wires preparation:
Power supply
This unit has two power supply options, passive PoE or external supply on the terminals IN
9-32VDC. Consumption in both cases is 1,5W (supply current is in both cases dependent
on the connected voltage).
Passive PoE
Power supply is distributed together with the Ethernet to the ETH
connector. Power supply is inserted in the data cable using the
common passive PoE injector. Supply voltage can be in range 9-
32V.
IN 9-32VDC
DC power supply 9-32V to the terminal „IN 9-32VDC“
Serial line is galvanically separated from Ethernet network and has its power supply on the
terminals V+ and GND. Supply voltage can be in range 9-32V.
Protocol
Data are sent to the Ethernet network through the TCP/IP protocol.
