488 DLL

[EdwardQXL]

How can it be that when I try to call this dll, located in a directory with 64 in its name, on a 64bit machine, using 64 bit LV, I get this error?  All I want to do is call ibwait.

SysWOW64 is for 32bit. It is part of a compatibility layer to allow running 32bit applications on a 64bit OS. (details)

Thank you.  Where can I find the similar dll for 64 bit?

[EdwardQXL]

On an older system I called gpib-32.dll to invoke ibwait.

I do not know how to invoke that on a newer system with 64bit LV.

[altenbach]

Did you install the 64bit drivers? (Maybe from here?)

(Sorry, I am not a hardware guy. Some others probably will com up with a more detailed solution)

Why don't you just use the GPIB Wait Function?

Reference: Serial Polling and SRQ Servicing with NI-488.2 Software and LabVIEW

GPIB Wait ( ibwait in NI-488) waits for the state indicated by a specified Status Word mask in a particular GPIB bus.

Because it is an odd situation in which which I need the PXI's GPIB card to be a device on the network rather than the controller
