Unknown Hardware Error
An unknown serial 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-Serial driver for your serial 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 serial interface. Resource conflicts are detected by NI-Serial 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.
Determine the resource that caused the conflict and select new resources that are not in conflict.
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 and interrupt levels 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 serial interface is incorrectly installed or configured.
Verify that your serial interface is correctly installed and configured. For information about the installation and configuration of your serial hardware, refer to the Serial Hardware and Software for Windows Help.
Your serial interface appears to be installed correctly and working properly, but the NI-Serial Troubleshooting Wizard still reports this error.
Try restarting your computer and rerunning the NI-Serial Troubleshooting Wizard. If problems persist, contact National Instruments for more help.
