Logic Inputs
The
7K Controller
supports six uncommitted
Logic Inputs
for detecting changes
in conditions from sensors at the repeater site. In addition, the three COR
inputs, the three PL inputs, and the Phone Line Busy input are capable of
acting as logic inputs in addition to their normal duties.
Logic inputs are scanned for a transition from the High state to the Low state,
and from the Low state to the High state. When one of these transitions is
detected, the appropriate macro is executed.
Logic inputs can be used for alarms or indicators of such conditions as
burglary, high water, high SWR, overtemperature, and so on. The inputs are
held high with pullup resistors, and must be pulled down by the sensor.
