Digital Inputs

The "Digital In" terminals (page 11) are for easy installation of contact sensors (as opposed to using the RJ45 sensor ports).
Connect up to 8 different contact sensors having either 2-wire contacts (for open or closed circuit sensing) or 4-wire contacts (for
open or closed circuit sensors requiring 12V power supplies to operate). These sensors can be accessed from the Monitoring
->Digital Inputs item in the left side menu of the unit web page. The management is similar to Contact Sensor (page 31).
Note: The "Normal Status" of the contact sensor must be set to either open or closed, depending on the contact position
of the sensor connected to it. If the sensor connected has a normally closed switch position at rest, the Normal Status
should be set to "Closed". If the connected sensor has a normally-open switch position, the Normal Status should be
set to "Open".
