Alarming via Digital Output (=DO) Contacts
NOTE:
A ‘normal open output’ contact is created between the ‘C’ and the ‘NO’ pin of that
contact whereas a ‘normal closed output’ contact is created between the ‘C’ and
the ‘NC’ pin of that contact.
NOTE:
A standard Ethernet cable can be used on this connector.
2.2.3
PoE (=Power Over Ethernet) (only on NSM-A)
PoE is a technology that allows a Powered Device (=PD, e.g. IP telephones, IP cameras etc.)
to receive power from ‘Power Sourcing Equipment’ (=PSE, e.g. the Dragon PTN node).
Dragon PTN nodes are able to deliver PoE when one (or two) external PoE PSU(s) is (are)
connected to the NSM via the PoE connectors. A possible external PoE PSU and how to con-
nect it can be found in §2.3.2.
