OMP-MODL

Debounce:
Enables a hardware filter circuit that prevents short duration transitions
from passing into the icon. Debounce can be used to filter out contact
bounce from mechanical switches. The GPDI Debounce has a time
constant of approximately 50mS. Debounce should not be used when
counting signals of frequency higher than 10Hz or signals with On or Off
durations shorter than approximately 100mS.
FYI:
Contact bounce is a phenomenon that
occurs when a mechanical switch opens or
closes. During switching, the physical electrical
contacts inside the switch bounce against each
other a number of times before they settle to
their final state.
Depending on the duty cycle of the contact
bounce, the OMP-MODL may count these
bounces as events or transitions (count mode)
resulting in technically accurate but undesired
data. By enabling the debounce function, typical
short duration contact bounce will be filtered out.
Count Rising / Falling Edges:
The GPDI increments its accumulated count
when its input changes state from hi to lo or lo to hi. The User can specify
which transition (edge) is to be counted Rising (lo to hi) or Falling (hi to lo).
For example if a switch is connected to the input, the User can specify that
the count increment when the switch closes (Falling Edge) or when it opens
(Rising Edge).
