8.6 How Do I Use DO Ports?
The SmartLogger provides two DO ports, which support the reset of external
routers, audible and visual alarming for grounding faults, and output of correlated
alarms.

Before setting the corresponding function, ensure that the DO port is not set for
other purposes. Otherwise, the setting will fail.
