5.3.3 Connecting the i Core
The following are directions to electrically wire the LumaSMART i Core unit power, outputs, and
communication. The following sections outline the provided connections on the rear of the
LumaSMART
i Core.
Communications Output
The SmartDGA system requires a communication connection from the EZHub to either an i Core or
PC. This can be done via Ethernet or RS485 connection.
Ethernet Connection
The Ethernet connector is the normal
RJ45
(CAT5) standard cable. A shielded Ethernet cable must
be used. This cable is not provided as the required length will vary. The IP address for the Ethernet
connection can be supplied statically or by a DHCP server.
Note: For an EZHub using a static IP, you could change the IP address using the
Commissioning Tool via RS485 or Ethernet. The new EZHub IP address will take affect
only after you power cycle the EZHub. It is recommended to power cycle the EZHub
immediately after you change the IP address.
Note: The USB connection is only for uploading and downloading functions (such as
downloading data or uploading a new version of firmware).
When using Ethernet to communicate between the SCADA and the i Core, as well as between the
i Core and EZHub(s), the use of an Ethernet switch (not provided) is required. An example of the
network topology in such a case is shown in the following figure:
