4.11.4. EtherCAT Communication (J2)
To use EtherCAT and Ethernet communication with the Gold Guitar, 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 Guitar’s EtherCAT interface using the above
mentioned connectors.
For other available options, please see Section 4.11.6.
Notes for EtherCAT 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.
