Appendix B. Sensorex’s Model

DO6200/T

Prior to June 2008, Campbell Scientific’s CS511 was Sensorex’s model

DO6200/T (see FIGURE B-1) instead of Sensorex’s model DO6400/T.

Programming, wiring, and some specifications are the same for these two

sensors. However, they look different and use different accessories.
