Default Controller (LA –1)
Many NI-VXI functions use controller as a parameter with –1 accepted as
a valid value. You use this selection to determine which controller you are
referring to when you use –1 in these NI-VXI functions. Review the
descriptions of the NI-VXI functions to determine which are applicable for
this control.
By default, the Default Controller (LA –1) option is set to First remote
controller, so that any NI-VXI functions that are passed the value of –1 for
the controller parameter will be executed on the first VXI/VME-MXI-2 in
the MXI-2 chain. If you select the Local controller option, the NI-VXI
functions execute on the PCI-MXI-2.
