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, REM615, RET615 or REU615, 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 fibre 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.
Ethernet RJ-45 front connection
The IED 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 IED 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.
