User's Manual Pub. 0300181-07 Rev. A
The module's input circuitry consists of four or eight single ended inputs. Inputs
are expected to be digital, but are built using comparators, so can operate with
analog signals. Hysteresis is built into the level detection circuit, so even very
slowly varying inputs can be digitized. Inputs have the option to be filtered with
a single pole RC filter, if the filter has been enabled by the user in their
application. The user is also expected to set the threshold level for their
application. Inputs are tolerant of the full input range regardless of the threshold
selected.
To use a channel, the corresponding input enable must be wired to a positive
voltage (see Specifications for input voltage range). It is recommended that
unused inputs have both the channel input pin and the enable pin wired to
ground.
