The Digital Input test screen allows you to verify the proper operation of digital inputs and sensors. Digital inputs are
defined as meters (water meters, dosing meters, etc.) that count the number of closed contacts from 0 to 255 and
automatically restart back from 0. Other digital inputs (Dry contact, Ext. Pause, etc.) show either 0 when the contact is
open or 1 when the contact is closed.
Note that the card number is set according to its jumpers regardless to its location (local or extension box).
