The diagram above ignores line interface for simplicity.
When connecting several EtherCAT devices in a network, the EtherCAT master must always be
the first device in the network. The output of each device is connected to the input of the next
device. The output of the last device may remain disconnected. If redundancy is required, the
output of the last device should be connected to the input of the EtherCAT master.

4.11.5. Ethernet Communication (J2)
To use EtherCAT and Ethernet communication with the Gold Hawk, it is required to use an
isolation transformer. The most common solution is to use RJ-45 connectors that include
transformer isolation.
This section describes how to connect the Gold Hawk Ethernet interface using the above
mentioned connectors.
For other available options, please see Section 4.11.6.
Notes for Ethernet Communication:
•
The EtherCAT IN port can be configured as an Ethernet port for TCP/IP – see the EtherCAT
Manual.
•
It is recommended to use CAT5e (or higher) cable. Category 5e cable is a high signal
integrity cable with four twisted pairs.
