Unknown Hardware Error
An unknown GPIB hardware error has been encountered. The basic problem is that your hardware is not being correctly recognized by the system. Several of the possible causes for this problem are listed below:
The NI-488.2 driver for your GPIB interface failed to load correctly due to a resource conflict
Typically, resource conflicts occur when your system contains hardware that is configured to use the same resources as your GPIB interface. Resource conflicts are detected by NI-488.2 when the driver is loaded. If there is a resource conflict, the driver fails to load and records an error in the Event Viewer describing why it failed to load.
Use the Windows System Information tool to get a list of the resource usage that is known to the operating system. This utility displays a list of I/O addresses, interrupt levels, and DMA channels that are currently in use.
Once you know what resources are in conflict, run the Windows Device Manager utility to configure the new conflict-free resources.
Your GPIB interface is incorrectly installed or configured
Verify that your GPIB interface is correctly installed and configured. For information about the installation and configuration of your GPIB hardware, refer to the GPIB Hardware Guide.
Your GPIB interface appears to be installed correctly and working properly, but the NI-488.2 Troubleshooting Utility still reports this error
Try restarting your computer and rerunning the NI-488.2 Troubleshooting Utility. If problems persist, contact National Instruments for more help.
