Pigtail End Wiring
Figure 9: Pigtail End Wiring
Note: Some SRS sensors may have the older Decagon wiring scheme
where the power supply is white, the digital out is red, and the bare
wire is ground.
Connect the wires to the data logger as Figure 10 shows. Connect the
supply wire (brown) to the excitation, the digital out wire (orange)
to a digital input, and the bare ground wire to ground.

Note: The acceptable range of excitation voltages is from 3.6 to 15
VDC. If you wish to read the SRS with the Campbell Scientific Data
Loggers, you will need to power the sensors off of a 12 V or switched
12 V port.
If your SRS is equipped with the standard 3.5 mm plug, and you
