searching for driver for HP-E3641 (power supply) on Win98

aviad frydman · ‎08-02-2000

hi,
I'm using the above menssioned power supply on a Win98 machine but lack the
right driver for it. the NT and Win95 drivers crash LabView.
doe's anybody know where I can find it?

many thx, avshi

If you downloaded this driver from NI's site then you have an IVI driver.
Make sure you have all the components installed for IVI. If you have an older
version of LabVIEW, you'll either have to upgrade or find a "classic" LabVIEW
driver or modify one for a similar instrument.

Odd- as far as Labview's concerned 95 should be identical to 98 in what
functionality is available. If you post a URL to this program, people could
have a nosey and see why it crashes, since that certainly shouldn't happen.

I assume this is a bog standard VI that drives the instrument via
GPIB/serial/VISA and not some DLL driving a proprietary interface?

well, it is a standared VI that I downloaded from NI, but going into the
code it seems that every call the the power supply is done via a DLL
(included in the downloaded package). the crash occures inside the DLL.
actually I'm not sure whether the reason is the OS platform. do you know
of any other reason for a crash to happen when calling a DLL?

thx, aviad frydman

I don't have any direct knowledge of this driver but here are a couple of
things
I do know.
1) This is probably based on what HP (agilent) calls a UID (universal
instrument driver)
This is the reason it has DLL call. The UID was converted to Labview using the
Convert CVI FP

2) If you use the Win95 driver it should work in Win98 (I say SHOULD).

3) I
f all else fails look on the agilent site for the UID for this instrument
(good luck searching)
and do the conversion yourself.

These UIDs are supposed to be capable of being used in LabVIEW, LabWindows ,
HPVEE and text code.
I am always annoyed when I get drivers that are built this way, so I usually
trash them and "roll my own".

Hope this helps

BTW I know a UID for the 3631 exists, it may be useful.
