Switch Settings (NI 781x R/783x R Only)
Refer to Figure 2-13 for the location of switches on the NI PCI-781xR and
Figure 2-14 for the location of switches on the NI PXI-781xR. Refer
to Figure 2-15 for the location of switches on the NI PCI-783xR and
Figure 2-16 for the location of switches on the NI PXI-783xR. For normal
operation, SW1 is in the OFF position. To prevent a VI stored in Flash
memory from loading to the FPGA at power up, move SW1 to the
ON position, as shown in Figure 2-17.
Note SW2 and SW3 are not connected.
