Connecting REF 542plus

To connect the Ethernet cable to REF 542plus, plug the RJ-45 male connector
into the female connector (port X70 of REF 542plus core unit) according to
the keying until it snaps into place.
To remove the connector, press the snap-in device in the direction of the
connector and then remove the connector.

Network devices required

To build a network, several additional devices are needed. The requirements
for network devices are described in this paragraph. In addition, there is an
ABB recommendation for each device.

Network cables

The cable connected directly to REF 542plus Ethernet port has to be a
shielded twisted-pair Industrial Ethernet cable, compliant with
IEEE8802.3 10BASE-T standard and of category 5 (CAT-5), with an
impedance of 100 Ω and standard RJ-45 male connectors at both ends.
