4.11.3. EtherCAT Communication (J2)
To use EtherCAT and Ethernet communication with the Gold Trombone, 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 Trombone’s EtherCAT interface using the above
mentioned connectors.
Notes for EtherCAT communication:
1. The EtherCAT IN port can be configured as an Ethernet port for TCP/IP – see the EtherCAT
Manual.
2. It is recommended to use CAT5e (or higher) cable. Category 5e cable is a high signal
integrity cable with four twisted pairs.
