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 merging unit 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 merging unit 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.
• PCM600
• WHMI
The default IP address of the merging unit through this port is 192.168.0.254.
The front port supports TCP/IP protocol. A standard Ethernet CAT 5 crossover cable
is used with the front port.
The speed of the front connector interface is limited to 10 Mbps.

Ethernet rear connections

The Ethernet station bus communication module is provided with either galvanic
RJ-45 connection or optical multimode LC type connection, depending on the product
variant and the selected communication interface option. A shielded twisted-pair
cable CAT 5e is used with the RJ-45 connector and an optical multi-mode cable (≤2
km) with the LC type connector.
In addition, communication modules with multiple Ethernet connectors enable the
forwarding of Ethernet traffic. These variants include an internal Ethernet switch that
