Overview
Frequency Output Polarity controls how the output indicates the ON (active) state. The
default value,
Active High
, is appropriate for most applications. Your receiving device might
require an
Active Low
setting.
Procedure
Set Frequency Output Polarity as desired.
The default setting is
Active High
.
Options for Frequency Output Polarity
