It is important to note that the numbering of the Wheatstone bridge arms is not arbitrary. The resistor values are used in complex equations to calculate the strain or expected voltage. The resistor name definition can be summarized as follows:
The NI-9237 has 10 pins for each channel. These pins, with either the DSUB connector or the NI-9949 accessory, correspond to:
