Figure 4-3. AI CONV CLK Signal Routing
Figure 4-3 shows that AI CONV CLK can be generated from a number of
sources, such as the external signals PFI 0, PXI_Trig<0..5>, and PXI_Star,
and the Ctr 0 Internal Output.
Programmable Function Inputs
PFI 0 is connected to the front SMB connector of the NI PXI-4224.
Software can select PFI 0 as the external source for a given timing signal.
Any timing signal can use the PFI 0 pin as an input, and multiple timing
signals can simultaneously use the same PFI. This flexible routing scheme
reduces the need to change physical connections to the I/O connector for
different applications. Refer to Table 4-2 for information regarding the
available PFI 0 signals.
