7.1 Wiring

When Short Cut is used to generate the datalogger program, the sensor should
be wired to the channels shown on the wiring diagram created by Short Cut.

The rain gage is typically wired to a datalogger’s pulse channel (see TABLE
7-1).

Dataloggers listed in TABLE 7-2 have the capability of counting switch
closures on some of their control ports. When a control port is used, the return
from the rain gage switch must be connected to +5 V on the datalogger.
