you can use
MapTTLtrig
to configure the mainframe-to-mainframe
mapping. The NI-VXI Resource Manager automatically configures a
default mapping based on the user-modifiable configuration files. The
MapTTLtrig
function can dynamically reconfigure the TTL trigger
mapping. Only special circumstances should require any changes to the
default configuration.
MapUtilBus (extender, modes)
MapUtilBus
configures mainframe extender utility bus hardware to
map Sysfail, ACfail, and/or Sysreset for the specified mainframe into
and/or out of the mainframe. If the specified frame extender can extend
the VXI/VME utility signals between mainframes, you can use
MapUtilBus
to configure the mainframe-to-mainframe mapping. The
NI-VXI Resource Manager automatically configures a default mapping
based on user-modifiable configuration files. The
MapUtilBus
function can dynamically reconfigure the utility bus mapping. Only
special circumstances should require any changes to the default
configuration.
MapVXIint (extender, levels, directions)
MapVXIint
changes the VXI/VME interrupt extension configuration
in multiple mainframe configurations. If the specified frame extender
can extend the VXI/VME interrupts between mainframes, you can use
MapVXIint
to configure the mainframe-to-mainframe mapping. The
NI-VXI Resource Manager automatically configures a default mapping
based on user-modifiable configuration files. The
MapVXIint
function
can dynamically reconfigure the utility bus mapping. Only special
circumstances should require any changes to the default configuration.
