Interfaces are numbered beginning with zero. If you delete an interface,
the NI-FBUS Interface Configuration utility renumbers all the remaining
interfaces. For example, if you delete
Board0
, it appears that you deleted
the last interface, because all the remaining interface numbers are
decreased by one automatically.
Run the NI-FBUS Interface Configuration utility once to make sure the
interface has been removed.
To reinstall the interface, refer to the installation and configuration
instructions earlier in this chapter.
Note
If one USB-8486 is unplugged and you want to use other interfaces in the system,
delete this USB-8486 from the Interface Configuration Utility before running the NIFB
process.
