4.11.6. EtherCAT/Ethernet Line Interface
Ethernet transceivers require either isolation transformers or capacitor coupling for proper
functioning. The Gold Hornet unit does not include such isolation, therefore you must take this
into consideration when designing the integration board.
In Sections 4.11.4 and 4.11.5, a schematic connection with a standard RJ-45 connector that
includes transformer isolation is described.
Other recommended connection options are:
• Gold Hornet to an RJ-45 connector without an integrated magnetic isolation (e.g. M12
connectors). An isolation transformer is required.
• Connecting two EtherCAT ports on the same board can be done using capacitive coupling
or transformer coupling.

guidelines contact Elmo’s technical support.
