LV6.1/GPIB-PCII/Keithley 617

hi,

just found some old stuff i wanted to try out while getting to know
lv. gpib device works ok, although WinMe(card not happy with NT/2K)
did not assign DAK/IRQ, I changed this and it appears to be working
with them as well.

when i tried to connect the 617 i did find a device that did respond,
but when i dl'd the 617 drivers all i get is a unknown VISA device?

anyone got any experience with this? i could not find anything on the
subject in the lv manuals.

Hello Thor:

Thank you for contacting National Instruments!

You could find a driver for this instrument at http://www.ni.com/devzone/idnet/default.htm . If it's not listed there, it leaves you with one of a couple options. First, I would like you to submit a request for this driver at: http://zone.ni.com/idnet97.nsf/instrumentdriverrequest/
We develop drivers based on demand and popularity so the more requests we have for it, the greater the possibility that we will develop one.
If you would like to try developing your own instrument driver (or modify the existing one), we have documentation, model instrument drivers, and driver templates to help at :
http://zone.ni.com/idnet/development.htm
We also have a syndicate of third party vendors that specialize
in National Instruments' products and services. Some of the vendors specialize in driver development. I would suggest contacting one of the Alliance members at:
http://www.ni.com/alliance

I hope you have the latest GPIB driver from http://www.ni.com/support/gpib/versions.htm. If you don't follow the steps from ni.com > Support > Troubleshooting > Installation/Getting Started > GPIB.

Hope this helps. If you have any questions, please let us know.

The driver is there and I downloaded it. But after putting it in the
/inst.lib/617/ directory, I get only unknown VISA device in MAX.

Prior to this, I installed the GPIB-PCII and although it did not use
IRQ/DMA i did find an instrument that i could communicate with. Since
I was a bit unsure of the IRQ/DMA thing I forced these in winME and
the device appears to be working correctly from there and in MAX.

But when I copied the drivers in, I only
get the 'unknown VISA' and
even if i remove the drivers I'm not back where i started.

I know I should get a better GPIB (PnP with NT/2k) support, but being
1000 USD I deced to test this for fun.

Any suggestions?

Yours,

Thor Anders Aarhaug

I'm a liitle confused. Do you get the error in LabVIEW or in MAX? The driver is for LabVIEW to communicate to the instrument. LabVIEW uses the GPIB card configured in MAX to talk to the instrument via the VISA api or direct GPIB calls. If the card is correctly configued in MAX, you should be able to open Devices and Interfaces, right click on the GPIB card and select Scan for Instruments. Any instrument found, you should be able to use MAX to read and write to. Also, what version of MAX and NI.488.2 are you using? MAX 2.1 and NI.488.2 doesn't list the GPIB-PCII card as supported. If you're using an older version, you might be having a compatability problem with either VISA or GPIB driver and Win/ME. What did you use to successfully communic
ate with the one instrument?

ok, from the top:

I have LabView 6.0 installed, running MAX 2.0.3.6 and NI-488.2 driver
1.60 on Windows ME.

I installed the GPIB-PCII and windows installed it at a certain IO
adress. I set the jumpers for this IO and when I then scanned for the
instrument I found 'something that I could communicate with.'

I figured the GPIB should use IRQ and DMA so I reinstalled the card
until MAX were satisfied with it using DMA and IRQ.

I then created a ke617 folder under instr.lib and put the ke617.lib
and dir.mnu files there.

now, in MAX, i cannot find an instrument when I scan for it, and the
'unknown VISA resource' pops up.

I'll try to upgrade max and the NI-488-2 driver and se what happens.
