7.7 Connection of the Ethernet
cable
During the wiring do not connect cable RS-
485 and the video cable.
Use of Ethernet cables with the following
characteristics is highly recommended:
• STP (shielded)
• Category 5E (or higher)
Use a shielded RJ45 connector on both ends of the
cable. The Ethernet cable shield on the operator side
must always be earthed via the connector.
Carry out the connections as described in the table
(according to the standard specifications: TIA/EIA-
568-B).
Connect the Ethernet cable to the RJ45 connector (
7.4 Connector board description, page 18).
