Whenever I try to run
resman
without the MXI-2 cable plugged into
my PCI-MXI-2, it hangs. This also happens if I have the wrong end of
my cable plugged into the PCI-MXI-2. Why?
my cable plugged into the PCI-MXI-2. Why?
The PCI-MXI-2 uses the MXI-2 cable to find out if it is the MXIbus System
Controller. If the correct end of the cable is not securely attached to the
PCI-MXI-2, Resman and other NI-VXI applications can hang. The MXI-2
cable has a label indicating which end should be plugged into the system
controller. If you need to run Resman with the MXI-2 cable unattached, you
can force the PCI-MXI-2 to be system controller by setting the MXI
System Controller field to yes in
