B.2.2 CR1000X Programs for CS700H
This section includes two CR1000X programs that measure the CS700H heated
tipping bucket rain gage. Both programs measure precipitation (mm), battery
voltage, and panel temperature. The second program also retrieves real time
status information by using SDI-12 protocol.

The CS700H will only communicate over SDI-12 when both
its sensor cable and power cable are connected (TABLE 7-2
and TABLE 7-3 ).
