Installation. Missing Board in Device Manager If the National Instruments CAN Interfaces item exists, but the CAN interface you are looking for is not listed there, the interface is not properly installed. For National Instruments CAN hardware, this problem indicates that the interface is not physically present in the system. -
Page 51: Problem Shown In Device Manager
Code 8: The NI-CAN software was incompletely installed. To solve this problem, reinstall the NI-CAN software for Windows 98/95. Code 9: Windows had a problem reading information from the interface. Contact National Instruments for assistance. © National Instruments Corporation PXI-846x and NI-CAN for Windows 98/95... - Page 52 Appendix F Troubleshooting and Common Questions Code 12: Your interface was not assigned a physical memory range. If your computer does not have 8 KB of available memory, Windows might configure your interface without a physical memory assignment. The NI-CAN software cannot function without 8 KB of physical memory. Another way to verify this problem is to look at the Resource settings list on the Resources tab to verify that the interface was not assigned a Memory Range.
