Overview
Frequency Output Polarity controls how the output indicates the ON (active) state. The default
value, Active High, is appropriate for most applications. Active Low may be required by
applications that use low-frequency signals.
Procedure
Set Frequency Output Polarity as desired.
The default setting is Active High.
