Note
T&M Explorer includes special settings that you must use for low-level functions
and memory sharing. Consult the T&M Explorer online help for information on
setting these up.
Notes about VME Support
To use VME devices in your system, configure NI-VXI to see these devices
by using the Add Device Wizard in T&M Explorer. VME devices with
two blocks of memory in the same address space require two entries. You
can also specify which interrupt levels the device uses. VXI and VME
devices cannot share interrupt levels. You can then access the VME device
from NI-VXI or NI-VISA just as you would a register-based VXI device,
by specifying the address space and the offset from the base at which you
have configured it. NI-VISA support for VME devices includes the register
access operations (both high-level and low-level) and the block move
operations, as well as the ability to receive interrupts.
