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 447X
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.x). 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 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
PXI-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.x). Select Start»Programs»National Instruments»NI-DAQ
