NI PCI-4472 and NI PCI-4474
In a PCI system, any NI PCI-4472 or NI PCI-4474 can be the master.
The master broadcasts the ADC oversample clock to the other NI 447
X
devices using a reserved line in the RTSI cable.
For specific LabVIEW programming instructions, refer to
Synchronizing
Multiple PCI-DSA Devices
in the
LabVIEW Help
. In LabVIEW, click
Help
and select
VI, Function, & How-To Help
(or
LabVIEW Help
in
LabVIEW 6.0) from the menu.
For using NI-DAQ with other ADEs, refer to
Synchronizing Multiple
PCI-DSA Devices: Select_Signal
in the
NI-DAQ Function Reference Help
(for NI-DAQ 6.9.
x
) or the
Traditional NI-DAQ C Reference Help
(for
NI-DAQ 7.

). Select
Start»Programs»National Instruments»NI-DAQ
and the document title for the version of NI-DAQ you are using.

NI PXI-4472
To synchronize two or more NI PXI-4472 devices in a PXI/CompactPCI
system, one of the NI PXI-4472 devices must be located in PXI Slot 2.
This device is the master, and the PXI devices in other slots are slaves.
The master broadcasts the ADC oversample clock to the other PXI devices
on the PXI Star trigger lines and uses the RTSI 5/TRIG 5 line to drive the
synchronization signal to the slave devices.
For specific LabVIEW programming instructions, refer to
Synchronizing
Multiple PXI-DSA Devices

LabVIEW Help
. In LabVIEW, click
