2.
NOTICE!
Risk of sensor damage. Use only PoE power sourcing equipment (PSE)
according to IEEE standards 802.3af or IEEE 802.3at.
Otherwise your power sensor can get damaged.
Connect the RJ-45 Ethernet connector of the sensor to the output of the PoE injec-
tor.
3. Connect the PoE injector to a power supply.
4. Connect the controlling host to the input of the PoE injector.
5. Establish a network connection between the power sensor and the controlling host.
3.6.3.2
Establishing a Connection to the Network
There are two methods to establish a network connection:
●
Power sensor and controlling host are connected to a common network
(infrastructure network).
●
Power sensor and controlling host are connected only over the switch
(peer-to-peer network).
In both cases, you can address the LAN power sensor as follows:
