Communication connections
The front communication connection is an RJ-45 type connector used mainly for
configuration and setting.
For RED615, the rear communication module is mandatory due to the connection needed
for the line-differential protection communication. If station communication is needed for
REF615, REG615, REM615 or RET615, an optional rear communication module is
required. Several optional communication connections are available.
•
Galvanic RJ-45 Ethernet connection
•
Optical LC Ethernet connection
•
ST-type glass fiber serial connection
•
EIA-485 serial connection
•
EIA-232 serial connection
Never touch the end face of an optical fiber connector.
Always install dust caps on unplugged fiber connectors.
If contaminated, clean optical connectors only with fiber-optic cleaning
products.
13.4.1
Ethernet RJ-45 front connection
The protection relay is provided with an RJ-45 connector on the LHMI. The connector is
intended for configuration and setting purposes. The interface on the PC side has to be
configured in a way that it obtains the IP address automatically. There is a DHCP server
inside protection relay for the front interface only.
The events and setting values and all input data such as memorized values and disturbance
records can be read via the front communication port.
Only one of the possible clients can be used for parametrization at a time.
