PXI-8461 or PXI-8460 and NI-CAN for Windows 98/95 D-4 www.natinst.com
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. To solve this problem, free up an 8 KB
Memory Range (such as
D0000 to D1FFF hex) that is being
used by another device in the system.
Code 15: Your interface was not assigned an Interrupt Request level. If
your computer does not have any available Interrupt Request
levels, Windows might configure your interface without an
Interrupt Request level. The NI-CAN software cannot
function without an Interrupt Request level. Another way to
verify this problem is to look at the Resource settings list on
the Resources tab to verify that your interface was not
assigned an Interrupt Request level. To solve this problem,
free up an Interrupt Request level that is being used by
another device in the system.
Code 22: Your interface is disabled. To enable your interface, check the
appropriate configuration checkbox in the Device Usage
section of the General tab.
Code 24: Your interface is not present, or the Device Manager is
unaware that your interface is present. To solve this problem,
select your interface in the Device Manager, and click on the
Remove button. Next, click on the Refresh button. At this
point, the system rescans the installed hardware, and your
interface should appear. If the problem persists, contact
National Instruments.
Code 27: Windows was unable to assign your interface any resources.
To solve this problem, free up system resources by disabling
other unnecessary hardware so that enough resources are
available for your interface. The resources required for a
single interface are an Interrupt Request level and an 8 KB
physical memory range (such as
D0000 to D1FFF hex).
