Appendix B
Troubleshooting
This appendix addresses certain problems you may encounter when using the NI-VXI bus
interface software on the AT-MXI platform. This material covers the following issues:
•
Running the VXIINIT initialization program results in an error message or causes the
system to hang.
•
Running the RESMAN Resource Manager program causes the system to hang or results in
incorrect data.
•
The mouse behaves erratically after you install the NI-VXI software.
If you encounter any of these problems, your system may have a conflict with one of the
AT-MXI configuration settings or you may have a problem with the MXIbus cable(s). For
proper operation, the AT-MXI requires the allocation of the following system resources:
•
Thirty-two bytes of I/O register space
•
At least one interrupt level that cannot be shared with another device
•
A DMA channel (optional)
•
A contiguous 64 KB block of memory space in the upper memory region of the PC AT.
The following sections discuss each of these system requirements along with the possible
problems that may be encountered with a bad MXI cable.
If you are unable to resolve your problem, please fill out the appropriate forms in Appendix C,
Customer Communication, and contact National Instruments.
Problems with VXIINIT
This section discusses what to do if running the VXIINIT initialization program results in an
error message or causes the system to hang.
VXIINIT Error Messages
VXIINIT can give you error messages that inform you that it could not find the AT-MXI, that it
could not find a specific file, or that an error occurred while writing a log file.
