KNX:
KNX is the standard that allows the automated and decentralized management of the technologic
plans of a big typology of structures: commercial buildings, factories, houses, public locals,
schools and so on.
KNX can be used in all the applications and functions for the building automations: from lighting to
control dampers, to the security, to the heating monitoring, to the conditioning, to the hydric
control and alarms, to energy management and so on.

ETHERNET:
The Ethernet port is used for the Modbus TCP communication and for programming the device.
The Ethernet connection must be made using Connector2 of HD67814-KNX-B2 with at least a Category 5E cable. The maximum length of the
cable should not exceed 1 m. The cable has to conform to the T568 norms relative to connections in cat.5 up to 1 Mbps. To connect the
device to an Hub/Switch is recommended the use of a straight cable, to connect the device to a PC is recommended the use of a cross cable.
