7.1 Connecting the Ethernet cable
Use RJ45 plugs and Ethernet cable. Connect the cable shield to
protective earth at both ends.
It is important to connect the cable shield to earth through
an earth clamp or to connect the cable shield to earth in
the connector.
CIM 500 is designed for flexible network installation; the built-in two
port switch makes it possible to daisy chain from product to product
without the need for additional Ethernet switches. The last product
in the chain is only connected to one of the Ethernet ports. Each
Ethernet port has its own MAC address.
