1. Channel Type Button
The channel type selects between physical and math channel input types.
Frequency inputs are physical input channels.
2. Input Type Settings
For digital inputs there are 3 different sensor types to choose from. The
frequency type has two sub-types which affect the selects in the Data Ranges
screen. Select frequency if you are measuring purely frequency and do not
wish to convert to an engineering unit. Select volumetric flow rate if you are
measuring flow using a frequency or pulse output flowmeter.
3. Channel Map
The channel map provides a quick view of which channels have already
been configured (blue) and the currently selected channel (orange).
