chassis and want to synchronize DAQ operations between the devices, one NI PXI-4472
must be installed in slot 2. Refer to the
information.
Note For maximum performance when using a non-PXI chassis, install the NI PXI-4472
in a slot that supports bus arbitration or bus-master modules. The NI PXI-4472 contains
onboard bus-master DMA logic that you can use only if the NI PXI-4472 is installed in
such a slot. NI recommends installing the NI PXI-4472 in such a slot. If you choose a slot
that does not support bus masters, you must disable the onboard DMA controller using
software. A PXI-compliant chassis must have bus arbitration for all slots.
