I would like to describe the problem and steps made to try to fix the problem without success.
I using Keithley KUSB-488B Device. We installed the latest version of the existing site http://www.tek.com/download - KI-488_Driver_Version_3.12.1.
My operating system: Win 7, 64bit.
installed KI-488_v3.12.1\NI Command Compatible Driver. Because I want to use the system interfaces with the software labview.
The Problem: Ni - Max - Not showing the GPIB Devices and
Screen shot of Ni - Max software:
According to Ni-Visa > Visa Interactive Control: can see the GPIB instrument Resources. When you move the mouse over one of the devices noted that message: GPIB0 (unknown GPIB board).
According GPIB0::12::INSTR(Keithley 6221 DC and AC Current Source) option: can sending and receiving data via Input/Output Option, work fine.
According Keithley GPIB Configuration Utility can see GPIB Devices.
According Control Panel > System > Device Manager: have Keithley KUSB-488B.
According Keithley 622x LV 2009 Labview Project(driver for device) downloaded from NI.com.
The error message i received: Error -1073807343 occurred at VISA Open in Keithley 622x.lvlib:Initialize.vi->Keithley 622x.lvlib:KE622x -- Setup DC Current Source Example.vi
the same project when i tryed to run using NI GPIB-USB-HS (when i installed his driver) work fine without any error and can see the GPIB Device in NI Max.
I tryed follow that guide:
I would do the following:
Check your c:\windows\system32\gpib32.dll file properties and see what the company and file version is....if National Instruments, for instance, then that would explain your problem.
In all events, try the following:
1. Uninstall NI-488.2 (if present). Usually this comes along when you installed NI-VISA.
To check and remove go to control panel -> add/remove programs
Look under National Instruments Software, click on change/remove and look for NI-488.2.
If present, please uninstall it.
2. Uninstall any Keithley KUSB-488A & KUSB-488B drivers
3. Remove any gpib-32.dll files from c:\windows\system32\ folder
4. Reboot system
5. Download and install the latest KUSB-488A or KUSB-488B driver from Keithley's website which is appropriate for your hardware. It is possible you have older drivers. ...btw...which device do you have??
6. After driver is installed, connect your KUSB interface and allow the device to be reconized.
If successful, the device should appear in your control panel -> system -> device manager listed as a GPIB Interface.
The guide does not solve the problem.
Asking for your help on the subject in order to solve the problem.
