Wiring the NI 9219
The NI 9219 has four 6-terminal connectors that provide
connections for four analog input channels. Connect the positive
signal of the signal source to the positive input signal terminal (HI)
and the negative signal of the signal source to the negative input
signal terminal (LO). Use the excitation terminals if your sensor
requires a separate excitation connection. Refer to Table 1 for the
signal names and Table 2 for the terminal assignments for each
mode. Refer to the
NI 9219 Circuitry section for information about
connections in each mode.
