kusb 488 and LABVIEW

[andreevz]

Hi,

I would like to ask you where can I download the drivers for the kusb 488?

I have just installed LabView 8.5 with NI 488.2, but now my computer cannot recognize the device connected to the usb.

First I tried with the CEC 488 drivers, but they are incompatible with NI 488.2 and I could not install them. Then I removed everything from my computer and installed a fresh copy of LabView 8.5 and NI 488.2. Then I tried to install the drivers for kusb ver 9.0 with GPIB 488, that are available at their website, but it told me they are incompatible with NI 488.2.

Thank you for the help

Drivers for Keithely devices are available from Keithley and are different than the driver for NI boards (NI-488.2). There is no reason for you to keep trying to install NI's drivers. If their driver is not compatible with NI's then you can't use the low level GPIB functions in LabVIEW. You would have to use functions that Keithley provides or use VISA functions assuming that Keithley has a VISA driver for their card. VISA is the preferred api anyway and you should be using that.

Zhelio,

The correct driver for the KUSB-488 (as well KUSB-488A, KPCI-488A) is the Keithley version 9.0 driver (called GPIB-488) which is downloadable from their website. The driver is a new release for Windows 2000, XP, Vista 32, Vista x64 compatibility.

Most important in your case, for this driver to take control, you must first remove any existing GPIB drivers (e.g. NI-488.2), then install the GPIB-488 version 9.0 driver and reboot. The 9.0 driver does support LabVIEW and does supply GPIB functions. You can also talk in LabVIEW using NI-VISA. In this case, make sure your "NI-VISA Passport for GPIB" is turned on and the older "KEVICEC Passport Library for GPIB Instrument" is turned off, if it is present. If you still have problems or questions about the driver, I would contact Keithley for support.
