Chapter 3. Using the RTU

Remember that the addIT A720/A723 remote telemetry units (RTUs) can be used either with the A730 system or as standalone systems with the A720B base station. The base station is discussed in “Using the Base Station” on page 9.

Opening the packages

You get several boxes when you purchase an addIT RTU. When you open them, you’ll see they contain:

•The A720/A723 RTU and ring clamp

•The solar panel, ring clamp, and connecting cable

•The aluminum rod and its cap

•A sensor and cable, one box for each sensor, with a fastening tie in each sensor box

Make sure you’ve received all the equipment and read through the instructions that follow. When you’re sure you understand them, you’re ready to install your RTU.
