not-working: WinNT, LV 5.1, GPIB-card/PCI
i tried to set baord config to the same parameters...
on the faulti system however I see the instrument with the MAX and I can send commands, without problems !!!!
Also the driver you posted does not work (but the NI-communicate program 😉
i have no clue what else to do!
btw. how do I copy the spy output when running the program? I may provide
this to find errors.
Since MAX indicates the board is all right I guess it is not necessary to reinstall the boarddrivers?!

Hi,

The Spy capture is a good idea. You have two options to export the capture file:

- Go to Spy >> Options -> Select Log to File.

- After taking a capture, go to File >> Save as. This will save a .spy file that can be open with NI-Spy.

There shouldn't be any difference between the systems you describe. Could you also include the driver (NI-488.2) version in each system.
